thingiverse

First off, see the git here for code and more information: https://github.com/hunked/eightbuttonMIDIfootswitch This is an eight button MIDI footswitch that sends data over USB and regular 5-pin MIDI port at the same time. Currently there are 6 modes of operation selectable at boot. The selection screen can be returned to at any time by resetting the unit or pressing buttons 4 + 8 (top and bottom on the right side) together simultaneously. 1. MIDI Note Timed (on note sent on button press, off note sent after a preset time) 2. MIDI Note Toggle (press button once to turn on, press again to turn off) 3. MIDI CC Timed (same as mode 1 but with CC messages) 4. MIDI CC Toggle (same as mode 2 but with CC) 5. Program Change (pressing each of the 8 buttons sends a different Program Change message) 8. Settings Menu (change channels, MIDI messages, default options) If you do not choose an option the footswitch will start the default (mode 1) after a set timeout (6 seconds). You can customize all of the messages sent by the footswitch. Currently the following options are configurable from the settings menu: CHAN - channel for NOTE/CC/PC messages (set separately) NOTE - MIDI note numbers and velocities CC - Control Change numbers and on/off values PC - Program Change numbers DEF - default runmode (RUNM), menu timeout (MENU), how long before OFF note/CC is sent (NOFF/COFF) LOAD - load values from EEPROM SAVE - save values to EEPROM (changes you make to settings will not be stored unless you press this) There are two versions of the bottom of the housing: - 8buttonMIDI-bottom.stl has one 7mm in the back for a 5.5*2.1 DC jack or a 7mm reset switch - 8buttonMIDI-bottom-power&reset.stl has two holes so that you don't have to choose Please see my git repository for the full writeup, required parts to build, and code.
