In need of an update

Things seem to work. The effects do work. But wow, is this thing in need of an upgrade. It looks like it was designed with the iPad first released. Extremely outdated design, with very little manual control over the effects. Good thing there are 50 of them.

Also, it has preset banks (A,B,C,D) but I can assign any of them with the effects I want easy access to. So while I have 50 effects to choose from, I can’t assign them to the banks.

Overall, pretty disappointing.

Surprisingly versatile!

First off: this app works as an AU effect, meaning you can load up multiple instances of it in Audiobus if you want to chain its different effects. (Audiobus is a good bet if you want to record into Garageband, as well - just make GB the output device.)

Beyond that: hey, it's a great (and contained) clearinghouse of studio quality vocal effects! And, even better, it's actually a useful/quirky multi-FX unit no matter what the instrument. The "Hard Tune" Autotune clone does more or less what you expect on vox, but also emphasizes some novel aspects of my MV08 beats; similarly, its various "megaphone" settings can be used to smash an acoustic guitar into "Wish You Were Here" territory, all with the weirdly comforting transparency that marks most of TC's products. It's not the most essential purchase I've ever made - I was already drowning in IAAs and AUs that did most of what it does - but as a pro quality all-in-one vocal lab that does a myriad of things very well, it's well worth the cup of coffee it costs. Don't believe the poor reviews.

Go to for vocals on GarageBand

As an iOS only music creator, i find the effects invaluable for vocals. Their auto tune clone “hard tune” gives that rich warble that only hard dehumanized pitch correction can do. For softer vocals, they have a pitch assist setting, which is perfect for singers. The presets are great, the sound is polished. Can’t wait to see what they do with it!
