The navigation of the Mediastation is quite simple and not unlike any other arranger. There are dedicated control buttons for the GM/GS sounds, Organ Sounds, Linux Sampler, MS Synth, Styles, MP3/Audio player, Performance setups, and more. You can also select sounds, styles, and do edits by touching the TFT touch screen. Changing sounds and styles on the fly isn't an issue no matter what sound source you are using i.e. GIGA, GM/GS, MS Synth, or Audio files.

In addition to the dedicated buttons and TFT screen, there are numerous sliders to control envelopes, volumes, organ drawbars, etc. The sliders and corresponding buttons are programmable as well.

The dual MP3/Audio players are a fantastic feature. The real time pitch shift and timestretch allows you to import audio, set the tempo and pitch, and change it on the fly if needed. Imagine having background vocals playing directly from the audio player in perfect sync with your styles and sequences. Need to do a key change but have your recorded background vocals match the key change? No problem, pitch shift it without changing tempo!

With each software update I've seen the Mediastation improve dramatically. Its still not as simple to operate as the Wersi but given the fact Wersi has had a 6+ year jump on everyone else making Open Ended arrangers, that's to be expected. The Mediastation offers an alternative to the Wersi at a much lower price. Current arrangers by Yamaha, Korg, Roland, GEM, Ketron, and others simply aren't in the same league as these two arranger/workstations.

As I've said in previous posts... the Mediastation can be as simple or as complex as you want it to be. I suspect most people who buy a Mediastation will never scratch the surface of what it can do.
