Description: Initially, when creating Serum, we aimed to have a dream synthesizer that did not exist: a wave synthesizer with truly high-quality sound, a visual and creative interface focused on the workflow, so that creating and changing sounds is fun and not tedious, and with the ability to «deepen» into the process if desired — create, import, edit and transform wave tables, and also manipulate them when playing in real time.
Serum version 2 opens up wide possibilities for working with sound, offering the user incredible power, control and expressiveness — many types of oscillators, flexible routing of effects, arpeggiator and sequencer for clips. The goal of Serum 2 — is to give Serum users the opportunity to fully realize their sound and musical ideas. Have we already mentioned that Serum 2 — is a free update for Serum 1 owners? Lifetime Free Updates — These are truly lifetime free updates.
