Curve Control

Dual-Channel. Twelve Bands. Hardware Weight.

Curve Control is a mix and mastering parametric EQ with six fully parametric bands per channel and three channel modes: linked stereo, fully independent L/R, or M/S with each channel running its own separate curve. Always-on level-dependent saturation adds 2nd harmonic weight at the output of each channel. Two large VU meters with switchable source give real-time level feedback on Input, Output, or Mid/Side. Professional monitoring tools built in: Delta, Gain Sync, and Mono. Oversampling up to 8x.

Six Bands Per Channel

Band 1 is a high-pass filter with 6/12/18/24 dB/oct slope selection. Bands 2 and 5 switch between shelf and bell with independent Q. Bands 3 and 4 are fixed bell bands for low-mid and high-mid surgical work. Band 6 mirrors Band 1 with a four-slope low-pass. Every band has its own frequency, gain, Q, and enable. In Dual and M/S modes all 12 bands are fully independent.

Three Channel Modes

• Link – Both channels ganged. Standard stereo EQ.
• Dual – Fully independent L/R curves. Notch a resonance that only lives on one side.
• M/S – Channel A shapes the Mid (L+R). Channel B shapes the Side (L-R). Re-encodes to stereo at output.

Hardware Weight

A level-dependent soft saturation stage sits after the EQ on each channel. Not a user control – no knob, no bypass. The harder you drive the EQ, the more harmonic weight comes back. 2nd harmonic bias. Oversampling at 2x, 4x, or 8x wraps this stage specifically to keep latency lower than oversampling the full signal path.

Mix and Mastering Monitoring Tools

• Delta – Hear only what the EQ is adding or removing. Near-silence on a flat curve.
• Gain Sync – Output tracks inverse of input. Consistent loudness while evaluating tone.
• Mono – Collapse to mono for translation checking.
• Meter Source – Switch VU meters between Input, Output, and M/S levels.
