Roland/Edirol Sound Canvas lineup is a series of General MIDI based PCM sound modules and PC sound cards primarily intended for computer music usage, created by Japanese manufacturer Roland Corporation. Some models include serial or USB connection to computer.
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.
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.
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.
PC based ISA card (8-bit). The SCC-1A and SCC-1B (different software packed with card) revision upgraded the board to 354 tones. First model technically not GM compatible (GM reset interpreted as GS reset).
Daughter board to attach to a SoundcardWaveblaster port. Also sold as SCD-15 and SCM-15 in bundle with MPU-401/AT. Internally 18-bit resolution, will be limited to 16-bit because of daughterboard connector, unless a hardware modification is performed (L/R external connectors or as an external unit). The SCD-15 was installed in Charlie Lab Megabeat One MIDI devices as well. Charlie Lab was very popular in southern Europe back in the 1990s/2000s.
Roland sold GM/GS products under its Edirol brand. The samples contained in the ROMs of these units do not in all cases mirror the original SC-7 / SC-55 GM/GS samples. GM2 is downward compatible with GM. The SD line was also sold under the "Roland" brand.
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'sSonar 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.
With SC-55, SC-88 and SC-88 Pro compatible instrument mappings. Most of the instrument samples are from the SC-55. A multipack containing the standalone MIDI synthesizer, a DXi plugin and a VSTi plugin. This is the only Windows NT OS family compatible version (Windows 2000/XP).
