Program Loading
Because of the large number of potential Programs in
the 960L, Program Change messages are used along
with the Bank Select extension to provide MIDI
Program selection. Controllers 0 and 32 are sent to the
system, followed by a Program Change message to
select a program. In this method, Controller 0 provides
the most-significant 7 bits of the Bank and Controller 32
provides the least-significant 7 bits. The Program within
a Bank is selected with a Program Change message.
Each Bank has 10 programs or less, so only Program
Changes 0 – 9 will cause a program load.
The Bank values are "sticky", that is, the 960L will
remember the Bank values for each MIDI channel. It is
not necessary to send a Bank change with each
Program Change unless the Bank has indeed changed.
This is in full conformance the MIDI specification.
Bank and Program Mapping
There are 10 Programs or fewer in each Bank. Bank
and Program Changes out of range will be ignored.
Card Configuration
The DSP card is partitioned through Program Change
messages on channel 1. The highest Bank number
(16383, 0x7f on Controller 0 and 0x7f on Controller 32)
is used for this purpose. Other Bank numbers are
reserved for future use. Here are the values:
Continuous Controllers
The 960L does not respond to continuous controllers,
except those used for Bank change.
