These modules have awesome sounds and are very usable in today’s music. These have been used on a lot of records from various artists, from Toto, Brian Eno and Chick Corea and many others. This unit features 16 voices of polyphony for the FM section and another 16 voices for the sampled sounds. There are also 4 independent digital multi-effects which include Reverb, Delay, Chorus and Panning features. The screen is very a large size to view everything easily and make parameter changes. "
