What is Reddit's opinion of ChordCalc?

From 3.5 billion Reddit comments

You might like 2014 my Android app, ChordCalc, which does this in real time as you play the notes and is free and open source under the GPL! It also always offers 12 recommendations for each chord, meaning no possible chord is really missed. I found it a little odd that playing C, E, G, Am7 wasn't recommended as a possibility... You can see how my algorithm makes these recommendations on its GitHub if you wanna fork it!

If you want to know all the possible chords C-E-G could be, or any other chord for that matter, my Android app ChordCalc may be of use: https://play.google.com/store/apps/details?id=com.jonlatane.composer

Just play the chord and it will offer 12 possibilities of what it is, ordered from most likely to least likely.

Yes! Some friends and I have been working on a probably-overproduced video, but I was fiddling and figured out how to screen record this way with Google Play Games and this just kind of happened on my first attempt so I went with it :) By the next update I'll try to have a tutorial video up where I explain all the features simply.

But basically... If you look at the video you can literally see all the things I'm pressing to do the things I'm doing. The main things to note, in chronological order:

• In the time when I'm just playing a bassline and not settling on a tempo, look up at the top right corner. I'm tapping that button and it's synchronizing the tempo with me, which is how the initial slower tempo is picked out.
• The Colorboard, the jittery thing in the center of the screen with the rock organ sound, is scrolled by device pitch (i.e., point up to play higher notes, down to play lower notes). It's jittery because my hands are jittery! (And also it scrolls across the full span of a piano, which is a lot given sensor sensitivity.)
  • Also, the sequencer is literally just 16 of those Colorboards that show their full span and don't rely on device pitch.
  • In the video, right when I start using the Colorboard (midway-ish), I play the same note at different dynamics. Touches closer to the top are louder, closer to the bottom are softer.
• You can scroll on the bottom keyboard by scrolling from the left/right edges of the screen. So it's easy to play notes without accidentally scrolling! I borrowed it from my previous music app, ChordCalc.
  • A really serendipitous consequence of this was that it's really easy to use the Keyboard for bass and Colorboard for treble, or vice versa!
• Green = tonic, Blue = major, Purple = minor, Red = dominant, Purple-Red = diminished, Blue-Green = augmented, Yellow = subdominant/basically VI/vi and ii/II
  • You can do instant jazz voicings just by playing Green/tonic on the Keyboard in the bass, and anything but Green on the Colorboard!
