I owned a DX7 II keyboard many years ago and enjoyed it quite a bit. Then I went into the Yamaha SY series. I still have a SY99 keyboard but the keys themselves have lost their lively-ness to them. Especially the middle keys most played. Just sitting around collecting dust now. Would cost to much too repair and FM sounds are not worth it anymore with all the great sampled keyboards. Thanks for the video of the past keyboard.
