As I said, I got this idea before I saw drumagination (and I saw it on vdrums long ago). But, sure, it`s good you posted it.
My laptop is on the other side of the room. If I`d have a dedicated computer for drumming I`d definitely put it in the kick drum as well.
I`m not using an amplifier, just the headphones. Although, I have some active studio monitors (connected to the presonus 22vsl and the laptop) and I can listen the drums there too ... I rarely do.
I like (and I have) to be quiet
Anyway, just wanted to say this approach gave me more freedom and I can now fine tune the drums much easier, unlike previously. Everything is now under my hands and I`m taking advantage of it.
