The Wersi and Lionstracs differ in that the Wersi comes standard with an enormous amount of high quality sounds as stock. In addition Wersi OAS 7 has several types of synthesis available (FM, Wavetable, Modeling) in addition to VST support, AKAI sample support, GM/GS sounds, and sampling. Both Wersi and Lionstracs support VST's so the user can load any particular VST they need into either system. Most VST's aren't free (some are quite expensive but well worth it), but they aren't required in order for the system to make sound. VST's simply expand your sound palette.

Lionstracs has recently added more stock sounds to the Mediastation and is also offering a new bundle of free GIGA sounds for the Mediastation owner. Its a great start but I'd like to see a sound library included that's comparable to Wersi's. The Mediastation has numerous sound sources such as sampling, synthesis, GM/GS sounds, and of course VST support. The Lionstracs supports far more VST's at one time than the Wersi.

The basic Wersi Abacus (about $7,500.00 USD) is far more expensive than the Standard Lionstracs Mediastation X-76 (about $3,500.00 USD). Of course Wersi and Lionstracs make more expensive versions (Abacus Duo Pro fully loaded is about $16,000.00 USD), Lionstracs X-88 Pro (around $6,900.00 USD). Wersi also offers the Ikarus, a lesser priced instrument but by no means cheap (around $5,500.00 USD). Which model is right for you depends on your requirements (61, 76, or 88 keys), what options you may need (expanded digital I/O, pedal board, RAM, etc.), and your budget.

Both the Wersi and Lionstracs offer the user possibilities that embedded type arranger/workstation just can't. Take this into consideration when considering the price of an open ended workstation.
