incorrect, it is an audio buffer , processed at 'audio rate'
the code is:
the & means it has access to the entire sync audio buffer
the reason it doesn't 'work' is much more mundane
vowel does not support sync'ing...because the braids eurorack modules does not support sync for vowel, only for some oscillators.
why is sync an sync inlet if its not used?
because the interface underlying braids api is the same for all oscillators, so the objects where basically created from one 'template', we didn't go thru every braids oscillator to see what was used, what was not.
so really we should go thru the oscillators and remove those that don't support sync.
(but i don't have time to do this, as it involves go thru all the braids source code, checking, and then testing it doesn't break anything )
