Do I have to buy all six?
No. Every effect is a separate app. The bundle is there if you want the whole rack.
Where can I use them?
In any AUv3 host on iPad, iPhone and Mac, such as GarageBand, Logic Pro and AUM, or as a standalone app.
Is it a subscription?
No. One purchase per app, or one for the bundle. No account, no ads.
What does the live display show?
Each effect draws what it is doing: the crushed waveform, the filter curve, the repeats, the reverb tail, the compression curve.
When are they out, and what will they cost?
The effects are coming to the App Store soon. Leave your email above and we'll tell you on launch day, with the prices.
