Hi Dennis
Don’t dismiss all software boards because of one bad experience.
Wersi have been making software keyboards/organs for about 10 years, and there are no problems with live use. (You will find they are played on TV, in Clubs, Concert Halls and Stadiums, as well as at home and in the studio, plus Wersi has been making keyboards/organs for the last 40 years so are not new to the business)
TIP: If you want a Wersi Arranger, make sure you add or it already has the OAA (Open Art Arranger) software, as otherwise you will find it is more Organ then Arranger.
NOTE: Contrary to what has been said on some sites (Not Wersi) the OAA will not as yet directly play Tyros 3 styles, only up to Tyros 2 styles (They are a different format to the T2) and so they have to be converted to Tyros 2 Format first. (The same applies to all Yamaha Arrangers)
Used Wersi’s do come on the market every so often, and are easy to upgrade to the latest software/hardware, so there is no need to pay full whack for one. (The longer you keep it (You don’t need to change the whole board to get the latest technology) the cheaper it gets)
The new Pegasus Wing comes with OAA as standard.
Regards

Bill
