don´t know if it has been allready said:
OT internal:1.) Multiband-Distortion (3 Bands)
2.) a third Band on the EQ-fx
3.) disconnect tracks from T8 (if Master) ..... not every pad sounds good with compression
4.) Master-Track on different positions
ad. 3./4.: Track-Management in this case
5.) A Send-Track for routing with Send-Levels on different tracks
5.1.) Routing-Window with Levels
6.) since a track provides two FX, a single FX with a more versatile Reverb (and of course it would be more ressource-intensive) would be an awesome addition
Arrangermodus:different parameters from different Tracks on one or two pages
on MIDI-Side:Fader drives midi-cc´s for external gear ...... an algorithm which reduces the high-resolution faderway to the time-signature of midi .... sending simultaniously 6 different CCs on different channels should be possible
in other words: OT as a single workstation
