I do believe that there is a new Khai posting on the forum.
A big welcome to the new Khai and my apologies to the old Khai for many things that were said.
Regards,
Walt
ps: I too would certainly like to be able to control the tempo in a smooth manner via a foot pedal. I might have an idea but it would require digging into the innards of the instrument and making some alterations. I'll have to give it some more thought.
