I went to the last one. The vibe was strange - parts of it made me feel quite disgusted by the whole modular synth scene. It was very apparent that the industry is sustained by people who enjoy buying expensive things. The experience made me question my own interests in music tech.
On the other hand there were some really fascinating talks, one about the shared history of synthesisers and military technology was especially good - and it was nice to see so many people with a shared love of making weird noises.
