This time around my work is entirely rooted in FM synthesis. Particularly around my explorations of the amazing PreenFM2. I have designed a Max for Live patch that allows me to degrade, morph, and/or scramble sets of parameters on the synth. This is similar to a device I designed for the Yamaha TX81Z. This process creates an algorithmic approach to the sound design.
I have titled this series MODULATOR and recently made an album (unreleased) of material based on the technique. There is a lot to mine here, so I am finding that while I prepare for ISSTA a whole new range of material has emerged. These new compositions developed through a sequence of stochastic, deliberate, and arbitrary processes. Through algorithmic and improvised methodologies textures evolve beyond aesthetic considerations allowing peculiar, harsh, and even grotesque sounds to emerge. Have a listen to this series of clips I recorded while practicing for the upcoming performance:
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!
Squarp’s Pyramid sequencer just got a new firmware update with the prestigious versioning of 1.0. I’ve had mine now for almost a year and have seen a slew of software updates during that time. The new features in 1.0 include a new LFO MIDI effect. These LFOs can be chained together creating all sorts of possibilities. Continue reading →
Graham O’Brien is an exceptional and inventive drummer, composer, and producer. It has been my privilege to play with him at dozens shows and on at least five separate projects over the last eight years. His latest solo endeavor is a series of five videos titled Drum Controller. Graham had discussed his goals for the project with me, but when I saw/heard the videos I was immediately impressed. I wanted to know more about how he was able to trigger these beautiful and complex electro-acoustic arrangements without touching anything other than his minimal kit of kick, two snares, high hats, and a ride.
Last July I wrote an article titled, How Do You Do Your Live MIDI Sequencing? In the article I expressed my frustration with the ubiquity of step sequencers and lack of modern hardware sequencers that handle live recording and polyphony. In December, 2015 I became one of the lucky few to own a Pyramid sequencer by Squarp. Pyramid is an amazing instrument that does everything that has been lacking from most modern sequencers, plus an ever widening array of advanced features available as MIDI effects. It’s hard to contain my excitement about this machine! Squarp has been extremely communicative with their customers through email and their online forum. New releases have been frequent during its life cycle, and I expect many fantastic new features and advancements in the near future. Here’s a few of Pyramid’s current capabilities that I find exciting:
1. Live recording of polyphonic notes with velocity, pitch bend, channel pressure, mod wheel, and continuous controllers. Notes are recorded without quantization unless the Quantizer MIDI effect is applied to the track. What makes this exciting is that although polyphonic and un-quantized recording is common in software it’s rare in new hardware sequencers.
2. Simultaneous track lengths and time signatures are independent of each other. The track lengths are not limited to bars, but can be adjusted down to individual steps. For example, a five bar and three step phrase is possible. This feature allows for polyrhythmic sequencing which I’m very excited about.
3. Pyramid projects are saved on a standard removable SD card as a collection of MIDI files. Although there are plenty of editing features in Pyramid, if you need to for any reason, the files can be edited on a computer in your favorite DAW. You can also create or import MIDI files from elsewhere into a Pyramid project!
I’ll share some of the music I’ve been creating with this beast soon. I could (and will in future posts) go on about euclidean rhythms, step editing, sequencing tracks, chaining sequences, and CV/GATE i/o – all capabilities that Pyramid has, but for now take a look at this collection of tutorial videos that Squarp shared just yesterday: Continue reading →
