A Groundbreaking FM Synth Engine

With its flexible wave shaping, dual-mode filter path with 23 different filter types, 6 envelopes with tempo-synced looping, 2 LFOs, and 2 ramps, the OPx-4 will become your go-to FM synth. It includes three insert FX and two global FX for use with 27 included AIR effect plugins, such as reverb, delay, distortion, modulation effects, and more. As a result, the OPx-4 is one of the most advanced synth engines ever to hit MPC.

Leave Your Sound Design Ph.D. at the Door. OPx-4 Makes FM Synthesis Easy.

FM synthesis works by taking classic oscillator waveforms and modulating them until they sound like something brand new. If you’ve ever experimented with FM synthesis, you know it can be complicated to understand how to make great sounds. OPx-4’s simple layout and easy controls make it a breeze to experiment with FM functions without needing a deep understanding of how it works behind the scenes. An easy-to-understand control scheme makes experimenting as easy as turning knobs until it sounds great!

Four Operators, Two Filters, Thirty-Two Mod Sources, ONE Great Sound

Using four FM operators and an FM operator matrix, you can craft almost any FM sound you’ve ever heard—or even those you haven’t heard of yet! You can adjust the values of each operator using specific on-screen controls for pulse width, formant, FM filtering, and FM shaping, as well as specific ADSR and FM oscillator envelope controls.

Built-In Effects Engine to Stylize your sounds

OPx-4 includes multiple effects like EQ, amp sims, reverb, delay, and modulation. Create brilliant shimmers, dark haunting echoes, or spacey washed-out DX-style electric pianos with a cutting-edge effects engine built right into the instrument.

Hands-on Control and Massive Modulations with Q-LINKs

When using OPx-4, you can assign any parameter to one of 8 macro-controlled knobs. OPx-4’s parameters are laid out to make full use of standalone MPC’s vivid touchscreen, and use MPC’s Q-LINK mapping to put the most valuable instrument controls at your fingertips! Sweep filters on the fly, adjust operators with a turn, and pump up the volume on OPx-4 with your Q-LINKS! The touch UI on MPC gives you instant feedback, and straightforward touch controls get you deep into sound design territory.

Sounds Mode: A Fast and Intuitive Way to get the Perfect FM Synth Sound with your MPC!

The new MPC Sounds browser for standalone makes finding and saving your favorite patch a breeze. Sounds mode for MPC lets you browse, change key ranges, and create massive performances! This colorful and easy-to-use interface will have you making a banger in no time.
