The Harmonic Bass Machine Black Friday deal takes 34% off Unglued's bass synth plugin, bringing it to $45 until Nov 30, 2026.
It is a monophonic MIDI bass instrument. Unglued says he built it because he kept rebuilding the same bass chain in his sessions and wanted the sound without loading a rack of instruments, distortion and clipping every time.
The maker's tagline for the sound is clean lows, filthy mids, fizzy tops.
Everything starts with two sine oscillators. One is a clean fundamental. The other is an upper tone you place anywhere from the 1st to the 20th harmonic, picked on a harmonic ladder that shows how it relates to the note you are playing.
The harmonic oscillator takes one to eight unison voices, with up to 50 cents of detune and adjustable stereo width. The sub stays centred underneath it.
The sub and the harmonic each get their own envelopes or LFOs, including tempo sync, dotted and triplet timing.
From there the signal runs through a noise stage and a distortion stage, then a final clipper.
The distortion band follows the note you play automatically. The fundamental can stay clean while the mids take the damage.
There are 12 distortion shapes, with drive, dynamics, bias and wet/dry mix. A first-stage clipper sits ahead of it, and a final hard or soft clipper closes the chain with its own crossover that lets the low band through untouched.
Master Trim sets the output level.
Simple view lets you jump straight into the factory sounds and pick harmonics quickly. Advanced opens the full chain.
Both views edit the same sound, so you can start quick and go deeper when a patch needs it.
Yes. The Harmonic Bass Machine Black Friday deal takes 34% off Unglued's bass synth plugin, which brings it to $45. The offer runs until Nov 30, 2026.
It is the second of the two sine oscillators. You choose its pitch on a harmonic ladder from H1 to H20, add up to eight unison voices, and set detune up to 50 cents plus stereo width.
Six noise characters, 12 distortion shapes, a final hard or soft clipper, separate sub and harmonic envelopes or LFOs, 24 factory presets, four macros, A/B comparison, undo/redo and a randomiser.
Harmonic Bass Machine plays one note at a time from your MIDI input, always sounding the most recently played key, and it includes portamento sliding between notes along with pitch wheel control. Simple and Advanced views share one sound engine, so you can start from a factory preset and go deeper.
