Module News

Erogenous Tones has entered the Visual Synthesis Eurorack Space, introducing our new prototype STRUCTURE!

The rumors are true, we’ve been hard at work designing a new visual synthesis module that we were able to show the first prototype at KnobCon 2017.  We’ve been marching forward towards a production version, and we’ll be showing the latest changes to the prototype software at Machines in Music coming up in October in 2017.

While we’ve not announced all the exact features, we can say that the final version will be wider than the prototype containing an additional screen and quite a few more buttons.  In addition, we’ve added MIDI controller (class compliant) support as well.  We are really excited about the possibilities this module adds to the visual synthesis eurorack space.

In addition, we’ve been working closely with LXZ Industries collaborating on bringing more technologies to the visual design space.  We are hoping to have this module shipping in the first quarter of next year.

Structure will absolutely be firmware updatable, allow user content, and we are working on building a community around the use and/or design of the system!


Now shipping is our expander for RADAR adding a whole host of new features, like; envelope inversion, ignore triggers, envelope sequencing, envelope delay, envelope roll, level, shape and attack, decay or both swapping, equal/opposite swapping, 8 preset locations, CV recall, and a full suite of random functions!

Now shipping our next high density module RADAR is now available,  8 channels of AD/AR envelopes selectable between logarithmic, linear, andexponential, with CV control.  Also has two other modes providing one or two quadrature envelope sets, or one octal envelope set!  Expander named BLIP coming soon!




Now shipping  Our high density Octal VCA is now available, includes level and offset controls for CV input.  Offset control allows negative or positive offset.  Channels 4 and 8 can be used to as sub-mix for the preceding 3 channels if desired.






Our flexible utility module designed for high density.  8 Channels of attenuation or gain up to 2x.  4 channels allow inversion of the incoming signal.  Bi-colored LED indicates polarity of the outgoing signal.  2 mix switches that allow for 4 combinations of mixing.  Non patched inputs become a DC source that can be used for a variety of applications!






Released in collaboration with SSF, GateStorm is shipping! Advanced eurorack gate generator, has lots of amazing features.  Simple and complex gate generation, logic, randomization, patch changes, full CV matrix, clock sync, output assign, trigger assigns, the list goes on and on.






Utility Module for use with Mother32.  Add’s a variety of useful features like CV control of the patch/bank settings that can be used stand alone or with a sequencer to sequence your sequencers.  Also includes CV control of the ASSIGN output, toggling of the sustain feature of the M32 internal sequencer, and finally an analog sample and hold circuit!

Connects to the Mother32 with a MIDI cable.

GateStorm – Advanced Eurorack Generator [Prototype]

Finally, after a year and a half of development in conjunction with SSF, it’s time to announce our first module, GateStorm. You can check out the fully functional prototype at KnobCon this year, I will be sharing a table with SSF.

There will probably be a few hardware/software tweaks on the final production version, however, you can try out all the features as everything is fully developed.
