Hi, Alwyn -
I remember you from the old original forum and we spoke of this. Do you have the latest Ver. 7 ROM installed? It seems to have helped a great deal. Also, I found out that if you plug in the two single foot switches, along with the 4-unit pedals, it creates a real problem so unfortunately, I don't use them. The 4-unit pedals are so close together, I set the number 2 pedal to off so I don't worry about accidentally hitting it when using number 1 pedal. It's a loss but it works. With Ver. 7 installed and this pedal method, I have had little trouble. My problem in the beginning was the glide would stick as well as the sustain not working correctly. Good luck. Glad you found your way to the site.
Scott
