When i try to use the 3-1 FM switch i get no sound modulations. the Panel display shows that i am switching it on/off but nothing happens to the sound. Even if i sweep thru the hi and low ranges of OSC 3 i get no modulation. why? is this broken? has this happened to you? I’m pretty sure i am not stupid here but i can’t believe it’d be broken for no reason. help.
Is the mixer turned up for OSC 1?
