I am working on an Elka Synthex, and everything seems to be working except the sequencer playback.
It looks like the sequencer is accepting data. During RECORD, I can see the MIDI note data, and the sequencer eventually stops recording, indicating that the sequence memory is being filled.
To begin playback, I press the READY key and the sequence button, then when I press one of the "start" keys (low octave of keyboard) the processor steals a voice channel, leaving only 7 for live keys. If I attempt to start all 4 sequences, the processor steals 4 channels, leaving only 4 for live keys.
But no sound is produced, and no MIDI data is being transmitted.
Also noted, during the STEP MODE WRITE operation, if I press DELETE to remove the most recent note, the entire WRITE process is terminated.
Anyone out there in synth land have any good guesses?
