This guy is fantastic and the pa600 sounds great.

The reason I want to buy an arranger is because of the immediacy in allowing me to get new song ideas sketched. That and sometimes I just like to jam.

I've owned a DX7, a Trinity V3 pro, a Korg Karma and a Roland Juno but I just love being able to turn an arranger on and play......that's why I'm prioritising a new arranger over a new workstation. But I will be buying a Krome or Kronos soon too.
