Hi, I have a Teisco S100P and it has a problem I can’t solve. When I play the keys in sequence, I hit a run of keys which sound as they are being modulated in some way or part of the cycle generating the sound is missing. If I switch the octave, the problem simply moves up or down the keyboard, but not in a logical way
When I transpose up of down, the problem moves as follows. Up position; 6 notes in middle of keyboard: C#, D, D#, E F, F#. Normal position 4 notes at top of keyboard F, F#, G, G# affected. Down three notes at very bottom of keyboard C, C# and D.
Here’s a link to a vid showing the problem:
Any help or pointers would be greatly appreciated.
