[net.music.synth] my experiences with MIDI

*** REPLACE THIS LINE WITH YOUR MESSAGE ***
I have been using a Sequential Circuits model 64 sequencer
with the Commodore 64 computer.  So far I am very unhappy
with the results.  MIDI, I feel, is a lot of hype right now.

My set up includes a DX-7 and an Oberheim DX drum machine
along with the sequencer.  I have never been able to
synchronize the Oberheim with the Model 64.  
Although I have received virtually no support from Sequential,
my opinion is that the model 64 does not read the 96 pulses
per quarter note from the DX correctly.

What I want is a sequence that loops so that the new beginning
is EXACTLY on the downbeat. So far - no dice.  Fun huh?
Actually it's a real pain.  I did not buy this stuff to figure
out all their problems.  Think I can get my money back?
Sure!

Moreover, it is *almost* impossible to create an overdub that
starts at the beginning of the master sequence.  Musically
useful - isn't it?  There's a trick you can use to do it - but
it wastes a sequence:  Hit the first note(s) a fraction after
the sequence starts and hold it for the correct length of time.
Then auto-correct the overdub to quarter notes and the software
will put it on the downbeat.  Gee - isn't that efficient?

Someone told me to try taking the metronome output from the DX
instead of the clock output.  The metronome output can be
programmed to provide 4/8/12/16/24/or32 pulses.  I tried them
all.  The 64 does something different - the beginning of the
sequence now starts a fraction too soon.  Furthermore, there
is no autocorrect now.  I can't figure that out.

I think the Model 64 hardware/software is off by one pulse!
This error accumulates through the sequence until there is
a noticable discrepancy in the timing.

Sequential claims that the DX in the only drum machine that
they're having problems with.  I really doubt it!

The potential for digital MIDI recording is vast.  All the
manufacturers say "Please, give us a break."  I would if
they didn't rush their products to market before they're
ready.
