This free Reason ReFill mimics the "time correct" function invented by Roger Linn. He included it in the first Linn drums and, carried this feature with him to the Akai MPC and even today, on to the Tempest.
Here is a FREE synth ReFill I made from my Korg Monotron. There are combinators made entirely from waveforms, from Thor only, and others combining methods. I played the synth live to make the 32 Rex loops. There are also 2 synth "emulations", skins and an insert effect.
