Before making purchase please consider following points :1. Sample Audio Pads doesn't Auto Off :----------------------------------------------------While switching to the next Audio Pad, previous Audio Pad playing the sample loop doesn't automatically Stop i.e. previously pressed / active Pad playing the sample loop continue playing along with the next Pad and you have to press the previous Pad again manually to stop playing.2. Favorite Tone & Sample Loop can not be changed simultaneously :-------------------------------------------------------------------------------------------While playing a song / performance, it is not possible to change both Favorite Tones as well as Audio Sample Loops simultaneously as both belongs to different Modes ( Favorites & Sampler modes ) sharing / covering the same 16 Pads. This is not in case of Roland XPS Keyboard where there are separate buttons / pads to change Favorite Tones and Samples Loops simultaneously.3. Tone Cut issue :-----------------------While switching from one Tone to another Tone ( in any of the mode viz. COMBI / PROG / Favorite etc.) already / currently playing Tone stops immediately despite holding the key or using sustain pedal, which leads to sudden cut in performance / sound.4. Few items under Global Settings don't Save permanently :-------------------------------------------------------------------------------Few items under "Global Settings" do not save permanently ( i.e. after switch Off and On the Keyboard) even after performing "Write Global Setting" option (available under Function Menu) in order to make the changes permanent. For example, Changing Audio Pad volume using the option "Audio Play Level" available under "PREF 2" menu ofGlobal Settings.Keeping in view of the above issues, I personally believe that Roland XPS 30 is better.
