marchino72 Posted September 13, 2016 Report Share Posted September 13, 2016 Hi at all, I'm newbie for this forum. I'm guitarist and stompboxes DIYers from long time. My last project (builded, see images) was a programmable MIDI looper 16channels, for switch (via relays) analog audio signal (send/return from stompboxes) from guitar to amplifier. The goal was to change the mix of the guitar effects sequence. Now I want to build a box (similar at the BOME box product, but with more simple functions) that: - has a MIDI input program change (1-128), via MIDI pedalboard (or other device); - stores internally a routing path, via "translation matrix"; - has a MIDI output changed (in according with a translation matrix). For exeple: if I send the MIDI PC n.4 into the box, from output the box put the MIDI PC n.30. The matrix is simple (for sample): IN | OUT 1 | 25 2 | 25 3 | 25 4 | 30 ... | ... This type of project was discussed in this forum? Is similar at the "MIDi mapper" project? Thanks for your patience. Quote Link to comment Share on other sites More sharing options...
Phatline Posted September 13, 2016 Report Share Posted September 13, 2016 on the hardware side: this: http://www.ucapps.de/mbhp_core_stm32f4.html & this: http://www.ucapps.de/mbhp_midi_io.html software side: look if this handle your needs: http://www.ucapps.de/midibox_ng.html elsewhere: this code doesnt look very complex, you can program it on your own with MIOS, by simple looking @ the tutorials: http://www.ucapps.de/mios32_c.html Tutorial 2 (receiving midi) Tutorial 4 (sending midi) if you have any problems by storing "Presets" to SD-Card: the other question how you want to handle "what should it do" via UI (2x20 Display with Encoders under it and 2 Buttons?) aka Preset Editing - or should it do this things hardcodet (without UI) the hardest thing i had first was to setup the ToolChain, Environment Variables and so on (programming environment on Windows Linux Mac). and so on.
