Here we have the Synthesis Technology (SynthTech) E300 Ultra VCO. Well, a pair of them, actually. I'm comparing them here with the Sputnik VCO, which I've used in the previous two comparisons, and is serving as my reference VCO.

As with the last two videos, I do some back and forth with different envelopes, then LFO sweeps, then FM. The bulk of the video will be dedicated to FM sounds, as they demonstrate the greatest tonal differences.

As usual, envelope from Zadar, sequence from TINRS Tuesday.
