Connecting
The connections of your instrument are elegantly hidden behind the rear panel, so you won’t see the connections
even if you have cables plugged into them. Naturally, all connections will be in place. For the WERSI Verona, Vegas &
Abacus keyboard, connections for the Main Power, Lower Cabinet Speaker System (Left & Right Audio), Bass Pedals
& Volume / Expression Pedal Connector.
Further along to the left of the instrument audio / MIDI / in / out connections are further connection options for USB
(Motherboard USB ports), Video Out (For external monitors), Digital Audio in/out (Motherboard Connections).
Introduction
Congratulations on the purchase of your new WERSI OAS instrument. We can well understand that you, as the
proud owner of an instrument from our new family of WERSI OAS instruments (2011 Plus Range) do not want to
wade through the long, detailed information contained within the User Manual and Programmers Guide. However, we
recommend to read the introduction chapters of this user manual to quickly learn / familiarise yourself with the many
functions of your OAS instrument.
If you have the time and are curious enough to want to get to know your instrument in detail, we will happily guide you
through the many parts of your instrument via this user guide.
OAS stands for OpenArt-System. This means that this new generation of instruments is capable of almost unlimited
expansion. Although we here at WERSI have always been proud of the fact that our instruments are capable of ex -
pansion, we feel we have achieved special success in this respect with the OpenArt-System. A PC (Personal Com -
puter), which controls all functions of the central electronics is situated in the heart of OAS instruments. It is key to the
function of your instrument. However, a PC alone cannot provide the multiplicity of sound possibilities that the OAS
instrument range offers. For this purpose we have added additional high quality components. For example several
PCI cards with digital signal processors (DSP’s), an additional option module for vocal harmonizing effects, with which
layered voices are possible, and the proven / famous OX7 Tonewheel Sound Generator.
The digital signal processors produce, amongst other things the Longwave Sounds, the Reverb system, chorus and
delay effects, control the integrate digital mixer, play the Realdrums and control the signal routes of all sound sources.
The ‘bundle’ of high quality electronics built around a central PC offers ample reserves for expansion by activating
available software: soldering and DIY upgrades are things of the past, while the loading of software via CD/DVD/Blu-
Ray or USB is the way forward. Even though the OAS instrument range is built around a PC, you do not require any
PC / computer tech knowledge to operate your instrument. The PC interface remains hidden from the player. Windows
can be accessed, but it is not recommended to do so without professional knowledge or being competent at using the
Windows program.
PLEASE NOTE: The OpenArt-System continually records an ‘Error Log’ for WERSI service personnel to ac-
cess in case of malfunction. In the event of a customer using Windows and causing a malfunction, the Error
Log will show the action of the user. This may result in the warranty becoming void.
