Plogue Chipsynth OPMZ: Four Yamaha FM Chips in One Synth
Plogue Chipsynth OPMZ is a multi-layer FM synth that emulates four classic Yamaha 4-operator chips from the DX100 and TX81Z, for $49.95 on Mac, Windows and Linux.
Plogue has released Chipsynth OPMZ, a multi-layer FM synth that emulates four classic Yamaha four-operator sound chips inside one plugin. It arrived on 28 September 2026 for macOS, Windows and Linux, and it costs $49.95. This is a first look based on the official product page, not a hands-on review.
At a glance: Chipsynth OPMZ models the Yamaha OPM, OPP, OPZ and OPZ2 chips, the silicon behind the DX21, DX27, DX100, TX81Z, DX11 and V50. Plogue reverse-engineered each chip from digital captures, including undocumented behavior, and wrapped them in a modern plugin with an eight-sound stack, SysEx patch loading and VGM playback. It runs as VST3, AU, AAX, CLAP and standalone for $49.95, and slots into the same family as Plogue's other chipsynth titles.
What is Chipsynth OPMZ?
Yamaha's four-operator FM chips defined a whole era of music. The OPM, formally the YM2151, drove the DX21, DX27 and DX100 keyboards as well as countless arcade cabinets. The OPZ, the YM2414, powered the TX81Z rack and the DX11, and it added new operator waveforms beyond the plain sine that the DX7 was stuck with. The OPZ2, the YM2424, refined that design and appeared in the V50 workstation. These chips are the reason so many late-eighties records, games and adverts share a certain metallic, glassy character.
Chipsynth OPMZ gathers all four into a single instrument. Rather than sample those synths or approximate their tone, Plogue emulates the chips themselves, down to quirks the original documentation never mentioned. That approach follows the same firmware-and-silicon path as Plogue's earlier chipsynth range, which already covers the DX7-era OPS7, the Sega Mega Drive MD, the Commodore C64 and the SNES SFC. OPMZ fills the four-operator gap in that lineup, and it does it with four chips at once.
What Chipsynth OPMZ gives you
Four chips, one panel. The headline is breadth. OPM, OPP, OPZ and OPZ2 each have their own tone and their own history, and OPMZ lets you reach any of them without loading a different plugin. The OPZ waveforms in particular open up sounds the original DX7 could never make, since they hand each operator a choice beyond the sine wave.
Deep, bit-level emulation. Plogue built the chips from many digital captures and modeled the parts other emulations skip. That includes the OPM's CSM mode, a full recreation of the noise generator, and the LFO reproduced with its exact hardware quirks. The TX81Z, a favorite for its slap-bass and detuned pads, is fully reverse-engineered. The point of that detail is fidelity: the aliasing, the modulation behavior and the small imperfections are what make these chips sound like hardware rather than a clean digital fake.
An eight-sound stack. OPMZ is a multi-layer instrument. Its stack page lets you layer up to eight sounds and place them across the keyboard with mappings, so you can split a bass under a lead, pile up a big unison patch, or build a multitimbral kit. That turns a set of vintage mono and paraphonic voices into something you can arrange with.
SysEx patch loading. If you own the hardware, or have collected the thousands of patches that exist for these machines, OPMZ reads SysEx patch files. Decades of DX100, TX81Z and DX11 sounds transfer straight into the plugin, which is a real shortcut past FM's famously steep programming curve.
VGM playback and analysis. OPMZ includes a VGM section that plays back and analyzes chiptune log files. For anyone scoring games, studying classic soundtracks, or working out how a favorite track was voiced, this is an unusual feature to find inside a synth. It treats the plugin as both an instrument and a study tool.
Modern host integration. Despite the vintage subject, the wrapper is current. OPMZ ships as VST3, AU, AAX, CLAP and standalone, supports NKS for Native Instruments Maschine and Kontrol S-Series keyboards, and runs on macOS, Windows and Linux. That is broader format and OS coverage than most boutique instruments offer.

Chipsynth OPMZ vs Native Instruments FM8
The obvious modern FM reference is Native Instruments FM8, the deep six-operator workhorse. The two aim at different goals. FM8 is a general-purpose FM synth with a large matrix, extensive effects and a huge preset library, built to make pristine, contemporary FM sounds. OPMZ is a historian's instrument, built to reproduce specific chips exactly, warts included.
| Plogue Chipsynth OPMZ | Native Instruments FM8 | |
|---|---|---|
| Engine | Emulates four real 4-op Yamaha chips | Original 6-operator FM |
| Character | Authentic vintage hardware, quirks intact | Clean, flexible, modern FM |
| Layering | Up to 8 sounds on a stack | Single engine, deep matrix |
| Patch import | Reads hardware SysEx files | Own preset system |
| Extras | VGM playback, chip-accurate noise and LFO | Arpeggiator, large FX section |

| Price | $49.95 | $99.00 |
Which to pick. If you want the exact sound of a DX100 bass or a TX81Z pad, with the chip's real behavior, OPMZ is the right tool and it costs half as much. If you want a broad, polished FM synth for new productions and do not care about hardware accuracy, FM8 remains the safer all-rounder. Many producers will happily own both.
Who Chipsynth OPMZ is for
Buy it if you love vintage Yamaha FM and want the real chips rather than a tribute. Retro game composers, synthwave producers and anyone chasing that late-eighties sheen will find the OPM and OPZ tones instantly recognizable, and the SysEx import means you can pull in existing patch collections.
It suits you if you already use Plogue's chipsynth range and want the four-operator piece to complete the set, or if you score games and can use the VGM playback and analysis as a working tool.
Skip it if you only need modern, general-purpose FM and have no interest in hardware accuracy. A six-operator synth like FM8 or the free Dexed will serve you better and cover the DX7 territory OPMZ deliberately leaves alone.
How much does Chipsynth OPMZ cost?
Chipsynth OPMZ costs $49.95, sold directly through Plogue. That sits in line with the rest of the chipsynth range, where the DX7-focused OPS7, the Mega Drive MD and the C64 title all sell at the same $49.95. There is no subscription. You can read the full specification on the official page.
If you are building a broader FM toolkit, our comparison points are FM8 for deep six-operator work, the free Dexed for DX7 emulation, and Arturia DX7 V for a modern take on the classic.

FAQ
Which Yamaha chips does Chipsynth OPMZ emulate?
Four four-operator chips: the OPM (YM2151) from the DX21, DX27 and DX100, the OPP (YM2164), the OPZ (YM2414) from the TX81Z and DX11, and the OPZ2 (YM2424) from the V50. All four live in one plugin, so you can switch chip character without changing instruments.
Can Chipsynth OPMZ load my old TX81Z or DX100 patches?
Yes. It reads SysEx patch files, so patches from the original hardware and the large libraries that exist for these synths transfer directly into the plugin.
What are the system requirements for Chipsynth OPMZ?
It runs on Windows 10 and later, macOS 10.15 and later, and Linux on kernel 5.4 or newer, all 64-bit. Formats are VST3, AU, AAX, CLAP and standalone, and it supports NKS for Maschine and Kontrol keyboards.
Is Chipsynth OPMZ the same as a DX7 emulation?
No. The DX7 uses a six-operator chip, which Plogue covers with the separate chipsynth OPS7. OPMZ focuses on the four-operator family, the OPM and OPZ line, which has a distinct and in some ways more varied sound thanks to the OPZ's extra operator waveforms.
