I had a SL MKII, and created a very good mapping for vArranger.

I did not keep this keyboard because; while the keybed was from Fatar, and has good quality, I did not like how they have implemented the velocity curve. I was not able to find a pleasant curve for me.

The pitch bend joystick was sometime not staying at the center position !

the pads had very bad touch response.

Hope this MKIII will correct all this.

I never used true anlog synth with CV inputs. It seems that today many musicians need this, because they release product to control analog synth more than VST

If thy send me one, I would create a template for vArranger
It they have a nice documentation... to take the control of the nice screens and leds... This should be very nice
