2263.0. "Autolocate\SMPTE\Midi Q's" by LUDWIG::RAPHAELSON () Fri Feb 16 1990 09:32
I just bought a Fostex 4050 Autolocator to use with my B-16D recorder.
The owner's manual is awful. The unit has all the standard remote
control transport functions, record enable/disable for 16 tracks,
an LED readout for actual tape time, section time, and SMPTE frame,
and memory for 10 point autolocate, auto punch-in, rehearsal looping,
etc. The real reason I bought it, is because it also has a built in
SMPTE generator and reader, as well as SMPTE to Midi conversion
with song pointers, and Midi in and out. So now I can start to
lock-sync the synths and the tape deck and eventually my IBM AT
clone PC. Swell. Now, to the interesting issue: The Autolocator
has an RS-232 port built in, using a din type jack. There is no
info in the manual about it, and when I called Fostex, they said
they never developed any software for it, and no one new anything
more about it. Any conjecture as to whether any 3rd party software
might make use of this? What for? I suppose it could just be used
for additional memory to store more autolocate points or punch-in/outs.
Maybe it could be used to aid in final mixes by programming the
source/record enable switches in place of channel on/off switches
on the mixer- in effect, programmable noise gates, if nothing is
connected to the recorder channel inputs. I don't suppose there
might be access to the SMPTE/Midi stuff through the rs232 would
there. Is it possible to use serial communications from a sequencer
on the PC to direct the SMPTE/Midi on the Autolocator without using
a midi conversion card on the PC? The Autolocator even has a built
in metronome wih audio output and an LED, and a way to regulate
tempos in selected areas by defining quarter note values. It's
supposed to be great when linked to my Roland 707 drum machine.
That should help precise timing for soundtrack type projects. One
other question - of the four SMPTE formats available on the machine,
which should be used for projects whose ultimate use/future has
yet to be determined? The formats are 30 FPS, 24 FPS, 29.95(?)
drop frame FPS, and off hand, I forget the fourth. At any rate,
a potentially fun machine with lots of interesting applications.
Any wild ideas or answers to questions posed will be appreciated.

From my limited knowledge of SMPTE, I would guess that 30 fps is the
most common. (Of the boxes that only offer one type, this is the type
frequently offered.) I think 24 fps is the speed of motion picture
projectors. I can't recall the specific reasons why each format exists
but there have been some articles in Music Technology and/or Home &
Studio Recording in the past year about it.
I use 30 fps because it's all the JLCooper PPS-1 lets me have.
Hope this helps.
