Euh… 
what are we talking about there ?
An app for what ? To have access to the settings ? To copy some sound to and from the Aeros ? I find the use case pretty small…
I have a Spark Amp too and the app that goes with is very handy to do things offline… Its goal is to help you taylor your sound to something that you like then you copy to one of the 4 slots available on the hardware in order to be able to use the device without any app… The app itself is not meant for the live action.
An app will never help you use the Aeros more easily in a live situation. That’s my first assertion. Learning how to master looping has nothing to do with the device itself.
Now, let’s say you provide a nice use case for an app (and maybe something around the midi setup and connectivity/interaction with other devices is totally valid. As I don’t have any BeatBuddy showing up in my mailbox I didn’t have this need but feel like there’s something probably missing there). I hear you talking about an Ipad thing…
In case a companion app development is decided (and I doubt Singular Sound has the horsepower to do that anytime soon), here are the foundations requirements:
- To be Open Source (like the BBManager is)
- To be multi-platform by design (ie no design choice should be made that would lead to this incompatibility): Windows, MacOS, Linux, Android, IOS
After that we can discuss about the content of that app…
