Transmutron by Boredbrain is available for pre-order and is a new dual FX loop crossover filter for advanced sound design projects with guitars and Eurorack Synthesizers.

Boredbrain, the developer of the Patchulator 8000 is back with a new interesting product. The Transmutron is a new dual FX loop crossover filter for guitars and Eurorack Synthesizers. Interesting here is that it allows musicians to use Eurorack synths with guitar pedals in a clever way. With the help of three different modes, it’s possible to achieve a wide range of results: Fission (crossover filter), Fusion (crossfader), and Fallout (resonant wide-notch filter).

The filters have selectable slopes of 12, 24, or 48 db/oct, which also affects the crossover filter, and greatly enhances the resonance of the wide-notch filter.

Overview

In the primary mode, Fission, the signal from your guitar, bass, synth, or drum machine is split into separate frequency bands, sent simultaneously to different effects, and then recombined to a single output (or two separate outputs). The Splitpoint parameter can be controlled manually or with an expression pedal, and simultaneously injected with a control voltage (CV) source for extremely dynamic reactions!

In Fusion mode, the Splitpoint instead acts as a pre-FX level crossfader, rather than splitting the signal into separate bands. This allows for less extreme blends, especially when modulating. In the third mode, Fallout, a resonant wide-notch filter is applied to both pre-FX channel signals, cutting a hole and creating a phasing-wah effect when using an expression pedal or LFO to sweep the Splitpoint back and forth.

To further shape the signals sent to your effects, the Transmutron is equipped with dedicated hi and low cut filters. In Fission and Fallout modes, the cutoff frequencies of these filters also define the end-to-end sweepable range of the Splitpoint parameter and its center frequency. The filters have selectable slopes of 12, 24, or 48 db/oct, which also affects the crossover filter, and greatly enhances the resonance of the wide-notch filter. If further separation of the parallel FX channels is needed, a dedicated phase switch is on-hand.

Both FX channels have two sets of sends and returns: 1/4-in for guitar pedals and line-level effects, and 3.5mm for eurorack level processing. For each channel, the 1/4-in and 3.5mm FX loops can be used simultaneously, as they are in series (3.5mm then 1/4-in). The FX sends are half-normalled so they can be used as buffered copies without affecting the returns. Additionally, the 3.5mm FX loops for each channel can be independently switched to pedal/line-level using internal dip switches, which allows for seamless integration with the Boredbrain Patchulator 8000.

How complex the reaction is up to you! From simple tone shaping using only a couple effects, to interconnected combinations of pedals and eurorack modulation madness, the Transmutron is just the tool you need to reactivate your effects!
