To play predefined musical instrument envelopes, you simply
specify the envelope number in the PLAY command (see PLAY)
you do not need to use the ENVELOPE command. The
ENVELOPE command is used only when you need to change the
envelope.

FAST
This command initiates 2MHz mode, causing VIC 40 column
screen to be turned off. All operations (except I/O) are speeded
up considerably. Graphics may be used, but will not be visible
until a SLOW command is issued.

FETCH #bytes, intsa, expsa, expb
where bytes = number of bytes to get from expansion
memory (0-65535)
intsa = starting address of host ram (0-65535)
expsa = starting address of expansion ram (0-65535)
expb = 64k expansion RAM bank number (0-15)
