Re: Let's talk....guitar synths / guitar -> midi

hi Marcus,

I looked into it,
and I actually have the hardware to do it.
(mainly it's the hassle of the Roland p/u which
prevents me from getting those toys out)

The Axon stuff is pretty good, but they don't actually make the p/u
themselves (afaik) so if a Roland p/u is cheaper go for that.
Then you need the 13 pin cable, adds to the price.

The much cheaper route is 
http://www.sonuus.com/products_g2m.html
which is mono (no 13 pin).
...but then the freqbox is mono, so that's not an issue.
Tracking is a bit slower, but less warbling.

Do you already have the mp-201? 
if you need something that's Midi to CV for less money

That's the expense, then there's the troubles.
The Freqbox is designed for 1V/oct, but it's not ultra stable 
and you'll need to tweak an internal preset to get the scale
dead right (can be well in tune over 3 oct at least).
To follow the guitar dynamics put the dry guitar into the freqbox
audio in.

If you want the Moog MF-102 Ring Mod to play in tune
then that's harder. It's around 0.35V/oct so you'll
need to attenuate the control voltage to play a (fairly) in tune scale.
(don't know if the mp-201 does that, but it's easy enough 
to make your own attenuator with a 10k or 100k linear pot)


Once you got that going I can predict you'll want an MF-101
filter too :-)
