Read full description

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 - File Manager, sharing common audio files via iTunes, Dropbox and AudioCopy - Snapshots Presets Morphing Pad

VAPoly is a virtual analog 8 voice polyphonic synthesizer for iPhone, iPad and Mac. VAPoly features built-in effects, built-in sequencer, parameter automation, oscilloscopes and spectrum analyzer. VAPoly works as a stand alone or as an Audio Unit Extension (AUv3). Stand Alone supports Ableton Link, Bluetooth MIDI, MIDI IN/OUT and audio file export. The synth features two oscillators, two ADSR envelopes, a high pass filter, a low pass filter and an amplifier per voice. The oscillators are capable of wide variety of modulation to shape the sound. The low pass filter is modeled on cascaded OTA filter circuit for classic analog sound. The Effects include delay, chorus, flanger, reverb, eq, and compressor. The sequencer offers ability to program 16 bar pattern per clip for total 16 clips and parameter automation. Project files can be saved in iCloud Drive to work on iPhone, iPad and Mac. Main Features Virtual analog 8 voice polyphonic synthesizer Sequencer 16 bar patterns per clip. Total 16 clips. Parameter automation. Audio Export Linear PCM format (AIFF, WAV and CAF) and compressed format (AAC) Support iCloud Drive. Support Ableton Link, Bluetooth MIDI, MIDI In / Out. Support Audio Unit Extension (AUv3) Support Universal Purchase. VAPoly works on iPhone, iPad and Mac. System Requirements - For iOS Devices, A10 Fusion or above is recommended. - AudioUnit Extension (AUv3) requires host application which support AudioUnit Extension. - AudioUnit Extension (AUv3) is supported by Apple Garage Band on iOS and macOS, and Apple Logic on Mac.  For any other DAW, it depends on the application and some of them don’t support AudioUnit Extension (AUv3).
