just got a Keylab 88 and just some problems.
I started with an external power supply 5V DC/1000mA and midi. But this was not successful.
As I switched on the Keylab, the display was quite bad to read, see picture "keylab88_ext_5V.jpg". And I was a little bit afraid too.
OK, then I started to play around with some stand alone VSTi. The middle C and G key did not work and after some time the sound got more and more crazy, wrong notes were triggered.
So I searched an USB cable and plugged it into my USB hub. Ah, the display
got readable and bright, see "keylab_USB.jpg" (same exposure of my cam!), but still playing nonsense.
After turning off and on the keylab worked well.
I checked my 5V DC, it had about 5.1V still connected to the keyboard and measured 2.1V between the
USB 5V and 0V pins at the and of my disconnected USB cable. Just for a test.
If you can take a view ofhttp://forum.arturia.com/index.php?topic=14223.0
there a different voltages mentioned. But with such a dark display I'm sure, the external 5V DC is not
the right voltage.
How can I get my keylab 88 working with an external DC supply?
