the mfb seq-01 and sps-1 GND-IM trigger

Monday 18 October 2010 - Filed under open

the machinedrum GND-IM machine sends (mostly) modular-level ready triggers, making it an outstanding x0x-style controller for a modular synth. on quick test, it appears to drive pressure points/brains and a doepfer a-155 with no hassles. however, the mfb seq-01 appeared to stutter and skip steps (in 16ppqn external mode). the seq-01 appears to be a little finicky about the trigger it receives to drive it. I found two solutions:

(1) Set the approximate GND-IMP values:
UP – 80-85
UVAL – 127
DOWN – 0
DVAL – 0

(2) Mix a positive offset voltage with the output of the GND-IM impulses.
