Title: Moogerfooger MF-10 FreqBox
Post by: Mark Hammer on January 22, 2007, 11:41:40 AM
This is gonna be a VERY interesting contribution to the market: http://www.youtube.com/watch?v=iiGOaAD9B2U

Almost a complete analog guitar synth in a footpedal. Match this up with the right additiona pedals and that's quite the arsenal.

It sounds a bit like an EH Guitar Synth not set up properly!

Also reminds me a little bit of the sound of my screaming meanie.

I'd like to hear it plugged into the MF-105 MuRF. 8)

Tried this at NAMM and I liked it very much.  What exactly is it doing??

From the description it sounds like the same basic idea as Tim Escobedo's Ugly Face circuit, using a guitar to reset a free running oscillator.  Their thing has different waveforms, FM, CV control, and follows the amplitude of the guitar, but sounds kind of similar.  It also sounded at moments (the crazy high frequency stuff, great!) like the Juergan Haible Wave Multiplier.

"using a guitar to reset a free running oscillator"

this is a technique I would like to understand better. any info would be great!

I have always wondered exactly what was needed to reset an oscillator...A square wave ? A super thin pulse?
Are there some common techniques for turning a squarewave (easy to get) into something that will Smoothly reset an Oscillator?

I have done many experiments with this and I never could get it to sound as nice as the FREQBOX. 
also, very often when you try to convert a guitar to square and then reset a vco with it, the higher notes are lower in volume than the lower strings.
so they must have found a way to compensate for this


thanks
