I just bought an ESQ-1 and have been having a few different problems. My first problem was not being able to send a Sysex patch to the synth. I solved that by converting Sysex to MIDI and then it worked. (Still annoyed that SYSEX doesn’t work…)
My other problem that I can’t find a solution to is that the velocity doesn’t work. The sound is always at maximum. When I check with MIDI-OX, the velocity seems to work; The program displays values from 0-127. It seems like a hardware problem? Anyone experienced this?
