+  algoforte #3 (220105b)
+	code for first track of "algoforte01" - a two-tracker release on my
+	bandcamp: https://music.lukaprincic.si or https://bandcamp.com/lukaprincic
+	track 2 is a live performance of most the ideas in here with some changes
+	that seem to be necessary for live coding performance. :/
 
+	to use this code you need to be able to send midi out to either virtual
+	instrument that plays a grand piano (a sampler or similar). i personally
+	used Salamander Grand Piano SFZ loaded into Renoise.
 
+	you can also use disklavier if you have one handy nearby.
 
+	by starting MIDIClient.init (and waiting for a second or two)
+	and then m=MIDIOut(0) a midi output/input is created for SC.
 
+	the midi out from SC must go into midi input of the sampler/piano,
+	use test Pbindef to test. midichannel on sampler/piano: 1 (in SC: 0)
 
+	route audio output from piano back to SC and disconnect it from
+	main output (speakers). this is easily done using JACK.
 
+	requirement for this patch is also DEINDUGens which include JPverb
