In 1989, Wersi released a new range of instruments
which included the Alpha, Electra, Omega, Penta and Prisma. These were second generation
Digital Organs - first being excellent Comet.
Prisma, Penta and Omega were styled basically in the same Walnut (TL Model) or black
"open plan" cabinets which housed internal amplification and speaker cabinets.
The Omega however, had the bonus of drawbars in addition to digitally controlled voicing.
At the time, Wersi called the Prisma "Multi Keyboard". Here's why ...
- Multi MIDI :- Prisma can support multi-mode - in that it was able to transmit and receive
up
to nine MIDI channels simultaneously.
- Sounds :- 30 sounds are readily
accessible with 20 extra playable via cartridge. This, in effect, meant that those sounds
could be played directly at any time on the upper and lower manuals plus pedals.
- Presets
:- Up to 24 total presets available - sounds on both manuals and pedals, plus
accompaniments and rhythm patterns could be stored and selected as required. More could be
added via cartridge.
- Drawbars :- (Digital) Fully programmable 9 footages
from 16' to 1'.
- Transposer :- Push button control enables raising or
lowering of pitch in semitones.
- Other features :- Wersichord, Wersivoice,
Pitch, Noise Effects, Lower Manual hold, Key Split, Synchronized Start/Stop.
- Rhythm
& Accompaniment Orchestra :- Integrated sequencer which can store up to 300
bars. 24 Fixed rhythms and accompaniments, 19 fixed rhythm instruments (PCM). Patterns and
variations virtually unlimited via use of extra cartridge.
- Software :- 20
Factory-compiled cartridges with new sounds, rhythms and accompaniments.
- Demo
Discs :- Hady Wolff plays Prisma (Cassette)
The Wersi Prisma - as with all WERSI Digital Organs - may
now be linked to and upgraded via the latest OX7 Virtual Tonewheel Drawbar Module.
