What is 2XB303 Acid Bass Loop Maker?
Current Momentum
v4.2
Fixed a bug introduced in last version that messed up the loop recording on some phones that also messed up the UI connections. (Sorry bout that!) Also, as this app was released before Apple's IOS files app was introduced, it used an old system of iTunes file sharing. That has now been removed and instead your loops can be all saved in 2XB303 iOS Files folder, also incrementally the Export section . You can keep them stored in there for later if you have a nice sounding loop you want to keep. You can access them in iOS Files to copy , paste , rename etc. Also fixed some other bugs
