Mod271 modular software for synthesis

Take the modular, patchable sound-making capabilities of Reaktor and (at the other end of the scale) Reason, and combine it with a graphical, zoomable, nodal interface with patch cords showing actual signal, as on the reacTable interactive table interface, and you should get something like Mod271. (Pronounced “mode.”)

The software is in pre-pre-alpha phase, but it’s freely downloadable for Windows users if you’re adventurous, and the developer promises more progress and other operating systems soon.


  • ASIO/MIDI support, VSTi version coming
  • Everything is full audio-rate, meaning you can mix and match MIDI and DSP
  • Powerful nodes: “every node can be automated with unlimited control points and automation takes place right in the 3D environment.” … “nodes can influence any amount of other nodes or switched into a singular state.”, with radial and linear modes for the nodes
  • Interface is 3D hardware-accelerated, and the signals even (optionally) draw at audio rate for realistic previews
  • sample-accurate envelopes and motion, “meaning you can make an oscillator out of an envelope.”
  • 25 node types and growing
  • Make your own nodes with Python

Crazy stuff! It’ll be interesting to see how this one develops. And I hope the Reaktor developers are paying close attention; there’s a lot here that could inspire a future Reaktor version.

Thanks to Ronnie of for the tip!

    "there’s a lot here that could inspire a future Reaktor version"

    Hmm… not sure about that. In what is this better than a more traditional modular software?

    This type of interface certainly made sense with the reacTable, but like that… All these animations also hit the CPU.

  • Don't get me wrong, this is pre-alpha software with a few objects. But here are some things I could imagine making sense in a future version of Reaktor:

    * Visualization of sound at the patching level

    * A zoomable interface (Max 5 of course went this direction, as well, and there were precedents much earlier — but still, a good idea)

    * Easy extensibility (Python here, but there are other options)

    * The ability to do audio-rate MIDI easily

    * Easier control and automation of nodes

    * Sample-accurate envelopes

    Upgrading a tool like Reaktor is a huge, huge job, and that means saying "no" to a lot of things, so this is really just a brainstormed wish list. But let's at least say, what this experiment DOES generate is how much potential there is left in patching, how much can still be done.

    And I agree, the interface itself loses something without the tactile interface of the reacTable. But it's still interesting as a concept, and I respect someone for throwing something out there like this.

    More thoughts on the reacTable soon, having just seen their presentation at the OFFF festival down the street. 🙂

    Wow, this one has a lot of potential. Rendering an interface in 3D isn't very processor intensive if you can offload it all to the video card. Hopefully, he can get this project off the ground.

  • dead_red_eyes

    Wow this looks great! Windows only tho … 🙁

  • disturb

    this is TEH awesome

  • Wow this was very cool…

    I mean i didn't really know what i was doing.. but it was a lot of fun playing notes and moving the nodes around… i assume thats where the ReacTable bit fits??? I could see lotsa potential there… maybe connect it to two nintendo wii controllers and play air hockey with a friend… see how the sound turns out?

    Look forward to a nice working VSTi version!

    Forgive my ignorace – but can you do this sort of stuff in Max or PD?

  • Being a freeware enthusiast, to put it mildly, and owning a touchscreen I'm going to have to give this a try. In fact, the creator posted about it on KVR so I wandered over here to see what ya'll had to say about it.

  • Hey that's my program 🙂 Glad to see it start making rounds!

    In reply to PetitZozo:

    the rendering of the signals can easily be switched off if need be, other than that the rendering of a pretty large scene takes about 1% of the CPU on my laptop (2ghz duo).

    I mean its essentially drawing 2 triangles per node and the texture is already loaded on the card so I can't image a faster way to do it, I'm pretty sure whatever method Reaktor uses to draw its knob and whatnot is MUCH slower!

  • Blank

    This thing looks pretty promising.

    For now it's pretty limited and unpredictable ( a panic button anyone ?) but I see a lot of potential in that work, especially when considering the rise of touch screens in the consumer market.

  • anon

    This has heaps of potential.

    Is it really freeware or is it just free while it's pre-release?

  • Mason

    Good job buddy looking forward to testing it now that im feeling better 🙂

  • On a related note: my wish-list of the things I'd like to see in Reaktor…

    1) Fully optimised FFT, in Core

    2) Lower CPU use (!)

    3) Some more experimental functions (like a version of Absynth's Wave Morph… that has revolutionised my technique since I got it)

    4) Some Core-based vintage synth emulations, there are a few online but there's not much modeling going on

    5) More of those amazingly experimental bundled Ensembles!
