Raspberry Pi Pico 4xN Midi Arcade Button Box

Here's the full setup as run at the July 9 2022 event - FuzzFest 2022

The MIDI box sent data to resolume on PC.  It listened for one  of 64 midi notes and switched the video output.

The controller build was delayed by weather and overcommitted project lead (concept, art, carpentry etc by Markus) but was completed on site for FuzzFest2022.

Rewiring up the buttons became a community build project.

Err um yes we meant for that hole to be there. Had to get USB out of box somehow.

And of course a couple LEDs got wired backwards and had to be redone

Latest update (and likely one to be used at event) modifed the 5x4 version.

The "code_MidiQT_bankSwitch.py" version drops back to 16 midi buttons, with the 5th (default address) board being used as a "bank switch" - it changes the midi notes associated with the midi buttons.  4 arrays are used to hold the Banks, and pressing one of the BankSwitches,  changes which bank is active.

This is  the arcadeQT with the colored buttons.  The leds in these are Digital IO and stay on to show  which bank is active.

The 5x4 array misses most short button presses. If you hold a button down, it sees it and lights up. But if you more quickly press and release, it never sees the actions.

Not sure why the response time is so bad/flaky.  We upped the i2c speed to 400khz so that shouldnt be a bottle neck - not that it would be.   For near term we are calling it a Feature, because the beast goes live at event in 1 week.

Today we wired up a total of 5 arcade button boards with 30mm buttons, and extended the code to support it as total of 20 midi buttons.  The new code is in code_QTMidi_5x4.py in the github archive.

Here's my blond assistant checking over the connections of the full 20 button setup.

Next up will be making one set of 4 buttons be built in bank switchers. Pressing one of these will switch to a different button-to-note mapping.

Then we got the weekend  to build the housing and hook it up to Resolume so it selects 64 video clips.
