Mike Dean’s DLP releases free Smoke Mono 1 monophonic synth

Mike Dean’s DLP Audio has released Smoke Mono 1 as a free macOS monophonic synth, and the biggest surprise is not the name on the badge but the fact that it is the full thing, with no demo, no lite version, and no usage limits. The launch landed on April 20, 2026, wrapped in “Happy 420” branding and tied to a live drop from Mexico City, which gives the freeware release an unusually high-profile feel for a first plugin.

That matters because Mike Dean is not a niche software name. DLP says he has shaped modern music for more than four decades, with credits across Kanye West, Travis Scott and The Weeknd, and that Dean’s List Plugins grew out of decades of working gear and a personal wish list of perfect plugins. Smoke Mono 1 is the first free release under the Dean’s List Plugins banner, so it reads both as a usable instrument and as a statement of intent for whatever comes next.

On paper, Smoke Mono 1 sits squarely in classic subtractive monosynth territory. The early-access page says it was built from the ground up with PolyBLEP oscillators, a Moog-style ladder filter, note repeat and 50 presets. The live page adds two main oscillators with coarse and fine tuning, detune, a sub oscillator, two envelopes, one LFO with multiple shapes, white, pink and brown noise, drift, glide, limiter, stereo width and a note-repeat module for lead lines or simple sequences. For vintage-mono fans, that is a familiar recipe: strong on basses, leads and simple riffs, with the ladder filter doing the heavy lifting.

In everyday writing sessions, that makes Smoke Mono 1 a plausible stand-in for a real mono when speed matters more than ritual. It is available as VST3 and AU, runs natively on Intel and Apple Silicon Macs, and comes in a notarized macOS .pkg installer. DLP also bundles free stems, including kick, bass, smoke lead, pad and drums, which makes the release feel immediately usable rather than merely collectible.

The compromises are the ones experienced hardware users will notice first. The preset count is modest at 50, the plug-in is still Mac-only, and the first impressions point to some roughness in the GUI responsiveness and knob behavior. That means Smoke Mono 1 looks better suited to sketching parts, grabbing a quick mono line or covering a session when the real hardware is packed away, rather than fully replacing a beloved vintage monosynth with worn pots, hands-on immediacy and the quirks that no plugin can quite fake.

Still, a free monosynth from Mike Dean is the sort of release that cuts through instantly. It is rare to see a producer of this stature enter freeware with a genuine, no-strings instrument, and that alone gives Smoke Mono 1 a shareable edge far beyond the usual plugin drop.
