SPO vox
This board host the vintage General Instruments SP0256-AL2 aka SPO256-AL2 Narrator. This IC was very popular in the 1980s.
The SPO256-AL2 produces all 59 phonemes of the English language. They can be sustained to generate signing.
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 CC1 (can be used while the note is ON)
CV control
- Phoneme
