Vivid and animated, the Make Noise XPO is an analog oscillator that offers three distinct types of stereo animation for creating vibrant Eurorack patches. With the XPO and a curated selection of other modules, you can build a fully stereo signal path from start to finish. Paired with other Make Noise favorites like QPAS, Mimeophon, and X-PAN, it serves as the centerpiece of a remarkably rich playground for stereo patching.

The XPO offers no shortage of outputs, with 11 total simultaneous outputs divided into three stereo pairs and five mono outputs. Inside, plenty of analog magic creates the XPO’s colorful stereo image, achieved through stereo pulse-width modulation, stereo Vari-Timbre—inspired by their STO—and stereo wavefolding—borrowed from the DPO. With a symmetrical layout similar to QPAS, movement on both sides can be created with the Modulate-L and Modulate-R controls, scaled and set through attenuverters. Signals patched into the left side normalize across the module for easy movement, or you can patch a different signal from your system—related or not—into the right side for completely independent stereo play. For the Vari-Timbre and stereo wavefolder circuits, a Center parameter provides further shaping across both sides of the stereo field.

Regarding the mono outputs, these are arranged across the top of the module, covering traditional waveforms like sine, triangle, and sawtooth plus spike and sub. While the XPO truly shines through its stereo magic, these essential outputs provide a sonic foundation that cuts right through the center of a mix and are also valuable sources of audio-rate modulation to further enrich the timbres in your patch. Try using one of these to modulate the cutoff of a filter processing XPO’s stereo outputs, or self-patch into the XPO for grit and chaos.

Rounding out the feature set, the XPO includes additional inputs for essential oscillator functions. Although it is a single oscillator, two 1V/Oct inputs allow stacking sequences, transposition, or powerful FM. Speaking of which, the XPO offers both linear and exponential FM inputs, with the former featuring voltage-controlled FM index and a normalized connection to the sub-oscillator, while the latter offers an attenuverter. And of course, there’s a hard sync input for those characterful growls and sweeps—which sound great in stereo! Whether you’re completing your suite of stereo Make Noise modules or simply adding another colorful member to your setup, the XPO won’t disappoint.
