Announcing BESSIE 1.1 for the NeXT computer ! BESSIE is an interactive teaching and sound editor module on Frequency Modulation synthesis. A step by step presentation is given on the history, theory and application of FM synthesis. BESSIE features real time control of FM parameters and allows the user to hear all changes to the synthesis parameters immediately. The program also features an ability to write soundfiles (.snd files) and score files (.score files). .Snd files are recognized by the Soundplayer.app that comes with each NeXT computer, while .score files are written in "scorefile" syntax, which is easily read by the MusicKit. In addition, both kinds of files can be used to cut and paste to compose an original composition. BESSIE features a graphic sound envelope display which controls the DSP in real time. Bessie can also be used to improvise a musical composition using the FM algorithm. BESSIE requires NeXT system 2.0 Improvements in BESSIE 1.1 include: 1. Changed program name to "Bessie.app" which is totally self contained. Can be copied into any directory (or into mail) and can be run from any directory (includes soundfiles which previously had to be moved to LocalLibray/Soundfiles) 2. Onboard soundfiles have been compressed to save disk space. 3. Rounding limitations on attack time for the amplitude envelope have been eliminated to prevent errors when writing scorefiles with attack times < .1 secs. 4. Carrier Frequency text window is now editable and affects the sound. 5. The main editor window can no longer be closed (so you can't "loose" it and have to restart the program). 6. The addition of vibrato sliders. 7. Alterations in the window on vibrato and FM ...the "lab" experiment is different...to include the vibrato ability. 8. use of the FMvi synthpath which provides a "cleaner" sound because of the interpolating oscillators.
