Not suitable for advertised use case

In theory, it’s a well-made app with a sensible layout and good workflow. However, it does not work well for any non-trivial synthesizer sound as sampling runs with few seconds per note and more than a few notes and velocity layers will fail with an error message. The developer confirmed that it is a known problem but has not done anything to fix it.

Just needs an update on the timing aspect for 5stars

I would like the issue of the timing with auto recording to be fixed. That’s my main concern. Just simply auto record the notes exactly when key is pressed and stop recording once done, and that’s all. Every recording session something’s always wrong with the samples. It’s still worth 4stars, not bad. Adding an Auv3 fx host to a future update will be a bonus.

Please update

Anyway you can fix or update this app. It’s awesome but I’m getting tired of it stoping every time I record. It’s like a luck game anymore, press record and hope it finishes the process. Very frustrating.

Useless

Pass on this and get AudioLayer instead.
The developer has admittedly abandoned this from what I’ve read on the Audiobus forums, whined about people leaving bad reviews. Don’t want bad reviews? Make a product that works, not a beta with paying customers as guinea pigs .

Very nice

Great Autosample on the iPad (or iPhone).

Easy to setup and use. Exports standard wav (orAIFF, CAF) and the definition SFZ file together to be used in sample library players.

If you have many iOS synths and want to use your own created sounds in a soundlibrary, this is it!
For instance in Audiolayer on iOS, which I am using.
Or use them in your PC/ Mac DAW Sample library player!
