This feature has been submitted to the research and development (engineering) team. But as it stands right now, there is no official word if it will be implemented or not. The original ideal "pairing" of the Squid was to be with SP-16, and so each of Squid's tracks triggered a different layer of SP-16, and whether you were using drum samples, loops, or any kind of sonic material, you had high flexibility with what sounds should be on what channels.
Many MIDI devices which play drums actually have a special feature where ALL drums are available to trigger by receiving chromatic MIDI notes at an extreme end of the note scale, all on the same MIDI channel. This allows you to control all drums from a single track on Squid. May I ask you what device you're triggering with Squid, Tero?
