User reviews

Not working well.

I go to share the file I made in the app and it crashes whatever I am sending it to.

Response from developer

Thank you for the feedback! If you're talking about the .fieldkit file, those can only be opened within FIELD KIT and aren't compatible with any other platform. FIELD KIT does support audio export as a .WAV and you should be able to use that audio in any other DAW or host.

Useful and funny to play with it

I quite like the app. So far, though, I’m still in the "trying things out and learning" phase. Is it possible to zoom in on the waveform? Unfortunately, that doesn't work for me on a 17 Pro running the latest iOS 27.

Worth Every Penny

Great app. Well engineered. Easy to learn. Check the live stream on YT if you’re stuck. Works well in Audiobus.
Suggest 5 lfo’s - there are 5 targets and space in the patchbay.
Otherwise well done.

Terrific audio playground

Really great idea: bring up to four audio recordings/samples into the app, then cut/dice/loop/edit them to make a soundscape. You get control over playback speed and direction, volume/pan etc, plus there's a really great section where you can use an LFO to control the parameters during playback so you can get nice auto-panning, flutter effects and so on.

Two things missing: no ability to add AUv3 effects to the four channels. This is a big one for me and it limits what I can do to create ambient effects. You can load it in AUM but then the effects you add would be global across all four slots. Second: no ability to record and capture audio within the app, so you can't capture a space spontaneously out in the field. Bizarrely there's a record button in the app but it doesn't record, it just exports your current audio.

Response from developer

Thank you so much for purchasing and for support! Multi-out windows will be available in the next update, so you'll be able to route each playback window to its own audio channel in any AUv3 host for further processing of each window. As for internal audio recording, that is a really neat idea and something I think would make a lot of sense down the road! Thanks again for the feedback.

First App - Fantastic

First app from this developer and it’s a sound designer’s dream sample manipulation tool. I’ve spent hours with this and it continues to impress me.
