After updating to version 1.5 or 1.6 (in either OS9 or OSX, standalone or VST), the modulation controller has unexpected results. LFO is applied, but the basic pitch of the note changes. For example, a middle C will have vibrato, but it will lose its reference to middle C, going sharp or flat unpredictably.
This is replicable on each of my Macs. The bug is absent in earlier versions of MiniMg V.
