Hi Mystro!

Okay, now I'm not really sure of what exactly you're asking for. When you say tuning the 303's pitch to match the pitch of an instrument or record...why don't you just use the tuning knob?

I'm sure I've been misled by your query because the query itself, nor the answer to it, just couldn't be so cut-&-dry.

Hey, considering that you mentioned you no longer have the user's guide...are you maybe referring to the section of the user's guide, where it has a couple of diagrams on how to emulate the sounds of some instruments such as the electric, acoustic, and synthsized basses?

Or, are you asking how you should go about going "under the hood" of the 303 and playing around with its pots in order to modify its capabilities to successfully reach emulation of certain instruments?

Okay, let me know.
