The execution order of MIDIPoet composer's diagrams is top-down and left-right. For example, in this diagram:

When a MIDI note whose value is between 10 and 60 is received, the events (red blocks) are executed in the following order: t1, back, t2.



If the performance of a MIDIPoet piece is slow, you can try one of the following:
* Reduce the piece's area. See general properties of a composition.

* Reduce the screen's color resolution. In general, MIDIPoet will work fine with a 24 or 16 bit color depth.
* Reduce the resolution of the images used in the piece.
