  1. The demos sound really cool. It’s a really nice first impression. There’s the grit of the 8 bit in the oscillators, the filters sound really good to me! Having LFOs and independent envelopes for amp & cutoff is cool.

    I took a quick visit to the website and read a little. Sounds like a great developer who’s doing it for all the right reasons! I suspect this little synth will be flying off the shelves.

    I couldn’t tell from what I read whether any parameters can be controlled externally via midi.

  2. I was one of the first people to finish their Rockits from the kickstarter and lemme just say, its a great little synth. It has lots of awesome little features, and has lots of nice things coming in new software versions for it. I really dig the filter on this thing. It is one of the better DIY filters out there. It has 3 modes, HP, BP, LP and can sound really aggressive and squelchy or smooth and mellow. It is definitely a synthesizer with personality and sounds a bit better (to me) than the shruthi 1 does with the standard SMR-4 filter.

    All the parameters can be controlled via midi, and it also makes for a nice midi control surface.

    It’s a great synth with a hopeful future!
