It’s not specific to Model:Samples but I think WavePad will be useful as a general Android phone based “field recorder” that incorporates basic editing and some effects without adverts for $.99. The full version is $10 but I’ll stick with the basic version until I’ve used it a bit.
I particularly like that I can email the file directly from the app.
Are there any Android apps that can directly transfer files to the Model:Samples from my phone via the USB ports?
I tried this out when I got my Model Samples and it worked on my phone. Just be especially mindful of where you’re sending the files while you do it since moving around files seemed less straightforward than in Transfer.
