Can EKSS Rack Extensions for Reason Redefine Drum Design?

EKSS Rack Extensions for Reason present a set of custom devices designed for users of the Reason software. Ekssperimental Sounds Studios (EKSS) is a Sweden-based, one-man project created by Erik Karl Stephan Söderberg. EKSS began as a producer moniker and, since 2017, has expanded into a catalog of Rack Extensions for Reason.

The current EKSS product line includes FreakShift, the RDS-16 Drum Sequencer, and DRUMSYN. The RDS-16 Drum Sequencer provides separate trigger and CV outs and can operate with triggers or gates in its steps. FreakShift combines a ring modulator, a Bode-style frequency shifter, an envelope follower and an LFO, and it offers an optional external carrier plus an insert between two engines and routable LFO modulation.

The article describes using EKSS as akin to a boutique hardware maker and characterizes the experience as a rabbit hole that is very engaging for Reason users.

Ekssperimental Sounds Studios (EKSS) is a Sweden-based, one-man project created by Erik Karl Stephan Söderberg. EKSS started as the producer moniker and, since 2017, expanded into a catalog of Rack Extensions for Reason. The expansion into Rack Extensions is presented in the context of the Reason software and its Rack Extension format. Reason 1.0 and ReBirth are referenced in the discussion of EKSS’s historical lineage.

The article highlights FreakShift, the RDS-16 Drum Sequencer, and DRUMSYN as part of EKSS’s product lineup. The RDS-16 Drum Sequencer offers separate trigger and CV outs and can operate with triggers or gates in its steps. FreakShift combines a ring modulator, a Bode-style frequency shifter, an envelope follower and LFO, and includes an optional external carrier plus an insert between two engines and routable LFO modulation. The products are on sale now through the end of June.

The RDS-16 Rack Drum Sequencer includes preset patches and explicit adaptability for multiple contexts, with preset banks aimed at General MIDI devices, Rack Extension drum machines, Reason’s native devices, and dedicated settings for melodic use that employ note-scale options. The device is described in the article as simple but effective and is noted for an intuitive interface; the author characterizes it as “intuitive enough that you might even wonder why Reason Studios didn’t build this as a native device.”

The write-up compares using EKSS devices to working with a particular pedal maker or synth builder, a comparison applied to the RDS-16 that underscores a hands-on, boutique hardware–style workflow rather than a generic, one-size-fits-all software utility.

FreakShift is an EKSS effect that integrates multiple modulation and spectral-processing components into a single device. The effect combines a ring modulator and a Bode-style frequency shifter with an envelope follower and an LFO, allowing dynamic modulation of the processed signal. FreakShift includes an optional external carrier input and an insertion point located between two processing engines, enabling serial routing of effect stages within the device. The LFO within FreakShift is routable, providing modulation assignment options across its internal parameters.

The article describes FreakShift as allowing placement of drive either before or after the main effect path, offering users a choice of pre- or post-processing coloration. The device’s combination of ring modulation, frequency shifting, envelope following and routable LFO is presented as a hybrid of spectral and dynamic modulation tools for sound design. The write-up characterizes FreakShift as a tightly integrated effect that encourages experimental routing and modulation choices. The description presents FreakShift as part of EKSS’s catalog of Rack Extensions for Reason.

It’s a portal into a wonderland of retro-inspired gear, all in Reason.

That boutique hardware feeling, but all in the box.

Using Erik’s stuff is like working with a particular pedal maker or synth builder.

The experience of using EKSS is described as a rabbit hole that is very engaging for Reason users.

This one is a dream: combine a ring modulator, a Bode-style frequency shifter, and an envelope follower and LFO, plus drive before or after the effect.

The RDS-16 is simple, but effective — intuitive enough that you might even wonder why Reason Studios didn’t build this as a native device.

What may not be obvious is that this is adaptable to different devices; there are even preset patches for General MIDI, Rack Extension drum machines, the native Reason stuff, and for melodic use with note scales.

CONCLUSION

The article frames EKSS Rack Extensions for Reason as a boutique, analog-inspired collection of devices that prioritize hands-on, hardware-like interaction for Reason users. It foregrounds technical depth by detailing internal components, routing options and modulation capabilities across devices, presenting those implementation details as central to the appeal. The coverage repeatedly characterizes the user experience as exploratory and engaging, comparing the workflow to diving into a rabbit hole and likening the approach to working with specialized hardware builders or pedal makers. Taken together, the presentation positions EKSS’s Rack Extensions as distinct, technically focused tools with an analog-leaning aesthetic intended to offer Reason users a compact means of accessing retro-inspired, hardware-like sound design within the software environment.
