Penta

Penta, Prisma 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 Penta - as with all WERSI Digital Organs - may now be linked to and upgraded via the latest OX7 Virtual Tonewheel Drawbar Module.
