Thanks for your responses. Great insights.

My DAW can really do everything except being a good tool for spontaneous composition. The arranger really does this well for me. Just select create a simple drum backing and off I go for some riff creation.

Workstations I have looked and they are more expensive with less sequencing/arranging. They are also lacking .wav recording or usb audio unless going to MOTL ot TOTL. My DAW can really outshine it at this point.

I am looking at a CT-X5000 second hand hopefully I will be able to grab it.
