I disagree and made several points to that effect in your old posts. I wouldn't have considered any arranger ten years ago and today I wouldn't consider anything except an arranger for stage use - they certainly have improved on their own terms or I wouldn't use one. But there is nothing to stop you from creating your own arranger if today's offerings don't meet your needs: the Open Lab's eKo could be customized into any configuration you could want, from sounds to control surfaces, the latest processors and moemory to every I/O you can imagine - in effect it could be the best arranger ever concieved - and it isn't selling because the price is too high. Those of us who want a fully-customizable arranger are making our own (see some of the FLR threads in this group). So there's nothing to stop you from making your own dream arranger with stock stuff if you have the time and money.

One other thing: you have to remember that the arrangers talked about on this forum are mostly the portable and less expensive kind... home arrangers that go from $10k and up include many features that we've been asking for but they don't get discussed here because we're not in that price market (I sit in on a forum of Yamaha CVP-series users and their needs/concerns are much different from ours).

Why don't you start your own thread on arranger technology instead of hijacking the threads of others?
