Hi, I have an Ody MKII (2813) which I 've been trying to calibrate. If I set it up as follows:<br>
<br>
osc. 1 keyboard tracking on<br>
osc. 2 sync off<br>
PW slider fully down<br>
filter freq. slider fully up<br>
VCA gain slider fully up<br>
osc. 1 (or 2) to audio fully up<br>
all other sliders down<br>
<br>
I've noticed that when I monitor the high gain output with a scope and
send a square wave from one of the osc's, I don't get a square wave
out. I get something that resembles a shark's tooth pattern and doesn't
sound square, it's sort of buzzy, not hollow. I've calibrated both
square wave ouputs from board B(II) using the osc. PW trimmers to get
nice looking 50% pulse waves. <br>
<br>
Further more, when I select the sawtooth on either osc. and monitor the
high gain, I don't really get the classic ramp, rather an initial spike
followed by an exponential downward curve with some small 'wobbles' on
the tail. Again the sawtooth output from board B looks like a nice
classic sawtooth.<br>
<br>
Clearly something's happening to the signal in board C(II). Does anybody have any ideas? All suggestions gratefully accepted.<br>
<br>
Cheers<br>
Chris<br>
