First post, hello!
Considered starting a new thread but there was this thread about the Memoplay already so yeah, y'know, not adding to the clutter or whatever
Just finished some experiments on a Memoplay, i got it with the express idea of trying to bend it into a weird bass-synth, get my dub on and stuff.
I'm very new to this bending business so i just did some pretty easy stuff:
added a line out, put a (clumsy) volume control to it since this thing is LOUD!!! Switched out the 10k tuning trim-pot for a 100k and a 500k in series (fine and coarse pitch adjustment kinda), it goes low and sounds really thick.
I also whipped together a LFO (proto-board version of the one from Casper that is for a S&S) that piggybacks on the batteries and connects to the circuit after the pitch control. I put a 2-pole switch so i can turn it on and off (kills both the + and -).
Anyway, fun to mess with and all but a problem/quirk also developed:
When i turn the pitch down to really crunchy levels it starts to wobble and fluctuate in pitch, is this because the cap takes longer to charge now that it's getting fed a lot less juice? I was hoping to find a way to make it more stable, maybe replace the cap for another value? Higher? Lower? Any thoughts?
Turning on the LFO circuit raises the pitch an octave or so, i'm guessing that's because it adds voltage to the circuit after the pitch controls, i tried hooking it up before the pitch controls but it was barely audible, i'll try some variations on the theme...
EDIT-
Runs on a variable wall wart now, thinking i should chop the battery compartment away, make room for cupcakes and tuna.
