How are we to answer this question? You've told us absolutely nothing other than it's a "cheapo Yamaha keyboard".
Some useful information would be...which model of Yamaha keyboard is it, exactly how do you have it connected to your computer, and what exactly have you done so far to try to use it?
I’ve been trying to get it into the PC via Tascam US-122 mk 2 (midi to USB) (very noisy unit) Once I go to program settings and set the ASIO driver to the Tascam - then it changes the "Audio Playback" to the Tascam - and as noisy as it is I get audio from the "phones" out on the tascam.
However - I still cant get the Yamaha to trigger the sounds in the MM 2014 program
I also have a simple Midi to USB converter - USB on one end - and "In & Out" on the other - it does have 3 lights on it - "Midi - Out - In - the only light that lights up is the "In"
