The VM901 is a full-function oscillator module. It can be used in the audio range, or as a low-frequency modulation source. It accurately replicates the sound of the earliest Moog oscillator design.

Nice-sounding VA module. There is no discernable aliasing above or around the "analog" noise floor (which is about 82 dB below the fundamental for a saw waveform).
It gets out-of-tune with itself, which I discovered when poly-chaining multiple of them. Maybe that's part of the fun. I do wish there was a little detune knob I could turn down if I wanted to, though.
Overall, a useful and high-quality addition to the VM library.
