The Vox VDL-1 looper has been a major part of my violin pedal set up for some time now. I bought it in August 2011 and have rarely done a violin gig without it. This is a review based on those 6 years of use and to explain why I think I need to get something else now.

As I wrote in 2012, there’s no such thing as a perfect looper. They all have their plus and minus points. Which one works for you depends on which plus points you need the most and which minus points annoy you least. I assembled this list of pluses and minuses for the Vox looper based on those 6 years of near constant use.

Good points

  • Two loops. They can be either synchronised to each other or not as you want. The mode is easy to set when you record the second loop and was one of the main reasons I looked into this looper over others available at the time.
  • Loop Effects. The VDL-1 has loads of effects that you can add to loops after they have been recorded. This is a great feature, you can pitch shift, add filter effects, stutters … oh all sort of things. You can also vary those effects with the footpedal while they are being applied to the loop. It’s such a cool feature. You can overdub effects over other effects too.
  • Live effects. You can also apply effects to the live signal that are independent of the loop signal – though they do get recorded onto the loop if you record it. I hardly ever used this as you can only have one live effect per preset.
  • Foot pedal for controlling the effects. Another great feature I think, it allows the loops to become something more than just a static background effect, they can make loops really ‘live’ and evolving.
  • Stop modes fade/delay and stop. In practice I only ever used the fade and stop options as the delay sounds cheesy. Again the fade option is a major feature for me as it allows me to change sections of the music gradually rather than suddenly.
  • Uses a standard 9V pedal power supply. It’s a minor point but useful when you have a lot of pedals and power bricks lying around!
  • The price. It’s only £199 new. It was that price when I bought it 6 years ago and seems to be the same now. It’s very good value.

Good points that I never used

  • Microphone input (with trim). It has an XLR socket on the back for a dynamic microphone. I never used it though.
  • Metronome/bpm option. Actually for me this was a bad feature as it’s quite easy to switch it on by mistake and I never needed it. When it was on, it forced loops to end on a whole beat – which was useless to me as the looper never knew what speed I was playing at so it just left empty space at the end of my carefully crafted loops!

Bad points

  • It has a gate built into it that you can’t bypass. When I first wrote my piece on loopers I thought it was the Vox being noisy. This isn’t true, it’s the BOSS RE-20 that hisses (it’s emulating a tape delay – rather too well). But the looper’s gate makes that noise come and go in a very conspicuous way when playing pizzicato. UPDATE: It does seem that the Vox was aggravating the RE-20 noise. Now I’m using the Pigtronix Inifinty looper it’s all gone quiet!
  • For arco playing it’s much less of a big deal to be honest, but once you know about it it starts to annoy.
  • No loop level control. Loops always play back at the level they were recorded at. You can assign the footpedal to control the loop level, but it counts as an effect so you can’t have any other effects applied to that loop unless you overdub the loop at a lower level and then change presets.
  • Changing presets causes a momentary dropout in the live channel. This one of my biggest gripes with this looper. If you want to change preset while playing … DON’T. You’ll get a glitch of about 1/8 of a second in your playing. The loops continue to play fine so I don’t know why it can’t keep the direct channel going too. It’s really irritating.
  • The effects are often of low quality. The pitch shifts and distortions are quite ropey if I’m honest. and the delays are quite basic sounding. They are nowhere near as good as the ones I have in dedicated effects pedals. For the price I suppose that’s to be expected, but it does make them less useful than you might like. Generally I mostly used the reverse, stutter and filter effects.
  • It’s complex to operate. There are quite a few operations where you have to press more than one switch at the same time … with your foot … without falling over … and playing a violin. With practice I learned to do this, but it does take practice.
  • It’s big. really big. Not heavy. Just big. There’s no way this would go on a pedalboard, unless it was a huge pedalboard with not much else on it. So you do have to carry it around separately. This also means it always has to be at either the beginning or end of the signal chain.
  • Low build quality. I think this has become a major problem for me now. The footpedal need regular tightening to stop it just flapping around and returning down to the ‘toe’ position all the time. The push switches fall off occasionally and when that happens the tiny springs disappear into the undergrowth of the carpet or blackness of wherever you’re playing. The internal boards come loose and the whole thing stops working until you kick it … then it works for a while and you need to kick it again. Then you need to take it to bits and just reseat everything because it’s been kicked around. Its not fun.

Things that other people have mentioned not liking that never or rarely bothered me

  • There’s a stupid bug where if you record a loop and don’t use it immediately (go to STOP rather than PLAY), it puts a small gap at the end of the loop, adding time to it so you lose sync. I only hit this once playing a piece written by someone else.
  • Only 90 seconds total recording time. I very rarely hit this though I’ve come near to it quite often. For others it’s been a deal-breaker though.
  • No way of saving loops. I always play live.

So I’ve been looking around at other loopers that might take its place. Current favourite is the Pigtronix Infinity – watch this space, I might review it in six year’s time 😉

Sometime ago I was approached by small local label “Don’t Drone Alone” and asked if I would like to make a release for them. Apparently they had heard my set for “A Working Day of Drone” and liked it 🙂

Once I saw “ripples” by genesis plays in our hearts on their website I knew they were going to be my kind of people, I’m a huge Genesis fan, so I agreed.

That release is now available to buy, you can get a physical cassette or a digital download. I do recommend the cassette, if only for the awesome artwork that Christian Harrop did for it. All my albums have had ‘artwork’ done by me and as I’m no artist I’ve generally used photographs … but I’m not a good photographer either. So it’s a real delight to have quality artwork drawn by a quality artist!

Side 1 is based on the sort of show I tend to do live, it’s mostly electric violin with lots of effects pedals. I’ve used the Blofeld synth on there to fill in some textures but there’s actually a lot less synth on there than you might think on first listen … I can get some great sounds from those pedals. The title “From The Carboniferous” refers to an abandoned quarry near to where I live that allegedly has strange creatures living in it.

Side 2 is a short ‘sci-fi’ style piece played entirely on keyboards. The Yamaha Montage to be precise.

Both tracks were recorded in a single take (with a little editting to remove the occasional pedal pops and bangs) from ideas I already had. Although they were done in one take, they are not necessarily the first take!

The tapes are limited to 50 copies so be quick if you want one of those. I should have some to sell at a gig I’m playing on the 27th of July at the The Fenton in Leeds.

For my 7th RPM Challenge album I’ve take a dystopian theme – yes, even more so than usual.

Due to various personal and domestic constraints I’ve had far less chance to prepare and work on the album this year. In fact I have had no preparation at all, so what is on there is largely a set of layered improvisations. ‘Introduction’ isn’t even layered, it’s a single take at the keyboard. For most of the tracks though, I’ve laid down an ‘idea’ track and worked with it by adding other sounds and instruments to make what, I hope, is a coherent piece of music.

The backing to ‘Restart’ was a late addition when a hard disk drive failed on me (luckily only a backup drive) making a strange a persistent rhythm I felt I just had to work with. So, despite starting this month with absolutely no plan at all I still managed to get 9 tracks totalling over 50 minutes. Oh the power of improvisation … and a 15 minutes ambient drone piece 😉

For those that care about these things here are the instruments I used on each track:

  1. Introduction: Yamaha Montage
  2. Trails of the City: Yamaha Montage, PreenFM2, builder taking my ceiling down*
  3. Cave Work: Octave electric violin with SY-300 guitar synth, Waldorf Blofeld
  4. Escape Route: MakeNoise Erbe-Verb+Mutable Systems ‘Clouds’, Electric violin, PPG softsynth
  5. Robot Dance: Emu Proteus, Yamaha Montage, PPG softsynth, spoons
  6. In my day this all was shoe shops**: Moog Sub37, DSi Tetra, Erbe-verbe, Octave Violin
  7. Restart: Failed hard disk, Yamaha Montage, Nord Lead A1,
  8. The Revolution will be short: Bastl Instruments Trinity Drum,  Nord Lead A1, Emu Proteus, Electric violins
  9. The End: Nord Lead A1, Moog Sub37, Emu Proteus

*I told you it had been a busy time.

**Track 6 was originally going to be called “In my day all this was Tescos” which is a better, and arguably funnier, title but I didn’t want corporate lawyers on my back.

As always, it’s a pay what you want download release on bandcamp.

In deep in RPM challenge mode at the moment (yes, it’s February!) as well as working on several other things at the same time (including an orchestra concert at the weekend .. eek!). But I did find time to film a Helicopter Quartet rehearsal.

This is a preview of a track we are working on for the new album, filmed live at Rock & Roll Circus in Leeds. We currently have 3 tracks recorded and mixed and we have 3 more to do – this is one of the latter. We have no date for the album release, it’ll be ready when it’s done.

In the meantime, I hope you enjoy this.

I was in my local friendly music shop asking about other things and, for one reason or another, ended up playing with the Roland BOSS SY-300 Guitar Synth pedal. The guy in the shop was enthusing about how well it tracked guitars – including slides and vibrato and my  next thought was “yeah yeah, but how well would it work on a violin?” In my experience tracking a violin pitch is very very hard. I’ve seen nothing that would do it reliably in either hardware or software, and it’s something I’ve been looking for for a long time now.

To cut a long story short .. IT WORKS! it even tracks the octave violin (which is tuned an octave below a normal violin so, on a 5 string instrument, makes it go down to the bottom C string of a cello). I stayed in the shop for a couple of hours playing with my violins on the device and was simply astonished about how well it worked. It is possible to confuse it, either with bad technique or pulling too hard on the low octave C string, but those are hardly major problems for normal use. And by bad technique I don’t mean tuning – if you play out of tune, the SY-300 will simply play the pitch you hit, I mean not placing your finger cleanly on the string which makes a dull grinding note on the violin anyway. If you slide all the way down a string – the SY-300 will follow you, if you use wide or narrow vibrato – the SY-300 will follow you. If you play loud to soft to loud in a single bow stroke – the SY-300 will follow you.

Amazing.

The guy in the shop thought it worked even better with violin that guitar because of the expressive effect of the bow on amplitude, and the ability to play long notes easily, it turns the SY-300 into a very expressive synth. It’s interesting to note that playing a synth via a violin (or guitar for that matter) doesn’t sound like playing a synth from a keyboard, it transfers the intrinsic ‘feel’ of the instrument onto the sounds made by the synthesizer – so in no way is it a replacement for a keyboard synth, it’s something totally different.

You need good synthesis knowledge to get the most out of the pedal, a lot of the factory presets are very guitar-orientated, made for a plucked instrument and often with lots of distortions added, so to get the best from a violin you need to get in there and make your own patches. As a violinist who also plays synthesizers this is easy enough for me, but people less familiar with subtractive synthesis might find it hard work to get what they want from it. This really is an expert’s device/

The architecture is slightly odd. It has 3 oscillators (with the standard virtual-analogue waveforms) each with its own filter, LFO and sequencer. Yes, the LFOs, filters and sequencers are per-oscillator! There are also 3 global LFOs (called Waves) that can be applied to the built in effects as well as the oscillator parameters. There are 4 effects slots which can be placed almost anywhere you like on one of two synth busses or the dry channel, and are of very good quality – as you would expect from a BOSS device. There is a good range of the usual effects, delays, reverbs, phasers, flangers & distortions – all with a good range of options. And also there are combined effects (delay+reverb for example) so you can make full use of those four slots. Most of the parameters of the effects can be controlled from the Wave LFOs. Although the way you configure those is rather clunky.

There are a few downsides. While it has MIDI in & out sockets (including USB) it does not send or receive MIDI notes, only control change and program change. I would also have liked more waveforms than just the standard saw,triangle, sine, square and maybe some interaction between the waveforms (eg FM). Also the software editor doesn’t work on Mac OS/X Sierra. Even the driver (which is supposed to work) crashed my system … and WHY OH WHY do MIDI devices need drivers anyway when they should just be class-compliant?! sigh.

But generally I think it’s an amazing device and if you’re a violin player who’s also into synthesis I strongly recommend you have a look at it.

I made a video about it with more information and examples

As I blogged earlier I’m enjoying using the Roli Seaboard with the Waldorf Blofeld hardware synth. So I thought I’d share how I create patches that make good use of the capabilities of the Roli with the Blofeld. In the video below I take a very basic sawtooth wave and turn that into an expressive (if still not especially beautiful) patch in the Blofeld. You can apply this knowledge to your own patches and make them ‘Roli Aware’ so that you can play them expressively.

The basic steps are as follows:

  • Set the oscillator bend range to 24 so that you can slide up and down the Seaboard. The Blofeld doesn’t allow you so bend more than 2 octaves so it works fine on the Seaboard 24 but might not be quite as good on the 49.
  • Add a low pass filter and set the cutoff down to 20, and allow the modwheel to modulate it. The Roli sends CC74 for the ‘slide’ dimension which is not very useful on the Blofeld so I mapped it to the modwheel (CC 1) using the Reaper CC mapper as shown below. Other DAWs might have similar capabilities. It’s quite easy to do in Max or Pure-Data too.ccmap
  • The Roli starts the slide with value 64* (the middle of the 0-127 range) when you press a keywave regardless of where you start, and modulates it down or up from there – so be aware of this when you create your patch. It needs sound good with the modwheel halfway. This is why I start the filter at 20 and not 0.
  • Set the amplitude envelope attack and release to 64.
  • Set the mod matrix to Velocity modulating AE attack at -64. This allows you to press the keywave gently to get a slow attack, and quickly to get a fast attack
  • Set the mod matrix to Release Velocity (Rel.Velo) modulating AE Release at -64. Now when you release a keywave quickly you get a quick release and slowly you get a slow release. These two options allow you to play legato and staccato with the same patch. I love this feature!
  • Set the mod matrix Pressure to modulate Volume +64 – this allows you to increase the volume just by pressing harder on the keywave.
  • Set the Amplifier volume to 0. Otherwise the Pressure modulator won’t do anything as it can’t make the volume any louder than 127.
  • Save the preset

That’s a basic preset that will work with the Roli in single channel mode. To really get the best out of it you need to create a Multi with the same patch in slots 1-10. That way the Roli can send a note on each MIDI channel and they can act independently.

Be sure that the multi preset you use has the MIDI channels differently for each part number – this is the default so that channel 1 goes to Part 1, channel 2 to part 2 etc. You also need to set the MIDI channel (in Global options) to Omni, or the Blofeld will only listen on one MIDI channel. I forgot to mention this in the video.

And that’s it! Even with a bare sawtooth that is quite fun, but once you get your own really nice sounds you can exploit to potential of the Roli Seaboard to it’s full, expressive maximum. Of course you can, and should, experiment with the values shown here they are intended as a starting point for making your own expressively played sounds.

Here’s the video showing the whole process from start to finish, along with a completed patch:

  • If you set the Seaboard to MPE mode (using the dashboard) then the starting point for the ‘slide’ dimension will depend on where you press the keywave. I don’t think this is mentioned in the manuals, Rol support told me about it!

It’s ages since I blogged about the Raspberry Pi system I started to put together last year and it has seen some serious ‘mission creep’ since then and become a hub for synths and keyboards/controller devices.

The original plan was simply to have a custom box that would allow me to plug a USB/MIDI keyboard into a couple of synths without having to use a laptop. The first incarnation of the software took input from the keyboard and directed MIDI channels 1 to 8 to the Waldorf Blofeld, and channel 16 to the ‘bass synth’, which was the Moog Minitaur. As the Moog Sub37 has its own keyboard that seemed like enough.

The first extension to the software was writing code to read data from TouchOSC and send that on to the Blofeld (like I did in this blog post using Reaper). This had the potential for portable gigs without a big keyboard (just 2 small synths and a tablet) with the added advantage of giving me extra control over some of the more awkward to get at (but useful) functions of the Blofeld while playing. The TouchOSC screen also has a page for the Minitaur too but it doesn’t get used, apart from preset selection, as the Minitaur has a nice front panel.

I’ve since acquired a few new input devices and a couple of new synths so it seemed logical to incorporate them into the software too. Now the application can do all sorts of flexible routing between keyboards/control surfaces and synths, all controlled by a TouchOSC ‘control panel’. TouchOSC also has patch editting/performance pages for  keyboardless synths (eg DSi Tetra) and one with complex editting needs (Yamaha Reface DX). There is also a cut-down version of the TouchOSC screen I have on my phone – see near the bottom of this post.

The Roli Seaboard Rise is detected and when routed to the Tetra or the Blofeld my code now automatically sets the right number of voices/MIDI channels on the Seaboard (4 for the Tetra, 10 for the Blofeld) and there is quite a lot of code in the Quneo input section for mapping the drum pads to expressive notes as I also blogged about earlier and also transparently mapping the sliders to the right controls on the connected synth so I don’t need a different preset for each instrument. It also takes the pressure and turns it into Polyphonic aftertouch when connected to the Blofeld (the only synth I have that supports it).

In addition to all that it has also grown a simple arpeggiator. This is there mainly for the nominated ‘bass synth’ (still the Minitaur usually) driven from a clock that can either be generated internally or received from an external system – in a CSMA context that would usually be Stuart’s sequencers. The sync code strips out any notes, CCs etc from the input and just sends on the clock pulses.

Small synth setup

In general the software automatically configures itself to work with whatever is connected to it, the idea is that it is mostly ‘plug-and-play’ to make setting up for gigs really quick and easy. As well as coping with really complicated CSMA setups with multiple input devices and synths, it is also really useful for smaller gigs – I recently used it for a couple where I was mainly playing violin but used a small synth and the Quneo. That would have been possible using the Keith McMillen MIDI expander box but this way I can also control the parameters of the synth easily as well as sending notes to it.

The software has been a roaring success for me. I don’t need to carry a laptop around with me so the weight is reduced, as is setup time. And the tiny box with the Raspberry Pi in it can go almost anywhere on stage without being a distraction.

If anyone is interested in seeing the software then email me. I would be happy to open source it if there is interest but it’s fairly specific to my setup as it stands.

  • The TouchOSC screenshots are taken from the host editor app – so slightly faked. I thought I’d get a better image than photographing the tablet screen.
