Noise Engineering has added new Eurorack hardware: Jam Jam 6HP trigger-and-gate with clock phasing and delay, and Quantus Trajecta 10HP quad envelope modules. Plus if you’re using the swappable-function Versio and Legio modules, you can now buy ready-made overlays.

First, the new hardware. These modules are on a different platform than the swappable Versio and Legio modules. But they do look tasty:

Jam Jam

  • 6 HP in silver or black
  • Available now
  • US$240 retail

Jam Jam is trigger-and-gate with four channels, and three modes:

1. random: four independent probability generators

2. clock phase: clock goes in, adjusted or CV-modulated clock goes out

3. gate delay: shifts in timings from sub-ms up to over 15 seconds

We have a lot of fancy modules that do sort of everything and nothing in particular with clocks, triggers, and sequences; this is a bit more focused. You just get ultra-precise timing modulation, and crucially, everything is CV-controllable.

Not to compare apples to oranges too much, but there’s some appeal to this approach over the more computer-like sequencing modules out there, especially as we have, you know, computers. Being able to patch together subtle shifting clock creatively looks compelling – as well as having this on-hand as a utility for tightening up timing or solving timing issues.

  • 10 HP in silver or black

  • US$280 retail

This one’s a quad envelope which Noise Engineering says has polyphonic applications in mind – though it does look equally useful even if you just want more envelope generators around for your monophonic rig.

You’ve got multiple envelope shapes, everything is CV controllable, and there’s an interesting ‘hold’ function to freeze envelopes. There’s also a Tremolo – an LFO with Rate and Wub controls, so maybe not something you expect on a quad envelope. The “polyphonic” part is down to having controls adjust all four envelopes at once.


I actually really like the idea of these swappable-firmware modules letting you make your own overlays, especially since modular is all about customization. But have I personally gotten around to doing that? No, I have not.

So these overlays look handy. They’re priced at $16 each / $36 3-pack (Legio) / $112 8-pack (Versio), but usefully you can just pop them on the module without removing knobs. That means your last-minute idea to change your percussion to a VCO the night of the gig doesn’t have to involve you juggling knob caps during sound check – phew.

These ship direct from Noise Engineering; I’m curious to see if any resellers will pick them up. Otherwise maybe us European Noise Engineering owners here in Berlin should just have a “user group” over at the Zollamt.

Everything is over at Noise Engineering – wait, not that one – this one:
