Just like cooking, we need trial and error to perfect a recipe. I am not great in cooking but with experienced sometimes my food tastes better. I am so glad that my family survived my cooking, so far they are not starving.
Just like if you are performer, you need the mixing and mastering before sticking to the perfect note and music you wanted. It will take many hours of practicing but I know that your effort is worth in the end. Creating the perfect music with this accessory is a heaven-sent for any musician professional or amateur.
