The hybrid synthesis algorithm on which Addictive Pro is based provides you with efficient means for easy control of complex sounds far beyond usual sound synthesis methods:

Addictive Pro provides you a with unique form of Wavetable oscillators. These Wavetables are generated from the harmonic content and the free digital filter structure entered by the user.

The sound of up to 12 of this Wavetable oscillators is then further refined with a classic analog filter available in several 24dB and 12dB forms.

For the optional noise part of the sound you can use the same sophisticated digital filter struct as for the wavetable oscillators allowing for a vast variety of ever changing noisescapes.

The intelligent sound and rhythm randomizer can be applied to different sound aspects separately for really useful sound design and inspiration.

A four part polyrhythm Arpeggiator creates complex rhythmical structures with a touch of a finger.

Incredibly dumb!

Update: Third time is a charm, as they say. Finally the IAA transport bar has been placed where, when concealed, it no longer covers any area that is needed while actually playing Addictive Pro.

The developer is very responsive, even if it did take three tries at a sensible location for the IAA transport bar. Back to five stars though!

I absolutely love Addictive Pro. I think it's their best app to date. It'll take me a while to get my head around everything Addictive Pro can do and to utilize all it has to offer, which is a lot! Especially the poly-rhythm arpeggiator! I love it!

Ok, I held off on my app review after their initial release where the developer placed the IAA transport bar on top of Wave B tab. I gave them their solution. To put it in the upper left corner and have a tab that expands and conceals it. What do they do? Place it on top of the keyboard range/size adjustment!!!! Yes, they do allow concealing it partially, but it still cover a significant part of it. I am dumb founded how ANYONE can be that DUMB! Does Audiobus own them or something? They do use the tab to expand and conceal Audiobus like I suggested they do for the IAA transport bar. While I love this synth, I'm deleting it and all their other apps I own and moving on. Simply incredible and very sad.

I have problems using this app in iMPC pro 2. It use to load up in the iMPC pro 2 before my locked and restored back to factory settings. What procedure can I use to fix that problem in order for me to use it in iMPC pro 2

Why does it keep quitting?

When I use this app on GarageBand, for some reason it keeps quitting. If you fix this bug again, then I will give it five stars. I like the synths though.
