IMHO, to "accurately transmit" means that you have to be able to
schedule with an accuracy at a resolution of 1 MIDI byte (320usec).

I would prefer timestamping MIDI messages with some common clock.

Ok then :)

Nope, I meant a Michaelson interferrometer. This has a single

distance between the diaphragm and laser changes. So you are
actually measuring displacement to the accuracy of a
wavelength of light, and using a counting process (which i

It is always a good idea to archive the original digital recording,
and create cleaned version only for playing.

Debian started installing from the web even I specified that I don't
have network and want install from discs! I had to edit some file
in /etc in order to get the debian installed. Unfortunately, then I had
to do it manually.

What you are making in itself is an analog to digital
converter. Questions that pop off the top of my head:
1. different angles will have different lengths to the detectors, are you
thinking of making the detectors curve to the geometric shape?
2. Since the laser will not be a point but a spr

I'm seraching for a free of charge midi-specification. My main-interest
is in gm, but I'm also looking for gs and maybe xg. I only found the
specifications at the mma. Can anyone help me?

actuallyt you can get digital microponones: they measure the
displacement of the diaphram by counting fringes on a laser
interferometer, so there never is an analogue signal (except
the physical movement of the membrane itself).
