What is the main purpose of the Keith McMillen CV Cable Kit?

The kit is designed to allow the QuNexus controller to connect to analogue gear by providing the necessary cables for MIDI-to-CV and CV-to-MIDI conversion. It ensures that the various signals generated by the controller can be correctly routed to external hardware.

Which specific controller is this kit designed for?

It is designed as an optional add-on specifically for the Keith McMillen Instruments QuNexus. While some adapters may work with other gear, the kit is tailored to the QuNexus's unique port specifications.

What types of adapters are included in the kit?

The kit includes a right-angle 3.5mm stereo plug to 1/4in stereo jack, a 3.5mm stereo plug to 1/4in mono jack, and a 3.5mm TRRS plug to dual 3.5mm stereo jacks. These provide a variety of connection options for different equipment types.

Can this kit be used for MIDI-to-CV conversion?

Yes, it provides the physical connection points required to send CV and Gate signals from the QuNexus to external synthesisers. This allows MIDI data from a computer or the keyboard itself to control analogue gear.

Is CV-to-MIDI conversion possible with these cables?

Yes, when used with the QuNexus, these cables can facilitate the transfer of CV signals from external hardware back into the controller to be converted into MIDI data. This is useful for using analogue sensors or oscillators to control software.

What is the benefit of the TRRS plug included in the kit?

The TRRS (Tip-Ring-Ring-Sleeve) plug allows for multiple signals to be carried through a single 3.5mm port. In the context of the QuNexus, this is essential for accessing multiple CV outputs or inputs simultaneously.

Does the kit include standard 1/4 inch instrument cables?

No, the kit focuses on adapters and specialised cables like the 3.5mm to 1/4in stereo/mono jacks. For long instrument runs, you would typically connect these adapters to standard cables like an Ernie Ball P06049.

How much does the Keith McMillen CV Cable Kit typically cost?

The kit generally retails for approximately £40.00 in the UK. This price reflects the inclusion of multiple specialised adapters that are not commonly found in standard electronics stores.

Are these cables suitable for DJs?

Yes, DJs who use the QuNexus in their performance setup can use this kit to integrate analogue sound modules or modular effects units. It adds a layer of hardware control to a digital performance environment.

Can I use these cables with a modular synthesiser patch bay?

Absolutely. The inclusion of 3.5mm and 1/4in adapters makes it compatible with both Eurorack (which uses 3.5mm) and larger format modular systems (which often use 1/4in jacks).

What makes this different from a standard Neutrik adapter?

While Neutrik makes high-quality individual adapters like the NA2MP, this kit is a curated set of multiple cables specifically chosen to cover all the I/O needs of the QuNexus hardware in one package. It includes TRRS splitters which are less common than standard Neutrik adapters.

Is the 3.5mm plug on the cable right-angled?

One of the key cables in the kit features a right-angle 3.5mm stereo plug. This design is helpful for maintaining a low profile on a crowded desk or synth rack and reduces strain on the QuNexus ports.

Keith McMillen CV Cable Kit

The Keith McMillen CV Cable Kit is a specialised accessory pack designed to facilitate connectivity between the QuNexus controller and modular synthesisers or other CV-capable hardware. It provides the specific adapters and cables required to convert MIDI signals to Control Voltage (CV) and vice versa, expanding the integration capabilities of portable MIDI controllers.

Overview

The Keith McMillen CV Cable Kit is an optional add-on package designed for users of the QuNexus smart sensor keyboard. Its primary purpose is to enable the translation of MIDI data into Control Voltage (CV) and Gate signals, which are the standard communication protocols for modular and vintage analogue synthesisers. The kit is essential for users who wish to leverage the QuNexus as a bridge between a computer-based or MIDI-based setup and an analogue hardware environment.

By providing a specific set of stereo and TRRS (Tip-Ring-Ring-Sleeve) adapters, the kit allows for multiple channels of CV output and input from the relatively compact physical ports found on the QuNexus hardware. This makes it a critical component for musicians who require a high degree of flexibility in their signal routing without needing to source individual, non-standard cables separately.

Contents and Connectivity

The kit includes a comprehensive selection of cables and adapters tailored to the QuNexus port configuration:

Right-angle 3.5mm (1/8in) stereo plug to 1/4in stereo jack: Ideal for connecting to standard patch bays or larger format synthesisers.
3.5mm (1/8in) stereo plug to 1/4in mono jack: Facilitates direct connection to standard mono instrument inputs.
3.5mm (1/8in) TRRS plug to dual 3.5mm (1/8in) stereo jacks: This allows the QuNexus to split multiple signals (such as CV and Gate) from a single output port.

These components are designed to handle the multi-functional nature of the QuNexus ports, which can send or receive multiple control signals simultaneously through a single connector.

Target Audience

This cable kit is specifically aimed at musicians, producers, and DJs who already own or are planning to purchase the Keith McMillen QuNexus. It is particularly suited for those working with Eurorack systems, semi-modular synthesisers, or vintage gear that lacks modern MIDI ports. Because it enables two-way communication, it is also useful for users who wish to use their analogue gear to control software parameters via the QuNexus MIDI interface.

Comparison to Standard Cables

Unlike standard instrument cables such as the Ernie Ball P06049 or generic patch cables like the Studiospares XLR range, the Keith McMillen CV Cable Kit is purpose-built for the unique pinouts of the QuNexus. While standard 3.5mm cables may physically fit the ports, they often lack the TRRS configuration required to access all available CV channels. Compared to generic adapters like the Neutrik NA2MP or LD Systems BNC cables, this kit offers a pre-configured solution that eliminates the trial-and-error often associated with custom modular synth setups.
