i am using magix cleaning lab 15. i just edited my instrumental and got ready to record. When i recorded my verse i couldent figure out how to mix it in with the song. and also how do i hear the instrumental when recording because im trying to be on beat?
you might consider it is the sound card setting you need to look into. the app records what the sound card allows.
In order to play back audio the same time you record an input you can set the sound card to record "what you hear" meaning it can record all inputs enabled the same time it has audio playing from another application.
To record only the audio input while you play audio to the speakers or headphones you need to set the recording feature of the sound card to just the input you want. These are windows features avaiable with any decent audio interface.
