I don't use this one. But by going on their website and checking a screenshot of their software you're mentioning I can see a command by the pitch command that says "glide".
So that would be it I guess.
For your other topic you have geist 1 or 2 as an equivalent to the drum rack in ableton. Pan, volum, shift, filters, and the parameters of the loaded samples, it's all modulatable through the integrated sequencer. Geist 1 is simpler maybe start with this one. G2 has a lot of modulators, etc, it's closer to Ableton, but it's also complicated. I don't have any bug with it, but many people complain about those. Not with Geist 1.
