Korg Poly-61 Oscillator Waveforms

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!

This is so fascinating!!! Thanks for posting this!! I could listen to you talk about analog/digital technology all day lol might not interest everyone but its interesting to me! Now I just gotta add an oscilloscope to my shopping list lol (along with the poly61, polysix, yamaha cs20m, etcetcetc sigh~)

I wish everyone could see this... analog vs. digital.
