Actual MPC Live III / OS 3.10.1.12 capture from 1.1.2. The 1.2.0 UI is unchanged.
A WARM START

A little warmth
for your next loop.

A nonlinear oscillator mixer, four-stage ladder low-pass and rounded VCA now shape the sound at its source. Explore 63 factory voices rebuilt for this engine, plus a dry Init, then play bass, leads and your own chord changes inside your MPC. Sixteen oscillator pairs, hands-on envelopes and four Q-Link banks keep the sound close. Start with one of 64 sound presets, or build a chord arrangement across four banks of four slots.

01

64 starting points. Six familiar categories.

The ladder engine has 63 individually refitted factory sounds and a dry Init. Browse Bass, Keys, Synth, Lead and Pad. Per-sound low-cut and output trim provide practical starting levels.

02

A little movement goes a long way.

Drift adds slow wow and faster flutter. Filter LFO and independent tremolo have separate rate and depth controls, alongside a complete amp ADSR.

03

Your changes, across sixteen slots.

Start with four chords and expand to eight, twelve or sixteen. Keep four large touch pads on MAIN; assign physical pads with LEARN and add a manual location hint. Each bank keeps its own chord-preset selection.

04

Shape the voicing. Keep the groove.

Choose the available inversions for each chord, Open voicing and an independent ±2-octave offset. The 32 four-chord presets are starting points, and affect only the bank you are viewing.

05

Weight, warmth and space.

Combine Tape, Tube or Fuzz character with chorus and tempo delay. Filter cutoff and resonance sit beside the LFO that moves them.

06

An MPC instrument, from the first screen.

Play keyboard notes, chord triggers or both in Split mode. Mono and Legato apply to melody notes; chord pads keep their full voicings.

WHAT’S NEW · VERSION 1.2.0

A new analog heart.
The same hands-on instrument.

A new engine, from mixer to VCA.

Version 1.2.0 replaces the low-pass voice path with a four-stage nonlinear ladder, a saturating oscillator summer and level-dependent VCA rounding. This is the default engine, with no extra mode to enable. The existing band-limited oscillators, envelopes and effects remain part of the instrument.

Resonance that responds to level.

Nonlinear stages and a simultaneous feedback solve make resonance react to the signal. The ladder runs internally at twice the sample rate with output filtering. Higher resonance naturally reduces low-end gain; its top is limited below autonomous self-oscillation.

Every playable factory sound refitted.

All 63 Bass, Keys, Synth, Lead and Pad recipes have revised cutoff, resonance and filter-envelope settings, gentler external drive and remeasured output trims. Names, categories, program order and individual low-cut settings remain. Init keeps low-cut and effects off, while using the new engine.

The familiar performance surface.

The UI, 208 parameter identities, synth and CHORD Q-Link mappings, enlarged chord arrows and manual pad-position hints are retained. Band-pass, High-pass and Notch remain 12 dB SVF extensions; they are not ladder variants.

Saved settings load. Their sound changes.

Existing projects pass through the new mixer, filter and VCA, so parameter compatibility does not mean identical sound. Keep the 1.1.2 package and render tracks before upgrading if you need their old sound. The new engine costs more CPU; full hardware load certification is listed separately.

HEAR THE ENGINE CHANGE

Same settings. Different engine.

Three comparisons: bass, resonant lead and a four-note chord. Each plays 1.1.2 first, then 1.2.0, using identical saved settings and MIDI with effects off. A common +9.54 dB gain is applied to the whole demo; the pairs are not individually normalized. This is a native offline render, not a recording from the MPC.
