U-He Repro 1 - is a new history of software synthesizing. This synth is a full copy of old retro Sequential Pro 1 hardware synth but with many more possibilities. It has 5 different effects that can provide a richer sound and you can fine-tune the frequency of the sound to make it more saturated. U-He Repro 5 - the highest quality copy of Dave Smith Prophet 5 hardware synth, but also like Repro1 that has much more possibility that Prohet 5 does. Both synths are giving us a next-generation of software sounding, that already stepped over hardware and goes above!
