Living in shitty flats with crappy walls, you cant really get away with practising any instruments which dont use headphones.
Even tapping on midi drumpads while using headphones can be too loud for long daily ( and nightly ) practise sessions.
Also if you want to travel to another place to get away from it all you cant really practise guitar, drums or any instrument that makes a sound in a hotel room either. It just makes too much noise. Plus, while travelling you need an instrument that is lightweight and portable.
Of course, you can always use a laptop with renoise ( if your keyboard and mouse are not too loud and clicky ) or a tablet or PDA with sunvox or milkytracker, those things are silent to use. But for live useage, which instruments can be practised in near total silence?
Does anyone know of any silent practise instruments for live useage?
So far I think the best I have seen are:
Good ol’ midi keyboard
Chromatic midi harmonica
Theremin ( but you cant rock out and move around without changing the pitch while playing, so you might look like a dweeb when you perform )
