The sound was somewhere between
the plummy tones of the Rhodes and the more aggressive 'throatiness'
of the Wurlitzer EP200. It was moderately successful and found favour
principally for its compact size and portability. However, its playability
was limited as a result of its mechanism - whilst it was touch sensitive,
it had a limited range and hence was not very expressive and it
had no facility for a sustain pedal.
That said, it was a good little electric piano that found
favour with Tony Banks (Genesis) and Chick Corea in the early days
of their careers (Banks used one on 'Nursery Crime' and 'Foxtrot'
but for some reason replaced it with the all electronic RMI ElectraPiano
for the later Genesis albums).
Several Pianet models were manufactured but probably
the most famous was the Pianet T which is featured in Nostalgia.
