Probably destroyed component

Post by krinkel »

I think I destroyed one or more components while building my xoxbox.
The sequencer part works perfectly but the sound engine doesn't work well.
First of all the square wave is more silent as the triangle. Also the cutoff and resonance don't work, they affect the volume (cutoff has more efect on volume as the respnance).

I'm pretty sure every component is on the right place so I think I destroyed one or more components.
Does anyone have a clue what is wrong with my xox?

Also the triangle looks like a sine wave on my soundcard scope, and the square wave looks like cr*p

what triangle?
the oscillator produces a sawtooth wave, and the square wave is actually a waveshaped version of the sawtooth
sounds/pics might help

For Sawtoot

This is tune centered, everything else on lowest setting

This is tune and cut off centered, everything else on lowest setting.

As you can see only the amplitude changed


For squarewave

When tune centered, everything else low
