Roland/Edirol Sound Canvas lineup is a series of PCM-based MIDI sound modules and PC sound cards primarily intended for computer music usage, created by Roland Corporation. All Sound Canvas modules are compatible with General MIDI and MT-32 soundsets. Some models include serial or USB connection to computer.
A black plastic box, with LEDs for MIDI activity. 2 MIDI ins, 1 out. one single button on the front panel for sc55/sc88/sc88pro modes. Without Cakewalk StudioWare or GS Advanced Editor, you will be "flying blind" when using this. The same goes for the SC88ST and the SC7 units.
Mobile MIDI device with no display and the successor of the SC-7, SC-55ST and SC-88ST. Contains a new native map as well as SC-55, SC-88, and SC-88Pro maps for backwards compatibility. USB-powered, but does not act as a full USB audio device. GS Advanced Editor or another program is highly recommended when using this synth.
Desktop module that can connect via USB. Despite similarities, patches and effects occasionally play differently from the 8820 - some samples on the 8850 are stereo while the 8820 versions are mono and vice versa. Also has unofficial XGLite support (tested with a slew of XG MIDI files). Most of Roland's present-day electronic keyboards, has some of their sounds derived from the SC-8850.
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 44.1kHz or 48kHz, however the sound generation (samples on ROM) is still 32kHz internally.
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 HW mod is performed (external connector as external unit).
Desktop module. Can be used as a USB audio device, allowing for direct recording of processed MIDIs onto computer. GS sound bank is a mixture of SC-55, SC-88, SC-88Pro, and SC-8820/8850 samples. Contains 4 GM2 banks (Classic, Contemporary, Solo, Enhanced) as well as two Special banks in Native Mode and 3 MFX effects slots (1 per part - cannot be used jointly or stacked).
Mobile module. Does not have the SD-80/90's Enhanced bank as well as MFX. USB-powered, but lacks USB audio capability. Lacks a MIDI Out port and on-synth instrument preview function. The Roland editing program for this synth is also not as complex as that of the SD-80 and 90.
Compact, USB Bus powered and functions as a USB audio device. GS bank is more similar to that of the SC-50. Not very related to the rest of the SD family. Library instrument is still those from SC-8820/SC-8850 or 24-bit @ 32kHz.
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 Roland powered TTS-1 softsynth, which Roland has sold previously through its Edirol subsidiary as the HyperCanvas.
With SC-55, SC-88 and SC-88Pro compatible soundsets. 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).
