HI Ian

Its good to hear about bands using arrangers, but in Europe there are thousands of bands using keyboards and the vast majority are workstations or synths.

The same applies to YouTube; you see thousands of bands using Workstations/Synths, but very few using arrangers.

Your last 2 paragraphs points out the differences brilliantly, for Home Users, OMB and as a scratch pad for getting a good backing track going in a studio, then the arranger blows Workstations/Computer based systems out the water.

Once that work is done however, you want top notch sounds, and the ability to fine edit and modify it to get something really unique, and just like a Sedan is no good off road, an arranger is not suitable to get a really top notch unique sound production. (It was never designed for that purpose)

In the end it all comes down to what suits you, in your case the T4 does everything you need, (Just as other arrangers do it for their users) but for me, I enjoy the software route, as I find the limitations (For me) of an arranger make them not suitable. (There is no right or wrong with either, as they were both designed for different jobs)
