# Atari POKEY instrument editor

the instrument editor for POKEY consists of these macros:

- **Volume**: volume sequence.
- **Arpeggio**: pitch sequence.
- **AUDCTL**: audio control register sequence:
  - **poly9**: reduces size of LFSR. only on noise waveforms!
  - **high1**: runs channel 1 at 1.79MHz.
  - **high3**: runs channel 3 at 1.79MHz.
  - **16-bit 1+2**: enables 16-bit frequency mode by combining channels 1 and 2.
  - **16-bit 3+4**: enables 16-bit frequency mode by combining channels 3 and 4.
  - **filter 1+3**: applies a high-pass "filter" by combining channels 1 and 3.
  - **filter 2+4**: applies a high-pass "filter" by combining channels 2 and 4.
  - **15KHz**: runs channels at 15KHz.
- **Waveform**: wave selection sequence:
  - 0: harsh noise (poly5+17)
  - 1: square buzz (poly5)
  - 2: weird noise (poly4+5)
  - 3: square buzz (poly5)
  - 4: soft noise (poly17)
  - 5: square
  - 6: bass (poly4)
