Tail-end Chris's VCO report
1999-07-07 by Christopher Jeris
Hey everybody ... got a job so I finally got some VCOs ... I got everything warmed up and trimmed properly and the pointy sine transient has indeed shrunk to 10 us wide. Verrry impressive sounding! The saw and pulse waves are attractively "in your face" without the irritating cicada buzzing I've heard from a lot of d*g*tal sawtooth waves, most notably my beloved Yamaha AN1x. The sine and triangle waves sound nice and clean. It tracks as finely as I can tune over 5 keyboard octaves, and would probably track beyond that if I weren't using a little bitty PA*A midi2cv converter :) All last night I was playing with the old "ring modulated vocals" trick, running out of a channel insert on my 1202vlz (to get preamplification) into the MOTM-110 X, with a sine tone for Y. When this is patched into the MOTM-120 SUB mode with the input mix set to SQUARE, and you turn up SUB 2 with a little bit of SUB 1 and SUB 3 for flavor, it sounds incredibly wicked. (The scope trace looks kinda like the output from my Blacet Dark Star, except modulated by vocals instead of noise.) Watch out Al Jourgensen ... I haven't tried CROSS mode yet. Got to build the other VCO tonight so I can try out CROSS and sync and all that neat stuff. My roommate Loren's laconic comment: "I think this `oscillator' thing is definitely a nice addition to the modular." peace, Chris
