Yeah we waited in line for maybe 40 mins at around 3:30… it was pretty packed inside (we went to the synth bit) but with some persistence you could get to play with stuff and it quietened down towards the end.
Would have been better to let fewer people in but enjoyed it anyway, was fun to get to play with some stuff I never thought I would (OBX8, Prophet etc.). I suspect it was just more popular than they expected, hopefully they can do it again in a larger venue
