I have read several threads (see, e.g. Why might one want to record a drum accompaniment electronically without using regular or electronic drumheads and cymbals to drum on?) about creating a drumline using software. How does one go about that? I have seen software where one can input notes by clicking with the mouse, creating note values, etc., using a normal computer keyboard; or using a small piano-like (musical) keyboard connected to the computer. Once the tune is inputted, then you can choose a playback feature.
I can't imagine that's the procedure used for creating a drum part.
So how is it done, and what software do people use for that? I'm just curious. I'm sure my son would find it intriguing, but I do NOT want to steer him away from playing his acoustic drumset! It is very therapeutic for him. (He has Tourette Syndrome and sensory integration disorder.)
