This is really cool Tom. Smile

The big issue with the wsg is how many controls you can have on it. Mine has 14 pots, switches, leds and a line out jack, I doubt you'd fit that on a 1U front rack panel. I put mine in one of those cl ...

Don't know if I posted this before.

Do you also have to match the gain? I thought you did, but I could be wrong.

You could write "music" on paper, as a set of chords and a melody line, and at that stage it could still be interpreted as a country-rock ballad, an orchestral improv, or a punk epic. In thi ...

Thanks Dave,
I'm still not sure what I want. Just trying to get anything at the moment.

I think my soul has been on a rent/try/buy plan for so long now, that they've lost me in the system!! Wink

Thanks Jan. Smile

There are a lot of inter-board, and off board connections. We did that to simplify the boards, and maximise options, but it means you do have to make them VERY reliable.

A noise gate should be the last possible resort.
Remember that an electrolytic cap which LOOKS fine, might still be dry.

Is there any possibility that all that grounding has completed a ground loop?
ie Is there only ever ONE way back to the main ground connection?

Sounds great.
I was going through the schems today, of an old CMOS waveshaper idea I had years ago.
I'm looking forward to doing more with this stuff. Smile

Sorry rogerlatur,
I didn't read your post properly.

Yeah, I actually liked the flat top and bottom, if you put it through an LPF, the flats take it closer to a sine wave anyway. Smoothing out the Lunetta sound is always a nice option to have if you can ...

You can do a similar thing by putting all the outputs of a binary counter into their own XOR gate, except the MSB. The other input of all the exclusive XORs goes to the MSB. Send the outputs of the XO ...
