Everyone is failing to see why this is such a dumb thread to start with in the first place. A tool is just a tool get over it. How you use the tool is up to you.
I've played the piano for 11 years now and I have a midi keyboard which I THEN USE TO RECORED THE NOTES I PLAY. Which is simply put, the same as playing a live instrument but with more control. My midi piano also has more sounds then my stand up piano I have in my living room.
Look at it this way. A pencil does not draw your pictures for you or write your essays YOU DO. Photoshop does not draw for you it only HELPS you and aids you to make said image. Your fighting over how someone uses a tool. A tool is just one way to achieve the creativity we have. Some tools are easier then others. You can pick up an instrument just like you can pick up a program, its still completely up to you and your skill to make something GOOD.
A synthesizer can come with presets ok? Did you make your guitar or piano, I believe not you probably bought it from your local store. Hell an electric guitar without an amp is just plain weak does that mean its fake? The way you use this guitar or synthesizer is your skill and your talent along with style. THE MUSIC IS NOT FAKE. Music is a broad subject and your saying that some music is fake which is ignorant. All that differs from person to person is why and how they use their tool to create their music.
So I use a synthesizer to make a piano sound, I can still play a piano in real life (even a violin). I don't need to know how to play it to use it. I can synthesize a guitar to add to my songs because it helps me achieve the sound I want.
Your opinion is yours but you are sheltering yourself so badly its just plain dumb. Open your eyes, do you see the kids using premade loops becoming popular? I have yet to see one track become popular that hasn't had time and effort put into it make it to the top. Yes there has been a few but they were instantly shot down by the people around him/her.
Just decide for yourself. What is music to you? I see music as another way to convey emotional messages or portray a place I've been to or dream of. The list goes on but don't lose sight of why you make music. Most of all make it for yourself.
No music is fake its just made in different ways.
