Robaux SLØP1 is a new hands-on MIDI-only note quantizer and chord creation module for Eurorack, perfect for sequencers and other MIDI gear.
Today’s sequencers and MIDI modules are packed with features. Features like scaling or chord generation are almost always included. However, there was a time when such modules were rather feature-reduced.
Anyone who wants to upgrade their older modules with chords or scales can now look forward. Robaux has released SLØP1, a new easy-to-use utility module that brings these features over MIDI.
Robaux SLØP1
SLØP1 is a new, easy-to-use, hands-on note quantizer and chord creation module for Eurorack. Robaux SLØP1 has 16 push buttons and two modes: chord and scale.
In Chord Mode, each key can be assigned its own chord, which can then be played directly. These chords can be defined entirely freely, and you are not limited to transpositions or fixed progressions. A downer is that you cannot save multiple chord sets in the module.
Then, in scale mode, you can create your own scales and map them directly to the keyboard, perfect for solos. Unlike classic CV quantizers, SLØP1 even works polyphonically. Also, no saving option here.
On the connection side, it has MIDI I/O on TRS-MIDI Type A sockets. Even if we immediately associate CV/gate with Eurorack, the module only has MIDI inputs and outputs. It’s designed to work seamlessly with modern Eurorack sequencers as well as other MIDI gear.
First Impression
At first glance, it seems like a handy tool for quickly scaling notes and creating chords from them. Unfortunately, the feature set is somewhat limited, and I’m missing a function for saving chords—at least five of them.
On the other hand, MIDI connectivity is practical, so you can use it outside the Eurorack world.
Robaux SLØP1 is available now for 99€ (assembled) or as a DIY kit for 75€.

I’m not getting the point of a Eurorack sequencer without cv/gate. Yes, MIDI comes in handy, but MIDI only modules in a Eurorack?
many polyphonic modules use MIDI and sequencers also have MIDI 🙂
Sure, I understand the MIDI part of it. It’s the lack of CV and gate which surprises me.
