deckerego / macropad_4chord_midi Goto Github PK

• Upgrade to latest version of CircuitPython
• Upgrade to latest version of Adafruit libraries
• Remove temporary constants from controls.py

Somehow support 7th chords (and optionally augmented & diminished chords) even tho we only have three keys per note

For example, what is being shown as "Oct: 2" or "C2" is actually being sent as C1 over the MIDI channel

When connected to an Android device the macropad halts at code.py output and will not boot all the way.

MusicRadar and John Mayer were right, I was wrong:

Verse: ii-V-I-IV-V
Chorus: I-iii-vi-IV
Bridge: iii-vii-iii-vii-ii-V

On maybe the 10th measure of a short melody in Hookpad, attempted to send a 7th chord to Hookpad as notes for the melody line. Rather than being recorded in octave order they were recorded randomly (a different sequence after repeated attempts).

No arpeggio delay was configured.

Add a setting for the MIDI channel (possibly set in the control menu)

Currently we only support the major (ionian) mode. We should support the other modes, possibly by rotating the "CHROMATIC_SCALE_NAMES" constant to instead be a "diatonic scale" that is a rotation of C D E F G A B. From https://hellomusictheory.com/learn/mixolydian-mode/:

See also https://guitardashboard.com/ as a good way to validate that the additional modes provide the correct progressions.

Properly show diminished chord numerals (e.g. vii°) in progressions.

Love the macropad code, but I have a rather infuriating issue - mine only runs for a few seconds!

I have updated the macropad to CircuitPython 8.0.5, and copied every file from the Macropad.4chord.MIDI.v2.3.0.zip onto the pad without issues, and it fires up perfectly. However after a couple of seconds I get the message:
(snake emoji)[email protected] Keyboard
KeyboardInterrupt:

then:

The M105 continues repeating indefinitely

The only differences between the contents of my Macropad and your zip file is the presence of a file called settings.toml in addition to the settings.py, plus a bootout.txt containing:

Adafruit CircuitPython 8.0.5 on 2023-03-31; Adafruit Macropad RP2040 with rp2040

boot.py output:

I am a total noob blindly following instructions with zero knowledge of code or what I'm doing, so apologies if this is an obvious thing that anyone with any clue should know how to resolve!

Many thanks :)

@jedgarpark just posted a great build to the Adafruit Learning System with Hexpad: MIT licensed code available at https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Hexpad/code.py

Aside from the very cool hex layout there are some interesting ideas around choosing modes and the layout of chord intervals - will be interesting to see if there's anything to learn.
