To extract your vocals with Knockout you might be able to withdraw the vocals or sounds out of a beat, it’s easy as following this structure to make knockout functional on a beat and an instrumental.
You might need basic things to start up.
By setup, you don’t need many preset changes but you might need to set Instrumental to the right channel by changing the pan to right and then sending the sound to a new insert where you put knockout.
Then the beat to be left panned and sent to the same insert as insert 7 in the picture.
You can center the sound by the blue colored knob around the volume knob.
Remember to not send Instrumental and Beat to master by the connection to master.
You can then send insert 7 into insert 8 and record with Edison or record in the Master your recording with Edison.
When you have done a recording of the vocal, you can edit the vocal with Edison and in this track, we have found recording having more instrumental sound so we used denoise process which you can learn here:
Remember to not denoise at a high level. 5-8 is a good denoising level and you need to do this process multiple times.
TIP: You can sometimes cut instrumental up in more parts and make it sound as instrumental to extract just vocals out of the beat. Just send the instrumental layered multiple to the proper right panning and you might end up at extracting just the vocals. It’s not simple and often some sounds might not disappear. But for a DIY acapella it’s most often the only solution if you find just a few seconds of instrumental.
