Primer

great tool to go along with Syntorial.

well organized tutorials and on-your-own patches.

For a Free Synth that INCLUDES fantastic and fast YouTube tutorials that EXPLAIN the WHY in the sound design, it gets all the stars from me.

Primer in its current form is quite a surprisingly nice little synth. It surely wasn't meant to compete among synths, considering the strongly limited modulation options, but with a little loving care and the right motivation it can deliver unexpected sound gems.

Indeed it makes a decent "first synth" for beginners. It introduces a variety of subtractive synthesis features in a sort of rudimentary form. At the same time this could be a little misleading or confusing more than it should. But it's that exact weirdness that adds a unique charm to it, too.

I confidently recommend to play with it a bit more, because of the unique charm you may encounter and wouldn't want to miss. Who ever would combine sync, ring and FM?

Beside its wildness, it can serve up some clean and full sounding bread'n'butter synth sounds, too.
