«GUI to generate scale- and arpeggio-like fragments in Just Intonation» by jordanwhitede

on 20 Dec'20 09:03 in guijust intonation

I developed this to help me work on hearing and playing in just intonation. It's my first GUI so feedback is very welcome, but it works basically ok for what I want it to!

/*

Simple GUI to generate scale and arpeggio segments of an overtone row above a given fundamental. This is the first GUI I've programmed, so it's certainly not perfect: most notably, all the numbers have to be typed into the boxes before the pattern will run. Feel free to contact me if you have any questions or feedback!

For non-experienced users: click in row 9 where it says "click here" and press CTRL+ENTER. Start with low volume to be safe :)
