Any attendees: please let us know whether System 8 has any chance of
supporting MIDI for professional applications. We all know how much of a
priority this is for Apple.

Hi Pavel,

I don't know about the cards you mentioned or Max's relation to them.

The problem is not so much that the serial port itself is busy, since the
rate is only 9600 baud. In fact, if you are only receiving frame numbers,
then the Sony's are not hard to deal with. You just send the framerequest
code (I think it is 0x60 or 96 in decimal), and you will get 5 ASCII
numbers back. This would be similar for a Pioneer if I am not mistaken.

The problem is that once you start sending more commands, the need for
ACK/NACK's complicates everything, since you must wait for each ACK
before sending the next byte. This in itself is not impossible in MAX
unless you are trying to send a lot of commands and keep them very
tightly scheduled. If you are only searching for a frame, playing and
monitoring the frame numbers, you should be able to deal with two Sony
LDP's on a 8600 without much difficulty. The problems I have run into are
where we were trying to control multiple players doing very tight quick
loops under very demanding interactive control.

I put together a patch that communicates to an LDP-1550 through MAX
serial object that seemed to work. If you are interested I will dig it up
and send it along.

Subject: max price

I've had it with trying to deal with the opcode web page.  Like most big
companies they make information hard to get ahold of, for instance,
requiring your complete address on the inquiry form, and not listing basic
information like price and
hardware requirements, only marketing fluff.  They're still thinking in the
age of print media (don't list things that are liable to need updating and
reprinting), and don't get how the internet can and should be used (give
good information because it can be easily updated on a daily basis, if

So, all I'm trying to find out is, what is the street selling price of Max?
