Building a very small euro EG and I'm wondering what everyone is used to their EG's outputting. I have some old stuff that outputs 0-10V and a lot of new stuff outputs 0-5V.

Any preferences here?

past the rails ?

Sorry, "into" the rails Smile

That being said, I looked at the schematic for the OCD distortion and noticed that the amplification stage slams the signal into the rails f ...

if you first multiply the 10Vpp signal just before the clipping points of an opamp, and then divide it back by the same factor -> gives you an unclipped output
(@15V that is roughly factor 3)

Phobos' WaveWiper module does that, if you only use one input.

Hi Alan, reading the operation instructions for that page I don't see that it does any clipping. I see that it does rectifying and ...

Hey guys,
I'm trying to find a schematic for something that can do some nice sounding clipping of a synth level audio signal. So the waveform stays untouched if below 10Vpp and starts to get clipped ...

Hey everyone,
I'm wondering what MIDI commands a multi-position selector switch should be sending?

For example, the 6 position rotary switches on a minimoog. Is there a specific MIDI command for ...

Finished product looks great diablojoy. Nice touch with the resistors between the pads too.

Hey all,
Just wondering if anyone is successfully using Thomas' VCO-1 on a 12V supply?
I know R23 and R43 change, is there any other changes that anyone would suggest making?

Hey all,

I just thought I'd share this video of the therevox ET-4 being used for an improv synth jam. He gets some pretty low bass notes towards the end of the video, so laptop speakers might not b ...

Hey Mike. Thanks for the link to your Therevox project. Fascinating stuff mate! Very Happy

Beautiful panel... just beautiful!
How did you do this?
