Largo is the first pure software synthesizer with Waldorf DNA. Largo mirrors the technology used in Blofeld and Q hardware synthesizers. As with every Waldorf instrument, ergonomics are a core feature on screen as well. Your eyes will be pleased with a clearly structured, graphical user interface that supports your workflow intuitively.

Largo offers three fat oscillators, two of them with sub oscillators. These oscillators include models of classic analog waveforms as well as a selection of waves from the PPG and Waldorf Wave stored in two Wavetables. All these run through two Waldorf multi-mode filters with steep cut-off, resonance up to self-oscillation and a drive stage to add even more punch and graininess to the sound. Ultra-fast envelope generators and flexible LFOs as well as an easy to understand, yet extremely versatile modulation matrix make for a sound designer's dream.

The filters have always been a core part of any Waldorf instrument. With outstanding expertise in both analog and digital synthesis, the developers took utmost care in developing the filters. Use the comb filters for plucked, stringed or blown sounds. Band pass, high pass, low pass and notch filters are all available with 12 dB and 24 dB slope. All of them sound extremely accurate and add pure sonic quality to the sound of your music.

Largo contains a flexible arpeggiator with 16 freely programmable steps as known from the exclusive Q synthesizer line plus an array of high quality effects such as Chorus, Flanger, Phaser, Overdrive, Delay and Reverb.

The clearly arranged user interface helps you to create your own powerful synthesizer sounds in a breeze. Oscillators and filters are always in direct access while the sub-modules are only a mouse click away. It has the same exclusive voice architecture as the Q and Blofeld synthesizer line, fully integrated into the total recall system of your Digital Audio Workstation.

That's the case with any Steinberg eLicenser software. Most developers won't even give you a replacement. The hard disk licenser is primarily for demoing so you don't have to buy a $25 USB eLicenser just to demo the software (like you do with iLok, unless that's changed). The USB licenser is dirt cheap and eliminates all of this trouble. It's not exclusive to Waldorf.
