Repro-1 serves up plentiful modulation options, with a saw/triangle/pulse LFO, plus a separate Mod section with Mod Filter envelope, Mod Oscillator B, And Mod LFO. There’s an advanced arpeggiator and step sequencer that sync to clock or the main LFO. A very complete Glide section and Amp Envelope with curve trim complete the top panel proper.

Talk about value — this thing comes loaded! If virtual analog synthesis plays a part in your music, you owe it to yourself to check out the u-he Repro-1.
