  1. 12.8 mS sounds a bit slow, but I'll test it out. I assume DIN is a lot faster. Is it easy to change the MBNG firmware for an experienced programmer or are there really fundamental limitations? Can you send me instructions to update my old PIC 18F452 to the latest MIOS version? The current bootloader was loaded 9 years ago and doesn't work with the new MIOS.
  2. Could you not solve your issue by making an adapter that first in your keyboard and that you can mount on an 5V line of the Midibox? Do check the requirements on Current though.
  3. I've started a midification project of organ manuals to hook up to organ simulation software (Hauptwerk). As interface I'd like to use a reflective opto switch. I'm currently testing this with the Vishay CNY70. When pressing a key, the amount of refective light and thus the output resistivity / voltage changes. To scan the output I have two options: 1) Scan it with DIN and tune the correct voltage for the moment it switches, perhaps with some potmeters to tune the LED or output voltage. 2) Use AIN to scan the acual position of the key and set a threshold for each key on when to switch. This enables full control over the key, and for example enables a different position of NOTE ON and NOTE OFF. I'm wondering however if this would response fast enough to play music. I still have some old parts (MIOS V2 mainboard) for testing, but could also get a newer version.
