IIRC you can't have continuous frequency / Q changes applied while the 
note is on with SubSynth and PadSynth.

A way of achieving this kind of sweep would be to add an 'EQ' effect to 
the instrument and MIDI automate the frequency (and/or Q) in the same 
way you did it for the filter frequency (you need to select something 
like a Low-pass of course...).

Hope this helps,
