couple of weird bugs in the latest version on a Mac (yosemite 10.10.5). in no particular order:
text source editor doesn’t update line numbers (tested in Studio and in Cabbage as well). you can scroll though text but line number will not update until you click on the window and resize.
in Cabbage Studio:
the X/Y pad on various synths is broken but the X and Y sliders can be manipulated in the sidebar at the top left.
on synths with presets, display of the selected preset gets immediately blanked out when selected. i seem to remember the earlier version of Cabbage Studio had this issue as well.
the hsboscil synth Mod.Shape menu does not appear to change waveform from the dropdown list. the controls in the upper left sidebar do change though.
in the ePad synth, all controls in the upper left corner do not work, but again they can be adjusted in the sidebar slider area.
hope this helps a bit,
scott
