Modulr Strap

One oscillator with a sub and noise, a resonant filter, a key sequencer and an arpeggiator, played from your keyboard as a VST3 and Audio Unit.

Modulr Strap is a monosynthesizer after the grammar of the 1982 SH-101: one oscillator with saw, pulse and a sub that sounds one or two octaves down, noise, a high-pass and a resonant low-pass filter, a single ADSR on sliders, a portamento and a bender, an arpeggiator and a key-recorded sequencer, all as sliders in a strip over a 32-key keybed. It plays one voice, and it is a VST3 and Audio Unit plug-in.

Hear it

Five sounds, played as they ship.

Each clip is the plug-in itself: a patch is picked in the drawer and loaded, then a played line sounds on it, the way it is played into the plug-in from a keyboard. The bank holds fifty-two patches that make five distinct sounds, one for each role; these are one of each. No effects added, no mastering.

A Guy Called Gerald · Voodoo RayBass · SubAfter A Guy Called Gerald, Voodoo Ray (1988): a sub-bass line, the sub-oscillator forward under the saw. The settings are this product’s reading of the role, not any artist’s.

Portishead · MysteronsLead · SupersawAfter Portishead, Mysterons, Dummy (1994): a high lead on one saw with the filter open. The settings are this product’s reading of the role, not any artist’s.

SquarepusherBass · AcidAn acid bass, for an artist who names the SH-101 in the studio but no record: a low cutoff, resonance and a short envelope. The settings are this product’s reading of the role, not any artist’s.

Aphex Twin · Polynomial-CSequence · ArpAfter Aphex Twin, Polynomial-C, Xylem Tube EP (1992): a saw with a little sub, every note a short pluck. The settings are this product’s reading of the role, not any artist’s.

4heroFX · NoiseA noise sound, for a duo who name the SH-101 for effects and melodies but no record: noise through a resonant filter. The settings are this product’s reading of the role, not any artist’s.

The study

The editor, and the module it becomes.

The plug-in is built, and its editor is shown playing a patch. The Eurorack module drawn beside it, with its macro knobs and the control jacks under them, is a design study and is not built.

The Modulr Strap plug-in editor, playing a patch — The Modulr Strap editor, playing a patch: a blue handheld case, a strip of coloured-capped sliders, a bender lever, arpeggio and sequencer keys and a 32-key keyboard.

The Modulr Strap Eurorack module, 24 HP, in its case — The same study as a 24 HP module: a blue head with an amber patch window over twelve short sliders, each with a control jack under it.

The editor is the plug-in’s own, captured as it plays. The module is drawn by the specification’s own kit, and its values are illustrative, not measured. The design is SH-101’s grammar, redrawn in Modulr’s own words, and nothing on it is measured against the instrument.

The instrument it studies

SH-101, 1982.

The instrument’s own grammar, as the catalogue recalls it: the sections, the controls and the look the study borrows.

The compact mono grammar: a modulator, one oscillator with pulse width and a sub, a source mixer of saw, pulse and sub, a high-pass and low-pass filter with envelope amount, and a single attack, decay, sustain and release envelope, all on sliders.

A handheld mono synth in 24 HP: a blue moulded head with the name and an amber patch window, then a black strip of twelve short sliders with large coloured caps, grouped by section with white lettering, a CV jack under each.

Modulator: LFO rate and waveform
VCO: range, pulse width and its source, saw, pulse, sub level and noise
High-pass and low-pass VCF: cutoff, resonance, envelope, modulation and key follow
VCA: gate or envelope
Single ADSR on sliders, with portamento
32-step sequencer and arpeggio
32-key keyboard with a bender
Handheld case with a shoulder strap and a grip

The plug-in is built and on sale. The module is not.On saleModulr Strap is a working VST3 and Audio Unit and it is $25. It is not a copy of any instrument: no maker’s name or logo is drawn on a panel, and nothing is measured against the original. It is signed ad hoc, not notarized, so macOS will ask you to allow it. A downloaded copy stays silent until it is licensed, and there is no automatic way yet for a customer to receive a licence file. It plays one voice, and its sequencer is recorded from the keys you play: it holds the steps you write, not a pattern drawn in the host. The sound bank is fifty-two patches of five distinct tones; they are the product’s reading of a role, and none is an artist’s own setting.

Legendary is the catalogue of the Modulr Synths project: 43 design studies drawn with the specification’s own kit, 33 after the synthesizers of all time and 10 after the drum machines. The makers and years named here are the instrument’s; the names, the layouts and every value are Modulr’s own.
