10 Free Windows Synths You Can Actually Use (Bundle Included)

If your plugin folder is starving for quick-win synths with old-school bite, Infected Sounds has a whole shelf marked FREE. We’re talking ten instruments inspired by classics (Wasp, SimSynth, Minimoog, Poly D, 3xOsc, Little Phatty…), all Windows-only VST2/VST3, plus an All Free Synths Bundle to grab them in one go. Infected Sounds

TL;DR: Free, punchy, and unapologetically Windows. If you’re on macOS, these won’t load (confirmed by the dev in the bundle page’s reviews).

The Free Line-Up (highlights)

• Pol3y D — 4-osc poly beast inspired by Behringer Poly D. 128 presets, ladder & SVF filters, two LFOs, four envelopes, unison up to 16 voices. A surprisingly full “freebie” that’s even pulling 4.8/5 user ratings. Windows VST2/VST3.

• Mg Deluxe 3 — Minimoog-inspired, three oscillators (7 waveforms), ladder & SVF low-pass, unison, portamento. Windows VST2/VST3.

• XT Deluxe — Wasp XT-style with 128-waveform OSCs + sub, vowel filter, 3 envelopes, 2 LFOs (68 waves). Loads Wsp Deluxe presets. Windows VST2/VST3.

• Wsp Deluxe 5 — Classic FL Wasp vibes: dual OSCs + sub (128 waves), vowel filter, 3 envelopes, 2 LFOs. Windows VST2/VST3.

• Syn Deluxe 5 — SimSynth-inspired: 3 OSCs (128 waves), ladder/303/SVF filter modes, vowel filter, 11 LFOs + an LFO sequencer. Windows VST2/VST3.

• B4ss Deluxe 6 — 3xOsc-style bass machine: wavedraw oscillator, 98 waveforms, 8 LFOs + LFO sequencer, 3 envelopes. Windows VST2/VST3.

• Littl3-P 3 — Little Phatty-inspired: two morphing OSCs, ladder/SVF filters, 100 presets, 3 LFOs, unison/portamento. Windows VST2/VST3.

There are also entries for Littl3-S25 3 and 3x Deluxe 5, included in the free bundle list (with download totals and system info on the bundle page), even if some product URLs are currently offline. Windows-only, 7 GB disk for the full set.

One-Click Option: All Free Synths Bundle

Prefer to install once and be done? The All Free Synths Bundle packs eight (plus XT Deluxe listed on the page) into a single download. Windows only, VST2/VST3, and the developer explicitly clarifies no Mac support in the review thread.

Future-Music-style quick recipes

• 80s Poly Stack (Pol3y D)
  Unison on, detune small; ladder LP ~18 kHz; chorus/delay after the plugin. Save the preset, print the hook.

• Punchy Bass (Mg Deluxe 3 or B4ss Deluxe 6)
  Short amp decay, mild filter drive, envelope-mod the cutoff; parallel a fast comp for grip.

• Nasal Lead (Wsp/XT Deluxe)
  Engage Vowel filter, sweep formants with an LFO; add pre-delay reverb for vintage sci-fi.

• Rave Pluck (Syn Deluxe 5)
  303 LP mode, short decay, tiny resonance bump; automate cutoff into the drop.

Good to know (before you download)

• Platform: All free instruments listed are Windows only, VST2/VST3, 32/64-bit, tested from Windows 7–11. Individual pages show typical CPU/RAM suggestions (~3.2 GHz CPU / 4 GB RAM).

• Presets: Many include 64–128 presets and unison/portamento, with oscillators offering large waveform menus and vowel/ladder/SVF filters depending on model.

• Bundle footprint: About 7 GB required for the full free bundle.

They won’t replace your deepest flagship analog emulations, but for instant sketching, retro grit, and zero-cost fun, Infected Sounds’ freebies overdeliver—especially Pol3y D, Mg Deluxe 3, and the All Free Synths Bundle if you’re stockpiling. Start at the Free Plugins page, pick a couple, and get noisy.
