mxm-mono-00

Sound

mxm-mono-00 is the collection’s large semi-modular. Its architecture comes from the Roland System-100 as the later plug-out arranged it: the 101 keyboard synth and 102 expander joined into one voice. MXM keeps that breadth but replaces patch cords and old panel geometry with a matrix.

Two oscillators feed a four-channel mixer. VCO-2 adds coarse and fine tuning, ring modulation, and two kinds of sync. Strong sync locks at any ratio. Weak sync holds near named intervals and rolls between them, which gives it a less rigid sound.

The filter path starts with a passive high-pass and ends in a diode ladder. Resonance trims some bass instead of compensating it away. The ladder can self-oscillate, and it runs at twice the project sample rate so the cutoff control reaches the intended top end.

This synth can keep moving after the key comes up. Two LFOs, two ADSR envelopes, sample-and-hold, and a matrix clock can drive a self-running patch. The output then passes through phaser, delay, and spring reverb in that order.

The matrix is part of the instrument

Fifteen inputs can each select one of fourteen sources. Every row is a normal plugin parameter, so a host can automate it and MXM Player can change it on a step. The matrix also exposes the machine’s default wiring. Pick the default cell and the familiar connection comes back.

The Patch view lights connected cells from the signal that is moving through them. Gates read as gates, control voltages show their position, and audio columns show their block peak. A patch that plays itself also shows why.

Interface

Four views split a dense instrument without hiding its structure.

Cards wrap as the window narrows. Oscillator pairs and envelope relationships stay together where a split would make the path harder to read. Zoom remains a separate control, from 75% to 200%.

The copper accent marks this instrument without taking over modulation colours. Those colours keep the same meaning across every MXM synth.

Presets

Fifty factory patches ship inside the plugin. They cover detuned saws, intervals, both sync strengths, ring modulation, noise, sample-and-hold movement, a self-running patch, a drone, and the three effects.

Init is generated from the parameter defaults. It starts with one saw through an open filter and VCO-2 seven cents sharp. Raise its mixer level and the two oscillators beat immediately.

User presets use the shared MXM browser with banks, categories, search, favourites, and readable JSON files.

Status

The tests show that the model is consistent and bounded. They do not prove that it matches a Roland System-100. That comparison remains part of release work.
