Hi, This does not belong directly to the MIOS, but I haven’t found a better sub-forum for my question… I’m trying to learn a lot of the low level stuff associated with MIDI right now. Mostly about USB connection.… --- ## [Who knows how to implement a USB Stack for PIC microcontroller?](https://forum.midibox.org/t/who-knows-how-to-implement-a-usb-stack-for-pic-microcontroller/20437)

Last week I have dug up one of my older projects: for a long time I wanted to create large capacitive touch pad that only uses PCB layout as touch-sensitive components. I chose a PIC24FJ128 because it comes with 50 ADC… --- ## [SEQ4 and OSC (Midi usb router)](https://forum.midibox.org/t/seq4-and-osc-midi-usb-router/19995)

Hi All, I hope this is considered the correct part of the forum for this. I am a novice midi to MIDI and a general tinkerer. Not much of a musician either… I saw the Goom Synth build on the STM32F4 and thought it looke… --- ## [USB to MIDI converter?](https://forum.midibox.org/t/usb-to-midi-converter/19310)
