Studiologic SL88 Grand

Sadly my enjoyment of using my new SL88 Grand was shortlived! While the keys themselves are a joy to play, there are other serious issues that has to be adressed before me or any professional user can trust this product 100%.

The memory is erased every time the SL88 is powered down! I have tried over and over again to program some zones but all my efforts are wasted as they are not stored properly.
The SL Editor may look good but has some serious flaws. First of all I have to establish the USB connection everytime I launch the program. I can?t understand why these setting can?t be permanently stored.
As far as I know the patches in the project I download from the SL88 can?t be edited directly. I must first open a project file on the left hand side that matches the memory of the SL88. Then I can edit the patches. But after that I have to transfer the edited patches to the NEW project with the downloaded patches from the SL88 on the right hand side and then I must upload them to the SL88. This is very frustrating and makes the whole process a real hassle! Dragging a patch from the left side to the right will not even replace the patch I am dragging it over to. It just assign it to a new patch.
After a couple of days use the joystick/rotary knob on the front panel of the SL88 startet to get sticky in one of the directions and the whole unit feels very fragile and prone to failure.
