This video, via cube48, demonstrates a physical modelling ‘proof of concept’ V.A.S.T. Program.
Here’s what they have to say about the patch:
“Layer generates bandpassed and shaped noise, modulated by MonoPressure, ModWheel and FUN. Pitch is achieved in FX section by series of ‘374 PitcherB’ algorithms tuned with Pitch modulated by GKeyNum and PtchOffs by PWheel.
At the end of FX chain, body resonance is faked with slightly tweaked ‘384 Woodenize’ algorithm. It’s crude string synthesis with a lot of noise artifacts, limited articulation (there’s still plenty of room for improvement) but it’s funny how V.A.S.T. can be bent.”
Variable Architecture Synthesis Technology (V.A.S.T.) is Kurzweil‘s name for their semi-modular synth engine. It lets you create custom patches using a huge variety of building blocks, ranging from oscillators to filters to mathematical functions.
While best known for their realistic (for their day) sample-based patches, Kurzweil’s V.A.S.T. synths can also be used to create virtual analog sounds, FM patches and more.
