You haven't exactly told us what the TASK is for these tools...

But I tend to agree with Adi here. The software arranger is still a LONG way from rivaling a GOOD hardware one, so hardware here.

And recording is still FAR easier, better and more powerfully intuitive in a DAW.

But don't drop SIMPLE tools for recording from arrangers, please. It pains me that Roland have pretty much done away with ANY form of MIDI recording on pretty much all of their new keyboards, arranger and WS alike. They now expect you to cart around at least a laptop to USB the keyboard to, and transfer the MIDI data to it to record in this secondary tool. This is a TERRIBLE idea!

Who, in their right minds, would prefer this to a simple 'Recorder' that merely recorded the MIDI data, and even if the arranger has no further sequencing capability, allowed you to save this 'capture' as an SMF to transfer to a computer LATER...

You never know when the inspiration hits. But you know that, in all probability, your 'one take' audio recording is going to have maybe a few slight 'flubs'. Surely you would be better off creating an SMF, and editing the few flubs out?

You better have your laptop connected, if you have a modern Roland.

PLEASE do not go down this path!
