# VERA

this is a video and sound generator chip used in the Commander X16, a modern 8-bit computer created by The 8-Bit Guy.
it has 16 channels of pulse/triangle/saw/noise and one stereo PCM channel.

currently Furnace does not support the PCM channel's stereo mode, though (except for panning).

# effects

- `20xx`: **set waveform.**
  - `0`: pulse
  - `1`: saw
  - `2`: triangle
  - `3`: noise
- `22xx`: **set duty cycle.** range is `0` to `3F`.
