Ron there is no such thing as a dumb question.

I just check via Sonar and found out that yes the TTS-1 does respond to pitch bends. However the pitch bend range is 1 whole step up or down. You will have to look at a MIDI editor (I'm not sure if BiaB has one or not so others will have to come to your aid on this) or in the piano role and see how much of a pitch bend (PB) you have. If it's just a little then you may not hear any difference.

For example if your PB is -8192 and you are playing a D note you will hear a C. But if your PB is something like -25 you may still be hearing a D.

If you want more PB range you have to edit the TTS-1 tenor sax PB range: that is easy to do. If you do you should save that bank in the user banks other wise every time you open TTS-1 you will get the original tenor sax PB range.

Another option is to set your GR20's PB range, if possible, so it matches the TTS-1 range. That is if the +/- whole step is ok with you.

I hope this doesn't confuse you and I hope that it helps.

It's called the Heineken Maneuver.
