(*)About SAND Channel-strip

SAND is a channel-strip featuring a combination of many devices into a single one.
We have faithfully recreated the sound characteristics of classic British high-end mixing consoles and recording studio hardware. It is characterized by a unique color with new incredible features, first of all the "Control" of the routing of the plugin components.
Another consolidated feature that is new to the software is what we call “ShMod”. This is a shape control for the attack behavior of the compressor. It allows you to fine-tune the attack shape so you can really customize the attack behavior for any audio source!
SAND is the natural choice for all those who “mix in a box” and musicians in need of authentic emulations of classic devices improved with Acustica technology and equipped with new parameters. It consists of four main components:

EQs (A mode, B mode)
Filters (A mode, B mode)
Comps (A mode, C mode)
Control

Features actually supported in Core9:

Variable speeds on vector nodes improving the sound quality of the compressors and allowing to reach very fast speeds and precision.
Envelope followers based on control sources.
Queue messages used for several widgets like knobs improving the behaviour, control, and stability of plug-ins.
Hiddend components fault-tolerant inside nebula/acqua engine to minimized crash/bugs.
New wrapper to get better balanced AAX format
Several minor fixes and improvements (about trimming, sample rate conversion, distribution of sample rate packs, fixes on loaded program rate).
This engine is linked to Nat4 to allows the full automatic compressor sampling.
Switchmode optimization reducing CPU loading
Lazy loading pattern introduced to improve the loading of the objects
