Roland Sound Canvas SC-55
Skeleton by R. Belmont
Reference and LCD photo: http://www.synthman.com/roland/Roland_SC-55.html
http://en.wikipedia.org/wiki/Roland_SCC-1
The Roland SC55 is an expander (synthesizer without the keyboard)
from 1991. It has 24 voice polyphony, is 16 part multitimbral, and
outputs 16-bit stereo samples at 32 kHz. The synthesis engine uses a
combination of Roland's LA and straight PCM playback.
The front panel includes the power switch, a headphone jack with volume knob,
a second MIDI IN port, a large LCD, ALL and MUTE buttons, and a group of up/down
buttons for Part, Level, Reverb, Key Shift, Instrument, Pan, Chorus, and MIDI Channel.
The SCC-1 is an ISA board variant of the SC55 with a MPU-401 frontend added to
communicate with the synth.
