What was released
Void Enemy has released Plenitude, a free virtual analog synthesizer with three oscillators, a modulation matrix, and built-in effects for macOS and Windows. Bedroom Producers Blog reports that the finished instrument arrived on November 7 with 107 factory presets. KVR Audio's product listing gives the same date: release date: 7 November 2026.
Bedroom Producers Blog also reports the origin story. It started during Covid as Marco's personal project, and flatmates and university friends joined over time until the team reached seven people. That account comes from the blog's coverage, not an independent check.
Windows requirements and formats
- Operating system: Plenitude supports Intel and Apple Silicon Macs, plus 64-bit Windows 10 and 11.
- Formats: The developer's page lists the Windows build as VST3 plus a standalone app. The macOS build adds Audio Unit (AU).
- Version: The developer's download section lists version 1.2 for both platforms.
- Download size: Bedroom Producers Blog puts the ZIP files at roughly 125 MB for macOS and 46 MB for Windows.
The standalone app means you can try it without a DAW. That is handy if you only want to audition sounds.
The SmartScreen caveat
Bedroom Producers Blog warns that the Windows installer is unsigned, which may trigger a Microsoft Defender SmartScreen warning. That fits how SmartScreen generally behaves. Small independent developers often ship without a code-signing certificate, and unsigned files can draw a reputation prompt.
Two cautions apply:
- An unsigned installer is not evidence of malware, and a signed one is not proof of safety.
- Neither Bedroom Producers Blog nor the developer's page says anything further about the installer's security. I have no verified workaround to offer.
The usual hygiene still applies. Download only from the developer's own site and check the file's origin. If you work in a managed environment, check your organization's software policy before installing.
What the synth offers
The developer's page describes the instrument as a polyphonic synth with everything on a single panel.
- Oscillators: Three oscillators plus a sub. The six waveforms are sine, triangle, saw, square, pulse and noise. Tuning covers octave (±3), semitone and fine detune, and there are pulse width, pan and a distortion send. The sub has sine, triangle and square shapes and its own drive. There is also a hard sync switch.
- Filter and unison: The filter is resonant low-pass or high-pass with a dedicated ADSR envelope, key follow and a 20 Hz to 20 kHz range. Unison goes up to eight voices, with detune and stereo spread.
- Modulation: Two LFOs run free or sync to 23 tempo divisions, with delay and fade-in. The matrix is laid out as source, destination and amount.
- Effects: Tube distortion, reverb with pre-delay, size, damping and a three-band EQ, and delay with mono, stereo and ping-pong modes.
- Voicing: Eight-voice polyphony with Poly, Mono, Legato, Unison mono, Stack and Glide modes.
- Quality: An HQ switch selects 2× or 4× oversampling. The developer says offline renders always run at 4×.
Bedroom Producers Blog says the sub can bypass the filter, which keeps the low end intact while you adjust the brightness of the other oscillators. That detail comes from the blog; I did not find it on the developer's page.
Discrepancies to be aware of
Modulation slot count. Bedroom Producers Blog says there are six slots. The developer's site advertises a 12-slot mod matrix, and KVR lists 10 sources and 42 destinations. I can't reconcile these. Check the installed free build before relying on any one number.
Download flow. Bedroom Producers Blog says you can download Plenitude directly without an account or email signup. The developer's page, however, still shows a "coming soon" banner and a release-notification email form alongside the download links. Its own copy says the phone version of the page gets links by email. If a signup prompt appears, that is the page behaving as published. I did not test the links.
Hands-on impressions
The blog's reviewer calls it a decent synth to try. They like having every control on one panel and found the modulation matrix easy for beginners. They would not call it essential if you already own several synths.
The main complaint is legibility. Labels such as Resonance, Cutoff, Rate and Depth are too small, even for someone with good eyesight. The panel is resizable by dragging the bottom-right corner, which helps somewhat. The developer says the interface is drawn at 5700 × 4200, so it should stay sharp when scaled. On a high-DPI Windows laptop, expect to enlarge it.
Free now, Pro later
A Pro edition with an expanded matrix and additional controls is planned, but the current free edition is intended to remain free permanently. The developer's page says "Free, forever" and lists Pro as "Coming soon." Those are statements of intent, not guarantees. No Pro pricing or date has been published in the material I reviewed.
Bottom line
Plenitude is a free, 64-bit Windows 10/11 synth with VST3 and standalone support, easy to try if you already run a DAW. Before installing, expect a possible SmartScreen prompt, verify the download source, and confirm the real modulation-slot count in your installed build. This is a recent release, so independent hands-on coverage is still thin.
