Expert Sleepers has updated its Silent Way ES-4 Controller software to version 1.6.12.
In this version DINsync and MIDI clock generation has been largely rewritten, offering much improved behaviour.
Also, an offset control has been added to each, to allow the timing to be brought forward or pushed back by a small amount, to compensate for any timing delays in the hardware being synced.
