Just updated Analog Lab to 1.2.2.47. Multis still work fine, but no single sound patches are producing notes from C3 to C1. Anyone else having this problem?
EDIT: Problem is with the standalone version only; AU plugin works fine. Mac OS 10.9.5.
EDIT 2: I deleted all traces of Analog Lab and reinstalled: everything now seems fine. The full range of keys are now playable, and overall stability is improved.
