SpringSound vs ToneGen PlusMinus

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: http://www.youtube.com/watch?v=L1GF7HkSV9c and https://www.youtube.com/watch?v=gdYuZ07nmRo And an audio demo of some presets: https://soundcloud.com/christophe-duquesne/demopresetspringsound 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 (www.hakenaudio.com) 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.

Signal generator for identifying audio frequencies by manually matching the pitch. Identifying feedback frequencies rapidly and precisely as an audio tech in a concert situation is a crucial function. Sometimes the feedback is intermittent, or only happens for an instant. For decades I and others have used the procedure of holding a heard pitch in my head and them matching it with some sort of tone generator. There are several iPhone apps that I have used, holding the phone up to my ear to hear the tone. They all have either a dial or a slider to set the pitch. An endless dial can be very precise, but is difficult to operate without looking at the screen. A slider is resolution limited by the length on the screen and so can't be precise. ToneGen PlusMinus uses a novel pitch setting UI which I invented 20 years ago for a Palm III app I wrote. It is very easy to rapidly and precisely match a frequency across it's range of 30 Hz to 10 kHz, without looking at the screen at all. The farther up or down from center your touch slides, the faster the pitch changes. Slide back to center and it stays stable.
