Indirect Map Addressing:

This is the function of controller #32 when set to 0. Map 0 does not actually exist. Map 0 is any

Map you want it to be. Place a different map value into Tone Map 0 at 40 4X 01 and the part

so affected will use that map when map 0 is asked for. Its a neat little tinker, but what it is really

useful for is causing trouble.

Since every map is always fully directly addressable why do this? The only useful purpose I can

think for using it is to repeat a GM sequence several times, changing what map it uses each time

without changing the sequence.

Direct Map Addressing:

This is what you do every time you call a patch when controller #32 has a non-zero value. This

form of addressing a map is stable. It will never change. Files that address maps this way will

work on every Sound Canvas that plays them so long as they have the maps available.

Theoretically we can go through 127 generations of Sound Canvas before controller #32 has

reached its potential.

The purpose of direct addressing is upward compatibility.

Understanding Map 0:

As we said above, the 3rd obstacle to upward compatibility is the misuse of bank 0. Do not use

bank 0 for native map sounds unless you need them during the development phase. After

development, change all patches to use direct addressing. The truth is Map 0 does not exist.

Map 0 is only a place for the Sound Canvas to send you to another map. Think of it as a Go To

Jail map.

Each of the three generations of Sound Canvases respond to sequences with map 0 patches in a

unique manner. Three different sonic results are unavoidable with patches that reference map 0

sounds.

The way Roland engineers designed the series of Sound Canvases, they all use map 0. Even the

SC-55 uses map 0. Well -- sort of. No matter how you accomplish the switching of maps,

variations or banks or whatever you end up calling them, the native sounds on the SC-55 are

located internally on the SC-55 by a process effectively identical to map 0 addressing. In fact all

128 possible controller #32 maps are interpreted by the SC-55 as if they were the SC-55 map.

However, once you move up to the 2nd generation or higher, the SC-55 map is logically set up

as map 1. So compatibility says, “Hey why not always use map 1 on every Sound Canvas to

get SC-55 sounds.” We can even use map 1 on the SC-55.

You might object, “But the SC-55 does not really have a map 1.” I say whisper quietly because

the SC-55 does not know it does not have a map 1. You get to map 1 through controller #32.

The SC-55 ignores controller #32. So if you try to go to map 1 on the SC-55 you go nowhere.

You just stay right where you are. And that is where you want to be, using SC-55 sounds on

map 1 just like ALL the other Sound Canvases do.
