Program Lock, Pan Lock, Volume Lock
When the parameter locks are set to On, the three parameters they control do not respond to
their respective MIDI controller messages. In that case, you could change the Program, Pan, and
Volume settings from the front panel, but not via MIDI.
Program Change Formats
The K2661 can store more programs than the MIDI program change specification can handle
(MIDI lets you send program change numbers from 0 to 127 or 1 to 128 only). So we’ve designed
a system that makes program selection more flexible. This is true whether you’re selecting
programs from the K2661’s front panel, or via MIDI.
First of all, the K2661’s programs (and all of its objects) are numbered and grouped according to
a decimal system, that is, in multiples of ten. This is much easier to keep track of than the binary-
oriented groupings of many synths, which feature banks of 8, 16, or 64 programs.
Next, the K2661 gives you 999 program change numbers to work with. These are organized into
ten banks of 100 each (the memory banks). A program’s object ID is its program change number,
as discussed on page 5-2. This makes it easy to keep track of your programs. The K2661 can use
several different formats for interpreting program change commands. The value for the
ProgChgType parameter on the RECEIVE page determines which format is used, and the one
you should select depends on your MIDI system.
If you expect you’ll always change programs from your K2661’s front panel, you can finish this
paragraph and skip the next few sections. In this case, selecting programs is as simple as
entering the program change number (the program’s object ID) on the alphanumeric pad, and
pressing Enter. Even program numbers above the usual MIDI limit of 127 can be selected this
way.
Extended and Kurzweil Program Change Types
In the early days of MIDI, most instruments had small numbers of memory locations, usually
32, 64, or 128. As instruments began to have more memory locations, however, users ran against
the limitation of only 128 values for program changes in the MIDI spec. Because of this, Bank
Change Controller was added, allowing users to switch between banks of up to 128 programs
per bank.
Previous to the addition of the Bank Change Controller, Kurzweil had developed their own
method of switching banks by using two program changes, one to switch the bank, the second
to call up the program within the bank (as described below). The K2661 can respond to either
