yup, I've been using the Yamaha MSP5 monitors ever since I started, got them used from a local studio.
The DIY e-drum.... I bought a set of practise pads and convert them to e-drum... can find the info easily in the web... I trigger the drums with an old Yamaha DD50 e-drum... works quite well... not so sensitive though... will upgrade with a good drum module one day....
