Bluezplayer, yes you can use the styles from Jammer Pro. It has been a while but I think there is a conversion that takes place within Jammer Live.

Fran, Jammer Live with its various styles sounds very good indeed - especially if you use good quality instruments. Good that you reminded us of this alternative.

As far as, I am concerned the best on the market today in terms of a software arranger are:

OMB
Live - Styler
Jammer Live

I know some have reported some difficulties with Live - Styler but if you stay with it and get all the startup files (*.ini, *.ns) and midi ports and channels properly setup it works perfectly. It takes a bit of effort but it is worth it. Live - Styler will work well with touch screens as another control surface. But they are all good.
