An introduction to the OXI Instruments OXI Pipe MKII. The OXI Pipe MKII is a Eurorack breakout module for the OXI ONE MKII. It integrates the OXI ONE MKII's 8 Gate/CV outputs into a Eurorack environment for smoother integration with your modular system.

An introduction to the OXI Instruments OXI Split V2. The OXI Split V2 is a MIDI I/O expansion device for the OXI ONE MKII. It can expand up to 6 MIDI ports and 96 channels, enabling integrated control of multiple devices.

An introduction to the ADDAC200PI Pedal Integrator. The ADDAC200PI Pedal Integrator is a utility module that attenuates modular output to line level suitable for effect pedals and amplifies the return signal back to modular level. It also features 3.5mm/6.35mm jack conversion, providing a simple bridge between modular and external gear.

An introduction to the ADDAC200S Size Matter. The ADDAC200S Size Matter is a utility module that handles 6.35mm and 3.5mm jack conversion in a single unit. It features 3 pairs of passive conversion channels, requires no power, and is easy to install. Compatible with external effects and audio interfaces.

An introduction to the ADDAC219IN Stereo > Dual Mono. The ADDAC219IN Stereo > Dual Mono is an interface module that separates external line-level stereo signals into individual left and right mono outputs. It accepts a 3.5mm stereo TRS jack input, internally splits the signal into left and right mono, and outputs each through independent 3.5mm mono output jacks. It also boosts line-level signals to Eurorack level. With two conversion sections, this module serves as a bridge between external gear and your Eurorack system.

An introduction to the ADDAC219OUT Dual Mono > Stereo. The ADDAC219OUT Dual Mono > Stereo is a passive 3HP module that provides a simple way to send signals from your Eurorack system to external stereo gear. It combines two mono inputs (left/right) into a single TRS stereo output, attenuates the modular synth level down to line level, and outputs through a 3.5mm TRS stereo jack. With three independent sections, it can send multiple outputs to external gear at once.

An introduction to the ADDAC312 Gate Pedal. The ADDAC312 Gate Pedal is a foot switch controller that sends a +2.5V gate signal from the floor. Ideal for situations where you need to control recording, playback, or effect switching without using your hands, it extends the operability of your modular system. Equipped with a debounce circuit to suppress unwanted noise and false triggers. Beautifully finished in birch plywood with walnut veneer.

An introduction to the ADDAC313 Triple Gate Pedal. The ADDAC313 Triple Gate Pedal is an external pedal-type gate controller with three independent foot switches. Each switch outputs a stable +2.5V gate signal, serving as an intuitive interface for modular systems. Powered by a 9V battery for portability, it is suited for live performance and real-time control applications.

An introduction to the AI Synthesis AI026 Line I/O Interface. The AI026 Eurorack Line Interface converts between line-level signals (approximately +/-2V) and the signal levels commonly used by Eurorack modules (approximately +/-5V). This allows you to boost low-voltage line-level signals to standard modular synth levels, or perform the reverse.

An introduction to the ADDAC System ADDAC401 Gated Envelope Follower VS2. The ADDAC401 is a module that combines standard envelope follower functionality with eight gate outputs. The eight gate outputs produce gate CV corresponding to the input audio level across eight stages.

An introduction to the ADDAC System ADDAC304 Manual Gates. The ADDAC304 is a manual gate output module with eight momentary switches. While this module simply outputs gate signals while the buttons are held, it is widely applicable in building modular systems.

An introduction to the ADDAC System ADDAC305 Manual Latches. The ADDAC305 is a manual gate output module with eight latch switches. While this module simply outputs gate signals while the switches are ON, it is widely applicable in building modular systems.

An introduction to the ADDAC System ADDAC216 Sum & Difference. The ADDAC216 is essentially a two-section mixer, but this two-section mixer is capable of diverse CV synthesis processing. Each section has two CV input jacks, offering individual CV Attenuvert, mixing of two CVs, Full Wave Rectification, AC coupling, signal inversion, and average calculation -- all in a single module.

An introduction to the ADDAC System ADDAC217 Quad Gate to Trigger. The ADDAC217 is a 4-channel Gate to Trigger conversion utility module. It converts Gate CV signals with temporal duration into 1ms Trigger CV signals.

An introduction to the AI Synthesis AI001 Multiple. The AI001 Multiple is a compact 2HP passive multiple. Its DIY kit has few parts and can be assembled quickly, making it ideal for getting started with modular synth DIY.

An introduction to the ADDAC System ADDAC218 Attenuverters. The ADDAC218 Attenuverters is a module equipped with 3 channels of Attenuverters.

An introduction to the Mordax DATA. DATA is a multifunction utility module for Eurorack modular synthesizers. It includes an oscilloscope, spectrum analyzer, spectrograph, tuner, and voltage monitor, as well as a 2-voice digital oscillator and clock generator.

An introduction to the ADDAC203 REV.02 CV Mapping. The ADDAC203 REV.02 CV Mapping is a dual-channel CV adjustment module. In addition to attenuating/inverting input CV, it can also offset. It further features a CV input jack for offset and the ability to change the attenuator's maximum amplification to 10x gain.

An introduction to the ADDAC712 Vintage Pre. The ADDAC712 Vintage Pre is a dual-channel discrete gain stage amplifier based on a famous discrete preamp board used in legendary equipment from the 1970s. In short, it produces a pleasing saturation/distortion effect.
