What it does

A twelve-voice polyphonic synth modelled on the Commodore 64 SID chip, switchable between the 6581 and 8580. Each voice has three oscillators (triangle, saw, pulse, noise) with ring mod and hard sync, a multimode filter, three LFOs and a mod envelope through an eight-slot matrix, five effect slots, an arpeggiator and a step sequencer, plus scopes, meters and fourteen themes.

In the demo

Jade builds a patch from init in AUM with a Keystep, routing LFO 1 to cutoff and the mod envelope to resonance, then loads delay, chorus and reverb. She closes with the preset banks: wobble and FM basses, chord memory, a drum kit, SID organs, Commodore game leads and sequenced patches.

Worth knowing

iPad and Mac only on Apple platforms, no iPhone build. Windows and Linux versions are sold separately through the developer’s site. The preset save dialog is small on screen.
