I think the layer system is great, and it comes to its own when making very 'organic' pads. This is all to do with each oscillator having it's own filter and envelopes so that each can be subtly different, adding variation. This is akin to the way Oberheim Four Voice or Vermona Perforumer behave, for example and is a gateway to very lush analog-style pads. However CPU consumption can put a stop to how big a sound I could get.
I could play a two oscillator pad with 8 notes poly, high quality setting with no issues at all (using Quad Q9300 2.3Ghz PC). When I added the third oscillator (at 8 note poly) realtime playback was not possible due to the crackling noise, so I reduced the quality to normal and all was well, however there was a subtle change in sound. I was able to get a lovely sound using four oscillators, high quality setting and 4-note poly though. That's more like it. This is where LuSH works well on my system: a big, 'organic' sound and not much CPU use.
With the following settings the bass can be very tight and snappy indeed (provided the cutoff/env amount/env ADSR is set correctly):
Amp source ENV1
(OPTIONS) Env retriggier set to normal
Bothe ENV set to 'trigger'
I think the layered mono bass sounds are also LuSH-101's strong point. And again, it's all to do with having independent filters and envelopes. One layer can have a very tight bass thud, but the other layer can have a bright buzzy tone, and the third layer can add some sub bass. *thumbs up*
When compared to other VA synths in my synth folder, the tone is different (pretty much as all other VA synths are different) so it's a good thing as LuSH offers yet another take on the analog sound.
