EMvibe

This is the performance software for the EMvibe. The EMvibe is an electromagnetically actuated vibraphone. The software uses ChucK and Max.

As ChucK can only have one public class per file, runMaxCtl.ck adds all of the necessary classes to the VM.

  • EMvibeMain_class.ck patches everything together. It also includes the MIDI listener.
  • EMvibeOsc2_class.ck contains the synthesis software
  • EMvibeVoiceManager_class.ck allocates audio channels and sets the shift registers on the instrument itself via a [Teensy 2.0] (https://www.pjrc.com/store/teensy.html) microcontroller
  • EMvibeReadTable_class.ck reads frequencies and MIDI note numbers from a text. Not used anymore; frequencies are hard coded
  • maxCtl.ck translates OSC messages (coming from Max) to the appropriate MIDI messages, defining things like envelopes, but also defining more complex behaviors.
  • EMvibePerformanceInterface_new.maxpat is the main way the performer interacts with the EMvibe. It includes a pitch-tracker for detecting incoming audio, a matrix for assigning different effects to different notes on the instrument, and a display that gives the user feedback about the state of the instrument.
  • Other Max files define presets and different effects.

NB Needless to say this software doesn't do much (anything, really) without the EMvibe itself.
