Vowel and Speech model: Non-zero voltage at Harmonics-CV input has effect when attenuverter is closed #5

Closed xandramax closed 4 years ago

xandramax commented 4 years ago

For this model, the value of the Harmonics parameter influences the function of the LPG in regards to Morph and Frequency (as described in #2).

The issue here is that even when the Harmonics-CV attenuverter is fully closed (12 o'clock), non-zero voltage at the Harmonics-CV input offsets the transition point for the aforementioned behavior.

Steps to reproduce:

  1. Switch to the Vowel and Speech engine.
  2. Patch a clock into the Trigger input.
  3. Set the LPG-Morph attenuverter to maximum.
  4. Observe that there is no modulation of Morph. This is normal.
  5. Patch a cable from VCV 8vert (from the Fundamental plugin) to the Harmonics CV input.
  6. Do not adjust the Harmonics-CV attenuverter: ensure it is at 12 o'clock (value zero).
  7. Adjust the appropriate 8vert knob fully counterclockwise, so that negative voltage is sent to Harmonics-CV input.
  8. Observe that there is now modulation of Morph, as if the Harmonics knob has been turned counterclockwise.
