As a keyboard player I hate most tracks that you can buy You feel stupid playing a long with tracks that have everything covered. I put my own together so that at least you can play and create. Once in a while I'll put in a horn or string part that's necessary but generally I concentrate on drums and thick bass. I have everything from Jill Scott, Jeff Lorber, Al Green, Alex Bugnon, George Duke, Michael McDonald.......etc. Its hard enough mentally to play with tracks let alone when there's no space. I started this way back when when it was still new. Now it's everywhere . I guess as musicians we can blame ourselves for this. I'll send a sample to someone if you want. I also don't limit the sequences to the top. It sounds better to get a thicker sound by letting your PA create the volume
