With my Axis-49 we needed to:
Max/MSP: a cute little graphical development system
travel along the little wires (black lines) connecting boxes. The
boxes do things to the signals, the top is input, the bottom output.
Here’s the flow sequence:
Gets the next midi note coming in, splits it into to 3 outputs:
You can double-click on the notein box to pop up list of the midi input devices and select one.
signals then travel along the connections (wires) to be translated. The
note velocity and the channel number go straight to the noteout box
unchanged. The note pitch goes to the coll object to be translated.
In this case the coll (collection) defined in table Axis49-wick.txt serves as a look-up table, the table is a series of paired numbers, with the input value matched to the left of the pair, the output value is the right pair value. Thus, with pair 84, 78; an input value of 84 (musically a C-5 gets mapped to a 78 (an F# ),
This table is easily edited in MS Notepad. When Max/MSP starts up, it will read this table. If like it, the Status box will show “coll; finished, 70 lines”. If not, it will show an error message.
Input “number box”
Display (shows “C-2” ) – shows the key hit by you in terms of what the Axis-49 sent out, as a note.
After I wrote the table, I wanted to shift the notes down an octave, so I added a little box that takes a number in the top, minuses it (see the little “-“ (minus) sign?) by 12 and puts it out the bottom
The 12 subtracted from the note value lowers it by an octave (12 semitones), I display the value in the little number box, but also pass it on two ways, one way goes to stripnote which strips out the note-off values – other wise the velocity would be zero when the note is lifted- and I pass the note on to the big yellow note display boxes.
The switch box
In the center is a little switch box, which allows me to turn on or off the translation
The little “value box”
This shows the midi note value as a number, not a note, for debugging. Shows (0)
Stripnote strips out the note-off values, so they persist on the display after the finger lets up.
2 big yellow “value boxes”
I made these big displays (shows “C-2” and 0) to show the last note had hit.
Read the 3 midi input values: outputs:
You can double click on the notein box to pop up list of the midi input devices and select one.That’s all it does – pretty simple, once you understand it.
