@livv94 as this is a duplicate, please monitor the original issue here: 0000501

That issue from 2014 appears to be about bouncing audio from within OpenMPT, or recording playback as a sample/combining samples that have been already loaded. This issue is about recording audio from a microphone, Line In, or loopback. Am I reading the other issue incorrectly?

Yes, the other issue is specifically about recording from external inputs. OpenMPT can already bounce tracks to sample slots through stream export.

I do not think this is necessarily a duplicate of 0000501 (which primarily talks about recordings stems, mostly during playback).

It's a duplicate of https://forum.openmpt.org/index.php?topic=6161 (which I also initially missed).

I guess we can keep this one open. I'll rename both to try to better distinguish between them.

In particular, this issue requires somewhat separating audio input logic from audio playback logic (i.e. separately opening an input device solely for the purpose of recording a specific sample right now) , while live stem recording during playback requires them to be tightly integrated (i.e. using the exact same Audio IO stream for both).

This might well even end up in totally separate code paths, and both are really also separate workflows, as far as I can see.
