Soundshaper – CDP GUI Compatible with PC ONLY

Soundshaper is a 'front-end', meaning that it accesses and uses the underlying CDP sound transformation and editing programs. Therefore, please note that the CDP sound transformation and editing software must be installed as well as Soundshaper.

The new and updated Soundshaper (4.4) is now available free of charge. It is fully compatible with CDP Release 7. Soundshaper Lite and Soundshaper Pro have been discontinued and registration is no longer required.

Note that this move to a free download of Soundshaper makes CDP almost completely reliant on donations in order to cover its annual running costs. Please try to make a donation if at all possible.

Soundshaper can be freely downloaded from the CDP Downloads Page or from Robert Fraser's website

Soundshaper has several important features:

  • Create multi-process patches in a simple grid structure
  • Designed for multi-channel work, with 16 grid rows which can process up to 16 sounds independently.
  • Save and recall patches, or run with different source files
  • Re-edit patch cells or replace with alternative processes
  • Automatic conversion of CDP file types
  • Almost all CDP processes can be run with multi-channel input

Additional information is given in the Soundshaper PDF information page (see link below).

Compatible with PC ONLY

ProcessPack is a GUI-driven package of sound design modules that are complementary to the CDP system.

  • ProcessPack is now available for download after purchase. You will be sent a link automatically.
  • ProcessPack is an umbrella program for a number of (projected) high-level composition modules.
  • DISPERSAL combines a number of CDP's sound processing programs with algorithmic scripting to make it possible to compose by working directly with a musical design template, such as the dispersal or gathering together of sonic events.
  • Other modules are PlayMix a module that enables you to mix and audition soundfiles in real-time, and Pyramid, which layers sounds with shape presets, MidiFileReader which will load a standard MIDI file and realise it with a soundfile that you select, Sonify which will turn data into sound, and Shimmer, which is hard to describe.
  • Follow this link for more descriptions of ProcessPack modules.
