This example shows how to offset the pitch of a midi note by a random amount.
The way audio Max compiles audio signal networks is, whenever audio is turned on, MSP outlets send out the message ‘signal’. (In other words, that’s how Max knows how MSP objects are connected to each other, and thus knows how to calculate the audio signal network.) The [route signal] object detects the selector ‘signal’ and sends a ‘bang’ out its left outlet in response. The [t signal] object converts that ‘bang’ back into the message ‘signal’.
To use floating point numbers with the poly object separate the integer portion and the fractional portion. Then recombine them after the poly object, as in the example.
