What is Your Top Programmable MIDI Controller?

Posted on March 10, 2011 by John CS Keston

I’m looking for a programmable MIDI controller for the Roland MKS-80. I have almost resigned myself to building my own MIDIbox 64, but if something pre-built and inexpensive that will serve the purpose is out there I’m willing to consider it. The most attractive thing I’ve found so far is the CME Bitstream 3X (formerly Wave Idea), but I’m not exactly thrilled about CME products. I have a CME UF7 keyboard controller and I’m not that happy with it. I’d love to hear from someone with a Bitstream 3X about what they think of it feature and construction wise.

Other interesting devices are the Novation SL MkII series (a little short on knobs and sliders) or the Doepfer Drehbank (discontinued). Another possibility is 3 Korg nanoKONTROLs and a USB hub. I’m using one right now with three scenes programmed to control everything on the MKSK-80, but the scene switching is cumbersome, and I loose my positioning on parameters after switching scenes causing jumps in the programming. However, having three of them would solve that problem. Unfortunately, they are not programmable for sysex (required to interface with the MKS-80), so I’d need to map them through editor software, eliminating the potential of a computer free setup.

Roland MKS-80 Super Jupiter Repair

Posted on March 6, 2011 by John CS Keston

I recently purchased a Roland MKS-80 in need of repair. Several things were wrong with it including the tuning knob, dynamics slider and “insert cartridge” errors when trying to change the patches from the front panel. Without being able to tune the synth or utilize the dynamics, the instrument was effectively unusable, but I decided to buy it anyway in the hope that it could be repaired. After several days and more than thirty hours of research, parts swapping, and troubleshooting I managed to get it working properly. Read on for an illustrated story of the repair process and audio from the fixed unit.

VidiSynth Generates Audio from Light Sources

Posted on February 28, 2011 by John CS Keston

Expanding the VidiSynth Part III from paul sobczak on Vimeo.

Paul Sobczak has recently posted some videos documenting the VidiSynth. It’s has four independent oscillators that are controlled by either potentiometers or inputs from other sources. In this case he is using light dependent resistors or LDRs that suction onto a display. As video plays on the display the pitches change on all four oscillators based on the position of the LDR on the screen producing corresponding sounds. I’m not sure how Paul plans to use this, but I’m anticipating some interesting generative work with a synesthetic theme.

Weird Sound Generator Meets Memory Man

Posted on January 27, 2011 by John CS Keston

This evening I introduced the Weird Sound Generator (WSG) to the Electro-Harmonix Deluxe Memory Man delay. The two of them hit it off and the next thing I knew was that someones jack went into someones input and some completely unprotected signals went down. A little mood lighting later and… here’s the result of the union.

Example of Posc from Live Performance

Posted on January 16, 2011 by John CS Keston

I extracted this recording of the Posc from a performance of Words to Dead Lips at Intermedia Arts last November. I left the processing on it that I had used during the performance. At some point I’m going to acoustically record one of the “noise shields” that built for the dancers to use in the piece as a comparison. The “noise shields” have a distinctive sound tailored by the amplification, speaker, and the body of the instrument that is quite different for the direct sound below.
