HI Zuki,
I use an first generation Ipad and the stand is a Hercules. I also had a GigEasy stand but I like the Hercules better. Over the years I have collected virtually thousands of PDF leadsheets for it. Yes, I have been putting in 8-9 hours every day for the last week on learning how to do things and today ventured into adjusting various track settings within the styles. You can do a lot with this keyboard if you have the time and are willing to do the work. Hopefully by next week I will have gotten to the various sound tweaking features. I am enjoying all the "messing around" with things. It sure is different from the Yamaha keyboards I have owned.
