Any Cable Everywhere

ACE belongs to a new generation of synthesizers developed with the latest, fastest computers in mind. ACE offers classic modular synthesis and more at a fraction of the cost of dedicated hardware. But like its hardware forebears, you can patch any output into any input: the number of different ways to connect modules together is practically infinite. Needless to say, you will never run out of cables!


ACE - Any Cable Everywhere: Main UI


The careful selection of modules and clear layout make ACE the ideal instrument for newcomers delving into the fascinating world of modular synthesis. But ACE also delivers the goods: like any medium-sized professional hardware system, ACE has enough synthesis power to keep you discovering new tricks for many years to come!

Key Features

At first glance ACE may seem overly simplistic, but remember that virtually anything can be plugged into anything else. For instance, try plugging an LFO into a Filter, then use that filter as an FM source for an oscillator. Crazy routing is possible, endless fun is guaranteed!

  • semi-modular architecture, with default routing like ARP 2600
  • 25 signal sources, 30+ signal targets
  • up to 8 times unison with +/-2 octave detune range each
  • exceptional filters, can self-oscillate
  • LFOs can be used as VCOs and vice versa
  • sync, FM, cross modulation
  • use multiples for inversion, amp / ring modulation etc.
  • custom LFO waveform "tap map"
  • microtuning (Scala .tun standard)
  • 100% free of Supersaws!
  • 2 x LFO (0Hz - 20kHz)
  • 2 x ADSSR envelopes
  • 2 x VCO (0Hz - 20kHz, PWM, VCO1-linked sub)
  • 2 x VCF (LP1/LP2/LP3/LP4 and HP/BP/BR each)
  • 2 x VCA with pan
  • 2 x multiples (with modulation input)
  • 1 x mixer (for standard sources + aux)
  • 1 x ramp generator (loopable)
  • 1 x mapping generator (up to 128 values)
  • 1 x noise (white, pink)
  • 3 x global effects (chorus, delay, 2 x tone)

ACE in action

Enjoy this funny little video by Urs Heckmann and Jayney Klimek. He Loves My Pies is all about true love for synthesizers! Made with 24 instances of ACE, no other synths were used.

ACE Demo Songs

Here are a few demo song showing off ACE and all it's modular goodness:

New Frontiers

Tasmodia contributes a short synth jam using 11 instances of ACE for all the sounds.

Wet Experience

Urs Heckmann performs a bit of sonic experimentation with ACE.


Einsteigen bitte! DocT takes us on a slow, heavy ride.


Dumb 'n' ACE

A raucous track when ACE meets breakbeats from DocT.


Urs gets inspired by a particular 80s comedy movie.

Cold as ACE

DocT provides a track that swirls and sweeps, moving from ambient and pulsing rhythm.


Patch Sampler

Rob Lee runs through a some ACE factory patches.


ACE Introductory Videos

Watch Dan Worrall's 4-part ACE tutorial Introduction to ACE. Part 1:

There's more: part 2, part 3 and part 4


ACE is very demanding on CPU.

You will only be able to enjoy ACE with a modern, fast computer, and you may learn to appreciate the freeze function in your DAW - Don't say we didn't warn you :-)

Finally – ACE's demo restriction is a mild crackling sound that appears at irregular intervals.
