I'm actually using Yamaha FC7 for sustain. Plus an FC5 (I think) for the other programmable input.

I can't believe it!!!! I'm a real pro at last!!!!!!! I use the Sustain pedal and the EC5 just like my buddy DonM, I use the middle switch to start and stop the Acc. I use another one for the #1 fill. I use another for the stop mode that let's you hit a chord for a beat like doing, You made (bomp bomp) me cry (bomp bomp) when you said (bomp bomp) goodbye, "Ain't That A Shame

I think that is a good idea I always chasing it drives me crazy

One for sustain, one for VH on/off ...

Regarding the earlier reply from Don M. Whether I intend to sing or not, I find that having the words of a song in front of me, especially a song that has not been played for a while, absolutely essential for recalling a half forgotten tune. Simply by seeing the words of a song that I used to know well, I find that I can recall the tune much more easily. In some cases, I simply cannot instantly recall old or obscure songs in their entirety (or at all) without seeing the words.

Exactly!

I use two sustain pedals (I often find myself wanting to use sustain on only one side of a split then the other quite often) an FC-7 seven switch pedal, usually set up to Variations 1-4 (using auto-fill to call the correct fill), Performance up/down and Leslie Fast/Slow, then an EV-5 expression pedal.

However, I am finding more and more I would like to control with the FC-7 (you can now trigger the audio loops with the FC-7 instead of tying up 7 notes at the top of the keyboard, yay!) and Roland only provide the one global map. I have been trying to get Roland to allow the FC-7 assignments to be remembered in the Performance, NOT one global one... If you are a Roland user, contact Roland and add your voice to this, please.

Coming from an organ background in my youth, I don't find having so much at my feet any problem at all... after all, back in the organ days, I had at LEAST 13 'switches' at my feet and a swell pedal, and I was expected to play basslines with them! Triggering a variation change or choosing which side of the split I want to sustain is hardly anywhere near as complicated.

But in user demo after demo, I hear flubs as we have to stop playing, dash over and hit a button, and rush back to the keyboard hopefully in time for the next change. Play something with a ton of changes (and often, the busiest chord density comes at section boundaries, the EXACT time you usually find yourself needing to ask for fills, or OTS changes, etc.) and you may find yourself short-changing the music to ensure you hit the button.

Personally, I'd rather do the button pushing with my feet, so I don't HAVE to make that choice... Do I keep playing, or do I hit that button? Can't do both with only two hands!
