MIDI Channel
The Default MIDI channel is 6.
You can change this on the minerva.cfg file on the SD card.
Playing Samples using PC
If you just want to play some files, you only have to
copy them to the root folder of the SD card. To play back
one of the files use the MIDI PC command. The files are
assigned to the PC commands alphabetically. That way you
can play back up to 127 files. As an example, let’s
assume a SD-Card with six files: 0.wav, 1.aiff, 2.wav,
10.wav, a.wav and b.wav. These will be mapped to PC
commands like that:
0.wav → MIDI PC 00
1.aiff → MIDI PC 01
10.wav → MIDI PC 02
2.wav → MIDI PC 03
a.wav → MIDI PC 04
b.wav → MIDI PC 05
Playing Samples using CC
If you want to play back more than 127 files, or if you try to use the MINERVA on a shared MIDI channel, this is the
best way. Create a folder on the SD card with the name CC followed by a number. For example CC31. The files in
that folder are played back with the CC command 31. The files are assigned to the argument of the CC command
alphabetically. Let’s use the files from the example above and assume they are in the folder CC31. Then they will be
mapped to the CC command like this:
0.wav → MIDI CC 31 00
1.aiff → MIDI CC 31 01
10.wav → MIDI CC 31 02
2.wav → MIDI CC 31 03
a.wav → MIDI CC 31 04
b.wav → MIDI CC 31 05
That way you can choose the CC commands you use and use the MINERVA along side other devices on the same
MIDI channel. The MINERVA has some fixed CC commands, but these can also be changed. Refer to chapter
Configuration File for that.
CC MIDI Commands
CC # Function
102 0 Stop playback
1 Resume playback
2 Play Mode: Single. Playback is ended with the end of the track (Default)
3 Play Mode: Repeat. The track starts over at the end.
4 Play Mode: All. All tracks in the respective folder are played alphabetically. After the end of the last track,
playback is ended
5 Play Mode: Repeat All. Like Play Mode All, but after the end of the last track the playback continues at the
first track in the folder.
6 Set playback to forward direction
7 Reverse playback
8 Reverse playback temporarily (sets back to forward with next start of file)
10 Play Mode: MIDI Clock 1/4th notes. The playback restarts the file in the beat of MIDI clock 1/4th notes
11 Play Mode: MIDI Clock 1/8th notes. The playback restarts the file in the beat of MIDI clock 1/8th notes
12 Play Mode: MIDI Clock triplet notes. The playback restarts the file in the beat of MIDI clock triplet notes
13 Play Mode: MIDI Clock dotted 1/8th notes. The playback restarts the file in the beat of MIDI clock dotted
1/8th notes
14 Play Mode: MIDI Clock half notes. The playback restarts the file in the beat of MIDI clock half notes
15 Play Mode: MIDI Clock whole notes. The playback restarts the file in the beat of MIDI clock whole notes
16 Play Mode: MIDI Clock 2 whole notes. The playback restarts the file in the beat of MIDI clock 2 whole notes
17 Play Mode: MIDI Clock 4 whole notes. The playback restarts the file in the beat of MIDI clock 4 whole notes
103 0-127 Set volume of both tracks (0=mute, 127=full volume)
104 0-127 Set volume of left track (0=mute, 127=full volume)
105 0-127 Set volume of right track (0=mute, 127=full volume)
106 0-127 Fade Out currently played back track in steps of 100ms (1=100ms, 2=200ms, 127=12.7s)
107 0-127 Fade Out left channel of currently played back track in steps of 100ms (1=100ms, 2=200ms, 127=12.7s)
108 0-127 Fade Out right channel of currently played back track in steps of 100ms (1=100ms, 2=200ms, 127=12.7s)
109 0 Reset counter (Reset all in local mode)
1 Increment counter (Increment all in local mode)
2 Decrement counter (Decrement all in local mode)
110 49-71 Interval Sampling Rate (49 = -15 semitones, 64 = 0 semitones, 71 = 7 semitones)
111 0-127 Sampling Rate in steps of 409Hz starting at 20kHz (0 = 20kHz, 127 = 72kHz)
112 49-71 Master Interval Sampling Rate. Like CC 110, but stays at this rate and ignores the sampling rate from the files.
113 0-127 Master Sampling Rate. Like CC 111, but stays at this rate and ignores the sampling rate from the files.
