Cre8audio Function Junction: A disco party of modular modulation
4,0 / 5,0 | 
Get on your disco pants and head down to the party at the Function Junction where you can dance with envelopes, flirt with functions and drink shots with LFOs.
Function Junction
Big, bold and bristling with possibility, the Function Junction is looking to get the party started with a combination of modulation sources and an unexpectedly groovy mixer. Suppose the Make Noise Maths (with which it shares some functionality) is your nerdy friend who delights you with clever movements in a complex, sensible corner of the room. In that case, Function Junction is your outrageous flatmate who throws themselves into the middle of the party, dances all night and is then sick on your shoes.
I think what I’m trying to say is that multifunction generators can often be complicated, deep and difficult to follow. Cre8audio designed Function Junction to be obvious, fun and thoroughly useful. And for shallow people like myself, that’s a huge relief.
How functional?
With the Function Junction you get an ADSR, a function generator, an LFO and a mixer. They are all independent yet interwoven and sprinkled with just enough modular magic to be more than utilities. Produced in collaboration with Pittsburgh Modular, you know that this will get interesting.

The ADSR seems simple enough, with a knob for each stage and a long and short mode. However, it’s also loopable in an interesting way. The Attack and Decay knobs then set the rise and fall, whereas the Sustain and Release take on the stretchiness of the timing. A CV “Loop Jack” input lets you engage the loop with a pulse, meaning that you can go from smooth enveloping to spontaneous looping at the touch of a pulse.
The Function generator uses an Attack and Decay envelope like the Rise and Fall on Maths. It has a number of modulation modes where you can bring in CV to control the Attack, the Decay or both at the same time, whether looping or not. You can also send it into seizure through the use of the Loop Jack. It all helps produce that weirdly modulated LFO effect that Maths is quietly famous for. There’s also a Sustain for a bit of ASR action, and you can dial in the exact response curve you’d like everything to follow.
The LFO is just that, an LFO with a triangle and square output and a knob. It becomes very useful once you patch it back into the Loop Jack or function modulation input.
Mixer magic
In the mixer section you can find lots of modulation magic. By default, the three previous functions are preset at the three inputs. This gives you an additional ADSR and Function output plus a mix of all three. The attenuverting knobs at the bottom of the module let you dial in and experiment with weird combinations of envelopes and modulated modulations. Plug something else in at the top and it bypasses the internal routing. An alternative output uses OR logic to throw out the current highest voltage from any mixer channels just for fun.
Hanging out at the Junction
All in all, a lot is going on in the Function Junction. But all of it is boldly out on the front, easily accessible and immediately useful. It’s not about sharpening your pencils of deeply considered complex modulations; this is about breaking out the crayons and getting stuck in with playful fascination.
It’s a genuinely helpful module with creative purposes that will be a permanent resident in my rack. Check out my review video below.
Function Junction is available now for $249.
