Alpha Systems, Dataton, AMX, Opto-22, and a zillion others make digital
output
cards that are serially controlled.  Many are RS232, others are RS485 but
that
should be no problem with a mac (I'm pretty sure you can get both phases of
both rx and tx directly out the modem/printer ports - the apple Tech Info
Lib
has pintouts http://www.apple.com).  Use the serial object to set baud rate,
etc
and just come up with a little lookup/transmit and receive/parse code.

If you need contact info for any of the above companies drop me a line.

Also, for direct Note On MIDI control, PAVO Miditools might solve your
problem.
http://www.pavo.com or email greg@pavo.com.  They're kits but I think
they'll
assemble them too.

 This is documented under the various output objects. These objects
(noteout, ctlout, etc.) take a MIDI channel number as an argument. They can
take a letter argument to set the port if you have more than one. There is
also an inlet to change the channel number.

This inlet can be used to make a patch flexible (i.e. controlling ch1 or 7
accordnig to the user's desires) but should not be used for polyphony. In
other words, don't send a [60 92 2] to start a note on  channel 2, then a
[66 84 3] to the same object to start another note on channel 3. Use two
noteout objects instead. In all but the simplest of patches, the former
approach leads to hung notes. With a noteout per channel, your patch will
be cleaner, and you can use  flush objects to catch any leftovers.

**plug coming**
Of course you can use the channel inlet if you are generating your notes
with Lnote, a multichannel makenote type object that is part of the
Lobjects. The Lobjects are distributed with 3.5, and can be found at the
address below (click on Research and read down a bit).

Incidently, Lnote was flawed in its first (limited ) distribution. It's
fixed now. Effusive Thanks to those who sent bug reports to me about the
Lobjects. Your comments allowed me to spiff them up for the CD and
prevented much embarrassment.

Does MAX 3.5 require OMS 2.x, or could I still use 1.2.3?

How is RAM usage compared to 3.0?

Hmm. I bought MAX back in 1991, but from Opcode directly because the UK
dealer had never heard of it. I'm pretty sure it was the same dealer as it
is now. Your description of their behaviour would suggest so.

Vision bulletproof? Not in my experience.

I agree.

Try changing values in the tempo track while running.

In fact, the chases in Vision are terminally broken...
they sometimes don't work, often kill sustained notes...
