Hmm... The basic system 2 appears to include an A-190-1... so I believe you could either start off with a low note, set the glide to slow, glide to the high note, then set the glide to a much quicker time, using MIDI controller data...

Or you could set it up so that pitch bend has a very wide range, and start off with the pitch bend wheel held down to the bottom, so you're starting off way out of tune and slowly glide up to the right note that way.

Might either of those work
