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.
