osc tracking

2005-05-13 by cuari7

Since the 259e's (or the 225e) do not (yet) follow the standard 1 
V/oct to be able to play chromatic scales, I have done a quick fix 
which was inspired by a flaw seen in the early Moog VX-351's (with 
the fix being suggested by Dr Moog hisself!): feed the pitch out 
from one of the 225e busses into TWO inputs of a voltage 
mixer/processor, using two stacked banana cables (I use a Serge dual 
processor from my system). Turn the gain in one of them to unity 
(100%), and the other one to zero (initially). Let's call the latter 
input the "scaler" for reference. The mix out should go to the 259e. 
Now start playing scales, turning the gain of the scaler up until 
you achieve a perfect chromatic scale. Use the tuning knobs in the 
259e to get accurate tuning (use a tuner or another one of your 
synths for reference).
Neat, huh?
Want pitch bending? Use the bias knob in your mixer to go up or down 
(this works best if it has a center detent; perfect if it's spring-
loaded!).

Software updates schmuppdates!!
Now how can I get a clean sawtooth wave from these things...??

Which firmware rev are your 259e's running?  Which firmware rev is your 
225e running?  Mine track pitch from the 225e perfectly.

Really?
I dunno what # rev I have. I got mine in late Feb and Don says there 
haven't been any updates yet.
