This patch shows how to mix detuned oscillators with modulation.

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’.

Similarly to the sample and hold object sah~, the snapshot~ object can be used to capture the amplitude of a signal at a specific instant.

The idea of “sample and hold” is to capture the amplitude of a signal at a particular instant in time, and hold it constant for a while. In MSP, the sah~ object allows you to do just that.

When sound waves are mixed together, be it mathematically within the computer or physically in the air, they “interfere” with each other.

This example combines seven pre-recorded saxophone sounds, slowly modulating several aspects of their playback to create an ever-changing mix.

This example repeatedly arpgeggiates the first 16 notes of the harmonic series based on the frequency 65.406395 Hz, which is the fundamental frequency of the open C string on a cello. The note rate can be adjusted anywhere from 1 note per second to 100 notes per second. The default initial rate is 8 notes per second.
