Analog clock signal from AOUT_LC

MIDIbox SID
1

I need to have my Midibox SID sending an analog clock signal (GND to +V square) to have the arpeggios and patterns sync with my analog gear.

Is that possible with the AOUT_LC module? or is that module just for filter COF and reso?

I’m sure you could use an AOUT but it’s probably easier to use a pin on the PIC…

SID_WT_Branch_Play
	;; send MIDI clock if enabled for synchronization of external sequencers or similar
	movlw	0xf8
	BIFSET	SID_MIDI_SYNC, SID_MIDI_SYNC_SEND_CLK, BANKED, call MIOS_MIDI_TxBufferPut
	SET_BSR	SID_BASE

Only place I could find it sending MIDI Clock… I’m sure that can’t be right. Wilba will chime in and correct me any minute I’m sure :wink: Anyway, you just need to insert the lines to set and clear the pin. Are we talking about sync24?

PS An amusing conversation that just happened here:

ME: <typing away furiously>

GF: What you doing, honey?

ME: Uhm… Just helping out with some SID programming thingy for this guy <points at the screen>

GF: Oh… Writing love letters to Wilba huh. :stuck_out_tongue:

::slight_smile: Smartarse! LMAO

I don’t think so, what I need is a clean analog clock signal (1-bit, 12 V). One pulse per step. (not 6 or whatever midiclock uses… :P)

That’s probably more commonly known as a trigger signal than a clock… The CV/Gate Out on the AOUT might be bang on? I’ll leave this to the analog gurus around here I think…

I would still say clock-signal… but anyway…  :stuck_out_tongue: Do I have to program a lot to achieve this?
