Tutorial 21MIDI Control:Using the poly~ objectHere’s an example of a patch which uses littlefilter~:The metro object is hooked up to both a counter and a random. The counter, which feeds thetarget message, cycles through the 16 voices of littlefilter~ loaded into the poly~ object,supplying each with a random number which is used to control the amplitude of thatvoice.A signal connected to an inlet of poly~ will be sent to the corresponding in~ objects of allsubpatcher instances, so the noise~ object in the example above feeds noise to all thesubpatchers inside the poly~. The second inlet (which corresponds to the in 2 box in thesubpatcher) controls the base frequency of the filters. Note that for the frequency to getsent to all poly~ iterations it is preceded by a target 0 message. You can open a specificinstance of a poly~ subpatch by giving the object the open message, followed by the voiceyou want to look at.176
