In the parent patch the poly object assigns voice Patcher, the voice number is sent out an outlet so you can watch it Is received, the subpatcher sends a bang to thispoly~,Ĭausing it to output the instance or voice number. In this example patcher, pairs of incoming MIDI pitchesĪnd velocities are used to synthesize a sine tone. The poly object to create a MIDI synthesizer. You can then use poly~ in conjunction with Tells poly~ to send all subsequent messages to that instance Sending a target message followedīy an integer in the left inlet of a poly~ subpatch Patcher logic both inside and outside the poly~ object.Īnother way to allocate events using poly~ is through
Once the amplitude envelope out of line~ reaches zeroĪnd the sound stops, that subpatch's copy of thispoly~ tells poly~ thatĬlose the 'poly_using_mute' subpatch and open the one Level out of the *~ is nonzero - that iteration of the subpatch isĬurrently busy. The busy state was intended toĬorrespond to the duration of a note being played by the subpatcher instance,īut it could be used to mean anything. To the object until it is no longer busy. The instance is busy no note or midinote messages will be sent Non-zero signal or value sent to its inlet tells the parent poly~ that This instance is available for note or midinote messages. Or a value of 0 sent to its inlet tells the parent poly~ that
The thispoly~ object acceptsĮither a signal or number in its inlet to set its busy state. It scans through the copies of the subpatch it has in memory until itįinds one that is currently not busy, and then passes the message to it.Ī subpatch instance can tell its parent poly~ object that it isīusy using the thispoly~ object. When poly~ receives a note message in its left inlet, Instances of the subpatch dynamically using the noteĪnd midinote messages, and manually using the target message. Messages sent to a poly~ object are directed to different Needs to create when you tell it which subpatch to load. The poly~ object keeps track of the number of inlets and outlets it
You specify which inlet is assigned to which objectīy adding a number argument to the object - the in 1 objectĬorresponds to the leftmost inlet on the poly~ object, and so on. The objects in and out create control inletsĪnd outlets, and the in~ and out~ objects create signal The line~ object for 140 ms with an envelope on it.īut what about the in and out~ objects? SubpatchesĬreated for use in the poly~ object use special objects for inletsĪnd outlets. The mtof object, and outputs a sine wave at that frequency withĪ duration of 140 milliseconds and an amplitude envelope supplied by Haven't seen the in, out~, or thispoly~ objectsīefore, the rest of the patcher is pretty straightforward it takesĪn incoming MIDI note number, converts it to a frequency value using Let's look at the littlebeep~ patch for a minute. Subpatcher to show you the inside of the littlebeep~ object.
