If you’re the kind of person that draws disapproving looks from fellow commuters as you drum away on surrounding objects, Korg’s Wavedrum Mini is made for you. Mind you, it won’t be any more subtle. Strap this little beauty to your knee and tap away with over 100 different sounds ranging from percussion to synth tones. Other extras include built-in speakers, pre-set rhythms, overdub and an included sensor which turns objects into instruments. Check out the demo for a full list of features then pick one up for around £260. Go on, you know you want to.
