The Ch.Svr music synthesizer module is a small utility module, offering several channels of signal-processing that will be useful in just about any modular system. As a condensation/extension of the sum/offset/attenuversion aspects of MATHS, it continues the great tradition of sculpting the control signals we use to sculpt our sound signals.

The X-PAN music synthesizer module is a compact and powerful 5 channel Voltage Controlled Stereo Mixer with Low Noise and High Headroom allowing for creation of complex panoramic audio imagery in just 10hp.

The XOH (miX Out Headphone) music synthesizer module is a stereo mixer, headphone amplifier and output interfacing module for your modular synthesizer.

Expando Expandi adds 8 freely assignable CV inputs to the Xer Mixa in just 4 HP. Connect up to two Expando Expandi to Xer Mixa for easy CV control over channel levels, pan, aux sends, and more.

Xer Mixa is a mixer with ten stereo-paired inputs (8 channels and 2 aux-ins), three stereo-paired output busses, tactile controls, and a 100% analog signal path with low noise and crosstalk, pristine sound quality, and ultra-high headroom. A built-in analog leveling amplifier is great for adding some punch to your mix. A digital control interface harnesses the true power of hybrid design, allowing for state save and recall, per-channel pan law and pre/post send settings, multichannel editing, and MIDI I/O.
