 # VRC6 instrument editor
 
-VRC6 instrument editor consists of only three macros:
+The VRC6 (regular) instrument editor consists of only three macros:
 
 - [Volume] - volume sequence
 - [Arpeggio] - pitch sequence
 - [Duty cycle] - specifies duty cycle for pulse wave channels
+
+## VRC6 (saw) instrument editor
+
+This channel has its own instrument, a (currently, as of dev99) one-of-a-kind thing in Furnace.
+
+The only differences from this instrument type from compared to the regular instrument are that it:
+ - has a volume range of 0-64 instead of 0-32
+ - has no duty cycle range
