Korg Poly-61 Oscillator Waveforms
YouTube via rolandsh1000.
follow-up to this post.
"Just a short video showing the two "types" of sawtooth waveform on the Korg Poly-61. The Poly-61 has two oscillators: DCO1, a digitally-reset analog sawtooth-core oscillator (much like that on the Juno-6, -60, -106) and DCO2, a coarse, divide-down-style oscillator, based upon a CD4520 counter and some summing resistors.
I think both are musically useful, but it's telling that Korg gave the user the ability to turn off _only_ DCO2; DCO1 is always on!"
