Acid bass on the TB-303's own diode ladder, envelopes, accent and slide, or a cleaner, modern voice.

Polyphonic wavetable synth with unison up to 16 voices, wave shapers, nine filters, a modulation matrix and built-in effects.

Stage keyboard: a sampled grand, electric pianos, tonewheel organ and synths, layered or split.

Analogue bass synth: drifting oscillators, a nonlinear ladder filter and oversampled voices, with a Floor and Sub Harmonics for a clean low end.
Installing
It puts the four plug-ins in the standard VST3 folder, where every DAW looks.
Most DAWs find new plug-ins when they start; some have a "rescan" button in their plug-in settings.
Each plug-in opens with its factory presets, sorted by category, ready to play.
In Pulse they sit alongside twelve more instruments and twenty-eight effects, and they work in live sessions with your friends. Try Pulse free for 14 days, then it's £60, once.
