APG Composer combines a 3-voice FM synthesizer with an implementation of the Logique Analogique sequencer, which triggers notes when a weighted sum of different signals exceeds a threshold. APG Composer was created from a Simulink* model without writing app-specific code, using the Audio Plugin Generator source code. You can obtain both the iPhone / iPod Touch app and the iPad app from the iOS App Store.
Compared to the iPad version of APG Composer, the user interface for the iPhone app has been simplified by controlling several parameters using just one knob. The underlying sound synthesis algorithm however remains the same.
!!!!! Please note that the iPhone app will work only with devices with an Apple A4 processor (or faster) !!!!!
Currently, this includes the iPhone 4, the iPhone 4S, and the 4th generation iPod Touch.
