Problem with Grandmother

Post by Lamagalula » Sat Aug 13, 2022 3:01 am

Hello everyone! Two weeks ago I’ve played a gig on my synth and everything’s gone fine like usual! After show I’ve put grandma to box and went for holidays. Yesterday when I’ve try to play on it I was surprised that synth not giving any sounds. After couple hours of digging I know this…

MIDI signal form Grandmother keyboard is sending to computer
MIDI signal from computer to Grandmother work fine and grandma giving a sound
VCO MODE switch work only I drone mode and then OSC start play lowest frequency is possible (clicing)

I can’t play using grandma keyboard, mod and pitch wheel also not work properly.

Is anyone have similar issue, my first suspension is VCO MODE switch.

Thanks for help

I suppose by VCO MODE SWITCH you mean VCA <- A!
MODE switch?
If the MIDI OUT reacts correctly to the three different positions of this switch, this control cannot be the problem cause.

First I would check if it got some mismatch in the internal memory regarding local note on/off. Global settings D#2 + G0 (see manual).
