Perform VK feedback issue update:

I'm still quite baffled that I can hook up the harmonizer to the KB aux in, and have no issues UNTIL I plug the iPad into the VK aux in. There's no logical reason that this connection should induce a feedback loop, but sometimes sonic gremlins defy logic. If I reduce the volume of the VK output, then the feedback can be controlled. Curious, and curiouser, right? This has all been preliminary testing in my studio, and not a practical hookup, which I'll try to do this week. I set it up as intended, and run a mini rehearsal to see whether its powers are for good or evil.

I did a lot of comparison research, and there is nothing in this price range that can do a better job, so if I have to make some concessions, then that's the plan. I need a light, small, quiet, all-in-one instrument for when the PA4x is a bit too much.
The Yamaha 410 was in the running, but the extra 6 inches makes it too long for all my cases. It also has wimpier speakers. This unit has to handle the kb, AND vocals without buzzing, or fuzzing.
The Yamaha 463 has no discrete audio outs without disabling the speakers. I need that monitor factor. The internal speakers will be 75-80% of the perceived sound in the room. I intend to bring an S1pro just for some added bass, and directionality.
I didn't include Casio because of SO many reasons .... mostly key flimsiness (worse than Yamaha), sounds and styles. (yup - that's everything about it)

Sooooooo, friends - my journey continues, and as I approach the destination (on stage at the winery), I feel more, and more convinced that Korg has a winner in this budget category. If the worst case scenario is that the accompaniment parts turn on each time a patter is selected, Korg has provided me with 2 handy buttons to shut off all the cheese in a split second. Not my first choice, but not a bad workaround. Sometimes, it's all about compromise.
There are a bunch of the great EPs I love in this board, and the drums sound fantastic, so add that to my vocals, and you've got a band.
(fingers crossed)
