Connecting a Keyboard, Sequencer, and the 480L.
Applications
Using a MIDI Keyboard to Control the 480L
You can select 480L registers and control up to ten
parameters and/or events simultaneously using the
controllers and switches found on MIDI-equipped in-
struments. Nearly any MIDI-equipped keyboard or
synthesizer can be used to remotely select registers
on the 480L.
Remote Register Selection
1. Connect the 480L and the MIDI controller as shown
in Figure 10.1 or 10.2.
2. Enter the control mode and set slider 5 on page 5
(PGM CHANGE MODE) to FIXED.
3. Exit the control mode.
Select some presets on the synthesizer. The 480L
should select and load a different register each time
you select a preset on the synthesizer. MIDI program
changes from 0 to 49 will load the 480L internal
registers (0.0 to 4.9). MIDI program changes from 50 to
99 will load 480L cartridge registers (5.0 to 9.9)
Note: Some synthesizers and controllers start num-
bering their presets at one instead of zero. Selecting
preset 1 sends MIDI program change 0. A
synthesizers organize their presets into banks of eight,

numbered from 1.1 to 1.8, 2.1 to 2.8, and so forth. If you
experiment a bit, the relationship between the MIDI
controllers preset numbers and the MIDI program
changes it actually sends will become clear.
Using Corresponding Registers
You will quickly discover that a fixed relationship be-
tween MIDI program changes and the 480L register
numbers is not very convenient. Changing the presets
in a synth, or the register contents in the 480L is not
easy, since you have to arrange everything so that
MIDI program changes have the desired effect.
To solve this problem, the 480L has a corresponding
register table which lets you assign any register or
program to any MIDI program change number. Dealing
with MIDI program changes becomes much easier,
since you can completely rearrange the relationship of
MIDI program change numbers to 480L registers and
programs in minutes.
The corresponding register table also lets you make
more economical use of registers, since several MIDI
program change numbers can be assigned to a single
480L register. Finally, it allows you to load any of the
preset programs with MIDI program changes--some-
thing which is not possible in the fixed mode.
