so basically I was forced to upgrade my ios to 9.3.5 which there is no exploit for so I'm stuck with Cydia impactor a tool that installs IPA files and signs them for you. I installed korg im1 just to try before i buy and I got no sound. installing other musical apps where fine like audio bus and warldof nave but could not link those apps to beatmaker 2 app for some reason. I'm sure korg figured out I didn't purchase their software I'm just wondering how if I'm not jailbroken lol.
(ps don't tell me to change any audio settings been there done that)
oh and
heres a track ive made with the beatmaker 2 app ...

 

Cydia Impactor forte has supported its iOS integration and requires them to be able to create modules. So I recommend you to download this app. download now

 

Try Sideloadly and Alt Store and see if they works better (no jailbreak needed).
