There is no undo/redo in Enso. You also have to be mindful of how you’re using it if you’re planning on decoupling the playback and record rates/directions or you might find yourself wondering where all of the clicks are coming from.
Has LRC5 has been mentioned here yet?
It’s a free and handy parametric EQ. I often just use AUM’s built in filters/EQ for quick adjustments, but it’s nice to have 5 bands of EQ only taking up one effect slot in AUM for carving stuff out of field recordings in an audio player or whatever.
