I just got myself a Yamaha MX61 (I'm not really a keyboard player - just do a little fills during live gigs). Anyway, I found that it doesn't put out a whole lot of sound when directly plugged into my Mackie PA system. I have a Mackie board with powered Alto speakers. Someone recommended that I get a keyboard monitor. My intention is that I get something (monitor or powered speaker to act as monitor) to plug my keyboard into so that I can hear what I'm playing and then daisy chain that speaker (be it monitor or powered speaker) to the Mackie board and out the PA system. Now I already have 3- 12" powered monitors in addition to 2- 15" powered speakers. The bottom line here is that I need a something that I can hear my keyboard and also get out the PA system to the audience. We play hard classic rock in relatively small venues at local pubs (20 to 50 people). If I could get the sound out of the PA system then I'm not sure if I really need a very strong keyboard monitor (and they are very expensive!). Do I need a keyboard amp, ie, Roland KC150 65W 12" Keyboard amp? Or, would I be better off with a (cheaper) smaller powered speaker, i.e. Behringer Eurolive B110D 300W 10" Powered Speaker?
