Midibox CV Trigger Outs

Design Concepts
1

I have a very quick question – on the WIKI there are instructions and code for adding additional DOUT triggers to the Midibox CV.  Currently the code works with midi channel 1.  Can anyone help me identify which parts of the code reference the midi channel?  I’d like to change it to reference midi channel 16 instead.

Code reposted below for convenience:

USER_MPROC_NotifyReceivedEvent

	;; BEGIN --- control DOUT pins via Note events at channel #1
	movf	MIOS_PARAMETER1, W ; Note Off -> Note On with velocity 0
	andlw	0xf0
	xorlw	0x80
	bnz	USER_MPROC_NRE_NoNoteOff
USER_MPROC_NRE_NoteOff
	bsf	MIOS_PARAMETER1, 4
	clrf	MIOS_PARAMETER3
USER_MPROC_NRE_NoNoteOff

	movlw	0x90 ; check for Note On at channel #1
	IFNEQ	MIOS_PARAMETER1, ACCESS, rgoto USER_MPROC_NRE_NoNoteChn1
USER_MPROC_NRE_NoteChn1
	;; MIOS_DOUT_PinSet expects pin number in WREG, value in MIOS_PARAMETER1
	movf	MIOS_PARAMETER3, W ; velocity == 0: off, velocity != 0: on
	skpz
	movlw	0x01
	movwf	MIOS_PARAMETER1

	movf	MIOS_PARAMETER2, W ; pin number: note number - 0x24, we start with C-2
	addlw	-0x24
	andlw	0x7f
	call	MIOS_DOUT_PinSet
USER_MPROC_NRE_NoNoteChn1	
	;; END --- control DOUT pins via Note events at channel #1

	;; process MIDI event
	call	CV_MIDI_NotifyReceivedEvent

	;; for best latency: branch to USER_Tick so that the new CV values
	;; will be mapped immediately
	rgoto	USER_Tick

Don’t forget the GROT :wink:
