I've been working on overhauling some of the existing documents out there in a way that makes more sense to me.
There's currently 3 sheets:
the first contains tick counts for every Speed/Length combination (assuming 6 ticks per step) and highlights which of these correlate to whole, half, quarter, eighth and sixteenth notes. Also contains which frames are included with each length (thanks danimal cannon!)
the second is a list of scales... someone else had started one but it didn't include what steps in hex the correlated to. I'm still adding more scales to this.
third is a list of quick reference of chords in major and minor for arpeggio help
I have more to add to this, including which divisions result in which intervals for ghost channel. This is mostly for personal reference and to make music theory concepts translate into hex easier.
Here's the link, let me know what you think.
