--- Comment #3 from Tres Finocchiaro tres.finocchiaro@gmail.com --- Steps to reproduce:
* Download LMMS x86_64 nightly version (this link will eventually expire, any "nightly appimage from our downloads page will do until the patch is merged) https://lmms.io/download/artifact/3481767587
* Download and extract Synth1 VST Plugin here (extract to Downloads folder): https://daichilab.sakura.ne.jp/softsynth/Synth1V113beta3.zip
* Start LMMS by double-clicking on the .AppImage file
* On the left-hand side browse to "My Home", "Downloads", "Synth1"
* Drag "Synth1 VST64.dll" into an empty area of the Song-Editor
* Wait for the synth to load
* Once loaded, click the track label in the Song-Editor for Synth1 to open the Instrument window.
* Play a note through Synth1 by clicking a note on the piano at the bottom of the Instrument window.
* Play a second note, Synth1 will crash.
NOTE: Baseline testing a "good" result is a bit harder due to unrelated dependency changes in wine over the years, however we can provide a "working build" from older wineg++ versions by temporarily switching our CI to before the offending patch.
