I originally planned on getting a Roland keyboard, but I found that I'll be able to get more bang for my buck (around $500) if I go with Yamaha. The main use of the keyboard will be for arranging and to accompany my bass playing for making recordings and fill the role of several instruments, and possibly including the drum track. These are the three I've been looking at, each pretty different from each other. Yamaha DGX 300 76 keys, 32-note polyphony, good amount of sounds including a great piano sound. This is more of a piano-style keyboard, with software to teach piano (which would be helpful in that I can't really play, although the LED readout that shows the lessons may be far too small for my poor eyesight to make use of). 3 1/2 floppy and 6 track sequencer as well. Yamaha PSR 550 61 key, 32 note polyphony, tons of sounds. This is like a jacked-up version of a standard Casio-style keyboard. 16 track sequencer, 3 1/2 floppy, good overall keyboard. Yamaha S03 This is the one I'm leaning towards the most. 61 key, 64-note polyphony, tons of sounds, and has a modulation wheel. No 3 1/2 floppy drive, but it comes with recording software instead, and it seems to have better connectivity to other instruments and MIDI. All are compatible with the same DG and PSR software, and all have direct connections for a PC. Check out the links and tell me what you think would suit my needs best. Thanks in advance.
