This might be because I have an older iPhone (4S), but Filtatron doesn’t show up in the FX section of available apps on my phone. Does anyone else have this problem?
It looks like this currently doesn’t work. It doesn’t work for me in iOS 8 on either an iPad Mini or an iPhone 5s. The description of the app says that it can. I love this app as is, but it would be amazing to be able to use this to filter other apps through Audiobus.
Filtatron will not appear in the audiobus fx spot for me also. That’s where I need it
