Maybe check out http://www.ucapps.de/mbhp_aout_lc.html I'm not sure what app would suit you best though. NG is probably the most flexible, depending on what you want to do.

Cool solution, looks great! The skirts for the knobs are a nice touch. One thing I wonder about is if heat would build up here, as the free air space in the case is less and the panel is also an insulator. The SIDs are on another PCB of course.

Like this? https://github.com/midibox/mios32/blob/master/apps/sequencers/midibox_seq_v4/core/seq_ui_opt.c The "list" of options is written in order at ca. line 40 "local definitions"

Congrats, really glad that you got it working! Really it was TK. who had the magic touch here, still after 2+ decades of building these things. :)

How about if you put core 3 (or 4) into the fourth spot and leave the third spot empty? If it fails then you know that the fourth spot on the PCB has a problem. Measure conductivity from the pin of the socketed chip to somewhere else on the PCB, it could be that the socket itself does not connect the pin to the PCB.

Is it anything to do with the device ID that was flashed? http://www.ucapps.de/mios_bootstrap_experts.html

Would the numerical order of options stay the same if the features were rearranged into groups? The documentation and countless forum threads refer to specific options/#, so it would be confusing to renumber or reorder these. The options could potentially go into an editable config file for easier overview? Generally you settle on a particular configuration and touch it very seldomly.

With velocity bars there is more info displayed and the spacing is more uniform. The hyphen/minus as a spacer for natural notes helps to connect them; with spaces it is more confusing. Do you really use those low octaves so often @anonyme-x22? If it bothers you, a workaround is to transpose either on the SEQ or your synth.

Epic MIDIbox -- well done!

You can leave off the USB, it's only an additional +5V power option selectable by jumper..

One way is to use the punch in footswitch mode, but that's not exactly the same. Unless Peter knows of another way, maybe it could work to have scrub+footswitch (punch in) also delete notes under the cursor when the sequencer is not running? Also an idea is to allow an "off" footswitch setting, for example if you only have a mono footswitch.

For this, set up a note track on AOUT port channel 16 Note 16 DOUT drum gates/triggers Notes to CV Channel #16 (C-1, C#1, D-1, ... upwards) will be redirected to up to 64 digital outputs of the DOUT chain. Each key number triggers an individual gate for 1 mS, accordingly this mode is predestinated for drum triggers. The used shift registers have to be defined in the MBSEQ_HW.V4 file (DOUT_GATE_SR1..8)

MCP4922 was indeed developed for, so it could be a good start? It doesn't look like it has a serial output, so if you need more than 2 channels you need to run them in parallel with /CS lines. That is a good advantage of MAX525/MAX5500 or the TLV chip. The midiphy euroceiver has an IDC header that may be attached to a "crimpable" DB-25 connector. So that way it can sit in the back of the case if you like.

Great that you got it to work!

Seems like the bootloader is also corrupted, so the next step is to connect through ST-LINK and try to reflash that way. Please see here: http://ucapps.de/mios32_bootstrap_experts.html
