I've dowloaded your files - they look very useful, and nice and simple for a
single cv/gate output, but my cv convertor is processor based, and has 40 cv
outputs and 32 gate outputs.

What I want to do is just to cut out the serial midi interface from the PC
to my cv convertor.
I gave up using my PC for sequencing because the timing via my midi
interfaces was dreadful - probably down to latency in the soundcard etc.
more than just midi itself, but I found it unusable.
If I can use a midi driver in seq303, Cubase etc, that speaks to my cv
convertor processor directly, via the parallel interface, I may be able to
start using my PC for sequencing again. Also, my friends use a cv convertor
I built for them, and I had big problems getting two soundcard midi
interfaces to work on their PC (they use one interface just for cv'ed gear).
They would benefit from a parallel i/f to their convertor too.
My convertor already has a printer port compatible interface that just
expects to receive midi bytes directly - so it seems I just need to work out
how to write the midi bytes to the parallel port on the PC and off I go...
