Sustain pedal choppy during Record only

[yamlan]

When I play VI's like Velvet, EW Pianos, Kontakt etc during record mode the sustain, when I press the sustain pedal on the keyboard, is choppy. The sustain notes do not consistently hold throughout the performance - they prematurely cut off.

This only happens during Record mode.

The sustain is fine during record mode in Cubase 5 so it has to be something with Pro Tools.

Completely clueless to why this is happening.

EDIT: *First I noticed that my RAM timings were at 9-9-9-24 and should have been at 7-8-7-20. Changed that then switched the S90XS to MULTI/SEQ PLAY mode. All is well again... :)
