• Feedback capabilities: Integrate feedback loops into the audio chain to produce a variety of chaotic noise sounds.

The app offers 20 blocks for audio processing, including:

• Sine generator with basic oscillator features
• Saw and square oscillators
• Signal multiplier
• Delay
• Frequency shifter
• Envelope follower
• “Lorenz attractor”
• Quantizer
• Sample-and-hold
• Reverb
• Special lowpass filter
• Clipper
• Nonlinear shaper for self-oscillating circuits
• Two waveshaping modules for distortion effects (fold and wrap)

In addition, there are blocks for audio file manipulation:

• Lookup table: Upload up to 10 seconds of an audio file for use as a nonlinear transfer function
• Players with/without interpolation and speed control
• "Scrub" block for semi-random granular file playback

The app also features a built-in audio recorder to share files with other applications or through AudioShare, MIDI support allowing users to assign MIDI controllers, and compatibility with Audiobus for streaming live audio to other compatible apps. It supports network MIDI, virtual MIDI in, Audiobus state saving, Inter-App Audio support, and background audio support when connected to Audiobus.
