Command 0x26: Pitch bend (round trip, sign inverted)

Sets a pitch bend that goes back and forth the same number of times. Uses the change amount with its sign inverted.

Syntax

0x26, byte delay, byte interval, byte count, sbyte delta

Parameters

Parameter	Type	Contents
delay	byte	Time until the first change
interval	byte	Interval between changes
count	byte	Number of changes in one direction
delta	sbyte	Pitch change per step. Set with its sign inverted

Remarks

Performs the same setting as command 0x09 with reverse set to count and count set to count × 2.
The pitch rises by delta for the first count changes (because the inverted change amount is inverted again when applied), then falls by delta for the next count changes, returning to the original pitch.

For the detailed behavior of pitch bend, see command 0x08.

This command takes no time to process, and the following event is read within the same tick.

Note

count × 2 is calculated in 8 bits, so if 128 or more is specified for count, the total number of changes will be incorrect.
