The Quad Peak Animation System, aka QPAS, is a filter aimed primarily at stereo imaging and animation.

Fixed filter banks have been part of the synthesist's armoury almost since the appearance of the earliest Moog modular synths...

Built to Schlappi's same exacting standards, this all-analogue module can be an oscillator, LFO, filter or waveshaper...

Vowel is a digital oscillator module with all the gubbins you might need in order to get vowel sounds with just a trio of controls.

Looking for pre-mixer sweetening? Finaliser R‑EQ offers three-band parametic EQ, a two-way aural enhancer that works on the top and bottom end of the audio, and basic DSP effects like reverb and delay.

Classic low-pass gates are probably best associated with the Buchla modulars. However, Rabid Elephant decided against the vactrols, aiming to produce something faster, more accurate, durable and natural-sounding.

Formant Filter offers morphing between three different vowel sounds and via parallel band-pass filters, it delivers convincing vocal tones...

Rainmaker consists of a stereo 16-tap spectral delay paired with a 64-tap comb resonator, the latter sporting external triggering options that turn it into a (single-voice) Karplus-Strong synthesizer.

The original E-mu Morpheus was capable of real-time morphing in just one dimension, but today’s processors have much more power and can therefore offer 3D morphing — and in stereo.

Vermona’s Eurorack stable continues to grow with the addition of the TwinVCFilter.
