Hello, I'm looking informations to build a system for MIDI retrofitting my Fender Rhodes.

I'm planning to build a system like PNOSCAN (http://www.qrsmusic.com/storyclark-p.asp?pg=1&cid=51&pid=3394) by myself.

What do you think is possible this using the CORE_STM32 ?

This is the US patent where I think the system is based from http://www.patentstorm.us/patents/5567902.html

Bye

Now it's interesting to know, how fast can LPC module scans one (or two) fully stuffed AINSER64 ?

I've only found this info about old PIC based core: 12.8mS and more with Dynamic Priority handler ™ which scans the last two changed AIN pins more often than the others.

For the project described above Dynamic Priority handler ™ would be useful for ~10 last changed AINSER pins (if scan rate is more then 0.2uS-0.5uS) in order to determine note velocity more precisely and send polyphonic aftertouch.
