Hi Karl-Max. Thanks for (trying to) try Piper ;-) Karl-Max Wagner wrote: > > Toolbox load error: /usr/local/lib/audio_blocks.tlb: undefined symbol: connectToNode__4NodeUiP4NodeUi The audio_blocks library does belong to Overflow/Piper (the PL), and it is pretty obvious that there is a dependency problem (perhaps a needed library). I can't be of much more help than that, unfortunately, since that is Jean-Marc's domain, but I wanted to be sure that someone got back to you right away. We'll wait patiently for Jean-Marc's reply.
