Thanks, this is brilliant to have to hand and I'm going to work my way through them over the coming weeks. Do you know of an auv3 app that turns your acoustic guitar into a bass guitar? Amplitube has one but that is IAA only.
@scottchenery
I use an electric guitar but I think the following should still work for you if amplitube does:
Tonestack Pro and Overloud THU both support auv3, and have pitch shifter and bass pedals, plus bass amps, though I forget whether any of those are available in the free versions.
Bandshift does pitch shifting.
Also you can use Midi Guitar 2 to convert audio notes into midi in realtime and then trigger midi bass in Garageband.
I don't think any of these sound as natural as pitch shifting with loopy pro, but unfortunately I don't think there's a way to use that feature in realtime, only during playback! @Michael is that correct?
@s6mike
Yep, yep and yep
Great list thanks!
For pitch shifting I can recommend Eventide QVox. Good features and doesn’t use too much cpu. (I own a Micro POG as well but planning to sell it because for simple guitar to bass conversion the app is fine.)
Thanks @Bnjiman, I’ll check it out.
Been using the pitch shift in Loopy Pro and the quality is excellent, just would be great to have it in real-time as you play. Might not be technically possible.
I’m new to loopypro. How do I get these suggested effects into the loopypro app?
After you've downloaded them, you'll find them in Loopy pro's mixer section by hitting the + symbols to add effects, both pre- and post-fader
Maybe check out Nembrini Quinta
Dedicated octaver app
Not an effect, but Nembrini Tuner is pretty nice, especially when paired with MIDI control to pop it up/down as needed. I even set an additional binding to enable it's mute button when toggled. Saved me a spot on the pedal board!
