touchy
I wanted a way to visualize musical intervals within chords, in a layout that's not biased to a particular key (like a a piano style keyboard is).
This
- allows varied layout. So far I've played with
- a few octaves of chromatic (see screenshot)
- guitar and uke layout
- isometric with thirds and fifths
- optionally mentions
- note name (disabled in screenshot below)
- Intervals to all touched notes
- colors by consonance (blue) or dissonance (red)
- reacts to multitouch
- reacts to MIDI input
- plays to MIDI
This is code leveraging the Kivy framework, because it's a very convenient way to quickly make this sort of experiment - the first functional version was under 100 lines.
Requirements
TODO
-
change button behaviour
- right now reacts twice
- figure out whether/why changing button text makes it so slow to respond to lots of touches at once (is it relayouting?)
-
actually add the code here
-
figure out other realtimeish issues
-
think more about the consonance/dissonance coloring
-
packaging so I can offer download rather than 'please install these things'
CONSIDER
-
make it react to sliding touch
- as in, hit all buttons you pass, not just the one you land the touch on
- consider strumming, pitch bends
-
add on-screen config, e.g. swapping to other layouts, what to show on buttons, switching midi channel
-
add file config (e.g. for what MIDI device name to prefer)
-
think about other musical concents I want to explore with this
- make it smart about chords?
