Vintage iOS Stereo Tremolo FX app! Originally released in 2015, Johnny Mini is a powerful stereo effect for creative rhythmic tremolo effects, independent per channel.

Johnny Mini is a powerful and versatile stereo multiwave tremolo effect designed for Audiobus and Inter-App Audio, perfect for adding everything from classic guitar amp style tremolo to pulsating, rhythmic multiwave modulation effects for guitar, synths, voice and more. Harmonic Tremolo modes create vintage phaser and univibe like tones, you can also modulate the rate of the main LFOs with a second LFO for interesting speed sweep effects.

In addition to Audiobus and Inter-App Audio, Johnny Mini can process external hardware by connecting a professional USB audio interface such as the Apogee Jam or Apogee ONE, and many more compatible USB interfaces. You can also use the built in headset microphone. Guitarists can use the effects live by connecting the output of their audio interface to an amp.

Johnny Mini supports USB MIDI interfaces via the Camera Connection kit, Bluetooth MIDI (iOS 8), Virtual MIDI and WiFi connections. The MIDI Learn function lets you easily assign your MIDI controller's knobs and sliders to control Johnny's effect parameters.
