Hey, I'm involved in Praise and Worship music a lot, and would like to ask if anyone else in this field has made a choice btwn purchasing the Yamah9000pro or Solton SD-1, and what their criteria and observations were? I just bought an SD1 today, and used to use a Roland E-86. One feature I really need is the ability to create a spontaneous chord progression during worship, then loop it, and add various instruments live to build the impact and effect. Now with the vocalization technology I can just imagine the power to touch people's emotions in a live worship setting. Anybody out there have some comments about any of this? ~Steve K
