I bought this keyboard three years ago a friend. I possdais an SL880. I t sduit the cot compact and convenient (it's a rack MODEL)
Connectivity: midi in, 2 out, jack for sustain and volume, external tranfo.
4 programmable zones, two faders for volume and programming.
2 knobs: pitch and modulation.

Solid appearance and seriousness, especially for rack MODEL: we open the lid and hop.

UTILIZATION

Touch Keyboard prcis trs heavy, it can be tiring at beginners, but you get done.
The programming is clear, fairly intuitive, especially when adj put your hands on a Fatar master keyboard. I do not have the manual.

NB: MODEL rack is more compact than the conventional MODEL.

OVERALL OPINION

I use it for 3 years. No failure or special concern.
The problem is that other keyboards do not support the comparison (that staff)
Quite far from an M-Audio keyboards or other rcents.
ON would be regretting the lack of usb, but given the age of bte ...

A single point ngatif finally the weight!
We can not have everything ....
