I am interested in obtaining a good MIDI keyboard for the purpose of composing music for my Church. I have been using a Kurzweil SP88 keyboard and Finale with some success, but this is the churches keyboard and it is pretty cumbsersome to move it back and forth Not only that but I've found some limitations. A little background- I was considering getting my own Kurzweil SP88 but the main CON is that it only supports playback on 1 midi channel. In addition to that, I've also had some strange latency problems when doing playback/recording with FINALE. I attribute that more to my setup than to the keyboard, and I do have a workaround (alternate the playback device). I have a soundblaster LIVE gamer sound card, and I purchased a Yamaha UX16 for midi in/out as well. Not sure what the problem is. Anyway, I'm looking for a good keyboard recommendation, and was hoping that I could get some advice. Price range: $600-$700 Midi: 16 channel in/out/through Polyphony: 32 or higher Feel: Velocity Keys, aftertouch, weighted or semi-weighted Pedal: Sustain, possibly one for punch in/out Sound: The least important since it will mostly be tethered to a computer, BUT if I can play it in front of people w/o it sounding like a toy, great! Keys: 76 or 88, nothing less. I really like the look/feel/sound/capability of a Roland RD-150 but the price is too high. Yamaha P60's don't seem to be bad either. Really the ideal Keyboard is the Kurzweil SP88, it just lacks the midi that I really want. I'm definitely willing to go used as well... Any suggestions / links much appreciated!
