I was not looking for this bug, but wanted to render how small plugin can change chip sound and how to create some nice bass.
So inside ZIP you can find 2 files - xrns (of course) and “3rd bass” VST (if you don’t trust me as source - here is original source - link). First pattern is just chip sound without VST effect, second is with effect enabled.
And now - Renoise plays it proper. Then when you render in realtime - everything works. When you render in offline mode - Renosie hangs (when auto-suspend is enabled in plugin options) or generates silence when plugin is triggered to start (second pattern).
What is not typical in this example - I must change value of effect using envelope, because commands are limited and cannot be used for it.
I really want new Renoise version with better, fixed render.
