CCOS documentation describes an arpeggiate as “A quick, single key press and release used to indicate a suffix, prefix, or modifier to be associated with a chord”
I’m focusing on the “prefix” part. I haven’t heard much talk about it so I assume it isn’t a current feature in CCOS.
This would be a really interesting addition, and I assume would work like the capitalization modifier where you can delete the whole word and add it back with a different first letter (capitalized). With a prefix modifier you could add “un”, “pre”, “semi” prefixes to the beginning of chords.
I’m using this suggestions channel as a feature request, hope that works! 😀
