[sdiy] Atari latency, was:Camel*ont* soft Da synth!

[rude66]

i think the latency the atari is famous for, is not that kind of latency,
but the kind of a steady clock, playing all the notes tight, and keeping
everything clocked. more of a playback than a recording thing.

scott, an atari can handle quite a few midi tracks, controller info, sysex,
pitch bends.. as can my mmt8's. these are 20 year old machines, running on
16 mhz speed (atari) with a whopping 4 mb memory. if i can't reproduce these
tracks faithfully on a pc running 100 times faster with more than 100 times
more memory, there is surely something not right. if a pc can't handle a
bunch of aftertouch/sysex/ controller data..

2 years ago, i did a cover of an iron maiden track. some parts came from a
midi file of the track, that included the guitar solos. in the end, i had to
record those track by track into the mmt8, who played them flawlessly when
the pc choked on them big time.
and yes, i also use multiple midi ports, and then split the signal..
