M Media Audio has released Curve Control, a dual-channel mix and mastering parametric EQ for Windows, macOS, and Linux.
Curve Control features twelve fully parametric bands across two independent channels, three operating modes, always-on level-dependent harmonic saturation, and a complete set of professional monitoring tools.
Twelve Bands, Three Modes
Each channel carries six fully parametric bands. Band 1 is a high-pass filter covering 20-400 Hz with four slope options: 6, 12, 18, and 24 dB/oct. Bands 2 and 5 switch between shelf and bell modes with independent Q, covering the low and high ends of the spectrum respectively. Bands 3 and 4 are fully parametric bell bands for low-mid and high-mid work. Band 6 mirrors Band 1 with a four-slope low-pass filter at 8-20 kHz. Every band carries its own frequency, gain, Q, and independent enable.
Three channel modes cover every mix and mastering scenario. Link mode gangs both channels – one set of bands shapes both L and R identically for standard stereo operation. Dual mode breaks the link entirely, giving each channel its own fully independent six-band curve – useful for asymmetric correction where a resonance lives on only one side, or where the two channels need genuinely different EQ treatment. M/S mode encodes the input to Mid and Side signals before the EQ chain, then re-encodes to stereo at the output. Channel A shapes the center. Channel B shapes the width. In Dual and M/S modes all twelve bands are fully independent.
Hardware Weight
A level-dependent soft saturation stage sits at the output of each channel after the EQ and output gain. It is not a user control – there is no knob and no bypass. It responds to drive the way a transformer responds: gentle settings at moderate levels produce a nearly clean signal, harder drives return audible but musically useful harmonic weight. The saturation is 2nd harmonic biased and calibrated at low drive levels. Oversampling at 2x, 4x, or 8x wraps this stage specifically rather than the full signal path, keeping added latency minimal.
Professional Monitoring Tools
Delta inverts the dry signal and sums it with the processed output. On a flat EQ the result is near-silence – engage a band and Delta isolates exactly what that band is contributing. Gain Sync ties the output gain to the inverse of the input trim so loudness stays consistent while evaluating tone. Mono collapses the output for translation checking. A switchable VU meter source covers Input, Output, and M/S levels – the stereo balance picture on a needle regardless of which channel mode is active.
Pricing, Formats and Availability
Curve Control is available now at $59 as a perpetual license with three simultaneous activations. It ships as VST3 64-bit on Windows 10/11, macOS 11 Big Sur or later (Apple Silicon and Intel Universal Binary), and Linux Ubuntu 22.04 or equivalent. AU 64-bit is included on macOS for Logic Pro, GarageBand, and MainStage. A free demo is available directly from the product page – the demo silences briefly every 30 seconds.
