The Yamaha C1 was released in 1987 and is basically a 80286 processor based PC with 8 built in MIDI ports for use in applications where there are many MIDI instruments to address.
|
||
|
||
By 1987 some machines which were capable of responding on multiple MIDI channels were appearing, and some earlier machines could only function in "omni" mode which meant that they needed a whole 16 channel port to themselves or they would play every time a note intended for another instrument was sent.
|
||
|
||
Since MIDI information is fairly 'slow' in respect to what even a about 10Mhz computer can handle 8 output ports with buffers wasn't a difficult thing to pull off for even an old 286 apparently.
|
||
|
||
Various DOS applications were included, among them the Voyetra Sequencer which was set up to run all 8 ports.
