We say :

Roland's SH-01A is another excellent synthesizer from their Boutique range. This is a reproduction of their legendary SH-101 analogue synth and offers users access to a recreation of the original analgue circuits through Roland's ACB technology. Don't forget to buy a K25M to go with your SH-01A if you don't happen to have a MIDI keyboard laying around. 

Roland say : 

The SH-01A is a meticulous reproduction of the iconic Roland SH-101, one of the most popular classic synthesizers of all time. Our Analog Circuit Behavior (ACB) technology reproduces the SH-101’s legendary sounds by faithfully recreating the actual behavior of the original analog circuits, right down to the fine details and odd quirks that have endeared the synth to musicians and producers for decades. The SH-01A builds on the great sounds and creative immediacy of the original, now in the popular Roland Boutique format—offering exciting new polyphonic capabilities, inspiring new performance features, and a level of authenticity that could only come from Roland.
