1 press
PUNCH's LISTEN finds where they clash, sets the ducking and balances the subs.
Live
PUNCH draws your real kick and bass on one clock, with a line that falls each time it cuts.
±1 dB
RETROVERSE 90's Vintage knob is loudness-matched, so what you hear is the tone changing.
Your look
RETROVERSE 90 has 3 themes and PUNCH has 7. Each changes the whole interface, and the sound stays the same.
Customize
Both plugins come with themes that change the look of the whole interface, never the sound. This front page wears Paper.
Theme
Inside PUNCH
Press LISTEN while your track plays. PUNCH finds where the kick and bass clash, sets the ducking and balances the subs.
Live screen
Your real kick and bass waveforms, one above the other on the same clock, the way they look in a playlist. A line between them falls every time PUNCH cuts.
Inside RETROVERSE 90
Six sections, one signal path. Pick a section to see what it does to your sound.
Tone
Six stages that take a clean signal from polished to played-out: low-mid body, tape, analog drive, sampler crunch and a resonant filter.
RETROVERSE 90 before and after
Press play, then switch between Dry and Processed. Both takes run in lockstep, so the music never jumps.
90s R&B Keys
Silky, wide keys with a gentle micro-detune and plate.
Every processed clip is an unedited render from the RETROVERSE 90 engine. The source is one synthesized test phrase of plucked notes, kick and hats, so these clips show how each preset treats the same material. Preset names describe their intended instrument, not this source.
Compatibility
Both plugins are being prepared for macOS. Windows is in testing for RETROVERSE 90 and planned for PUNCH. Each product page lists exactly what has been checked.
Why BUTZ AUDIO
If a knob or a reading is on screen, it does something real. PUNCH's screen stays dark rather than draw a signal that isn't there.
