Moebius Lab for iPad Released

iTunes: Moebius Lab - Amazing Noises

"Moebius Lab is a multimorphic sound processor which contains a synth, a varispeed stereo sample player, 9 time domain effects, 6 spectral effects, 7 slots for external audio application, and nearly 200 LFOs that can modulate each parameter.
You can move the effects along two chains, and get endless combinations of incredible sounds. ALL the App parameters can be modulated with dedicates LFO (one independent LFO for each parameter!).

To get you started, you have more than 200 ready-mades presets.
Each effect has an in-line help with an explanation of the parameters.

The screen is divided into 3 horizontal areas: the top one contains the sound source (Sample player/External Input/Internal Synth), the middle one contains the Time Domain Effects Chain with four slots for external apps, the bottom one contains the Spectral Effects Chain.
The two effect chains are connected in a sort of Moebius Ring: you can route the signal from the Time Domain Chain to the Spectral Chain and vice versa.
You can even add up to 7 IAA effects and/or instruments, the number of possibilities is huge!

*** LIST OF EFFECTS (NODES) ***
- EXCITER The Exciter Node distorts the signal below (Saturation) or above (Excitation) a given frequency.
- RINGER A ring modulator with distortion and feedback.
- KLAMPER Clamps the signal with some special features.
- SWARMER A “superchorus”, excellent to create super fat synth sounds (and more). It is composed by a chain of modulated delay lines.
- FILTER The Filter node has two configurations:
Dub: dual low-pass high-pass state variable filter with resonance and overlap factor.
Morph: a triple low-pass/band-pass/high-pass state variable filter with resonance and continuous morphing between the filter types.
- SPLITDEL A dual band delay with feedback.
- REDUKTOR This node can be used to decimate and do other “bad things” to your signal.
- SHIFTER A dual band frequency shifter.
- REVERSO Plays the signal in reverse at regular rate.
- BRICKWALL A spectral brickwall filter.
- GRIP This node samples and holds spectral components of the incoming signal, based on their amplitude.
- BLUR A (noisy) “spectral reverb”. The duration of the spectral components is prolonged (blurred).
- DEGRADER A spectral decimator.
- FLUTTER Flutter is a sort of animated brickwall. Two spectral sinusoidal LFOs define the frequency boundaries. The spectral components which are inside or outside (depending on the Spectral Balance) these boundaries are suppressed.
- PLATEVERB As the name suggests this is a classic Plate Reverb.
- DYNAMICS PROCESSOR You can change the output sound using a compressor and expander effect. This is used to either reduce or expand the dynamic range of an audio signal.

THE SYNTH
The internal synth contains two band limited oscillators, a complex oscillator, a ladder filter, an envelope generator and a sub-bass oscillator.

Other Features:

- Audiobus and Inter-App Audio support (sender and FX)
- Built-In​ Stereo Sampler with varispeed
- Control Manager LFO for Parameters
- Midibus, Virtual Midi and Network: 14 bit NRPN controllers

The Newest Member of the Moog Family

Spectravox, the newest member of the Moog semi-modular family, is a groundbreaking tool for sculpting sound. An analog spectral processor based around a 10-band filter bank, Spectravox creates lively drones and colorful tonal sweeps on its own and adds resonant depth and psychedelic spectral movement to any external sound. Hook up a microphone and Spectravox becomes a 10-band analog vocoder with innovative integrated modulation of all of its filters. An exploration and expansion of the topology of the vocoder and filter bank, Spectravox is a highly flexible instrument and signal processor with a comprehensive patch bay for integration into studios of all sizes.

A Groundbreaking Tool for Scultpting Sound

Synthesists have delighted in playing with the spectrum of sound since the Moog 907 Fixed Filter Bank appeared in the 1960s, creating lush vowel tones and multicolored timbral animation with hands-on level control of each frequency band of a sound. Unlike earlier fixed filter banks, however, the unique filters of Spectravox are no longer fixed in place and will jointly shift around the frequency space, allowing for the creation of otherworldly voltage-controlled spectral animation and vibrant phaser-like sweeps. With 10 filters whose variable resonance can morph from soft precision to shimmering choral effects, Spectravox reshapes the sounds you love into surprising new forms and brings a new world of sonic possibilities to your studio.

10-Band Analog Vocoder

Spectravox is a fascinating standalone sculptable synthesizer voice thanks to its built-in carrier sound source of a thick analog Moog oscillator and white noise generator. With its combo XLR/jack program input, Spectravox becomes a fully featured 10-band vocoder with a secondary filter bank for analyzing the spectral makeup of incoming sounds. In VOCODER mode its 10 analysis filters map the timbral characteristics of any external sound onto any other sound you can imagine. Shape the warm analog oscillator of Spectravox with the dynamics of your voice, or use a drum machine to animate guitar chords in a mesmerizing broadband percussive space.

Electronic Instruments for the Musician

Spectravox uses the pioneering vocoding work of Bob Moog and Wendy Carlos in the late 1960s as its inspiration—work which was based on Homer Dudley's original designs from the 1930s and which was used to prominent effect in Stanley Kubrick's 1972 film A Clockwork Orange. Innovating further from these early designs, Spectravox uses 10 state-variable filters for its filter bank, all 10 of which are capable of being shifted with its internal triangle wave LFO or external control voltage. With the ability to emphasize vowel sounds via the Hiss and Buzz functionality of the Moog 16 Channel Vocoder, Spectravox is both a major step forward for analog filter banks and a loving exploration of early music technology history.

Scramble the Frequency Spectrum

Scramble the frequency spectrum and create wonderfully unpredictable textures with patch points for each filter in the filter bank and included patch cables. Add analog warmth and subtle phasing to digital synthesizers and sound sources. Integrate Spectravox with other Moog semi-modular instruments or Eurorack modules with an extensive patch bay providing control over almost all of its parameters. Spectravox is a boundary-pushing instrument that invites you to explore creative new ways of shaping and sculpting sound.

Division 6 Filtare SEIII Eurorack Analog Modular Filter

YouTube via matrixsynth | December 27, 2010 |

It's a bit dark in here... Warning: this video is grungy, distorted and loud! Turn your speakers down and adjust up. Watch in 480p. Note it will sound better with decent headphones and/or speakers. Also the noise you hear in the beginning is the line in on the Canon T2i. It goes away the second the audio comes in. Don't be frightened. :) This is a very simple patch: 1. Audio out of a 3 OSC Moog Voyager patch with its filter wide open, no resonance and a held note into the Filtare - nothing in between and no effects. 2. Tiptop Audio Z8000 Matrix Sequencer/Programmer into 1 V/O CV in of Filtare. 3. Harvestman Zorlon Cannon 4bit out into adjustable CV in of Filtare to start, then the filter type CV in at the end. 4. Roland TR-909 for Z8000 clock and kick. What's going on: 0:00 - opening and adjusting the filter cutoff of the Filtare with no mods active and no resonance. 0:14 - adjusting resonance followed by filter 0:28 - starting sequence on Z8000 0:44 - adding Zorlon Cannon CV modulation to Filtare - note all you are hearing is the Moog running through the Filtare. No audio from the Zorlon Canon is coming through. The Zorlon is only a modulation source to the cutoff frequency of the Filtare. 1:09 - I stop the sequence and adjust the amount of modulation coming in from the Zorlon Canon so you can hear some of the spectral harmonics bleeding in and out. 1:30 - sequence kicks in again this time with the bass drum audible followed by slight adjustments. 2:26 - I get some odd rhythmic things happening with the cutoff and resonance. The 909 is still your standard 4/4 kick, so what you are hearing is the Filtare responding to the sequence. 2:44 - I increase the Zorlon Canon modulation for more grunge. 3:01 - I start to sweep the filter mode from Lowpass through Notch to Highpass. 3:12 - I bring the Zorlon Canon mod amount back down. 3:17 - I sweep back to Lowpass and add back the Zorlon making adjustments. 3:51 - I pull out the Zorlon and plug it into the CV mod for filter type. Note the Zorlon Canon 4bit out can be considered a more extreme modulation source. With something like a slower LFO or sequence, the result would of course be much smoother. This video was just a little sound exploration after first use and it did turn out very, very grungy. The Filtare is more than capable of your classic smooth filter characteristics. Check out the sound samples on to the right of the Filtare SEIII site here. Update: Timeline above updated to match YouTube. It was slightly off.

A late Christmas present arrived yesterday. The Eurorack format Filtare SEIII from Division 6.

Grungy video below...

This is a very cool filter. Some notable features include:

- Smooth adjustable transition of filter type from Lowpass through Notch to Highpass with Notch out (most filters do not allow this - see the third pic here and the video)

- CV in for filter TYPE (you can modulate the filter type!)

- Two CV ins for Filter Cutoff - one adjustable and one 1 V/O fixed

- Separate CV in for Resonance

See Division 6 for full details (also captured in this post).

"Poseidon Synth - The Ocean of Sound

For all creatures in the ocean of sound - Sonic textures from other worlds, Analog signature sounds, Cut-through-the-mix leads and silkily smooth pads: Poseidon sets a new standard for sound design and ease of use. All of this was made possible through a combination of the familiar, conceptual simplicity of the analog synthesis and our frequency domain based Spectral modelling synthesis technology.

Spectral model oscillator

Select a basic sound model from over hundred delivered with Poseidon. The basic sound model determines the sound characteristic you want to start: taking a artificial model like “Sawtooth” gives you analog style sounds. Use complex models from analyzed samples for earth shaking ambients and evolving pads.

Model parameters

High level controls allow for changing the spectral shape, the harmonicity and balances the level of residual noise and spectral amount of the oscillator model.

F-Domain Filter

The newly developed F-Domain filter allow for drastic changes in the resulting sound spectrum. Five filter types including lowpass/highpass characteristic can be used to shape the sound. They have the usual controls like cutoff but also very unusual ones like a variable slope ranging from 0 dB to 72 dB / Octave and independent controls for resonance and bandwidth! This kind of controls are only possible in the context of our F-Domain synthesis technology. This results in an extremely clear filter sound with breathtaking fast modulation possibilities.

The filter type “Inverse” interprets the sound model as a "Source" and a resonant body "Filter". The cutoff parameter shifts the filterbase - this is the equivalent to making the instrument body smaller or bigger.

Spatializer

This simple control gives your sound a distinctive moving distribution in the stereo panorama. Every atomic sound particle has it´s own path through the space !

Sound browser

The sound browser in Poseidon gives you a fast selection of sounds based on category and timbre.

Bastl Instruments Ikarie by Casper & Bastl

Playlist: Ikarie by Casper x Bastl – a uniquely sculpted, flexible stereo/dual
peak filter module Ikarie Walkthrough - Every Feature Explained Ikarie - Patch
Tips Ikarie process - designers talk - Peter Edwards and Václav Peloušek

via Bastl Instruments "Reach the peaks of alien soundscapes with your Eurorack as mission control

Bastl Instruments is very proud to announce its latest collaboration with Casperelectronics – the Eurorack stereo filter Ikarie which is robust in features yet physically compact.

Ikarie is a uniquely sculpted, flexible stereo or dual peak filter module. It can continuously transition between lowpass and highpass filtering with a single knob. It also packs in an envelope follower for the incoming audio signal, which comes in handy when you're looking to increase your sound's internal animation.

Two parallel filter cores can be modulated in sync for work in the stereo realm, set apart for unique stereo effects (with either mono or stereo signal at the base), or chained together to make a 24 dB filter.

With only the mono output of the filter used, Ikarie behaves as a dual peak filter, which evokes formant-type sounds and rich, at will piercing, throaty resonance. The Beyond output gives you the spectral difference of the two filters, effectively turning the unit into a so-called twin peak filter.

Add an internal VCA, CV control over panning and resonance, optional overdrive of the input, and you can explore a vast universe of sound design possibilities, from liquidy through pinged percussive to lush and eerie. All in a very compact form factor, with tons of space for precision and creativity.

This module results from a collaboration between Václav Peloušek of Bastl Instruments and Peter Edwards of Casperelectronics. While Edwards' obsessive attention to detail gave this filter a uniquely balanced resonance and envelope response, the expertise of Peloušek delivered a one-hand user experience filter with a distinctive control scheme at a minimal footprint.

The module's name alludes to the 1963 Czech sci-fi movie Ikarie XB-1 (released as Voyage to the End of the Universe in the US), and the film served as the module's inspiration in many aspects. Long before Solaris, Space Odyssey 2001, or Star Wars, Ikarie focused on the subject of space exploration, and it paved the way for many to come. With its early electronic sound design and musical experimentation under the lead of Zdeněk Liška, immersive cinematography, and impressive production level, it remains one of the most original and exciting film titles in the science fiction genre. Bastl & Casper's Ikarie proudly carries the flag of this cinematic world.

Ikarie will be available on November 12th, through noise.kitchen and synth stores worldwide for MSRP 240 EUR without VAT.

two parallel filter cores (left and right)
based on 12dB/oct state variable filter topology

Future Sound Systems FIL2 Spectral Devastator Dual VCF

Note: links to listings are affiliate links for which the site may be compensated.

via this auction

"A unique and versatile pair of filters that compliment each other quite well!

The Spectral Devastator features a brand new filter core, designed by FSS through finding ways to implement voltage control for a resonant active filter. The method of CV involves passing the audio input through the CV stage, but whilst the CV implementation is non-linear, distortion and waveshaping of the audio occurs, particularly with high resonance. This circuitry also results in a filter that self oscillates not sinusoidally, but with a sawtooth-like waveform.

Two filter sections (highpass and lowpass) can be normalled together to create serial or parallel processing of the same input, whilst the highpass' cut-off control is normalled to the secondary CV input of the lowpass filter via a variable attenuator.

At low resonances, the filter gently rolls off frequencies above the cut-off point. Tweak the resonance past 12 o'clock and the filter begins to growl. Crank it up to 10 and you've got a filter that adds harmonics to your original input, based upon that input's harmonic content. Unplug the input and use the two filter sections as VCOs. Plug audio into the CV inputs and create swarms of noise. Use the highpass section as a VCO and the lowpass section to filter its output, giving you the core of any acid bassline you could ever want.

Highpass and Lowpass filter sections
Cutoff knob per filter
Resonance knob per filter
CV2 Depth knob per filter

"This auction is for an exceptionally rare Syntrack analogue synth module, made by the swiss company Spectral Audio. As far as i'm aware only 200 of these were initially made around 1998, and then they were available for a short while as custom built units to order, but there can't be that many in the world.

The Syntrack is a rackmounted analogue synth module with full midi control over the knobs and parameters. All the knobs respond to, and transmit midi data, so any knob movements can be recorded and automated on playback. It has a single wavetable DCO with a 100% analogue filter and VCA. Theres also an external audio input round the back so you can send any signal through the filter and savage VCA distortion.

This unit sounds like nothing else you've heard. Not only is it home to some massive dirty analogue bass sounds and leads, but it also does an excellent line in digital chiptune style sounds. Imagine an 8 bit computer or gameboy running through a meaty analogue filter and distortion. To quote sound on sound magazine: 'The Syntrack's upper register exalts in its cheesy, '60s, battery-powered organ sounds, and for me this is nothing to be ashamed of.'

According to the spectral audio website HERE, the synth features:

99 Programs (1 .. 29 = Presets, 30 .. 99 = free definable Programs)
Wavetable Oscillator with 100 Waves (expandable to 200)
Analogue 24 dB Cascade Filter with Resonance and Self oscillation
2 Envelopes
LFO
Full MIDI Control
Velocity and After touch sensitivity
Key follow
Retrigger Function
MIDI In / Out / Thru
Audio Filter Input
19" / 1 Rack Spaces
Light Blue coloured Front Panel (if you want to call that random collection of fonts and styling a feature!)"

Zlob Introduces the VC F3DB Fixed Filter Bank Eurorack Module

What is a Fixed Filter Bank? | Chaos + Control with Zlob VC F3DBvideo upload by Sarah Belle Reid

"In this video, we explore the history of fixed filter banks in synthesizers (what they are, how they work), demonstrate some classic fixed filter bank concepts, and then dive into a series of patch examples exploring the Zlob Modular VC F3DB.

Zlob Modular's VC F3DB is a filter bank for Eurorack modular synthesizers. But it's much more than just that as well; while it can produce the clean, dry, nasal tones you might expect from a classic Moog or Buchla filter bank, it is designed to leverage feedback, clipping, and per-band envelope followers, allowing it to act as a chaotic sound source, spectral decoder, and intense distortion.

Zlob VC F3DB First Look video upload by Brett Naucke

"A first look at this fantastic new 6-Band Voltage Controlled Filterbank by Zlob Modular. Patch examples including manual filtering, drum processing, voltage controlled filter animation, 'vocoding' and some exploitations using the filterbank as a chaotic audio source. This is a GREAT filterbank capable of some very unique overdrive and distortion functions that set it apart from all other filterbanks in eurorack modular."

"VC F3DB stands for Voltage Controlled Fixed Filter Feedback Distortion Bank. The simplest description is it’s a 16hp six band voltage controlled fixed filter bank. But with the additions of so much gain, clipping, feedback, and self-oscillation it becomes a very flexible and unique gestural sound sculpting tool capable of; graphic equalization over 6 octaves, multi-band distortion, spectral processing, crude vocoding, multi-frequency envelope following, self-modulation, and even as an instrument on its own. With no input it can be used as a pseudo chaotic “harmonic” feedback oscillator.

The filter frequencies were specifically chosen to emphasize more ambiguous and dissonant intervals. Although the frequency bands are spread out over many octaves I purposely tried to leave out “3rds” besides a major 10th at the top frequencies to even out all the dissonance below. But the frequencies aren’t exactly equal tempered, so it’s relative. The bands roughly equate to F2, B3, F#5, C6, F7, A8.

The design is based on the Moog 914 filterbank, which it borrows the frequency bands from. But this circuit uses active filters with opamps inspired by YU Synth opposed to passive cells using inductors on the original. The 88hz is a low pass -24db/oct and 7k is a high pass -24db/oct, the rest are -12db/oct band pass filters all with a Q around 4.

The hard and soft clipping circuit on the input is fairly standard which appears in many different iterations of classic guitar pedals. But it has a lot of gain and can even boost line level signals. What makes it a bit unique is the feedback on the clipping circuit which needs to be turned on by the GFB(gain feedback) switch and the amount can be controlled by the Gain FB pot which can add some fuzz/bite to the signal depending on which clipping switch is engaged or at the extremes it will self oscillate from audio rate to LFO sort of clicking range. All the clipping stages in the module are using silicon diodes.

Consult the Signal Flow Chart to the left for a rough visual breakdown of the controls,in/outs,normalizations, and optional settings for the module.

Each band can also be muted by the top toggle switches or clipped(at the VCA) by the top slide switch which makes this design a bit different than other filter banks. As well as the overall feedback section(bottom middle) takes the sum/all bands out through a VCA(controlled by the feedback pot and FB CV) back to the input gain/clip circuit. and you can also tap into this using different sends/bands to the FB In jack to break the normalization. With this extra feedback “resonance” you can get more whistley and howly filter sounds kinda like the Serge res eq, which can also go into self oscillation.

All cv ins are expecting +5v to open the VCAs(they wont respond to negative voltage), once you get closer to +8v or so it can clip the vca regardless of the gain settings or clip switches. Output amplitude in high gain settings will exceed 10vpp and can get up to 20vpp. The envelope followers tend to stay around 0-5v out, but with clip switch active they can go up to 10v.

Since this is a high gain module there can be bleed between the bands in certain configurations and situations. Also in high gain modes with higher frequencies the 2.8k and 7k bands can bleed a little with the VCAs closed.

This is a highly involved DIY all through hole project. It is a long build with 5 different pcbs to solder and assemble.

THIS IS NOT A BEGINNER OR INTERMEDIATE PROJECT."

Electro-Harmonix HOG Octave Generator Synthesizer Guitar Effect

Note: links to listings are affiliate links for which the site may be compensated. via this auction
I was going to pop this one up on MATRIXSYNTH-BB, but figured it was an interesting reminder of what else is out there in the synth world. Electro Harmonix pedals tend to cross over to the synth realm not only with their dedicated synth pedals like the HOG, but others as well. See the EHX label at the bottom of this post and scroll through posts for more.

"Generate everything from extreme sub bass to powerful multi-octave chords with this harmonic octave generator!

Blast off to a whole new universe of sounds with the Electro-Harmonix HOG, a polyphonic guitar synthesizer with NO special pickup required. It gives you complete control of up to 10 interval pitches including fifth and third intervals, glistening filter sweeps, and insane pitch bends. Dedicated filtering and envelope control, with numerous setup options, make the HOG a must-have performance instrument.

The HOG can simultaneously generate multiple octaves and harmonics from your input signal. Whether you play single notes, arpeggios or full chords, the HOG will track every note you play. In addition, the HOG has seven expression modes that enable you to modify your sounds using the included expression pedal, a MIDI controller, or the expression button on the HOG itself. There is also an amplitude envelope and a 2nd order low-pass filter with resonance. The optional EH Foot Controller (I am listing separately) allows you to store and load six presets.

You have control over the HOG's basic audio circuitry with an input gain slider (with clip LED), a dry output slider, and a bypass switch. Audio I/O includes 1/4" Hi-Z input, 1/4" output, and a buffered direct output jack. The voice controls let you access the polyphonic synthesizer section. There are 10 voice sliders on the HOG, each with a white cap with a black line that controls the output volume for its voice. The ten sliders let you generate notes two octaves down, one octave down, the incoming signal, a fifth up, one octave up, an octave up plus a fifth, two octaves up, two octaves up plus a third, three octaves up, and four octaves up. The selectable envelope section controls the amplitude attack or decay of the voices, with separate sliders for the lower five voices and upper five voices.

The Spectral Gate button activates circuitry that emphasizes the loudest frequency or harmonic and reduces the volumes of all other present frequencies and harmonics. The filter frequency slider controls the cutoff or peak frequency of the low pass filter, while the filter resonance slider controls the Q or peak of the filter.

The HOG's seven different expression modes are selected consecutively by the expression mode switch: bend one octave, bend one step, volume, freeze plus gliss, freeze plus volume, wah-wah, and a filter. There is also an expression reverse mode and you can control the expression modes externally with an expression pedal or modulate any of the expression modes using MIDI pitch bend.
