Feedback everything. Add tonnes of flavour to your Eurorack. The Bastl Instruments and Casper Electronics Dark Matter is a useful and incredibly fun Eurorack module from the Czech manufacturers. At only 13hp in size, this relatively small module packs a huge punch. Using the Dark Matter you can explore the complex behaviours of amp circuits and push them to their limits. With four flavours of voltage controlled overdrive, there is a lot of sonic possibility inside the Dark Matter, and when added to your workflow, Dark Matter can give you a whole new range of colourful manipulation to your sound design.
Dark Matter offers up a serious amount of sonic possibility for your Eurorack. It works by exciting the audio in your signal flow to provide a fresh take on your sounds. The signals can be antagonised to their breaking point, it's perfect for adding a touch of distortion and overdrive to your basses or leads, or just for crushing a signal down for experimental jams. The feedbacks can be fed back into each other. Over and over, and it can all be CV controlled to give your output dynamism.
Big Beats
Using the Dark Matter on your percussion section can add impactful overdrives to your kicks and snares. Turbocharging your drums is perfect for adding aggression to your drums. Tweak the sound of your drums further using the crunchy 2 band EQ. When using Dark Matter on bass lines, you can add ducking effects to the signal to give them EDM friendly dynamism.
Control Everything
The Dark Matter is entirely CV controllable. You can add dynamism to any of the parameters found on the front panel of the Dark Matter. Because of this, you have lots of patching options and means Dark Matter has a very playable design. It's great for live and because of its versatility, you'll want to use it in every patch.
