compatibility is limited but forward compatibility is perfect. Now that you have a picture of how

maps work we can now ask, “How can we tell the spreadsheet to use a specific page?”

Each of the 32 parts in your SC-88 or higher can address maps independently. The specific

map a particular part is using can be manipulated or understood in several ways. You can talk

about modes, controller #32, SYSEX, indirect map addressing or direct map addressing.

Modes:

The SC-55 Mode and the SC-88 Mode are modes that temporarily mask map addressing in

the Sound Canvas. SC-55 mode basically operates by temporarily redirecting every map to

map 1. If your SC-88 Pro will accept a number larger than 3 (most won’t) at the Tone Map 0

address 40 4X 01, then it will go silent. But press the SC-55 mode button and suddenly you are

listening to an SC-55 sound which has masked the value of Tone Map 0 with a 1.

The SC-88 mode is a mode available only on the SC-88 Pro. In this mode all sounds from map

0 and map 2 are masked and sent to map 2. Sounds directed to map 1 remain directed to map

1. Sounds directed to map 3 not found on the SC-88 map go silent. Once the SC-55 Mode

and the SC-88 Mode are stopped, all maps return to their previous state even if the previous

state was not the default state. Direct map addressing does not bypass the mode switch on

most Sound Canvases. Modes affect all parts.

The purpose for using modes is to hear what your composition will sound like on an earlier

model.

Controller #32:

Whatever the current value of controller #32 is on any part, will be the map used at the next

patch call for that part. Unlike Modes which take effect immediately on all parts, a change in

controller #32 affects only one part at a time and does not take effect until a patch call occurs

on that part. The value of controller #32 is kept in memory at address 40 4X 00. The only

exception is when controller #32 has a value of 0. When that happens then the value stored at

Tone Map 0, 40 4X 01 will override its setting.

The purpose of controller #32 is to extend options for bank switching. When combined with

controller #0 the options are greatly extended.

SYSEX:

Using SYSEX to place a new value into Tone Map 0 at 40 4X 01 will give controller #32 a

new meaning but only when controller #32’s value is 0. If this address is set to 1 then controller

#32 events that are equal to 0 will use the SC-55 map on the next patch call. You can do this to

your own unit, but it is not a good idea to do this to someone else’s unit because a GS-reset will

not undo this tinker. Direct map addressing does bypasses the SYSEX tinker completely.

One purpose of this SYSEX is that it can alter the default map used after a GM-reset. Unlike

modes which affect all controller #32 values, the SYSEX affects parts only when controller #32

=0.
