There is also a demo available, but use time is limited to 15 minutes, so that’ll quickly get frustrating after using it for a bit. The full-featured version of Serum is available on the Xfer Records website for $189 USD. The first way is to get either the paid or demo version direct from Xfer themselves.
However, if you’re yet to download Serum, you can get through two main avenues. 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).Before we get into the tutorial, if you’ve already bought or got a trial of Serum you can skip this section. 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.
