Logic Pro 8 kontrol 49 roadblock

#1
Has anyone else experienced compatibility issues between Logic 8 and the Korg Kontrol 49?

I turn on my iMac 2.66 intel Core 2 Duo, 2GB RAM and my USB connected keyboard is lit up, ready to go. With MAX/Msp running, the keyboard stays lit and working but after launching Logic Pro 8, the keyboard lights go out, and no input seems to get into Logic via the keyboard or controllers..

I had this light going out problem before (when I switched to Pro) but at least I could input MIDI data with my keyboard. Now--inexplicably--I can't do anything with the keyboard.

I just downloaded and installed KORG's latest driver. No change.

What the $@%$%@ is going on?

I used my KONTROL49 via USB and LC Xmu for quite a while with Logic 8 and there were no compatibility problems. After physically damaging the USB input I use it only via MIDI and now in Logic 9. Works well.

I turn on my iMac 2.66 intel Core 2 Duo, 2GB RAM and my USB connected keyboard is lit up, ready to go.
It is probably not a good idea to use this keyboard bus driven. The external power supply is always better.

Sounds like a problem with bus power. Logic cannot switch a keyboard completely off on its own.

I can't do anything with the keyboard.
If the lights go off and the keyboard is greyed out in the Mac's "Audio/MIDI setup" then it loses the power supply. Could be a weak USB hub. Try with the external power supply. And, not only for this keyboard but generally, use good powered hubs like Belkin or similar.

thanks for the reply

It is news to me that USB bus power isn't reliable but I'm guessing that this is good advice.

I've been digging around for the KORG adapter. Not sure where it is at the moment. (But I did run across it a few months ago.)

You seem to be saying, use the power adapter AND a powered USB hub. Would simply adding a powered hub be worth a shot?

thanks,

I just got a power adapter from zZounds for the Korg 49 and it works like a charm. Product info is:
Korg A30950 KA183 9VDC Power Supply for AX-Series Pedals

I wish the Korg 49 would map to Logic like it does Reason. Anyone have a trick for doing this? The manual mapping tool in Logic is a pain in the ass, IMHO.

Thanks,
Shawn

If it is now on a non-powered hub then a powered hub may help. But generally I think external power supplies are the way to go for all devices that offer such a supply. Your Mac is a music machine and not a power station ...
