Reco...I too have used a little casio for percussion..I even used it to get a caliope - like sound on a half-ass country song I wrote for an aspiring really young female. She loved the song, her parents ran out of money and got divorced and she still has my demo wherever she is..My point is, by all means, use whatever you have, but scrimp,save, connive or whatever and try to upgrade your percussion. I still use some built-in stuff on one of my keyboards, that I can control, but I add some stuff with a drum machine too, to relieve the same ol' same ol' beat. You write well and your guitar work is really good. IMHO, tho, I'd like to hear your vocals above the overall volume in all your songs...maybe that's just the often rejected songwriter in me, but if lyrics are written, they need to be heard...seems to make the whole thing come together as you probably heard it in your own head...you did good.....gibs
