Primal Audio has released version 1.1 of FM4, a 4-operator synthesizer app for iOS.
Modelled on the popular DX series from the 1980s FM4 provides the same gritty sound, with a modern interface, and without being bound by the limitations of the original units.
Every aspect of the hardware — from envelope curves to sine-table sizes and quantisation errors to digital-to-analogue converters — has been meticulously analysed, in order to recreate the raw and dirty sound of the original units.
Changes in FM4 v1.1
- Audiobus support.
- iOS 7.0.x crash has been fixed.
- Performance boost: the UI responsiveness has been drastically improved.
- App-size has been reduced with more than 60%.
- The manual is up.
