HyperTalk scripted notation
using QuickTime Musical Instruments.

It includes the application and the Read Me file.

One way is from the command line:

PlayCmdAgent quit
PlayCmdAgent play musicbox 100 eq cq eq qr eq cq
PlayCmdAgent playstr musicbox eq cq eq qr eq cq
eq tempo 100
PlayCmdAgent playnote musicbox 60 127

The syntax is:

PlayCmdAgent quit
PlayCmdAgent play <instrument> <tempo> <notes>
PlayCmdAgent playstr <string>
PlayCmdAgent playnote <instrument> <pitch>

The other way is to write one of these commands
to a text file in
C:\WINDOWS\ called PLAYCMD.EVT. As soon as the
file is readable and
nonempty, the command will be picked up and the
file will be deleted

BIf you have any questions, please send them to


Instrument = name|number.
Pitch: middle C = 60
Velocity = volume, from 1 to 127.

To stop a note started with playnote,
call playnote again with the same instrument
and pitch but a velocity of 0.
For best results, use only single spaces 
between parameters.


so we are still dependent on Quicktime,
so be it.

the Velocity (Volume) parameter does not exist
in HyperTalk, that's a QT specific activation?
