How about the little video made by one person's band at present? Do you need multi-channel mixing software besides editing software? It is better to have a detailed explanation.

See if your requirements are high. If your requirements are not high and you just want to combine several musical instruments, you just need to edit the software. You record one instrument first, and don't record the accompaniment when recording the second instrument. Just record a dry sound, add some reverberation, and many instruments are the same. Finally, it is also possible to synthesize with editing software. If you want to hear good sound quality, you need post-mixing. When mixing, all you need is dry sound, so you still use the national karaoke, use the studio mode, pull the accompaniment to 0 after recording, pull the voice to 70%, and finally export it to the mixer, so that the mixer can finally synthesize a high-quality audio for you.
