[PD] Gem Rutt-Etra / pix_data speed?

[Derek Holzer]

Very interesting!

However, what comes out is still limited by the block size to every 64 
samples as far as I can tell. I've tried every trick I can to send 
sample precise messages in, but all I ever get is 64 sample rate 
messages out.

Or am I missing something? See attached.
