What's the audio latency?
Round-trip audio on a LAN is about 15–25 ms (host interface + Remio + client output). Fine for mixing, arrangement, vocal comping and edit work — not for live monitoring while tracking. For tracking, the artist sits at the studio Mac and monitors through the host interface directly. Mix and arrangement work over Remio is comfortable for hours.
Does MIDI work from a remote keyboard?
Not yet — Remio forwards the full keyboard, mouse and trackpad today; MIDI passthrough is not part of the pipeline. Keep controllers plugged into the studio Mac, or pair Remio with macOS's built-in Network MIDI (rtpMIDI) when you need to play remotely — Remio gives you the screen, the audio and full session control around it.
Will my plugins (UAD, Waves, Slate) keep working?
Yes. Every plugin installed on the studio Mac continues to work — Remio doesn't touch the plugin chain. UAD with Apollo or Satellite, Waves licences (USB or cloud), Slate iLok, NI Komplete — all stay on the studio machine. The iPad doesn't need any of these installed.
Does sample rate matter?
Remio's audio path is 48 kHz native. 44.1 kHz sessions resample at the host the same as previewing a 44.1 session through 48 kHz monitoring. 88.2 / 96 / 192 kHz sessions play back at full quality on the host; the streamed monitor mix is resampled to 48 kHz.
Can I record from the iPad mic?
Not today — Remio streams your studio Mac's system audio to the client in sync with the screen, but the client's microphone isn't forwarded to the host as an input device. For scratch vocals or talkback, use the Mac's built-in mic or plug a real microphone into the host's interface directly.
Will my UAD Apollo or other interface work?
The interface stays plugged into the host studio Mac — that's where it does its work. UAD Apollo, RME Babyface, Apogee Duet, MOTU UltraLite all continue to drive the host's audio routing. The streamed monitor mix is post-interface (after the Unison preamps, after the DSP plugin chain) — you hear exactly what the studio monitors would be playing.
