places into which potential sounds can be placed. And this means the ability to organize a more

modest number of sounds into a meaningful logical structure.

Two methods for bank switching used by the Sound Canvas:

1. Controller #0

2. Normal

By the time we are dealing with 2,097,512 potential places for a sound to be placed, things can

get confusing. Every one using different terminology to divvy up the turf only adds to the

confusion. So lets define how we will use these terms and also mention some of their substitutes

or near substitutes.

Bank Switching Method: This is a protocol for enabling a MIDI device to locate different

banks so that standard patch numbers can find additional sounds. All bank switching protocols

have exactly three parameters. These parameters might appear in any order in your sequencer,

but include a bank number, a bank method, and a patch number. If your sequencer does not

use “methods” then you use controllers.

NOTE: Some sequencers do bank switching for you. Other sequencers make you do the bank

switching for yourself. Some sequencers allow you to do it either way. If your sequencer does

not use methods then what I just said might not make any sense to you.

A sequencer that does bank switching for you will give you a place to enter each of the three

parameters. You will have one place for a bank number, one place for a bank switching

method, and one more place for a patch number. You might have other fields related to the

track or source but they are not directly related to the bank switching protocol. These

sequencers never show you values identified as controller #0 or as controller #32.

If you are an SC-55 user who uses the sequencer method of “Controller #0 bank switching”

(Please notice I did not say if you use controller #0 to do bank switching), then you may have

noticed that the bank number and the required value of controller #0 are the same. Do not let

this confuse you. The bank number is not a controller #0 number. It is a number used to

calculate the value of controller #0. They are not the same number, one determines the other.

They only end up with the same value.

This might be especially confusing to SC-55 users. Perhaps this will help. If you have to enter

a controller #0 event to get sounds, then you do not use your sequencer’s bank switching

method to do bank switching for you. You do it for yourself. You are not using the method

called “Controller #0 bank switching.” You are using controller #0 to do your own bank

switching.

If your sequencer does not do bank switching for you using a method, then it will have some

provision for letting you do the bank switching yourself. It will allow you to enter controller

values directly into controller events and also allow you to follow those controller events with

a separate patch call.
