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

Read full description

The ERS DimD chorus audio plugin was originally designed and sold by Harrie Munnik and his Dutch company EmptyRoomSystems. DDMF is proud to carry on the legacy by distributing and further developing the set of ERS plugins. This plug-in has been developed to sound like the Roland Dimension D Chorus with enhanced controls (a hardware chorus that has been used on thousands of recordings worldwide). It has its own signature sound: it is famous for delivering a subtle, stereoizing enhancing, airy effect while adding more presence to a sound. Most chorus products give a lot of modulation and do not keep the original structure of the sound intact. This chorus is way more subtle and adds something rather than take away the original quality of the sound.
