Frank,
I downloaded the trial version en tried the OMB for just a couple of minutes.
What I do know now it is NOT suitable for 'real-time' perfomances.

It just takes too long before it recognizes chord changes etc. OMB still has a long way to go before it comes close to ordinary hardware arrangers.
(My PC is P4-3 GigHz huge memory.. so it's not my machine)

As long as OMB 'plays' prerecorded sequences it is just a sequence player IMHO.

I don't see your point about difference in 'live' situations compared to 'studio' situations. Arrangers do realtime arranging
and they do it well in both situations.

In my view it is not correct to state that OMB is 'far superior' to all hardware stuff on the market as long as OMB is not capable to do it in realtime...... and not telling you need a couple of extra hundreds of dollars to purchase Softsynths.

I'll stick with the hardware-stuff

btw. Until now I have'nt heard any impressive software arranger music. (Wersi, Lionstracs or EKO cannot convince me.... sorry for that)
