Q Is it possible to have four simultaneous voices?
A Yes, you can have four simultaneous voices.
Q What load do four voices place on the CPU of a 25MHz 68030 Mac?
A Four voices are not a problem for a 25MHz 68030 Macintosh. On a Macintosh LC,
we have measured approximately 30 percent CPU usage using 5 voices.
Q Does the load level depend on the number of instruments used simultaneously?
A Yes. The actual load depends on how many instruments are playing
simultaneously.
Q Can we build our own instruments? If so, is there a tool available
for this purpose?
A In QuickTime 2.0, there is no way to add user-
instrument
files. However, you can embed instruments into QuickTime movies. Future
releases will add Musical Instrument Extensions to your system folder.
Q Are the answers to all the above questions the same for the Windows
version of QuickTime as they are for the Mac version?
A On a Windows machine, the music in QuickTime movies plays through a sound card,
with MIDI hardware support, using the MIDIMAPPER driver, with very minimal CPU
load.
Q Are the instrument sounds the same on Windows?
A The sound of the instruments can vary with the sound card installed.
Q Are most PC sound cards supported?
A The music in your movies will play on any PC sound card that supports MIDI
playback under Windows.
