When the main mode key is blinking green, it means your Alpha cannot find EigenD on your host computer. The keys will still light orange since the Alpha does this by itself without software running.

Check that your instrument cable is connected to the Alpha and the base station (if you have the base station pro check you've connected to the 'instrument' socket and not the 'extension' socket). Check that the base station is on, has a green light to show it connected to the Alpha, and check the USB cable is connected from the base station to your computer.

Try loading an Alpha setup from EigenD (in 1.1.14 this will be in the menu up by the clock on a mac). In later versions of EigenD there is a main EigenD window from which you can load setups by selecting them and pressing the 'load' button.

If this doesn't work, try shutting down EigenD and starting it up again, with the Alpha and base station plugged in and switched on, then load a setup again.

I would recommend downloading and installing a newer version of EigenD, 1.2.14-stable is the most recent stable version, or you can try 1.3.16-testing which is very nearly a stable release.

This just happened to me today --- I installed EigenD on my laptop yesterday and got it working just fine with Apple MainStage --- spent an enjoyable hour playing the "saxaphone"

I powered everything down when I was finished. This evening, when I turned everything on again , I got the symptoms described above. I tried replugging everything, I changed the USB cable between the base station and the laptop --- I unplugged/replugged the cable between the Alpha and the basestation (yes, it's in the instrument socket) but I can't get it working.

Loading setups again had no effect, etc

The base station light is orange, not green. But the alpha green light (main mode key) does flash occasionally, from which I infer the cable must be ok.

I was using the latest testing version, which I just downloaded yesterday.

This is the first time since I've owned the Alpha that I've seen this issue.

Any ideas?

That's good to hear, it sounded unlike anything we've really seen to date and we were struggling to find an intelligent response beyond 'put it in a box back to us'. It must have been in a very weird state, as the power and comminications actually travel on the same wires (decoupled with data transformers in the same manner as POE), so to have one without the other is very odd indeed. I can't really imagine how that happened, one of the pins must have been *just* making contact with high resistance.

As an aside, I've asked Dave to put a page on the Wiki describing the meaning of the different colours and patterns of lights on the Basestations and mute keys as when I went hunting I realised that we hadn't made this information properly public anywhere, and its really useful to know when one is having a problem like that.

Added. I hope that makes it clearer.
