"Demo to illustrate how the allophones from the SPO256AL2 can be chosen, triggered and processed in real-time

This board host the vintage General Instruments SP0256-AL2 aka SPO256-AL2 Narrator IC that was popular in the 1980s.
The SPO256-AL2 produces all the 59 phonemes of the English language.
It has a very recognizable 8-bit metallic sound.
These phonemes are individually addressable and can be chained together to create words or small sentences.
Our board adds two absent functions on the chip: pitch or inflection control and volume control.
The chip allows looping the last phoneme to generate interesting noise or steady MIDI notes.
MIDI control
MIDI note ON (first phoneme on note 36)
MIDI note OFF
Pitch Bend (can be used while the note is ON)
Velocity
Volume CC7 (can be used while the note is ON)
CV control
