# VRC6 instrument editor

VRC6 instrument editor consists of only three macros:

- [Volume] - volume sequence
- [Arpeggio] - pitch sequencr
- [Duty cycle] - spicifies duty cycle for pulse wave channels
Add VRC6 support 2 Pulse channels: - 8 level pulse duty cycle, DAC mode(just ignores duty cycle)/pulse wave mode, 4 bit volume. - Furnace support PCM playback in pulse channels with duty cycle ignore mode. Sawtooth: - nothing but 6 bit volume (8 bit accumulator in technically) and 12 bit frequency (periodic). VRC6 instrument: - 6 bit Volume macro for finer sawtooth volume handling, also 3 bit Duty cycle macro for pulse channels. Duty, PCM mode command and Duty macro affects for pulse channel only. 2022-03-27 12:06:56 -04:00			`# VRC6 instrument editor`
