Groove

A groove is a sequence of speed commands that changes the speed every row. This can be used in place of long chains of Fxx commands to save pattern data.

Each module may store up to:

32 grooves;
255 groove bytes; (each non-empty groove uses 1 byte per entry plus 2 bytes)
128 entries per groove.

Generate
Generates a speed sequence x / y, or x ticks in y rows. Inputs for x and y are provided in the textboxes next to the button. The sequence won't be generated if the resulting speed is less than one.

Pad
Padding inserts the specified entry after each groove entry, so that the average speed is halved. All entries in the groove must be greater than the pad amount.

Expand
Halves the groove's average speed and works only if all entries are greater than or equal to 2.

Shrink
Doubles the average speed and works only when the groove length is a multiple of 2.
