sold in six weeks twice as much as the ST version in nine weeks, and that the Mac and PC versions had four times the sales. Computer Gaming World stated "This is certainly the clearest exposition ... we have seen to date" of why software companies produced less software for the ST than for other computers. Audio Plenty of professional quality MIDI-related software was released. The popular Windows and Macintosh applications Cubase and Logic Pro originated on the Atari ST (the latter as Creator, Notator, Notator-SL, and Notator Logic). Another popular and powerful ST music sequencer application, KCS, contains a "Multi-Program Environment" that allows ST users to run other applications, such as the synthesizer patch editing software XoR (now known as Unisyn on the Macintosh), from within the sequencer application. Music tracker software became popular on the ST, such as the TCB Tracker, aiding the production of quality music from the Yamaha synthesizer, now called chiptunes. Due to the ST having comparatively large amounts of memory for the time, sound sampling packages became feasible. Replay Professional features a sound sampler using the ST cartridge port to read in parallel from the cartridge port from the ADC. For output of digital sound, it uses the on-board frequency output, sets it to 128 kHz (inaudible) and then modulates the amplitude of that. MasterTracks Pro originated on Macintosh, then ST, then IBM PC version. It continued on Windows and macOS, along with the original company's notation applications Encore. Applications Professional desktop publishing software includes PageStream and Calamus. Word processors include WordPerfect, Microsoft Write, AtariWorks, Signum, Script and First Word (bundled with the machine). Spreadsheets include 3D-Calc, and databases include Zoomracks. Graphics applications include NEOchrome, DEGAS & DEGAS Elite, Deluxe Paint, STAD, and Cyber Paint (which author Jim Kent would later evolve into Autodesk Animator) with advanced features such as 3D design and animation. The Spectrum 512 paint program uses rapid palette switching to expand the on-screen color palette to 512 (up to 46 colors per scan line). 3D computer graphics applications (like Cyber Studio CAD-3D, which author Tom Hudson later developed into Autodesk 3D Studio), brought 3D modelling, sculpting, scripting, and computer animation to the desktop. Video capture and editing applications use dongles connected to the cartridge port for low frame rate, mainly silent and monochrome, but progressed to sound and basic color in still frames. At the end, Spectrum 512 and CAD-3D
