These new version 3's of zynaddsubfx with ruby don't work on my new system, a recent clean stage3 installation - I don't see any instruments in the UI, so I can't do anything. The "Load Instrument" ui menu option doesn't do anything. Trying to load an individual instrument via a command line argument also doesn't do anything. However all the instruments DO show up in my ~/.zynaddsubfx-bank-cache.xml file. Oh, and the app crashes in the "Load Instrument" ruby "sub-window" when I use my scrollwheel... zyn-fusion-ui-src-3.0.6/src/mruby-widget-lib/mrblib/fcache.rb:7335:in onScroll: undefined method 'length' (NoMethodError) I haven't heard any response yet from upstream: https://github.com/zynaddsubfx/zynaddsubfx/issues/275 I tried emerge'ing with RUBY_TARGETS ruby32 and ruby33, no difference. I imagine it does work on other people's systems - what the heck is going on with mine :P. Maybe the older versions shouldn't have been removed from portage so soon? Reproducible: Always
