Alien Box is a completely new kind of audio effect that you have never heard before. It makes the sound big and slightly increases the sustain while adding gentle vibes to it. The vibes are LFO modulated and the effect is using very complex resonator system inside. It is modulation effect and you can compare it to flanger, phaser or chorus but it is not like any of them… The app is an Audio Unit Effect AUV3 and can be used inside GarageBand or other AU host apps as an effect plug-in. Alien Box can also run as a stand alone app adding effect to the audio input so you can play your guitar, bass or synth directly three the app if you have the connector to do so. Alien Box controls: - Gain - you can use it increase the gain and sustain - Vibe - main tone and background vibes balance - Depth - controls the modulations depth - Reverb - adds reverb to the background vibes

CrushStation is an overdrive/distortion effects plug-in with controls that drive your tone anywhere from a creamy saturation to a brutal sonic assault, with everything in between. Originally from the Eventide H9 Harmonizer pedal, CrushStation has been refined for experimentation on numerous sound sources from your iPhone or iPad. Crush some octaves into the mix, or turn up the Sag to bring the whole sound to its knees. An added bonus, CrushStation is a true stereo distortion. CrushStation is an extremely versatile plugin, capable of adding spice and flair to a variety of production styles. Perfect for drum dirt, the Grit control adds preamp-style distortion that can help bring out kicks in the mix. Vocals benefit from the subtle distortion along with lower octaves for unique pitch blending effects. Further fine tune your sound using the three-band EQ which can help tame cymbals and vocal sibilance. Sure it rips for guitars and basses, but when you need a little warmth and saturation, add gusto to any synth. Features: - DRIVE ranges from subtle boost/overdrive to full on distortion with GRIT and SUSTAIN controls to push it into fuzz territory. - Unique SAG control - inspired by the result of power rail sag of dying analog gear - produces sputtering, crushed, and broken sounds. - Mix in lower and higher pitch-shifted OCTAVES, pre-distortion and compression. - GRIT creates low-end, gritty, chugging sounds. - Individual EQ controls to perfectly craft your tone, emphasize harmonics, or punch through the mix. - GATE your signal for taming the output of the distortion OR combine high threshold gating with MIX for parallel gated crunch. - The performance RIBBON provides real time, dynamic and fluid control to morph back and forth between the settings of your choice. - HOTSWITCH allows you to switch between two different distinct settings within the same preset at the push of a button. - Mixlock keeps the MIX constant so you can easily audition presets. - Available as an Audio Units AUv3 plug-in and Standalone App.
