Notes Distorting & Cutting Off In Logic Pro Options

[the clash]

Hi I have just set up my keyboard/controller to work with Logic Pro.
Everything seems OK except when I choose certain sounds.

For example choosing
ES1-Factory Setting-008-Synth-007-SYN Pure.
Everything is fine and I can press as many keys as like I on my keyboard/controller without any problems.

But if I choose-
ES-2-Factory Setting-01-Pads-011-PD Male Choir HM.
And if I try to play more than 2 or 3 notes on my keyboard/controller the notes just cut off and if I play even more notes there is horrible distortion/warbling noise and sometimes all notes can cut off playing.

I realise my PowerBook is a under powered, could this problem be some kind of system overload or some other problem?
Thank You

Im using-
PowerBook G3 400Mhz (Pismo)
OSX10.2.5
384 MB RAM
Logic Pro
Novation K Station
Motu Fastlane

Try increasing the latency by increasing the Buffer Size in your audio setup. For instance, there could be a number like 256 or 512 in there, raising that to 1024 or 2048 will give you more simultaneous playback voices (at the cost of a higher latency time when hitting the keys).
