GSDSP Quantum Filter

What it does

A filter bank with 11 types, including low and high pass, band pass, notch, shelves, bell and four ladder models, running three filters in series or two in parallel. Each filter has its own frequency, resonance, on and off switch, slope of 6, 12 or 24 dB, and a stereo or dual mono setting, and extreme resonance settings self oscillate. Underneath sits the modulation system shared across the Quantum range, where LFOs, random sources, envelope followers and 2D and 3D motion generators are dragged onto any control.

In the demo

Jade runs it in AUM on a generative Apriori patch, builds a modulation setup from scratch, then works through the factory presets and adds it to noise sources and drones.

Worth knowing

The modulation depth is where the app lives, so it rewards patching rather than preset browsing. Anyone who just needs a filter sweep will find the routing page more than they need. A separate desktop version exists at a higher price.
