Hi!
For synced recording, you can use the ML Trigger Buffer module. One input will be the clock you want to sync to (clock divisions, for example), and another input will be the trigger to start\stop recording.
For Midi looping, you can use various audio loopers to record CV. For example, Simpliciter from nysthi will record CV, and even the Lilac Looper, so you can use them to record CV, which is actually the Midi signal. One input for pitch, and another for gates.
