https://youtu.be/pwx72zQD0p8 Morphix - Morphing Wavetable Synthesizer Morphix is a polyphonic morphing wavetable synth and a faithful reconstruction of the lost 2005 FSR Morphite. Its architecture, parameters, and complete 64-patch factory bank were reverse-engineered from the original and rebuilt from scratch with JUCE — now a modern, multi-platform instrument themed after Aleph Void. A morphing oscillator feeds a state-variable filter, an amp VCA, and a stereo flanger, shaped by independent amplitude and filter ADSRs and a tempo-synced LFO. Sweep the morph parameter for evolving, animated textures — from glassy pads to gritty leads — all wrapped in a clean, dark Aleph Void interface. Features • Morphing wavetable oscillator into a state-variable filter (cutoff / resonance / env / keytrack) • Independent amplitude and filter ADSR envelopes • Tempo-syncable LFO routable to morph and cutoff • Built-in stereo flanger • Full pitch section with bipolar tune / fine • 64 factory presets recovered from the original synth • Import / Export your own .vstpreset patches • Branded Aleph Void UI — void palette, violet accent, JetBrains Mono type • AUv3 plug-in for use in GarageBand, AUM, Logic, and other AUv3 hosts Plays in your favorite DAW or stands alone.
