Hi, and welcome.
Its a bit of a design issue that's non trivial to explain but f you use the Arpeggiator, there will always be some form of "re-attack" of sounds (which can sound from unnoticeable, to cool to bad depending on the arp tempo and waveform used), Thats because that effect send a series of note ons and offs to the engine, and each time that happens the engine starts a new voice ADSR. (hence the thudding)
However if you use the wavesequencer, sequences of pitch changes can be made to alter the _currently_ playing voice.
Future versions of CS might have a feature where the arp is really sending the same pitch changes as the wavesequencer.
