I composed this track and performed it live while limiting myself to using three electronic instruments: Novation Circuit, PreenFM2, and a Moog Sub 37. Afterward I added a recording of a Tibetan tingsha bell that I captured using a matched pair of Rode NT5 condensers. The instruments were sequenced using the Squarp Pyramid, which might technically be considered a fourth instrument, but it is not a sound source.
The Korg KAOSS PAD KP3+ is a powerful beast. It’s great for realtime processing and sampling, but it’s not the best choice as a loop pedal. For one, the loop record length choices only include 1, 2, 4, 8, and 16 beats. You can adjust that after recording, but not on the way in. One shot samples can be any length, but they need to be triggered manually or via a sequencer. Furthermore, it’s not a pedal. If you want to trigger or record samples with your feet you’ll need a MIDI foot controller to do that. And not just any controller. It will need to be programmable so that you can send specific note values to the KP3+ that trigger each of the sample buttons.
This is the issue I decided to resolve for my continuously evolving live setup. More often than not I use a Rhodes electric piano with the KP3+ alongside a modest family of other gear. Playing two-handed while capturing Rhodes loops without audible gaps is impossible if you have to use a “spare” hand to do it. There are a number of programmable MIDI foot controllers on the market. Unfortunately, most of them are not fully programmable and are designed for changing patches versus triggering MIDI notes. An exception to this is the Behringer FCB1010, however, it’s quite large with twelve switches and two expression pedals. I only need four switches and can’t afford the space the FCB1010 would take up.
People are making all sorts of custom MIDI controllers and there’s tons of microcontrollers that can be used for this purpose. I won’t get into all the options, but a few examples include Arduino (perhaps with a SparkFun MIDI shield), Teensy, Livid Brain V2 or Brain Jr, and Highly Liquid’sMIDI CPU. It just so happened that I had a Highly Liquid MIDI CPU on hand that I was sent to me as a sample years ago. I had used it for a few experiments, but nothing on a permanent scale.
Following instructions on the Highly Liquid website I was easily able to reprogram the MIDI CPU via sysex and start testing it with the KP3+. In minutes I had a prototype working that was triggering the sample buttons properly. With that piece confirmed I ordered four momentary foot switches and a sturdy aluminum enclosure. I measured and drilled all the holes for the four switches, DC power, MIDI in, and MIDI out. I soldered it all together and started using it immediately. I’m very pleased with the results and hope to use the foot switch for years to come. To an extent it is future proof because at anytime I can reprogram it via sysex through the MIDI input. A second reason the MIDI in is useful is because I can still send the connect device MIDI from another source (MIDI clock for example). This works because the MIDI CPU can be configured to mirror the MIDI in to the MIDI out while merging messages that originate from the circuit board. Handy!
This was an inexpensive, easy, and elegant solution to a frustrating problem. Custom MIDI controllers are getting easier and cheaper to build all the time. I’d love to hear about your DIY MIDI controller projects in the comments below. Thanks for reading!
This Friday, April 21, 2017 will mark the 4th event we’ve affectionately titled, The Taming of the CPU. This time we have the privilege of being hosted by the Icehouse Minneapolis. Tickets are on sale now and available at the doors (opening at 10:30pm). The performers include myself, Mike Hodnick (Kindohm), Lucas Melchior (MKR), and Chris Leblanc with Michael Lund doing their famous modular-analog-video-liquid-light show. Expect to hear a broad range of electronic music from Kindohm’s virtuosic live coding to MKR’s Ableton prowess. I’ll be towing an all hardware rig including Rhodes electric piano, Moog Sub 37, a Pyramid Sequencer, and several other bits and pieces. Here’s the official spiel:
Taming of the CPU 4.0 brings together three award winning electronic musicians with two like minded visual artist to create a futuristic, immersive multi-media experience. Huge sounding hardware synthesis is combined with intricate live coding, and lush laptop arrangements while modular video synthesis and liquid light shows are displayed and synchronized to the music.

This Thursday, March 30, 2017 I will be performing two 30 minute sets of music with Graham O’Brien at the Walker Art Center as part of the Merce Cunningham: Common Time series of events and exhibitions. Our performances start at 5:30pm and 8:00pm in the Perlman Gallery and feature former Merce Cunningham dancers. Here’s a one minute teaser recorded during a recent rehearsal. The concert is free and open to the public. Visit the Walker Art Center for more details.
The Sound / Simulacra series is hosted by myself and Cody McKinney at Jazz Central Studios in Northeast Minneapolis on the fourth Wednesday of every month. If you haven’t made it any of these shows you’re not entirely out of luck. They are all being recorded and I’ll be sharing excerpts here on AudioCookbook. The first event in the series was a duet with Cody McKinney and Jeremy Ylvisaker on January 25, 2017. Their gorgeous improvisations were faithfully captured by sound recordist, Dave Kunath. Enjoy!
Jeremy Ylvisaker is a multi-instrumentalist from Minneapolis, Minnesota. He is a member of the indie rock bands Alpha Consumer (with Michael Lewis and JT Bates) and The Cloak Ox along with Andrew Broder of Fog, Mark Erickson and Dosh. He plays guitar in Andrew Bird’s touring band alongside Martin Dosh on drums and Michael Lewis on bass.
Cody McKinney works with sound by actively theorizing, organizing, practicing and challenging its properties. He studied bass and improvisation under many luminaries including: Johannes Weidenmueller, Bruce Gertz, Jim Black as well as composition under Kirk Nurock, Rory Stewart, Steve Lehman and Diane Moser. Cody’s group, Bloodline, along with John Keston and Pete Hennig, have recently recorded an album due out mid 2017.
