| + | __Define the number of connected DOUT shift registers:__ | ||
| + | |||
| + | If you're using more than one DOUT shift register, you must also change this code in "main.inc" to reflect the number of shift registers: | ||
| + | <code> | ||
| + | ;; initialize the SRIO driver | ||
| + | movlw 0x01 | ||
| + | call MIOS_SRIO_NumberSet | ||
| + | </code> | ||
| + | To set it to the maximum (16), just replace the code with this: | ||
| + | <code> | ||
| + | ;; initialize the SRIO driver | ||
| + | movlw 0x0F | ||

| - | //(Could this code be used to add 32 trigger outs to the MIDIBox SEQ? Separate question, would it be possible to code for S-Trig - having the DOUT pins held normally high, and drop to 0v on NoteOn? - Bunsen)// | + | MIDIbox SEQ allows up to 48 digital outputs as this type of trigger.

| + | __Changing the midi channel:__ | ||
| + | |||
| + | If you want the DOUT triggers to respond to MIDI events on a channel other than #1, replace instances of "0x80" and "0x90" with the following values: | ||
| + | |||
| + | * Channel 1: 0x80, 0x90 | ||
| + | * Channel 2: 0x81, 0x91 | ||
| + | * Channel 3: 0x82, 0x92 | ||

| - | I've considered the routing to up to 128 ports in MBSEQ V3. A port is either the internal EUSART based MIDI output, one or more external MBHP_IIC_MIDI modules, or analog/digital outputs. Routing examples will be available in the source code, the new possibilities are endless! | + | |
