GIALLUM

GIALLUM is an eight-voice bass synthesizer voiced dark. Sixteen knobs on one

panel — no menus, no hidden pages, nothing to dig for — and a melody generator

that writes the line for you.

THE GENERATOR, FOUR ENGINES

- DISCO CRITTER — disco and funk, five styles: Classical, Cosmic, Italo,

 P-Funk, J-Funk. Octave jumps on the beat, ninths and sixths as colour tones,

 and the silences that let a line breathe. 46 patterns.

- BAD BASS — rock and gothic, three styles: Original, Classic Rock, Punk Rock,

 with eight scales including blues and pentatonic. 34 patterns, from driving

 eighths to cold, minimal lines that sit still and let the track move around

 them.

- GIALLO — Italian horror. Seven styles: Suspiria, Profondo Rosso, Tenebre,

 Phenomena, Cannibal, Spaghetti Horror, Synth Stab. 22 motifs.

- BLACK BELGIUM — new beat, EBM and acid. 18 patterns, from relentless

 sixteenths to slow, heavy half-time crawls.

120 built-in lines in all, across eighteen styles. ROOT, SCALE and STEPS apply

instantly; DOOM drops the line an octave and darkens its intervals. GENERATE

writes a new one, RANDOMIZE reshuffles the character, LOCK keeps what works —

then drag the result straight onto a DAW track as MIDI, the clip exactly as

long as the pattern, whether it is 8, 16, 32, 64 or 128 steps.

Every step is editable on the mouse. VELOCITY and LENGTH set the feel of what

you draw, Shift + drag sets a single step, and the grid scrolls over three

octaves with the arrows — which turn red when notes are sitting outside the

window, so you always know they are there. Shift-click the magnifier and the

whole three octaves fit on screen at once.

THE MACHINE, ONE DARK VOICING

- WAVE / SUB — morphs the oscillator from saw to pulse, with an independent

 16' sub for weight that stays in the centre.

- CUTOFF / RESONANCE — a 24 dB ladder filter saturated at every stage: the

 roundness comes from the transistors, not from a drive at the end of the

 chain. Resonance runs to self-oscillation.

- ENV FILTRE — how far the envelope opens the filter, from a soft swell to a

 hard percussive snap.

- ATTACK · DECAY · SUSTAIN · RELEASE — a full envelope on both amplitude and

 filter, the filter running faster. That is where the bite lives.

- DRIVE / TAPE — valve saturation and tape character, oversampled four times

 so the grit stays musical.

- LFO — triangle, square or sample-and-hold, aimed at cutoff, pitch or pulse

 width, free or locked to the host tempo with dotted and triplet divisions.

- TEXTURE PANEL — five oscillator architectures placed before the filter: hard

 sync, FM, wavefold, ring mod and unison, with AMOUNT, COLOR, MOTION and RATE.

 At zero it is strictly bypassed.

Play softly and you hear it: velocity moves the level and the filter together,

the way an amplified instrument answers the hand.

Everything below 140 Hz is folded to mono, so the low end survives a club

system and a phone speaker alike.

EFFECTS & ECHO MONSTER

Three effects shared by all eight voices, placed at the very end of the chain,

so the echo repeats the finished sound rather than a voice on its own.

- CHORUS — two voices in quadrature. It widens rather than thickens, and it

 works on the whole spectrum, bottom included.

- PHASER — six all-pass stages swept slowly, with feedback.

- ECHO MONSTER — the delay line from MTR-4, with a high-pass and a low-pass

 inside the feedback loop, so every repeat comes back lighter and darker than

 the last. FEEDBACK and MIX, and the same time strip as MTR-4: milliseconds,

 or musical divisions with dotted and triplet.

All three sit at zero when the plug-in opens. Nothing is coloured behind your

back.

Plus GLIDE and ±4 octaves, 72 presets in BASS and DREADSCAPES, your own

presets saved, and MPE — per-note bend to ±48, pressure and slide.

FORMATS — MAC AND PC

- macOS 11 or later — Audio Unit (AU) & VST3, Universal (Intel & Apple Silicon)

- Windows 10 or later — VST3, 64-bit

Both versions are included in your purchase. After checkout you pick the one

you need on your download page — or take both, one licence covers you.

On Windows the installer is not code-signed yet, so Windows may show a

SmartScreen notice the first time: click More info, then Run anyway. The

included README says the same in two lines.

Licence: permanent, activate on up to 2 computers, Mac or PC — the same key

works on both. Your key arrives by email the moment you order.
