Curious about the Spectralis 2?

Surely this means you’d like to know what it sounds like!

Beside some state of the art demo-songs, we also demonstrate the individual sections by themselves. This will allow you a much better evaluation how good the quality of the sound-engine really is.

State of the art demo songs

Sit back and enjoy some demo songs of the Spectralis 2 hybrid synthesizer which is not only suitable for all electronic music genres.



  • ChillnSpeck (Track 1)

    Some dreamy ambient, one of the new Spectralis 2 factory songs.

  • Radikal Funky (Track 2)

    The 80´s. Nothing more to say ; )

  • Groove Test (Track 3)

    A song recorded with the brand new shuffle options.

  • LFO-ONE Spacemelodie (Track 4)

    Just one early space track from the neverending output of lfo-one, visit him @ www.myspace.com/speckiman

Analog Filters

Explore the full sound potential of the spectralis analog filter section. The 24dB Lowpass-Filter and the 12 dB Multimode filter both are self resonating filters and the exact tracking allows to use the filters as additional sound-sources as well. Listen to what we expect a modern Synthesizer should sound!



  • Sequence1 (Track 1)

    The first sound demo shows the warm analogue sound of the spectralis filter-section. The deep bass sound in the background will breeze some warm air into your room...

  • Sequence2 (Track 2)

    Here you can explore the opportunity of the spectralis step-sequencer, to create parameter modulation sequencer lines with different lengths on selected parameters. Here the cutoff frequencies of both filters were modulated.

  • Sequence3 (Track 3)

    Thinking the spectralis always produce warm and fat sounds? Listen to this and experience something completly different.

  • Soft (Track 4)

    Warm Softbrass-Solosound.

  • Rock (Track 5)

    Synth-Lead Sound.

  • Lucky (Track 6)

    One of the best known vintage Synthesizer sounds so far

  • Funky (Track 7)

    Funky Synth Lead sound with the typical medium speed vibrato

  • Hook (Track 8)

    A typical techno Hookline Synth sound. We added a bass sound and some 909 samples with the DSP sound engine. For this demo we used the individual outputs of the spectralis. The synth sound was processed with an external reverbration processor.

  • Shit (Track 9)

    Pushing some air aroundis fun too, sometimes

  • Multi (Track 10)

    This arrangement contains 4 different tracks, the basic background sequence created with the step-sequencer, 2 different solo-synthesizer sounds and one Filter FM sound effect, which were recorded and mixed using a harddisk-recording-system.

  • Force (Track 11)

    This Live-Session was done only with one drum-pattern and one Stepsequencer-Track. You will hear realtime sound changes and pattern manipulations.

  • Reso (Track 12)

    Are you curious, if our Filters could self-resonate? You will find the answer in this lowpass-filter solo. Remember: It’s only the filter, not a single oscillator is used in this demo.

Fixed Filterbank

The FIXED FILTERBANK was the core idea behind the whole Spectralis/Spectron concept. After designing and testing a multitude of various analog versions of the idea, we decided in the end that a digital implementation provided considerably better results. According to our motto – if it can be improved, let’s improve it – you can now benefit from the most powerful filterbank available today – at least in our humble opinion. The range of the bands now goes up to 40dB, the quality, the spreading of the cascaded band-passes and the frequencies of the individual bands can all be edited. You can experience the end-result of all this – soundwise – by clicking on the Filterbank-Demo buttons to the left.



  • Noise I (Track 1)

    We are presenting this audio sample as a filterbank appetizer, it demonstrates what can be generated using a simple pink-noise source. The levels of the individual Filterbands are controlled dynamically with the help of the envelope-curves of the step sequencer. You will hear us making realtime changes to the parameters Resonance Q and the spreading of the cascaded bandpass filters. CAUTION! – the demo generates considerable oomph (boost) via the lowpass-filter. We cannot guarantee the survival of inferior speakersystems. Please keep one hand on the volume control as a safeguard;-)

  • Noise II (Track 2)

    Simple Noise again. All what you hear is noise, the filterbank, the analog filters and of course the step sequencer engine.The percussion effects you may recognize are simple enveloped volume controls for different Filterbank bands

  • Krzt (Track 3)

    This sample shows, how the filterbank can improve the authenticity of machine noises. A wild mix of bitrate-reduced oscillators modulating each other is processed thru a fixed setting of the filterbank. Especially towards the end of the sample you will hear a remarkable resemblance to a vehicle commonly used on farms. Of course we didn’t use any samples to create this sound. What you’re hearing is simply the result of a totally nutty setting of the Spectralis’ powerful Sound-Engine.

DSP-Engine

The Hybrid synth engine together with the sample based engine combined with the advanced sequencer functiontionality is the perfect instrument for your studio and live work. All what you listen to is just the spectralis recorded via the two Main-Outputs of the spectralis.



  • DirtyGroove (Track 1)

    Heavy filtered drum-instruments and 192th note triggers, which turn a simple fingersnap sample into an oscillator-signal. (based on factory patterns of song 13)

  • Guitar (Track 2)

    The hybrid synth sound sometimes reminds a little bit of a jazz- or acoustic guitar. This sound uses only one oscillator with LFO modulation on time liniearity and waveform selection. (based on factory patterns of song 14)

  • Freerunning Tribute (Track 3)

    The DSP synth is now capable of Sample Start Point Modulation and offers Unisono Modes with adjustable Detune. (based on factory patterns of song 14)

  • Soft Embient (Track 4)

    Synth Pads from the DSP Engine are getting modulated by the Fixed Filterbank. You also will hear some very moogish sounds. (based on factory patterns of song 12)

  • Drum and Bass (Track 5)

    Starting with some strange electro beats, this demo ends with some Drums and Bass stuff. (based on factory patterns of song 9)

  • Powerhouse (Track 6)

    Some electro beats and heavy Filterbank Modulations are resulting in a fascinating groovy session. (based on factory patterns of song 8)

  • Shine On (Track 7)

    Some of the most popular synth sounds ever - recreated with just one spectralis. The Special FX sounds at the beginning were created with the hybrid synth and have been sampled and imported into the DSP engine afterwards to keep the hybrid engine free for playing the synth melody instead of the FX’s.

  • Electro (Track 8)

    A little more dirty characthas been programmed for these electro beats. (based on factory patterns of song 1)

  • Filterbankgroove with Pad (Track 9)

    A groove, created with the step sequencer and the hybrid synth together wih some nice sounding chords. (based on factory patterns of song 2)

  • Triolen (Track 10)

    String-Ensemble samples are the doing a good job if one need a good carrier signal for the Fixed Filterbank Modulations.(based on factory patterns of song 8)

Oscillators

The Oscillators are the heart of any sound-creation. The Spectralis Oscillator Section provides 4 digital oscillators with continous wave selection, Oscillator-Sync, Ring-Modulation, Frequency-Modulation, Phase-Modulation, Bit-Reduction per Oscillator, Tune-Scaling, independent Glide for each Oscillator, Pulsewidth-Modulation, linear detune, 2 independent envelope-curves for each Oscillator for volume adjustment and pitchcontrol-effects.



  • Mix (Track 1)

    1.) FM, PM and Pitch-Envelopes are used for a this strange sound
    2.) Vocal-Character Filterbank example
    3.) Deep pitch Bend Action
    4.) Hard-Sync
    5.) Phatt, warm Synthie Soud
    6.) Kling, Klang, Klong...
    7.) Ringmodulation + Glide Pattern
    8.) Pitch Down - no comment
    9.) Time Linearity Modulation gives this one oscillator example this phatt character
    10.) Techno-Hookline - also with only one oszillator!
    11.) Digital Vintage by adding some Bit-Reduction.
    12.) something very different (FM, PM, Pitch Envelopes and Ringmodulator)

  • FM (Track 2)

    Two of the four oscillators can be used as phase-modulators for the other two oscillators. This kind of modulation is generally referred to as FM (Frequency-Modulation). In our sample only one Phase-Modulator is being used. As the sample progresses, you will first hear the effect of the changes in the Modulator waveform on the overall sound-experience. Directly thereafter we changed the pitch of the Modulator in halftone steps….

  • Sync (Track 3)

    In this audio sample you can check out the Oscillator-Synchronisation of the Spectralis. This Sequence showcases two sound progressions, which are played successively. At first you will hear the synchronised Oscillators being tuned – then we are adding some frequency modulation for good measure. Don’t be surprised if the end-result is a little on the “mean” side.

  • Additive (Track 4)

    When designing the Oscillators we particularly emphasized the need to avoid generating any kind of Aliasing , even in the higher ranges. This now enables you to stack additive overtones to create new sound colors. In the somewhat pretty Sequence presented here the overall sound is being further improved with a little Glide in one of the higher pitched Oscillators.

  • Saw (Track 5)

    This Audio sample features a typical Lead-Synth Sound, a sound very popular in the 70’s. The spotty timing of the playing requires some getting used to, it is the result of the programmer working without the benefit of quantising (something that would have been quite helpful given the programmers lack of practice time in recent months;-)). You can hear two oscillators with selected sawtooth waveform and a slight detune.

  • Karlheinz (Track 6)

    In closing the following is a not so serious contribution for Karlheinz, who was anxious to find out if the Spectralis can generate typical brass sounds also. As the filters in this section are not ready to be demonstrated yet, we’ll resort to the basic oscillator setting necessary for this task, which requires independent pitchcontrol-envelope curves for the Oscillators. Only two of the four Oscillators are being used in this audio sample.

All Demos were recorded without the use of compressors or EQ’s to affect the sounds. What you hear is pure Spectralis sound. We did take the liberty though to add a little bit of Delay.
