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.
