Does anyone here use midi controllers with a sound module or computer soft synth? I'm not talking about using a workstation/synthesizer as your controller (e.g. Motif 8 midi'ed to a MKS...WHEW GLORY!)....but a dedicated midi controller.
I have the M-Audio Oxygen 61

I don't really like it. It isn't touch sensitive. Granted I only bought it to use with my Native B4 software because it has 9 sliders. But the feel is horrible. It's very stiff and tough to play "organ" on.
I'm thinking about giving it away and buying an Evolution MK-461c.

I'm all about portability. I have a Yamaha S90ES and that joint never leaves the house. It was a struggle getting home from Guitar Center!

I bought a Yamaha Motif 7 classic about a year ago to take on the fly, but that joint is kinda big too. It's not huge. It's not a struggle to pack it up and go, but sometimes I just want to be able to grab my laptop in one hand and my controller in the other and roll.
I use Reason 4.0 more and more in live settings now. At first I was just using it to run drum tracks but now , if my drummer is running is own tracks, I can play keys through Reason. Especially since I have the samples of Steinway and Yamaha grand pianos and the MKS-20 sound module through Reason.
This is a picture of one of my software rigs.

In this picture, I'm using the MKS-20 E. Piano 2, a pad, and a steinway grand.
I can assign the sliders on my S90ES and Oyxgen 61 to control the levels on my software line mixer in Reason...

but I can't assign the sliders on my motif

, which is what I'd use out and about...so I was considering purchasing one of these...

...to just be a controller for my sliders...since my macbook pro has two usb ports.
We'll see though.
What are you all using?
