Since your development is not mios based, what hardware is required to run the Java, a core running mios128, plus DINs and DOUTS? Can this additional core be daisy chained with encoders for keyboards, pedal, pistons, etc.
If anyone is interested, I threw together a little java app today that will handle SAMs from jOrgan. It’s not MIOS-based of course, but it should do the trick until a better solution is found. It’s set up to handle 64 SAMs on channel 10 (0-based); 0-63 are the ON magnets, and 64-127 are the off magnets.
Here’s an example:
Stop #1
Activated: 155 0 127
Deactivated: 155 0 0
Stop #2
Activated 155 1 127
Deactivated 155 1 0
Stop #3
etc…
When Stop #1 is Activated, the app receives 155 0 127 (note 0 on, channel 10). The app then outputs 155 0 127, waits 333ms, then outputs 155 0 0.
When Stop #1 is Deactivated, the app receives 155 0 0 (note 0 off, channel 10). The app then outputs 155 63 127, waits 333ms, then outputs 155 63 0.
If anyone ends up building this from source, you’ll have to change the two device name strings to the names of your input and output devices. Also you can change the delay time to fit your SAMs. I’m using a slightly longer time, because I’m using the original electro-pneumatic combination action. Eventually I’ll make a GUI for this.
