This would be my ideal all in one arranger workstation:

The build quality of my Wersi Abacus Duo Pro. Real wood and lots of metal may add to the weight, but I'll take that any day over some plastic toy.

The sounds from my Wersi using OAS 7 supplemented by Gigastudio sounds and analog VST emulations from John Bowen and Zarg Music.

The real time drawbars and organ sounds from my Wersi. Supplemented of course by the B4 VST that the Wersi is running.

The real time volume controls and programmable features of my Wersi.

The high definition 1920 x 1200 LCD screen from my Macbook Pro 17" built into the arranger.

The semi-weighted keybed from my Wersi, the 61 and 76 note keyboards feel fantastic.

The recording features, speed, and intuitive user interface from my Fairlight DAW for all audio and video recording.

Drum and percussion sounds from my Fairlight CMI III, AKAI MPC3000, Forat F9000, and Gigastudio.

The Vocalizer features of the Eventide H8000.

24 built in mic preamps from Forssell Technologies so I can record direct to disc without compromise.

Built in Manley Slam so I don't have to worry about level problems when tracking.

The Dual MP3/Audio Players from the Lionstracs Mediastation.

The real time Pitch Shift and Timestretch features from the Mediastation and my Fairlight.

The dual gooseneck lamp setup and dimmer system used by Lionstracs in the Mediastation.

The multi monitor outputs of the Mediastation so I can run three LCD's at the same time. One playing video, one showing me the Main edit screen, and the other displaying my sequences and cues.

Speakers from the Wersi Louvre. The Wersi speakers are the best I've heard in any arranger keyboard bar none. If you've never heard one in person, you just can't imagine the sheer power of the audio system. The Louvre isn't portable, but the sound system is awesome!

An additional subwoofer option using the massive NHT subwoofer from my NHT Pro Mastering system. Sometimes you just have to wake up the neighbors with earth shattering bottom end.

The open ended software capability of the Wersi and Lionstracs. This is where the future of keyboards is going. Wersi and Lionstracs just got the jump on everyone else.

From Lionstracs... the best customer service I know of. What other company lets you speak right to the CEO when you have a problem or comment? When's the last time you spoke to the CEO of Yamaha, Korg, or Roland when you had a question or concern?
