I did a preorder, and Thomann sent it the same day as they got it in.
I use this in my studio for piano, strings and synth. I'm a heavy Kontakt user, but do not like the Komplete Kontrol software (nice for browsing, but not for my use). I like the features of the SL88 better than the NI S88, and it's quite cheaper too. I use an Akai mpd226 to control my daw and pads.
Four zones on different midi channels - great for splits, 3 sticks, onboard editing possibilities and software (on the second midi input so you can use it at the same time as your DAW), aftertouch, USB-buspowered (you do not need to use the powersupply), true halfpedaling (with the slp3).
Keybed: tp100lr - same as in NI S88(a version of it), Arturia Keylab88, several Kurzweil, several Nord and more..
The keybed feels great, but A0 got some low rattling noise when struck hard - maybe the hammer is loose or something. Keybednoise is slightly different from middle c and up (a sharper noise) then below. Still the keybed is fairly quiet (I did expect more noise after seeing the Arturia Keylab88 video. Triple sensors works great, I can retrigger without the keys go all the way back up. Aftertouch is heavy and need some force.
Pros:
The price
Weight
Great keybed
USB-powered
Aftertouch
Editor
3 XY sticks
Cons:
Some keybed noise
Keys could be faster (triple sensor counter this)
Can't be beaten at this price point. Recommended!
