Customer Reviews

Excellent, low-memory FX suite for guitar and other instrument apps

Igor's apps have really has a reputation for tight, streamlined programming that runs efficiently even on some of the older devices. There is nothing revolutionary about the effects offered in Master FX, except that they run exceptionally well as an AudioBus effects slot app. With a guitar app in the input slot, I was able to add full compliments of lush reverb and delay, and round out my sound with the equalizer and compression. I also found the large knobs to be touch-screen friendly and easy to use. Finally, I appreciated input and output meters so you can monitor your levels from the app. Another great app from iMusicAlbum.

GET This!

Another Fantastic app from this dev! Very deep yet easy to use. You don't need all the glamor if you're concerned about the way this app "looks". Lots of bang for the $$'s You won't regret the purchase!


I like the other app this dev made very much. That being said, I am a bit disappointed in this one. For the price I would have liked to see More of a variety of unique and unusual effects. I mean this isn't effect intern, or effect apprentice. It's effects master! Let's make it so. Currently it is too similar to the other one.
