tone module

Driver by R. Belmont and O. Galibert
|
||||
|
||||
Cost-reduced version of the MU80, uses the SWP00 which is a single-chip
|
||||
integrated version of the multi-chip SWP20. As a consequence has half the
|
||||
voices, loses the parametric EQ and the AD inputs. The sample roms are also
|
||||
smaller, and it only has one midi input.
|
||||
|
||||
A wavetable version exists as the DB50XG.
