Is a 5 star chip tune master

This is amazing on iPhone, it really is the coolest chip mini lab app I got. Now with full support it is so fun, even the little loop recorder is sweet. Cheers and happy chip creations and beyond.
Hey, with update I’m having basic midi issue. Just note trigger, and if it helps square synth version 1 midi has always worked better than 2. I mean that with respect and maybe others experience this? Cheers mate

Only one concern

I really like this app’s sound, and the interface is really straightforward and easy to read! My only concern is that the polyphony is really limited and a lot of the keys cut off when I’m trying to make a composition. Hopefully this is something that can be improved upon but it’s a great app regardless

Great app! But a few problems with Audiobus...

I love the preset synths and basic UI with its own customizability. But when trying to use it on audiobus to connect to any midi device or FL Studio it blanked pretty hard only giving me one tone of sound and consistently hitting that key until I reset the app. I would really hope that this gets fixed soon because I want to use this in my music!
