Anushri DCO

What are the modulation sources for the DCO in the Anushri? I understand its pitch is MIDI controlled but is it modulated by any of the LFOs or Envelopes?

It is not modulated by the LFO and envelope - but by the modwheel if it is configured as a vibrato LFO. The motivation behind this is the following: by keeping the DCO frequency static and modulating the VCO frequency, we can create interesting FM / hardsync tones.
