sequencer is to enter a zero into controller #0 for Capital tones or the Variation number into

controller #0 to select a variant bank just before sending a patch call.

The “Normal” method of bank selection did not exist when the first SC-55’s hit the market.

Fortunately, MIDI compliant devices must ignore controller messages they do not use. As a

result SC-55’s do respond correctly to Normal bank switching even though that was not

considered in their design.

Normal bank switching uses both controller #0 and controller #32. Since the SC-55 ignores

controller #32, sequencers that use Normal bank switching can still access all the Capital Tones

and Variations on the SC-55 without any problems as long as the Controller #0 value they use

is correct.

Sequencers that use the Normal bank switching method however, “simplify” the process by

using a single number in the range of 0 .. 16,383. If you are an SC-55 user, this might be

confusing at first. You never had to enter numbers larger than 127 before to get variation

sounds.

In fact, most of you will discover that your sequencer won’t allow you to enter a number larger

than 127 in a bank field. Hopefully, chapter 3 will show you how to either use Normal bank

switching or how to emulate it so that all your sequences will sound the exact same way on

everyone else’s Sound Canvas.

You can tell if your Sound Canvas is actually a member of the SC-55 family by the number of

GS sounds available. If your manual features 317 or 354 total sounds, then regardless of what

model Sound Canvas you use, it is for all practical purposes internally an SC-55

The SC-88 Family:

The next generation Sound Canvas is called the Super Sound Canvas with the SC-88 sound

set. This 2nd generation Sound Canvas also includes the complete sound sets of the 1st

generation Sound Canvas. This means the SC-55, the MT-32 and the CM-32L sound sets are

all included.

This gives the Super Sound Canvas a total of 654 unique instruments and 24 drum kits. Not all

of the SC-88 sounds are new. Some of the SC-88 sounds are actually the SC-55 sounds

duplicated into the SC-88 map. So of the 417 sounds mapped into the SC-88 sound set, only

300 of them are actually new sounds.

With the release of the SC-88, the Sound Canvas is now up to 64 note polyphony and can use

two MIDI outs with up to 32 voices and 32 MIDI channels. The SC-88 is also capable of

being split into two independent modules. This permits a GS-Reset on only one side and other

independent operations.

With the SC-88 sound set, Roland decided to add new sounds by accommodating the Normal

bank switching protocol, which in addition to controller #0 uses controller #32. They also

decided to use the value of controller #32 (the LSB of Normal bank switching) to select what
