I’m currently rounding up the bugs, importing the old tickets from SourceForge, Twitter feed and e-mail sources, so that I can track them more efficiently, since the tracker on GitHub is really powerful and well integrated with Git.
In the next days/weeks I’ll be working on addressing most of these issues for the v4.2 release. Then v4.3 will be on its way with some changes on the settings system, which will allow for the same flexibility without the need to modify anything in the library files.
Pierre built a controller for his guitar setup, using a computer as an effect box (it also seems possible to use a Raspberry Pi). Effects are modelled with PureData, the audio is routed using Jack and the controller’s brain is an Arduino.
