Don’t be put off by terrible example tracks ...
App itself is mostly fine (particularly at this price) but some of the supplied tracks/loops sound like they were recorded on a slow night at the local karaoke bar ... My (uninvited) advice to the developer: 1) start again with example content (royalty-free loops maybe?) - you really aren’t doing yourself any favours with the current vocals (sorry) 2) reconsider the novelty FX - I can’t think of any examples where anyone would want to add FX to a finished track or even a training loop - you’d be putting effects on the instrument you were playing live - never on the backing track. 3) focus your efforts on improving the pitch change algorithm - this is a useful feature but l get lots of audio glitches even on a modern iPad Pro 4) starting/stopping the audio via cable connected midi devices as well as Bluetooth midi would open up using this app with other pedals (iRig stomp, HX stomp etc) 5) Open up import from Dropbox/Google Drive. Whole tracks may be on iTunes but loops/jams almost never are (so this is particularly an issue for your other scales app) Some good potential here but some fixes and content required - very happy to revisit this score/review if the app is improved.
