Filterstep

Awesome idea, great UI. Needs a filter frequency control however! The range is not enough, as you can't move the base frequency the range modulates. It's a basic feature really. Also would be great to have more filter shapes. Formant and notch particularly - would sound so good!! 🙏 Great plugin otherwise!

As other people have noted in their reviews, the UI of this plugin is extremely tiny when used as a plugin in GarageBand. That really reduces its usability a LOT. I’m already on as large a screen as one can get on iOS: iPad Pro 12.9”. Also, the inactive controls look disabled. Try a different look, because it’s not fun to assume a control is unavailable when it’s merely unselected. UI conventions exist for a reason. It is a free app, so, thanks I guess? I’m not sure I will be able to make use of it because of the UI, though. UPDATE: The developer suggested resizing the plugin in GarageBand there is NO SUCH such facility to do so. If there is, they seriously need to document it on their app page!

Nearly unusable as a plugin in AUM.

It’s a wonderful tool for creating really unique sequences and sounds - I can even use it for custom sidechain but with my fingers on more buttons, which is great - but it lacks full screen view for GarageBand. Thus, the UI is tiny... usable, but very tiny.
