Latency issue

[Dizz]

Hey guys, using the Ti Keyboard ver 1.03 with Logic Pro 6.4.2 on OSX 10.3.9 and Ableton Live 5 on a G4 Powerbook 1 ghz...

Ive found when using it as a sound card with Ableton Live 5 the cpu is up very high and causes lots of glitches then suddenly all audio stops and the only way to start it again is to turn the driver off in preferences and then back on again (it only stays on for a few seconds then this happens again!!)
In logic there is also a lot of glitches when used as an audio interface and as a plug in and Ive also found there to be too much latency for my liking especially when its been advertised as low latency with delay compensation...

Another prob is the automation!!!
Where is it???
Ive tried to automate any knob turn but it doesnt show up in Logic at all!
I thought this synth was goin to make my writing life easier!!
Am I missing something?

What would be the optimum settings for buffer etc for both Logic 6.4.2 and Live 5??

Cheers!!
Dave
