Oh, yeah, if you try to do exactly as the keyboard in the video, you need to be sure that the green button is at the same note for all the instruments. I suggest that you add in a TripleOsc instrument, if you then press the Y button on your (QWERTY) keyboard (most common English keyboard), it will play an A. If you then open another instrument in your project and press Y, it should also play an A, or else the green note must be moved! When every instrument play an A on pressing Y, you should be able to follow the videos.
Thank you, I was wondering if moving the green button was one of the things I needed, but did not had a clue on were to move it to.
I have been reading a lot about scales, keys, but then, when back behind LMMS I am lost.
I am getting close though.
