LFO has to modulate a parameter?? LFO overrides knob postition when depth is set to 0, making it impossible to use all of the effect knobs. Reverb algorithms hog cpu other than the "original"

After a looooong time, the app is at last usable! Good work! I have retired my last two stars review. I will give you the last star when I can assess the app, since I haven’t manage to use it so far. Congratulations!

This app is severely let down by its poor user interface design and buggy effects. The tiny icons, unresponsive menus, and unreliable button taps make navigation a frustrating experience. Some of the effects work fine, some got bugs or sound weird, the overall quality of the audio processing is not the best (the reverb is terrible). However, the app has a fantastic concept, and it could be truly excellent if the developers address these major shortcomings through substantial updates and improvements. If they manage to fix the UI, squash the bugs, and enhance the sound quality, this app would be a powerful and useful tool. As it stands now, it's difficult to recommend.
