Physical modeling and remote for the Haken Continuum

SpringSound is a physical-modeling audio synthesizer that produces sounds by simulating interactions and vibrations of a set of activators and masses connected to springs. The model offers detailed control of an array of features including: gravity, bouncing, fluid and static friction, mechanical limits, non-linear functions, and more.
SpringSound is provided with a very large set of sound presets that you can tweak and save.

Small video introductions are available: and
And an audio demo of some presets:

It can be used as a sound generator or as an effect using its Audio-In feature, opening a new world of physical modeled effects. It is fully Audiobus® 2 and inter-app audio compatible, and manage state saving.

SpringSound can be controlled by a standard MIDI keyboard and directly from the iOS device screen. It is complete with the new MIDI MPE (expressive MIDI) and therefore can be controlled by most expressive controllers like the Haken Continuum, ROLI Seaboard, Linnstrument, Madrona Labs Soundplane, etc.

SpringSound app is designed for optimum use with the Haken Continuum ( and integrate an IOS Continuum Remote (iPad only) allowing a very comprehensive and accurate remote control of the Continuum from your iPad (access to all parameters except programming the Eagan Matrix).

SpringSound has be designed to explore sounds domains you won’t be able to access with other synthesis technics. It expands your sonic palette with a new world of physical sounds. It is a rich musical instrument, a sophisticated sound-design tool and an entertaining sonic playground.

SpringSound is the big brother of my former Ackorage-Spring app.

App crashes when activating Bluetooth midi

This is is exactly what I have been looking for except when I click Bluetooth midi, the app crashes. Please fix.

Good Engine for foley FX artist

Great synth with lots of control over engine for natural sound design of springs, metallics, slapstick, FX and things that fly through busy kitchens, or go bump in your utility drawer. It can be used to design foley sound FX or melodic harmonic pads. The interface was a bit unusual at first with the pinballs, but plays a part in the physicality mass and velocity.

Thanks for the 2017 update!

I use it on my iPad Air 2 iOS10.2

Continuumini not responding

I believe I purchased this in error, unfortunately there is no apparent way to connect to a Continuumini as its USB is the wrong type. Ironically it does power up, but no data connectivity. Please cancel my order if possible. Thanks!
