map you get. If you talk this over with other SCUG members who do not use a sequencer like

yours they, will get the impression you are not too swift. All their advice will never help and they

will misunderstand all your questions.

If your sequencer uses patch calls that immediately follow controller #0 and controller #32

settings then you may be already off and running with the solution. Yet, if I were to talk to you

about bank numbers like 1025 you would scratch your head wondering what I am talking

about.

Three obstacles to compatibility:

1. New features limit backward compatibility.

2. Change in bank switching methods.

3. Use of map 0.

Let’s accept obstacle 1 right at the start. There is no way to make use of sounds or features that

do not exist on earlier models without compromises or accommodations. These will require

some fending for ourselves, but if you get the forward compatibility obstacles cleared up then

you will also be able to figure out the best compromises.

Obstacles 2 and 3 are fully resolvable. Once they are resolved, your sequences will sound

identical on every Sound Canvas to what ever degree that is possible.

Obstacle 2, a change from controller #0 bank switching to Normal bank switching, may require

some explanation. Only 2nd generation and above Sound Canvases use Normal bank

switching. But the SC-55 can respond to it anyway in a manner fully compatible to the 2nd and

3rd generation Sound Canvas. Changing to Normal bank switching for many of you (but not all)

opens the door to compatibility.

We need to define bank switching. This can be a confusing issue because each sequencer uses

the terminology differently. Roland uses completely different terminology from standard MIDI

lingo preferring words like Variation and Map. There are also banks switching methods and

bank switching implementations which are identical in effect but different in how they are used.

What a mess!

Understanding Bank Switching:

Bank switching greatly enhances the number of sounds a sound module can offer. Without

banks, the limit is 128 sounds. Using a single controller to enhance bank switching enables 128

banks. Each bank can hold up to 128 sounds. This would allow 16,384 sounds. Using two

controllers to enhance bank switching enables 16,348 banks. If each bank held 128 sounds this

would allow 2,097,152 sounds!

There are no modules that hold over two million sounds. The idea is not necessarily to jam pack

as many sounds as possible into every bank. Instead this structure allows up to 2,097,152
