Synthesis Engine 

• Supports recording audio inputs and outputs directly to SD card for instant wavetable / sample creation or recording of live performances without the need for external software 
• Supports loading your own WAV files into the Wavetable Oscillator and Sampler software modules, via the SD card (limited only by SD card size / RAM size) 
• Coarse and Fine frequency controls on all Oscillators 
• Comes with a set of 100+ pre-recorded samples / wavetables 
• Storage and Recall of Presets and Settings with the press of a button 
• Rule-based fast 2D patching 
• Supports routing / mixing multiple inputs to multiple software modules 
• Supports routing / mixing multiple software modules to multiple outputs
