The three outlets are PITCH \, VELOCITY \, -and MIDI CHANNEL from left to right. It is important to note however -that the data is outputted from right to left. Which means that the -first piece of information to be sent out the object is the MIDI CHANNEL. -; -#X obj 26 117 swap; -#X obj 26 156 pack; -#X obj 26 200 route 0; -#X floatatom 26 228 5 0 0 0 - - -; -#X text 102 117 Here \, [swap] is used to store the VELOCITY until -the PITCH information comes from [notein]. The next step will pack -the two together...but we have to ensure that [pack] receives the two -numbers in the correct order: PITCH first \, then VELOCITY. This way -\, using [route] we can determine whether or not this incoming MIDI -data is a "note-off" signal (i.e. VELOCITY = 0).; -#X obj 26 250 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 --1; -#X obj 46 312 notein; -#X obj 47 352 pack; -#X obj 47 377 route 0; -#X floatatom 47 402 5 0 0 0 - - -; -#X obj 47 420 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 --1; -#X text 122 308 The goal of the Miller's example at the bottom left -\, is to retrieve "note-off" signals from [notein].

As -a result \, the list will be outputted from pack BEFORE the PITCH information -is retrieved. [swap] is used to solve this problem by making sure that -the VELOCITY and PITCH are both received before packing them up and -sending them to the [route] object.; -#X text 50 248 This will "bang" only when velocity = 0; -#X text 22 282 THIS IS WHY THE ALTERNATIVE DOESN'T WORK?; -#X connect 0 0 2 0; -#X connect 0 1 2 1; -#X connect 2 0 3 0; -#X connect 2 1 3 1; -#X connect 3 0 4 0; -#X connect 4 0 5 0; -#X connect 5 0 7 0; -#X connect 8 0 9 1; -#X connect 8 1 9 0; -#X connect 9 0 10 0; -#X connect 10 0 11 0; -#X connect 11 0 12 0; -#X restore 28 569 pd millers_note-off_parser; -#X floatatom 44 319 5 0 0 0 - - -; -#X floatatom 94 319 5 0 0 0 - - -; -#X floatatom 143 319 5 0 0 0 - - -; -#X floatatom 112 440 5 0 0 0 - - -; -#X floatatom 161 440 5 0 0 0 - - -; -#X floatatom 211 440 5 0 0 0 - - -; -#X msg 37 243 2 2500 9 420; -#X obj 43 289 unpack f f f f; -#X floatatom 193 319 5 0 0 0 - - -; -#X text 14 10 [swap] is most commonly used to change the order of a -list.
