A budget late 1980's tone module, the EMT-10 contains 12 waveform-based ROM voices and has 8 notes of polyphony. The EMT-1 from the same time period is an FM-based complement to the EMT-10.
Due to its inexpensiveness and simplicity, it is often used for circuit bending.
The 12 voices available on the EMT-10 are:
Polyphony: 8 notes
Preset Patches: 12
Dimensions: 218 mm x 215 mm x 44 mm
Weight: 1.2 kg
This is a tabletop module.
