- lack of arp to sequencer
- and only 5 CC sequences (across your whole setup, not 5 per track)
were my biggest feature disappointments when I first got my KSP
along with USB midi bugs (which appear to be fixed)
and the lack of an ability to send sequences to specific ports only (though it's still convenient to have a second port even if it's sent an identical signal... control over which port would simplify things when dealing with multi-timbral synths)
currently, my main issue is the lack of control over what gets forwarded to the midi output
I'm hoping new features are on the way!
