Hi NickG,
You're not alone. Received my KSP today, spent 6 hours to solve the exact same problem. No luck.
Basically what I want from this device is to playback my modular system, using the 4 voices with CV/GATE, and why not the drums triggers outputs....one day...
I'm not concerned about the internal sequencer, I probably will never use 70% of the KSP possibilities. All I want is a nice MIDI to CV option with a keyboard, using 4 voices. On the paper, that's what I need....
...but for now, I can only record MIDI clips, and just like you, there is no playback. I can flawlessly record MIDI notes, using the 4 tracks, and playback
plugins (Ableton's stock or Arturia's plugins). So on this, for me no issue. But nothing from my
modular using the cg/gate outs.
And just like you, I can see the leds playing above the keys, but no sound. I don't know where is the problem. Have to mentionned that connecting the KSP to my modular using the CV/GATE works, I can play and hear sounds. But, no sound when i press play in Ableton to play whatever i have recorded.
I have tried every possible ON/OFF/Track/Sync/Remote, Input Output, Midi port options that you could possibly imagine. Creating External Instruments etc.... Extremely frustrting.
