KQ Dixie is a 6-Operator FM synthesizer that is modeled on the synthesizer which appeared on the 1980s. FM synthesizers make sounds with Frequency Modulation. FM brings rich and brilliant sounds which are impossible to create with analog one. It makes very complex waves with simple modulations. The same method is used for a radio. The synthesizer gained much popularity in the 1980s. This app lets you make sounds freely with 156 voice parameters. Almost all parameters are compatible with DX7. Audio Unit v3 compatible.
