Siren Audio has announced version 2 of its Generative and Feedback software applications for generating evolving soundscapes with granular synthesis and creating dense textures and loops.

Released in June 2011, The original Lorelei suite comprised of three applications that aimed to reduce the amount of times it took to generate new musical ideas and audio material.

After receiving awards from Computer Music Magazine, and a favourable review from Sound on Sound, the developer worked in stages to create the new versions of the original Generative and Feedback applications.

The new applications retain the same core ideas of generating drone and loop based audio material via delays and granular synthesis, but give much more control to the user over how the sound is created.

Siren Audio Generative 2

The Generative application has received the biggest overhaul, with a number of new features that make it a significant tool for generating evolving soundscapes and drones. Perhaps the biggest change is the ability to save and restore sessions, allowing the user to create complex sounds and restore them. The four granular players can now have independent pitch and filter settings, and a new ‘states’ dialog allows the user to save up to sixteen states within a preset that can be switched between.

Changes in Generative 2

  • Restore sessions. Recall analysed audio with all settings to completely restore a previous session.
  • ‘States’ section to alter parameters via MIDI notes and the computer keyboard.
  • MIDI trigger section with amplitude envelope to set pitches and change state presets.
  • Ability to change each devices pitch using a sliding scale or keyboard values.
  • Graphical filter for each device, and a choice of state variable filter or graphic filter for the main output filter.
  • Improved user variation implementation for more precise variation control.
  • Aux send to effects for each device.
  • Effects channel with delay ramp, distortion, and delay effects.
  • ‘Random segments on copy’ function to bypass the previous version’s analysis stage.
  • ‘Random Segments’ window to quickly create new segments, with space and length settings.
  • User options for CPU reduction: hide graphical playheads / set number of voices used by each device.
  • Direct control of granular parameters by suspending the applications internal synthesis engine.
  • ‘User Playback Area’ for each device in order to give finer control of user playback position via MIDI.
  • Global Pitch tuning and variation settings.
  • Random pitch method by user defined scale or pitch range.
  • Option to alter pitches via MIDI by scale / range / keyboard interval.
  • Ability to view, add, edit, and delete segments.
  • Option to show segments of specific devices and/or user playback areas.
  • Better sounding state variable filters (by Tim Place of 74 Objects).
  • Reverb (by Tim Place of 74 Objects).
  • Ability to scale the application, for laptops with small screens.
Siren Audio Feedback 2

Feedback has had many refinements internally to save CPU usage, and features new audio file playback modes which allow users more creative freedom when manipulating audio files. The delay times can now be controlled via MIDI, as well as the input and output effects, which further enhances Feedback’s capabilities in as a live performance tool. Also included with this update are improved filters and a new reverb effect.

Changes in Feedback 2

  • Expanded Random Settings dialog, with random delay times based on millisecond or measure ranges.
  • Improved Granular synthesis play mode.
  • Polyphonic Sampler file playback mode with up to 10 voices.
  • Output Effects Section.
  • New ‘Play Free’ playback modes for interesting pitched playback of an audio file.
  • Darker/Refined User Interface.
  • Reverb (by Timothy Place of C74 Objects).
  • Improved state variable filters (by Timothy Place of C74 Objects).
  • New Instability and Strength controls to control delay time variation parameters.
  • Various user interface and internal changes to save CPU usage.
  • More parameters controllable via MIDI.
  • Ability to change the order of Output Effects / Reverb.
  • Visual Feedback of BPM for live performance.
  • More options for recording input source.
  • Ability to scale the application, for laptops with small screens.
  • Ability to Update / Delete Preset slots.

Generative and Feedback for Windows and Mac are available for purchase for £30 GBP and £25 GBP, respectively. A bundle of both is £50 GBP. Users who bought the software after February the 14th 2014 will receive a free upgrade, and users of the first version of the Lorelei suite will receive a 50% discount on the new applications.
