This LFO->Filter connection will now appear in the Mod Matrix as well. Want an LFO controlling a filter cutoff? Simply drag the LFO title to the cutoff knob. The modulation system allows for drag and drop connections between mod sources and destinations. Load up Serum and we think you’ll be able to notice both what you hear (solid high frequencies, extending flat all the way up to the limits of hearing) as well as what you don’t hear (no unwanted mud or aliasing gibberish- just good, clean sound). In Serum, the native-mode (default) playback of oscillators operates with an ultra high-precision resampling, yielding an astonishingly inaudible signal-to-noise (for instance, -150 dB on a sawtooth played at 1 Khz at 44100)! This requires a lot of calculations, so Serum’s oscillator playback has been aggressively optimized using SSE2 instructions to allow for this high-quality playback without taxing your CPU any more than the typical (decent quality) soft synth already does. Many popular wavetable synthesizers are astonishingly bad at suppressing artifacts - even on a high-quality setting some create artifacts as high as -36 dB to -60 dB (level difference between fundamental on artifacts) which is well audible, and furthermore often dampening the highest wanted audible frequencies in the process, to try and suppress this unwanted sound. Artifacts mean that you are (perhaps unknowingly) crowding your mix with unwanted tones / frequencies. Without considerable care and a whole lot of number crunching, this process will create audible artifacts. Playback of wavetables requires digital resampling to play different frequencies. Processing menu options allow you to do the other tasks you would want, such as apply fades, crossfades, normalize, export, and much more. Create or process waveforms using formula functions. Generate or modify waveforms using FFT (additive). Draw directly on the waveform, with optional grid-size snapping and a variety of shape tools. Morph between various wavetables using standard linear interpolation (crossfading) or via harmonic/spectral morphing. You can import single-cycle wavetables of course, as well as many at once (with in-built sorting options, or manual re-ordering). Import audio directly from audio files - Serum has a variety of methods and options for analyzing audio for breaking it apart into individual waveforms.

Serum has a Wavetable editor built right in- you can create your own wavetables in a variety of ways. The dream synthesizer did not seem to exist: a wavetable synthesizer with a truly high-quality sound, visual and creative workflow-oriented interface to make creating and altering sounds fun instead of tedious, and the ability to “go deep” when desired - to create / import / edit / morph wavetables, and manipulate these on playback in real-time.
