Logic Express-oxygen8 Latency Issue, Go slow I'm new! Options

[SiGi]

Problem:
If I start a new project and set up an Audio Instrument - say the EXSP24 Grand Piano - I can play using the Oxygen8 and there is no latency as I am playing. However once I record the melody, when it it plays back, I am missing about every 3rd note, it sounds awful!

Also if I open the Tutorial and try to play the ES1 that's set-up there the Oxygen8 does not register any IN or OUT signals in the Transport window

Tried:
Audio Midi Set-up changing from Using Built in Audio to using the ULN2 but makes no difference

Gear:
Powerbook G4 1.5 Ghz 1.5gb Ram OSX 10.4.8
Logic Express 7.2.0
Midiman Oxygen8 (latest 3.2.2drivers) -Connected to Powerbook via USB
Metric Halo I/O ULN2 Mio Console 2.2f15 - Connected to Powerbook via FW

Many thanks for any suggestions

I'm stuck, there should be no difference between you playing directly or the MIDI playback of the score. In the end, the CPU should be solicited the same way by the ESX24… so either should have missing notes or none.

Now it reminds some very old problem a guy encountered here though I don't remember the cure, it must be around (it was in Logic too if I remember well but years ago…).

Have you tried with a lighter sample bank?
