XTRTN 1.3 - Jellyfish Eon is here:

  • Fancy new screws in random colours.
  • Mesoglea controller/polyphonic-s&h module (manual).
  • Mesohyl controller module (manual).
  • Heraldry blank module (yeah this has a manual too - I don’t know why).
  • Improved guides that actually explain what modules do.
  • Started giving the versions stupid names.

Basically, the story behind everything here is that I was annoyed at having to link my controllers and mutes up to s&h modules by hand (especially when doing something big and polyphonic). Mesohyl has knob controls with built-in Sample and Hold options. Mesoglea does something similar with gates; but also A LOT MORE: each gate may be automatically flipped or even converted into a muted/unmuted audio-signal. Mesoglea is a bit complicated, so check the guides linked above.

The blank brand-module is just there so I can look cool and desirable online. “Woah! XTRTN clogged up my library with another useless blank module! They must be important!”

I love the look of these

XTRTN 1.3.2 adds a new module, Mesoglea2.
Very easy to use flippable gates/mutes with fancy S&H synchronisation. No polyphony needed, just link the outputs directly to where they’re needed.
This module is not a direct replacement for the original Mesoglea, but it is much easier to use and should probably be used instead in 90% of cases. Mesoglea+Mesohyl were supposed to be like twin-modules, and I think that comes across a lot better with Mesoglea II.

Somebody, please show me how it works. Just a simple .VCV …

Never posted a .vcv before so hope this works: MesogleaDemo.vcv (8.3 KB)
Mesoglea2 has 5 buttons. The top three will turn the drums on or off (to demonstrate the muting). The bottom two will enable the multipliers on Mononeura (to demonstrate the gate-outputs). It will only update on every 4th beat (as it is connected to the /4 output on the JW Clock).


This is probably the wrong place to ask, but could you please tell me the concept that is used to create the sequences in Hallucigenia? I just want to know out of curiosity to be able to explain it to my friends beyond saying it’s “random”. It’s clearly more than strictly random to me… Am I right? :wink: I just recorded something with two of these. I will put it on youtube soon. Thanks for making these modules!


I… ermmm… I still cannot think of any way to respond to this without disappointing you, so let’s just say it’s the worm thinking for itself! :stuck_out_tongue_closed_eyes:

Alternatively you can say that a spiritually strong digital bug with extended “chi” was coded into Hallucigenia to transcendently change the sequences.



Well whatever it is, I just call it beautiful… :slight_smile:
