Pure Data vs Vital

Pure Data (Pd) is a free graphical programming environment for combining media processing in real time. Its patch-based workflow supports audio and graphical processing, and it runs on Windows, macOS, and Linux. Artists use Pd for visual arts, theatre, dance, audio, installations, performance, and media art. It can also control hardware and electronics or develop interfaces for other programs. Pd's built-in Deken package manager installs external libraries that extend its functionality. Deken is mainly intended for Pd vanilla, though some other Pd flavors, including Plug Data, can use it. Package listings specify availability for macOS, Linux, Windows, or source compilation, and some packages are limited to particular architectures. Users can find a library or object and install a downloaded DEK package through Pd's Find externals tool. The listed plan is free; no paid plans or usage limits are stated.

Vital is a spectral warping wavetable synthesizer for Linux, macOS, and Windows. Its oscillators reshape wavetable harmonics through stretching, shifting, smearing, and skewing to create timbres. Users can make wavetables by converting samples with pitch-splice or vocode, editing tables, or generating them from text. Modulation includes drag-and-drop assignment, audio-rate modulation, stereo-splittable and keytracked LFOs, and custom envelope curves. Sound tools include two routable voice filters, eight routable effects, an oscilloscope, and a spectrum viewer. Vital supports MPE and microtonal tuning files, with VST, VST3, AU, and LV2 plugin formats listed. Requirements include 64-bit operation and OpenGL 3 or higher; the listed systems are Windows 10+, macOS 10.15+, and Ubuntu Linux 18.04+. The free Basic plan costs nothing and includes 75 presets, 25 wavetables, and full synth features. Plus costs $25, paid once and includes 250 presets and 70 wavetables. Text-to-wavetable requests are limited to five per day unless a plan unlocks unlimited requests.
