Due to some things I am not very good at quick time events and had some trouble getting the Karaoke Master achievement. I am probably not the only one out there so I will tell you how I was able to get it, maybe it can help some of you too.

• Turn off any distracting sounds like music etc.
  
• Adjust the headset to a comfortable volume
  
• Click on Karaoke mode
  
• Turn on easy mode
  
• Put calibration settings on 5,00
  
• Choose ASD mode
  
• Select the song: Lost Demon

The song Ripe Fruit would work as well, but you can choose any song you feel comfortable with. I chose Lost Demon because it is calm and relaxing and contains less notes compared to Ripe Fruit. And to be totally honest, I don't know what the calibration settings do, but for myself it seem to work better on 5,00.

• When a note reaches the red line press down all buttons at once, so you don't get confused on which button to press
  
• If you miss or get a good note quit and restart the song
  
• If your hand gets tired switch hands or use both at the same time if comfortable
  
• If you are loosing focus or getting too frustrated take a little break
  
• When done say it out loud: "This achievement is cancer."

I hope this guide made it easier for you. Now do something nice, cuddle your pets or eat a cookie, whatever you feel like doing.

This is the first Guide I made so if you have any improvement ideas or whatever feel free to tell me. Thank you~
