I'm working on a program that uses the GS Sound Tools, Note Synthesizer, and
Note Sequencer. One part of the program moves waveforms in and out of
DOC memory by calling the Sound Tool routines (MoveToRam, MoveFromRam?).
The Toolbox Reference (Vol II) has a "Warning" that interrupts must be
turned off while accessing the DOC RAM. My questions...

   Which interrupts must be off? The Sequencer interrupts are off
   during the moves, but do others have to be off as well?

   How does one turn interrupts off and on from TML Pascal? Miscellaneous
   Toolset routine? Inline procedure to invoke machine code? Assembly
   language subroutines?

   What happens if the interrupts are not off during the data moves?

Thanks in advance!
