Yay I got sound but the sounds seem to trigger themselves.

I got mine constructed enough for sound finally. Very Happy

When I turn on my mini-synth I get the sounds triggered every few seconds. I will get a sound that lasts a few seconds, stops and then a few seconds later a sound again. Seems to be triggering without me connecting the two wires I have for trigger (they aren't wired to a button yet). Could having the repeat feature on cause this? I tried having it both on and off, doesn't appear to change anything. The sound seems to keep coming back forever without any action on my part.

check that you didnt jump any traces on the pcb.........if you short out anything on the bottom you might get some crazy reactions.

i have made a few mistakes with the wiring before and while the sound lab still makes sounds it is definitely not functioning as designed. after finding my faults (just wires going to the wrong place), the synth worked great.

Hope this helps. just check and check again!

Good idea to replace the solid copper wires. Even when they make good connections they are dangerous because they can break, sometimes inside the insolation. When this happens, it's really hard to identify the problem because everything looks right.

Quick questioned about wires. What does "UL" and "Recognized" mean in reference to a wire type. Almost all the wire types they sell at radio shack have that in the name.

UL stands for Underwriters Laboratory, an industrial research lab run by the insurance industry. It sets safety standards for many electrical components. In the USA, you can't get insurance if your house hasn't been built according to the building code (local building laws). Most codes require UL approved wires, sockets, switches, etc.
