The Sequence window is divided into two parts: the toolbar and the sequence table.
The toolbar contains four buttons which do the following in order: clear slot, find pattern, goto slot, and edit pattern.
The sequence table lists the patterns to be played when the current song is played. Both the pattern number and name is listed to the right of the number of each slot. There is a small icon to the left of each slot. Clicking on this icon pops up a menu of available patterns to be played at the current slot. Double-clicking a slot will play the pattern set for that slot. Dragging a slot will move the pattern it contains to a different slot. Option-dragging will copy the current slot's contents. Press return to edit the pattern contained in the current slot.
Notes:
You cannot have any “gaps” in the sequence table. You must fill the slots in order starting with the first slot. You cannot skip a slot or MacMod Pro will not be able to play or save the song.
