By using the MIDI Machine Control, you can have sound effects stored on a machine
using magnetic tape or other media and have them played back when required.
In order for the tape machine to be able to locate the sound effect, you have to spec-
ify where to look on the tape. You do this by telling the tape machine how long it has
to play to reach that part of the tape that carries the sound effect. The playing time is
measured in hours, minutes, seconds, frames and sub-frames. A frame is equal to 1/
25 of a second
3
and a sub-frame is 1/100 of a frame.
To locate a sound effect on the tape, you use the command Locate. Other com-
mands available are:
■ ■ ■ ■ Play
■ ■ ■ ■ Stop
■ ■ ■ ■ Rewind
■ ■ ■ ■ Fast Forward
In the case where you use more than one tape machine, you have to give each of
them a specific ID. The default value is 0 and the ID you assign to the machine is
usually dependent on whether the machine has been pre-programmed by the manu-
facturer for a certain value or can be programmed by the user.
Before you enter data for MIDI Machine Control, you have to specify the frame rate 4 ,
(see fig 8-13 below). To enter data for MIDI Machine Control, double-click on the
entry boxes required.
3. Or 1/24th or 1/30th depending on the FPS standard.
FIG 8-12. The MIDI machine control window.
4. This is only necessary if your machine is sensitive to frame numbers outside of the range for
its set standard. Most machines will sensibly locate to the nearest “legal” frame.
