I'll make it short : I've nothing else to add and to cut off to all the good things said about this synth by other reviewers.
Charlatan sounds pretty good, is simple, efficient with low CPU consomption. What else ?
It's my workhorse when I want to make a sound with no hassle.
This only cons is the lack of internal preset management. It uses the host one... if it has one.
Of course it's a encouragement to do sounds by ourselves and that's easy with this synth. But when I do a sound in a DAW and want to use it in a soft that doesn't offer VST presets management (like Maschine), I have to mimic the tunings by hand, like on a oldschool hardware synth with no memory. An incongruity in the digital world.
