Chapter One, Basics Sound Sets

The Sound Canvas Family:

The Roland Sound Canvas is an excellent sound module family that can meet the needs of both

beginners and experts. The family is characterized by a similar structure for mapping what

Roland calls GS Variation Sounds built upon the foundation of a GM compatible sound set.

All Sound Canvases use at least a minimal Roland GS specification with the exception of the

SC-7, SCB-7, RAP-10, and SCD-10 which were intended for the personal computer market

as sound cards or daughter boards. The most common GS sound sets are often referred to as

SC-55 Sounds, SC-88 Sounds, and SC-88 Pro Sounds.

These sound sets are characterized by 128 Capital Tones representing their GM compatible

sound set but with variations to these Capital Tones available on additional banks. For example,

the GM sound set includes only two synth bass sounds at patches 39 and 40. But the SC-55

added 4 additional synth basses by placing 2 each on variation banks of the two original GM

patches.

The general rule followed by Roland with these additional variants to the GM sounds was to

place them at the same patch number as the GM sound but on a different bank. This made

locating and using variant sounds easier.

What follows is a brief history of the various generations of Sound Canvases combined with a

brief history of how the mapping compatibility issue got so confused. For an up to date list of all

the GS synths, point your browser to the Sound Canvas List maintained by Gary Agnew

The SC-55 Family:

The 1st generation Sound Canvas was the SC-55 which had 317 sounds, 10 drum sets, and 24

notes of polyphony using up to 16 voices. One of the drum sets was actually a sound effects

menu in a drum map. Later the SC-55 sound set was expanded to include 354 sounds and its

polyphony was increased to 28 notes.

These 354 sounds also included the MT-32 sound set. And for compatibility with pre GM

Roland synths, a CM-32L sound set was also available. However, all of the sounds of the

CM-32L (sometimes called CM-64) are duplicated in the SC-55 Capital Tones or Variation

sounds so this does not represent any additional sounds for the SC-55.

To select Variation sounds, the SC-55 can use both “Normal” and “controller #0” methods of

bank switching. The controller #0 method is easiest because all that is required by your
