/************************************************************************************************* 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.
