Apologies if this feature has already been requested, but I did not find it via search. This is something which would be very useful to me, because as it stands, it is impossible (for instance) to use portamento and filter cut-off commands at the same time (ala 303-style bass), nor, say, perform a panning sweep over an arp command. It seems to me that, if such a proposal were considered, it would be better to include it in the song properties menu, rather than on individual channels, in order to ensure channel grid width remains consistent.
