Re: Trying to put a module into my Yamaha DD-65 e-drum kit
The DTX-500 and DTX-502 do not have MIDI in. Surprisingly your DD-65 has a MIDI out but the least expensive Yamaha module that has a MIDI in is the wonderful, but expensive DTX-700.
I am assuming you are on a tight budget, and that is the only reason you are putting up with the DD-65 which is essentially a toy. Your least expensive route, assuming you have a computer, might be to get a MIDI-USB interface cable and trigger VSTs on your computer.
But if you want to enjoy drumming a bit more, get a Yamaha kit, or a DTX-Multi12 plus pedals, which are real gear for musicians. The DD-65 is not designed as a serious instrument.
