Free means free — no account, no trial timer, no watermark. If they earn a place in your sessions, Support Deestech. Already on DEES TAPE for Mac & PC? They're built into the VST BOX, no download needed.

Deestronix Deestress Comp — gunmetal rack faceplate with INPUT and GATE, ATTACK and RELEASE either side of a gain-reduction VU, ratio lamp buttons from 1:1 to NUKE, and an output LED meter.
Deestress Comp — the signature squeeze
Deestronix · compressor · free

Deestress Comp

Punchy peak compressor, all the way up to NUKE.

The signature squeeze from the DEES TAPE rack. Eight ratios from a gentle 1:1 to NUKE; INPUT drives it in, ATTACK and RELEASE shape the grab, OUTPUT brings the level back, and the gain-reduction LED row shows how hard it's working. A GATE knob closes the noise between phrases.

TipsHigher ratio + faster attack = more aggressive. Match level with OUTPUT.

Deestronix · master · free

D'Master

Final remaster: presence, tone tilt, and stereo width.

The last stage on the DEES TAPE master, on its own. AIR lifts presence up top, WARM ↔ BRIGHT tilts the whole tone in one move, WIDE spreads the stereo image. Made for the master bus, but it sits happily on a vocal or a guitar bus too.

TipsA touch of AIR + a little WIDE on the master.

Deestronix Vintage Delay — ivory faceplate with walnut cheeks, TIME and FEEDBACK knobs on the tape-echo module and a MIX blend knob.
Vintage Delay — tape echo, wow & flutter
Deestronix · delay · free

Vintage Delay

Tape-echo repeats with gentle wow & flutter.

Three knobs and the tape-echo feel. TIME sets the repeat, FEEDBACK how many, MIX how much — with the gentle wow and flutter that makes the repeats sit behind the source instead of on top of it.

TipsShort TIME = slapback; longer = echo. FEEDBACK sets the number of repeats.

Deestronix Preamp — blue rack faceplate with the DRIVE knob, IRON and AIR tone knobs, and an output VU with a transformer lamp.
Preamp — console color · drive · iron · air
Deestronix · preamp · free

Preamp

Neve-style console color that warms and glues the signal.

The rack's input stage. DRIVE pushes the signal into a transformer-style curve, IRON thickens the low-mids the way big console iron does, AIR opens a silky top. Put it first in the chain and everything after it sits a little better.

TipsDRIVE 9–11 o'clock = glue; push further for grit. IRON thickens low-mids; AIR adds silky top.

Deestronix Gate — slate rack faceplate with THRESHOLD, ATTACK, RELEASE and RANGE knobs and an attenuation LED meter with open and closed lamps.
Gate — threshold · attack · release · range
Deestronix · gate · free

Gate

Noise gate: shuts the hiss between phrases.

The DEES TAPE rack gate on its own unit. THRESHOLD sets where it opens, ATTACK how fast it lets a note through, RELEASE how it closes behind it, and RANGE how far down the floor goes when it is shut — from a gentle expander to a hard mute.

TipsSet THRESHOLD just above the room noise, then shorten RELEASE until the tail stops pumping. Pull RANGE back for a softer, expander-style close.

Deestronix LA-D Leveling Amp — brushed-aluminium faceplate with GAIN and PEAK REDUCTION knobs either side of a gain-reduction VU meter.

Deestronix · leveler · free

LA-D Leveling Amp

Optical-style leveler — smooth, transparent level control.

The rack's LA-D on its own cream panel. PEAK REDUCTION sets how much the opto element leans on the signal, GAIN makes the level back up, and the VU needle shows the gain reduction as it breathes. Program-dependent release, so it never sounds like it is working.

TipsDial PEAK REDUCTION for 3–6 dB of movement, then make up with GAIN.

Deestronix De-Ess — sage rack faceplate with FREQ and AMOUNT knobs, a sibilance-reduction LED meter and the sidechain LISTEN button.

Deestronix · de-esser · free

De-Ess

Tames harsh 'S' and 'T' sibilance on vocals.

Split-band de-esser from the rack. FREQ sets where the hiss lives, AMOUNT how hard it ducks that band alone, and LISTEN solos the sidechain so you can hear exactly what is being caught. The body of the voice is never touched.

TipsSet FREQ where the hiss lives (4–9 kHz); raise AMOUNT until the ess softens — back off if it lisps.

The rack's graphic EQ: six faders at 80, 220, 500, 1.2k, 3.2k and 8k Hz, ±12 dB each. Fast tone shaping you can read at a glance — clear the mud, lift the air, done.

TipsCut before you boost. Pull 220–500 Hz to clear mud; lift 8 k for air.

Tape Saturator

Warm analog tape drive and harmonics.

The rack's tape stage on its own. DRIVE pushes the signal into the tape curve for warmth, glue and harmonics, OUTPUT trims the level back so you can compare fairly. Two knobs, instant character.

TipsDRIVE for saturation, OUTPUT to keep the level even.

Deestronix Dimension — midnight-blue rack faceplate with RATE and DEPTH around an LFO meter, plus MIX and WIDTH knobs.

Deestronix · chorus · free

Dimension

Analog chorus for width and shimmer.

Two quadrature-modulated voices, the way the classic dimension boxes did it. RATE and DEPTH set the movement, MIX how much of it you hear, and WIDTH spreads the two voices across the stereo field.

TipsLow RATE + medium DEPTH thickens; raise MIX for lush. Great on guitars, keys, backing vocals.

Spring Reverb

Vintage spring-reverb tank — drippy and boingy.

Four damped springs into a dispersion pair: the drip, the boing and the splash of a real tank. DWELL sets how long the springs ring, TONE darkens or brightens the tank, MIX blends it under the source.

TipsDWELL sets length, TONE darkens or brightens the tank, MIX blends. Try it on guitar, snare, or vocals.

Already in the VST BOX.

FAQ
Where do the plugins install?

Mac: the .dmg's installer puts the VST3 in /Library/Audio/Plug-Ins/VST3 and the AudioUnit in /Library/Audio/Plug-Ins/Components. Prefer a per-user install? Drop the bundles into the same folders under ~/Library/Audio/Plug-Ins/ instead.

Windows: unzip and move the .vst3 folders into C:\Program Files\Common Files\VST3. Then rescan plugins in your DAW.

Do these work inside DEES TAPE?

Yes — they're built in. DEES TAPE for Mac & PC has the Deestronix effects and CLEAN Air inside the VST BOX with no scan, and the phone app carries the same rack. You only need these downloads for other DAWs.

Which DAWs?

Any VST3 or AudioUnit host: Logic Pro and GarageBand (AU), Ableton Live, Reaper, Studio One, Cubase, FL Studio, Bitwig, Reason and more. Pro Tools needs AAX, which we don't ship yet.

Are the Deestronix plugins really free?

Yes. No account, no trial timer, no watermark, no “lite” version. If they earn a place in your sessions, Support Deestech — it goes straight into the next build.

Are they the same as the phone app's effects?

Same DSP, ported knob-for-knob from DEES TAPE's FX chain. What you dial on the phone dials the same on your desk.

My DAW doesn't see a plugin after installing.

Rescan plugins in the DAW. Logic and GarageBand only scan AudioUnits at launch, so quit and reopen them. On Windows, check the .vst3 folder landed in C:\Program Files\Common Files\VST3, not inside a subfolder.

How much are CLEAN Air and Neo TUBE?

Both are in the store now, each with a 14-day free trial and one lifetime license for up to 5 computers: CLEAN Air is $29 once and Neo TUBE is $19 once. Mac VST3 + AU first, Windows following — the same key will work there too.
