emastyle Posted February 14, 2010 Report Share Posted February 14, 2010 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 Quote Link to comment Share on other sites More sharing options...

skunks Posted May 28, 2011 Report Share Posted May 28, 2011 I've also thought about the similar project. What do you think, using CORE_STM32, how long does it take to scan e.g. 120 keys? Will scan rate be sufficient to determine correct velocity? Quote Link to comment Share on other sites More sharing options...
skunks Posted March 28, 2017 Report Share Posted March 28, 2017 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.
