Heavy use with varying degrees of success – FM Essential - US Review

I use this app to live record into GarageBand, and it comes in handy for making sound effects. However, just recently I opened the app to discover that the instruments suddenly stop working if you turn off both effect filters in the EFX/EQ module. I used to be able to leave the instruments completely dry so that I could hear the raw sound accurately and make precise adjustments. Now, the program disables instruments completely if the effects are turned off, or even if they’re set to “thru.” I even reinstalled the app and encountered the same problem. Pleas fix this rather serious obstacle.
