- `x` is the time.
- `y` is the shift.
- set to 0 to disable it.
- `15xx`: set envelope mode.
- `0`: envelope + length counter (volume represents envelope duration).
- `1`: length counter (volume represents output volume).
- `2`: looping envelope (volume represents envelope duration).
- `3`: constant volume (default; volume represents output volume).
- pulse and noise channels only.
- you may need to apply a phase reset (using the macro) to make the envelope effective.
- `16xx`: set length counter.
- see table below for possible values.
- this will trigger phase reset.
- `17xx`: set frame counter mode.
- `0`: 4-step.
- NTSC: 120Hz sweeps and lengths; 240Hz envelope.
- PAL: 100Hz sweeps and lengths; 200Hz envelope.
- Dendy: 118.9Hz sweeps and lengths; 237.8Hz envelope.
- `1`: 5-step.
- NTSC: 96Hz sweeps and lengths; 192Hz envelope.
- PAL: 80Hz sweeps and lengths; 160Hz envelope.
- Dendy: 95.1Hz sweeps and lengths; 190.2Hz envelope.
- `18xx`: set PCM channel mode.
- `00`: PCM (software).
- `01`: DPCM (hardware).
- when in DPCM mode, samples will sound muffled (due to its nature), availables pitches are limited and loop point is ignored.
