Yes, but since I only have the regular version of Live I really haven't done anything with 'm - to use either requires me to re-start in demo mode (which means I can't save patches).
Anyway, for nr.1: if it's the bass arp starting at 2:02, take a single oscillator, square wave, choose lowpass filter, turn resonance up slightly (say, 20% or so), enable keytracking for the filter cutoff, and turn the filter cutoff up or down until the resonance gives the desired effect. (my suspicion is that they re-used the sound before 2:02 where it just plays a static note). The difference is that with the arp, filter envelope modulation is also enabled; choose for ADSR something like 0 40% 0 0, and adjust the modulation amount to taste.
For number two, a quickly repeated sample of a bass guitar would also work (faster than full instructions on how to make a bass guitar-like sound); if you have Live's Suite version, then you also have Tension (physical modeling for string instruments) - choose a bass guitar patch in there, and sample a single note. Load that audio file in Simpler and switch Simpler to monophonic mode and set velocity to zero (so each note is equally loud). Throw a 16th note Arpeggiator device on it (no octave/note jumping required) and hold down a single note.
