Echo Layla 24/96 Logic Exp 7 Powerbook And "buzz" Options

[kalki2000]

Hi all,


I am trying out Logic express Demo version and planning to buy the Pro 7.

I am getting a playback problem when interfaced with echo layla 24/96 via cardbus on g4 powerbook 1.5Ghz, 1.25GB RAM.

The audio tracks seem to play alright. But when the sequencer is stopped in the middle of the song over audio clips, I get a very fast loop of the underlying audio samples. The loop is so fast that it sounds like a buzz.
The setup however, works like a charm with mLAN on my Motif.

mLAN was not connected when the "buzz" occurred after the sequencer was stopped.

Things I did to rectify this problem:
Reinstalled layla drivers then logic express demo
Checked layla interface with iTunes, Garage band and the problem did not occur.
connection or disconnection of mlan does not seem to make a difference.
Sample frquency and bit rates are ok in the AudioMIDI and logic.
Can anyone please shed some light on the possibilities? I really like Logic and I hope this stickler can be fixed berfore I can buy it.

thanks

lepetitmartien and divan,

Thanks for your responses.

I kind of thought of the same thing as divan suggested.

However, there seems to be no problem with playback when monitored thro' mLAN.

So I guess mLAN and Logic are playing well together; except for a ground loop in the system and I can't seem to help that. However it is not causing any audio disturbance.
