AOUT routing question.

MIDIbox SID
1

Greetings,

I finally got around to installing the latest SID OS, with ‘303’ control, and have been loving it.  I was hoping that the pitch of the sequence would be mapped to an output on the AOUT, and once again I need to dig into the source files to figure out the AOUT hard-coded routing.  I’m having a hell of a time finding where in the code this is laid out… there are something like 60 files to wade through.  Any idea which file/files define the AOUT routing?

I Finally got around to posting some pictures and details on my modular midibox SID here:

you’re after midi_evnt.inc, line 114 :slight_smile:

Okay, so I must be blind, but the midi_evnt.inc file wasn’t included with midibox SID v 1.7303, or earlier versions that I have either.  What am I missing?  ???

Heh sorry that was for the seq… I’ve got sequencers on the brain :wink:

Gimme a minute here…

I’m not so well versed on the MBSID but try sid_sw.inc, line 400…
