Stack overflow

Recursion, feedback loops, and unlimited untimed (as fast as possible) loops are not feasible in Max. In effect, you’d be asking Max to do an unlimited number of things all at the same time. Its scheduler (its internal “to-do” list) would get filled and it would be unable to do anything more. In computer lingo, its “stack” (its inbox of tasks to do) would overflow.

Random note choices

The left part of this example shows the use of the random object to make arbitrary note choices. Every time random receives a bang in its inlet, it sends out a randomly chosen number from 0 to one less than its argument. In this case it chooses one of 61 possible key numbers, sending out a number from 0 to 60. We then use a + object to offset that value by 36 semitones, transposing up three octaves to the range 36 to 96––cello low C to flute high C.

Delaying MIDI notes

There are many objects available for delaying events (i.e., for scheduling events to happen at a specific future moment). For timing and scheduling events, the most common object is the metro object (send bang periodically at a specified time interval), which can be used to trigger events, start/stop entire processes, or trigger a counter to step through a table or a coll or any sort of sequence of things.
