+### Pure Data patches
+These patch has been used when writing the main code running on Teensy, to setup the audio layout and test things.
+The panel sends the CC on midi channel 1.
+The (very basic !) keyboard sends note on and note off on channel 1 too.
+
+You can use it by uncommenting the 4 usbMIDI commented lines in setup, that maps the  usbMIDI to internal midi functions. The majority of the audio functions of the synth can be accessed, without having a physical interface, like keyboard, knobs, switches, etc. The only thing you need here is the Teensy and an audio DAC.
+
+It has been used before the CC LSB were implemented, so maybe
