Brainstormer

Roazhon DSP has released BrainStormer, a freeware virtual analogue synthesizer (with FM and ring modulation capabilities). 
The sound of BrainStormer reminds me of the legendary Synth1 in the sense that it doesn’t try to sound too analogue or vintage. It is simply a decent sounding VA synthesizer with a good set of filters and standard oscillators, paired up with x2 oversampling to enhance the sound. No more, no less. What I loved about this synthesizer, though, was the easy workflow and the look and feel of a solid and well thought-out software instrument.
