"The Bass and Lead need some work but everything else is perfect! One of the best cosmetically that I have seen, bright and vibrant, touch sense works perfectly, all lights work etc, sounds wonderful. Please see the pictures and the video.

The oscillators don't fire from the lead or bass section. The filters make noise but not the oscillators.
The arpeggiator is not making sound.
Everything else works fine (strings, polysense, noise on all keys)
There are a few tips missing/broken on the sliders but you can get those replacements online and there aren't many missing."
