Audio In?

Afro88 · Posted: Tue Apr 19, 2005 8:42 pm Post subject: Audio In?

I'm wondering if anyone has any pointers on adding an audio in socket for the filter/vca section. I'd like to be able to run audio through the filter and vca, and possibly use it as a modulation source for osc pitch/filter cutoff. Any ideas?? I haven't built the patched out version, just the switch one. I take it I'd need to add another knob to the mixer section, and possibly expand the mixer circuitry to accomodate the extra audio in...?

So here we are again...... Any one want to repeat that lost audio-in thread? (Afro88? That isn't you Kofi? Are you still 'afromodulator'???).

yeah Admin, that's true! I remember during those episodes, I thought: "am I still stoned? ... and yet, I stopped smoking since 10 years now!

... so, here it is the shot:

connect an audio signal trought a 2.2k resistor to R47 (pin 2 side) and the other pole to the ground. I've tried with a cd player for long time without damages on the circuits! The audio signal can be processed by LFO, A-R ENV.GEN. and VCF. If you want to limit the signal in, connect a 100k potenziometer to the 2.2k resistor. I'm not an expert in electronic so I'm not really sure that is the right way do it but it works! ... maybe Ray could confirm us better way or not.
ciao

Cheers Paul! Nice and easy mod- just how I like it

Ahhhh, the topic gets unlocked. I remember asking for a duplicate topic that I started to be deleted, but then this one got locked and the real topic got deleted. I thought maybe I did something wrong, so I decided to ignore it and move on Shocked

Now that it's back, I meant to try out the audio in mod but when I moved my Soundlab to it's new case I had to do a bit of resoldering and things went a bit haywire. So I've been slowly working through the debugging process for the past week or so.

v-un-v: No, I'm not Kofi or afromodulator, sorry Smile

now if we look carefully at Rays schematics for Patched Sound Lab
the signal in spot is marked. through 200K resistor but a 100K + 100K potentiometer should work well

... yes, it should be the same input I figured out for audio signal Embarassed

Bumping it up.

Looking for answers still.

ALSO, how would one modulart, or incorporate the WSG or APC into the soundlab? Like maybe as a noise source?
