I made a list of the parts I needed through work, knowing an order was 
going out that week, but then the parts I wanted didn't get actually 
ordered from mouser for ages. And then just before xxxmas when I got the 
parts, my main computer with the dev environment I was using for the 
software blew up.

Anyway.... I have the RS422 driver and receiver ICs I need now, and the 
computer kind of working again.

Only problem now, is I have 2 gigs in the next 3 weeks..... and the 2nd 
one is looking like it might be pretty big, so need to be well rehearsed 
for it (and our laptop we use for gigs is also malfunctioning for audio 
right now.... waaaah!).

but I'm very sure I can get this device to work, when I have a chance. 
Next step is to make the serial port run at MIDI data rate of 31250 and 
after that, 250k synchronous.

I *should* be able to make it do this just with the standard windows 
serial port driver, as long as I have an app to send those baud rate 
commands to it. Otherwise I might have to take over standard serial port 
speeds...
:-)



anyway - please keep hassling me about this (maybe after the 15th feb) 
to make sure I get this done. I really want to dump samples with my emax 
too!!
