The SSL 1200 “VCO 1” is a compact, high quality, precision voltage controlled oscillator for MU-format modular synthesizers, with an impressive number of functions for a single width VCO. Capable of accurate tracking over many octaves, it is also capable of acting as a relatively flexible low-frequency oscillator (LFO). With a time-tested sawtooth core, the 1200 uses highly matched integrated transistor pairs and quality temperature compensating resistors provide excellent stability.
One of three common waveforms – Triangle, variable width Rectangle, and Sawtooth may be switch selected to the Wave output, and a separate Sine output is continuously available.
External frequency modulation is switch selectable between linear and logarithmic. The depth of this external modulation is controlled by the CV AMT knob, and opens the door to many new timbres when modulated from other oscillators.
Sync (“hard sync”) input can be used to lock two oscillators together to prevent “beating” effects or to provide dynamic timbral variations. Modulating the 1200 VCO’s CV IN jack opens up a whole new range of sonic possibilities. Though not necessary in most cases, the input signal should be a clean rising edge (i.e. from a pulse or sawtooth wave) to achieve best results.
This one is a great oscillator with a huge spectrum of sound. And i love the PWM and the range of coarse. I could need more of these.
And i have to tell you this, i have 8 Q106 and they are great, but im using your 1200 as a solo oscillator, the triangle wave on this is nothing that i never heard before, i call it a soft, tender, romantic, sadness sound. Have a lots of Moogs and other stuff but this one…….!
I just wanted to let you know that the VCO 1200 I ordered from you arrived yesterday (1/25) and I’m very pleased with the quality of your products. After letting the VCO run for a couple of hours I was impressed with both its pitch stability and its audio performance. The saw and rectangular waves sound nice and fat, and seem to have plenty of overtones to play around with. It sounds especially nice when under some FM to create vibrato — a very musical sound. And it tracks 1V/octave perfectly throughout my keyboard’s 5-octave range.
Thanks again for a great product.
I really like the two [1200 VCO’s] I received previously. They play well with my DotCom system and sound great!
