Atari TIA instrument editor
the TIA instrument editor consists of these macros:
- Volume: volume sequence.
 
- Arpeggio: pitch sequence.
 
- note: fixed mode works differently. it sets the frequency directly rather than the note, so it only goes from 0 to 31.
 
- Waveform: selects waveform to be used:
 
0: nothing 
1: buzzy 
2: low buzzy 
3: flangy 
4: square 
5: square 
6: pure buzzy 
7: reedy 
8: noise 
9: reedy 
A: pure buzzy 
B: nothing 
C: low square 
D: low square 
E: low pure buzzy 
F: low reedy 
- Pitch: "fine" pitch. fine in quotes as TIA doesn't have true pitch control at all.
