Concerning demos, yes there is always a multifilter and multiosc in the demo packs, that can be used to see how the osc/filter system works.
But it is quite difficult to demo more osc and filters, as it would either require additional time limitation, or ways to limit them, whereas they are mostly interesting for their edition possibilities....
But with approx 70 oscillators, and 40 filters, it becomes hard to make demo (my fault, i always thought the time that it would take to make demo would be better used for new devices

I'll try to make a demo for an SMOS oscillator (which are descendants of the Warp324) , but again, they are interesting when they are not limited....
See you later this week end as i come close to completion of the making of and the oscillators manuals.
