The Synthfest Nantes is really great to meet people and discuss with lots of passionate synth addicts and creators, technical experts and musicians.
This year there will be lots of analog modular synths and some great early digital synth demos including a Fairlight CMI II with samples provided by JM Jarre (that he sampled and used for the Zoolook album).
Here is a short demo of on of the "Axolosynth" I will show at the SynthFest Nantes:
The matrix buttons are used to set a sequence of presets that are continuously "morphed" in a sequence... it allows a lot of cool sounds.
