New iOS App, Super J8, ‘Sounds Like A $30,000 Synthesizer’
Developer Matthew Fecher (AudioKit Pro) shared this introduction to Super J8, a new iOS software synth that’s designed to sound like a $30,000 Roland Jupiter-8.
Fecher says that Super J8 was developed in part with the use of ‘ethical AI machine learning’. The oscillators were trained by recording hours of output from a vintage Jupiter-8. The mountains of data gathered by analyzing the hardware synth ‘powers’ the oscillators in the app, creating analog-like variations in the tuning and other attributes that he says make the synth feel ‘alive’.
Other highlights include Oscillator Sync, Cross-Modulation, 2x Oversampling, True Per-Voice Poly Unison, PWM, Analog Voice Modeling, Analog Panning, Envelope Polarity, and Single-Note Polyphony.
