all base pedals only play one note ....f sharp...i have serrvice manual
visual look at circuit diagram...cant fathom out faulty component...
Hi,For me to help you'll need to provide more information about the type of bass pedals you are working with.For what you've described, it would seem that either the note control signal being sent is always the same, or the oscillator is unable to track it. I would check the note signal first. If it's OK, then something in the tracking is off. For example, on an older system, the note gate is being triggered, so the note sounds, but the control voltage of the note value is always the same, so the note never changes.On newer MIDI-based equipment it would be different.James
