I freacking waisted my time ### 1/5 — 没内录 *2021-08-30* 没有内录差评 ### 1/5 — 接続認識しない *2021-08-12* UR44をCCモードにしカメラアダプタで接続。UR側はPOWERが点灯になっているがアプリ側で認識マークが点滅。UR44はファームウェアアップデート済み、他のGARAGE BANDなどのアプリで音が入っていてiPhoneにBluetoothイヤホンで入力音をモニター出来たのでiPhoneを経由しているのは間違いない。このアプリ上だけ音が出ない。 ### 1/5 — Please loopback *2021-03-11* Please loopback ### 1/5 — ループバックが… *2021-03-10* UR-Cの方はできるようですが、iOSでの使用時にループバックがON/OFFできません！！(強制的にOFF) 純正カメラアプリなどでstereo2mixで録音できなくてかなり困ります…(LRに振られてしまう) UR-RTシリーズが使い物にならなくなってしまうので、ぜひ更新&実装を早急にお願いします！！ ## Frequently asked questions about dspMixFx ### What is dspMixFx? dspMixFx is an iOS control application designed to work with specific Steinberg UR-series USB audio interfaces.
