# Roland Sound Canvas

The Roland Sound Canvas (Japanese: ローランド・サウンド・キャンバス, Hepburn: Rōrando Saundo Kyanbasu) lineup is a series of General MIDI (GM) based pulse-code modulation (PCM) sound modules and sound cards, primarily intended for computer music usage, created by Japanese manufacturer Roland Corporation. Some models include a serial or USB connection to a personal computer.

## Products
### Sound Canvas

The first Sound Canvas units (SC-55 and SB-55) were sold in the winter of 1991, in some cases also sold as "Edirol" rather than "Roland" as the brand name, mainly with the SC-88VL.
| Model | Year | Standards | Parts | Voices | Tones | Drumsets | Output resolution | Notes | References |
| Roland SC-55 | 1991 | GM GS | 16 | 24 | 317 | 9 | 16-bit @ 32 kHz | Half Rack unit, first product of the line, units without GM logo and with firmware <v1.20 technically not GM compatible (GM reset interpreted as GS reset, capital tone arrangement not fully consistent with GM spec, Patch #122 is "Fl. Key Click" instead of "Breath Noise"). | |
| Roland SB-55 (Sound Brush) | 1991 | | | | | | | Half Rack unit. Floppy disk-based MIDI file player that was bundled with a remote control (Also works on the SC-55, 155, and 55mkII). Supports SMF types 0 & 1. A blank disk can be inserted for recording purposes, but only records in type 0 (A whole performance merged into one track). Playback starts automatically when a disk is inserted. | |
| Roland SC-7 | 1992 | GM | 16 | 28 | 128 | 6 | 16-bit @ 32 kHz | No display, introduced serial port for PC/Mac connectivity. | |
| Roland SC-33 | 1992 | GM GS | 16 | 28 | 226 | 8 | 16-bit @ 32 kHz | Table top version of SC-50, rebranded as BOSS Dr. Synth DS-330 (fewer tones). | |
| Roland SC-155 | 1992 | GM GS | 16 | 24 | 317 | 9 | 16-bit @ 32 kHz | Table top version of SC-55. | |
| Roland SC-55mkII | 1993 | GM GS | 16 | 28 | 354 | 9 | 18-bit @ 33.1 kHz | Half Rack unit. A minor upgrade to the original SC-55. | |
| Roland SC-55ST | 1993 | GM GS | 16 | 28 | 354 | 9 | 16-bit @ 33.1 kHz | Half Rack unit. Lower cost version of SC-55mkII. No display and only one MIDI input. | |
| Roland SC-55K | 1993 | GM GS | 16 | 28 | 354 | 9 | 16-bit @ 33.1 kHz | Half Rack unit. Japan-exclusive karaoke model based on the SC-55ST. No display or front panel operation but features dual mic inputs and built-in echo effects, all of which can be individually adjusted by the knobs at the front of the unit. Retains rear I/O from the SC-55mkII. | |
| Roland P-55 | 1993 | | 3 | 28 | 32 | 0 | | Piano module, with a limited set of instruments. Can be used in tandem with other GS/GM compatible synthesizers via their MIDI THRU ports to override certain instruments. | |
| Roland SD-35 | 1993 | GM GS | 16 | 28 | 223 | 8 | 16-bit @ 33.1 kHz | SC-50 with integrated MIDI sequencer. | |
| Roland SC-50 | 1994 | GM GS | 16 | 28 | 226 | 9 | 18-bit @ 33.1 kHz | SC-55mkII without the Roland MT-32 patches, only one MIDI input. | |
| Roland SC-88 | 1994 | GM GS | 32 | 64 | 654 | 22 | 18-bit @ 32 kHz | Half Rack unit, additional height for more controls, introduced multiple triggering and EQ, SC-55 map support (with differences). | |
| Roland M-GS64 | 1995 | GM GS | 32 | 64 | 654 | 22 | 18-bit @ 32 kHz | A 1U rackmount version of the SC-88. | |
| Roland SC-88VL | 1996 | GM GS | 32 | 64 | 654 | 22 | 18-bit @ 32 kHz | Smaller sized version of SC-88, with a same size and panel layout as the SC-55. Some units are marketed as an "Edirol" product and have a distinct beige finish. | |
| Roland SC-88ST | 1996 | GM GS | 32 | 64 | 654 | 22 | 18-bit @ 32 kHz | A black plastic box, with LEDs for MIDI activity. 2 MIDI ins, 1 out. There is one single button on the front panel for switching between SC-55 and SC-88 modes. | |
| Roland SC-88 Pro | 1996 | GM GS | 32 | 64 | 1117 | 42 | 18-bit @ 32 kHz | SC-55 and SC-88 map support, introduced Insertion EFX and unofficial XG compatibility. | |
| Roland SC-88ST Pro | 1997 | GM GS | 32 | 64 | 1117 | 42 | 18-bit @ 32 kHz | A black plastic box, with LEDs for MIDI activity. 2 MIDI ins, 1 out. There is one single button on the front panel for SC-55/SC-88/SC-88 Pro modes. | |
| Roland SC-880 | 1998 | GM GS | 32 | 64 | 1117 | 42 | 18-bit @ 32 kHz | A 1U rackmount unit similar to the SC-88 Pro, but with an enhanced "patch mode" and a newer DAC. | |
| Roland ED SC-8850 | 1999 | GM GS GM2 | 64 | 128 | 1640 | 63 | 20-bit @ 32 kHz | Desktop module that can connect via USB. Contains a new native map as well as SC-55, SC-88, and SC-88 Pro maps for backwards compatibility. However, compatibility with these units is flawed due to modifications made to the synthesis engine as well as improper mapping of older instruments. | [16][17] [18] |
| Roland ED SC-8820 | 1999 | GM GS GM2 | 32 | 64 | 1608 | 63 | 20-bit @ 32 kHz | Mobile MIDI device with no LCD display, successor of the SC-88ST Pro. USB-powered, but does not act as a full USB audio device. A software editor such as GS Advanced Editor is required to edit sounds. Despite similarities, patches and effects occasionally play differently from the 8850 - some samples on the 8850 are stereo while the 8820 versions are mono and vice versa. | |
| Roland ED SC-D70 | 2001 | GM GS GM2 | 32 | 64 | 1608 | 63 | 20-bit @ 32 kHz for INST, 24-bit @ 44.1 kHz or 48 kHz for WAVE | Digital audio-oriented desktop module version of the SC-8820. Contains A/D inputs as well as USB audio functionality when connected to a host system. This is also the only Sound Canvas module to have digital audio ports built in. The output can be selected either 44.1 kHz or 48 kHz. | |

### Virtual Sound Canvas

There is also the VSC, Virtual Sound Canvas, range of PC software which provide GM and GS synthesis on Windows PCs. Many versions of Cakewalk's Sonar software came bundled with a copy of VSC, though from Sonar 4 onwards they ship with the improved TTS-1 softsynth, which Roland has sold previously through its Edirol subsidiary as the HyperCanvas.

### Microsoft GS Wavetable SW Synth

Microsoft GS Wavetable SW Synth, included in instances of DirectX as an integral part of DirectMusic, and on Microsoft Windows since Windows 98, incorporates sounds from the Sound Canvas series licensed by Microsoft from Roland in 1996. A four-megabyte file, titled "GM.DLS", contains the sample set in DLS format. Under Windows 9x, Microsoft GS Wavetable SW Synth is available only if WDM-capable sound driver is installed.

### Apple QuickTime Software Wavetable Synthesizer

In 1997, Apple licensed the complete Roland Sound Canvas instrument set and GS Format extensions for improved playback of MIDI music files in QuickTime 3.0. This replaced the limited set of instrument sounds licensed from Roland in QuickTime 2.x.

### Discontinuation of Sound Canvas VA

In July 2024 Roland announced that it would not longer be supporting the Sound Canvas VA software from the Roland Cloud service. The Software would no longer be freely available starting September 1, of 2024.
