MidiGAL is yet another MIDI controller device inspired by Mutable Instruments MIDIpal.
Although MidiGAL can run Mutable Instruments MIDIpal firmware, there is a number of other firmware variants that were developed specifically for MidiGAL:
- MidiClk — MIDI clock tester/generator
- MidiArp — advanced MIDI arpeggiator
- MidiSeq — polyphonic MIDI step sequencer
MidiGAL differences from MIDIpal
While MidiGAL hardware is almost identical to the original MIDIpal, there are some minor differences:
- 8×2 LCD (MIDIpal uses 8×1)
- tactile switch (MIDIpal has no switch)
- external EEPROM (MIDIpal has no external EEPROM)
- 4 x I/O ports (MIDIpal has 8 of them)
Bill of materials: MidiGAL BOM
Build instructions: Building MidiGAL
Board outline: midigal_dim
Case files: MidiGAL_Case_4 (thanks to Altitude909)
Eagle files: [tbd]
This case requires 4 x 10mm (top) and 4 x 22mm (bottom) standoffs.
It is compatible with both long (25mm) and short (20mm) shaft encoders. Long encoder works with pretty much any 6mm D-shaft knob, whereas the short one needs a knob with 8mm skirt or less.
It expects rectangular switch button, the one that is specified in the BOM (TACBLK)
The .EPS file is formatted for Ponoko/Formular but any place should be able to accept it.
