I currently have a Audya 4 and I am having a love hate relationship with it. Here are the positives and the negatives.

Audya - Pros
* Un-paralleled Live sound. Those live drums
* Some of the best Rock, Funk, Ballad, Pop styles around
* Riff Function
* Really good bread and butter sounds; piano, rhodes, organ, sax, brass
* nice playability functions; Hold, Autocrash, Autofill, Pianist, etc.
* simple User Interface.
* Non song specific Styles

Audya - Cons
* Reliability and Quality - this is a big issue for me. how can you rely on this keyboard to do gigs on stage?
* Lack of styles on other Genres like Swing, Jazz, Ballroom, some rock styles like (cup of life), current songs; Ke$ha, Gaga, etc.
* Quantity of styles lacking
* some sounds especially the Guitars, strings, synth sounds are very lacking.
* I find using the Tyros left/right sound buttons more intuitive.
* No OTS or Music Finder
* sometimes the Audio drums get out of sync with the midi file!!
* Lack of ability to create styles IN THE KEYBOARD from scratch.

Tyros - Pros
* Unparalleled sounds across all categories.
* High Quality; Almost perfect track defect track record
* Custom sounds especially drums can be added and stored in Flash Memory
* Very easy OS and play controls.
* High number of styles across all Genres
* Large aftermarket and public domain style support.
* can create styles on-board.
* Tilt-able color screen

Tyros - Cons
* Overabundance of styles that are either song specific or just would not use on a gig
* Lack of RAW Live sound. (can this be adjusted and can it approach the sound of the Audya?)
* Lack of Rock, Pop, Country styles (at least from my experience with a Tyros 2)
* Lack of second Microphone Input
* no riff, makeup, style variation at all.
* no Hold function; meaning stop ALL style sounds keeping the drums playing when hands are lifted off the keyboard.

Have I forgotten any Pros/cons?

Which one would you choose to play live gigs either on a Pool Deck/Tropical; Restaurant/Bar gigs, VFW Hall gigs?

Equipment reliability is my top concern?

Thanks in advance for helping me.
