This is allready possible. But it depend on the VST, as not all VSTs output midi notes. The VST has to output midi notes from Sequencers and Arpeggios. If it does, then just record the output.
If the VST does'nt output midi notes, then you need to record the audio output, and then convert the audio to midi notes. There are tutorials on how to do this out there.
You can also change the Sequences and Arpeggios in the synth it self. Perhaps the preset are not even using notes to make a sequence. It could be made by different kinds of modulations. A DAW can't do anything about that.
Also keep in mind, that a synths Sequence and Arpeggios midi notes are only the notes. It's not the modulations and whatever else that can be going on. So having the midi notes does'nt have to be like having the same Sequence or Arpeggio.
