So built a patched out Soundlab, with the ring-mod and sample and hold, with the single bus keyboard, I followed, all the directions given on ray's page, and some given by local tech's. No sound on the first try, made some modifications, then I got sound, but it is not working the way it should. Here are some questions, and some problems I think I have.
Any help that anyone wants to give would be greatly appreciated.

1) do I need to ground all the jacks?

2) Should the fine tuner V/supply be taken from the course pots?

3) the single bus keyboard doesn't seem to do anything like it should, but it does make the signal from the Soundlab louder. Sugguestions?

4) The sleeves of the jacks are very noisey when a patch is made, I assume this is grounding issue. More sugguestions?

Agin thanks for any help

1) No, I don't think you have to ground the patch jacks, but you have to ground the output I think Confused

2) Doesn't matter.

3) Sounds like you have connected the keyboard to the VCA? Connect the gate to the AR and the CV to the oscillators.

I had the same problem when I first turned my SL on. But I just had forgotten to turn the cutoff freq on the filter all the way up Rolling Eyes

I patched out the SL and I'm pretty sure I grounded everyone of those little buggers. (jacks) I used mono switching jacks cause I figured I would hard wire a few connections (Like the Arp 2600) so I wouldn't always have to patch for a simple set up, I never did. So I don't know if it was necessary, but I'm almost positive I did.

thanks for replying, I'm going to keep trying with it.
Ten years I was looking for a project like this, and Ray thankfully arose, and the people on this forum have been extremely helpful.
I'm shure I'll be posting again soon.
