[sdiy] Reaktor and CV scaling...

[James R. Coplin]

I don't know if anyone else has messed with this, but I just stumbled on the
fact that I can use reactor as a CV generator for my modular rig! I don't
know if it is sound card dependent but I use MOTU stuff which gives me an
absurd number of analog I/O's. This might not work on other manufacturers
cards.

The output is not full scale (I'm not sure what it is, I'd have to get a
volt meter out). However, it is enough to be usable. I had a very complex CV
generating module which is basically a bunch of LFO's and envelopes all
locked to regular clock divisions and then summed. I was able to patch this
out into my Serge panels to control the cutoffs etc. I was also able to just
set up knobs and route them to other outputs for use as automated controls.
The only problem is the output isn't quite hot enough for 1v/oct. Can anyone
who is messing with this with success let me know of an amplification
circuit that would raise these CV's into the expected range? If you could
have a patchbay wired to amplify the output from these MOTU racks you would
have the capability to make one hell of a modular memory/controller. With 3
MOTU 24i/o's that would give you 96 outputs available to patch! Anyone else
messed around with Reaktor as a control source as opposed to a modular
replacement/effect?
