SQUID: Ability to Sequence per Voice / Midi CC
The squid is awesome to sequence synthesizers. But not really helpful for sequencing drum machine, as long as you don't want to map every drum voice to a track so you can use the awesome features of squid's sequencer.
Therefore I'd suggest to have a synth and a drum machine mode for tracks. In drum machine mode, there should be an extra layer where the bd, sd, clap, hihat can be assigned to the pads and sequenced individually.
Playing different drum voices on a drum machine is midi vice simply the same as playing different notes on a synth. and it's strange that you need a separate track for each "note" to be played on the drum machine to use the squid for coming up with new polyrhythms etc.
