Patch of the Week: TRIPLE CROSS - Voltage Controlled Sound Switching with a Step Sequencer

video upload by AJH Synth Official

"The Triple Cross crossfader/panner module from AJH Synth & Tone Science makes a lot of things possible. Here it is being used as a voltage-controlled switch, to change between 4 incoming sounds, and send the chosen sound to its output. This means it can serve as a very convenient method of changing between multiple sounds, perhaps in a live performance, moving between different patches manually using the sturdy, tweaking-friendly controls. However, this behaviour can also be controlled by CV, so the process can be automated, and controlled by other modules, keyboards and sequencers.
In this patch a 4-channel/track step sequencer is being used - the excellent Erica Synths Black Sequencer. One sequencer track is used to send a melody to the VCOs and Gates to trigger the envelope generator. The other 3 tracks are controlling the 3 channels of the Triple Cross, to pan the Fade control hard left or right, like junctions on a railway track, so that the exact sound of our choosing arrives at the module's output, precisely when we want it.
Various combinations of the 3 VCOs, white noise, sub-octaves/sub-basses from the Ring SM, and animated sawtooths from the Wave Swarm are sent to 4 separate filters: The Transistor Ladder Filter, Sonic XV Diode filter, and both filters of the Gemini 2412 Dual VCF. A single Dual Contour Generator is controlling the VCA level, and the frequency of all 4 VCFs. The Sonic XV is also using its wave folder to generate a more unusual timbre from just a single triangle wave. The Triple Cross is a collaboration between AJH Synth and Ian Boddy of the Tone Science record label. It is an exceptionally useful module, being suitable for use with both audio, and control voltages, since it is DC-coupled. More videos featuring this, and other modules in the future.

The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself."
