I’m new here and thought I’d finally come out with a post about a Active Sensing (AS) issue I am having with a STM32F4 DSP project I’ve been working on.
My project has MIDI via UART.
It works great with just about anything you throw at it… notes On and Off and CC msgs all get captured and interpreted correctly using a non AS keyboard.
BUT, when I try to use older M Audio or Yamaha Keyboards DIRECTLY, I get garbage up MIDI with hanging notes or a lowest note 0x00 or combination of.
YET, when I send the AS MIDI from those same keyboards into a USB midi interface and THRU that stream in a app like midi ox so it gets sent back out the usb midi out, my STM32 handles it just fine!
I can share some code later when I get home.
Just wondered if this issue rings any bells out there.
I have my code reject AS… think it is 0xFE… it’s supposed to ignore it and go back to fetch the next incoming byte…
Thanks in advance,
