Everyone who loves synthesizers as we do was waiting Superbooth so see new Eurorack modules and new synths.
But that was a surprise for me that most interesting and unexpected announcements came from software companies.
Spectrasonics announced Omnisphere 2.5, Propellerheads made an announcement for Reason 10.1 and a new rack extension developer that is porting their Eurorack modules to Reason rack.
Omnisphere 2.5 introduces something that was never seen in softsynths before - integration with hardware synths. And it goes far beoynd simple midi mapping of synth controls. Omnisphere recreates architecture of original hardware with specially designed presets. So you can expect your LFO and Envelopes to modulate proper parameters without even touching the software. See complete review here:
Propellehead made bunch of cool unexpected announcements:
Reason 10.1 and new player devices: Drum Sequencer by Propellerhead + 3rd party Rack Extensions (Euclidian Sequencer and others). Those players can be used with External Midi Device to send MIDI data to hardware synths/Eurorack systems
Europa Sample Loading for wavetable or spectral filter
Noise Engineering modules come to Reason rack
Behringer showed great collection of prototypes of recreations of vintage synths:
