 +__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
 + call MIOS_SRIO_NumberSet
 +</code>

-//(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. [[http://ucapps.de/midibox_seq_options.html]]

 +__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 
 +  * Channel 4: 0x83, 0x93 
 +  * Channel 5: 0x84, 0x94 
 +  * Channel 6: 0x85, 0x95 
 +  * Channel 7: 0x86, 0x96 
 +  * Channel 8: 0x87, 0x97 
 +  * Channel 9: 0x88, 0x98 
 +  * Channel 10: 0x89, 0x99 
 +  * Channel 11: 0x8A, 0x9A 
 +  * Channel 12: 0x8B, 0x9B 
 +  * Channel 13: 0x8C, 0x9C 
 +  * Channel 14: 0x8D, 0x9D 
 +  * Channel 15: 0x8E, 0x9E 
 +  * Channel 16: 0x8F, 0x9F

-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!+
