Latest versions from MWAV and MW2E are sporting completely redesigned additive synthesis with Fourier transformations, complete with Magnitude/Phase control for all User Waves.
Due to problems with the update process from within the applications, the latest versions can be downloaded as disc images from the website. Check the md5 hash for security concerns.
The new versions have the following features/bug fixes:
Improved wave control table editor for editing waves
Remember Upaw values from last session
Unfortunately, the robot wavetable generation in MWAV does not work on macOS 13 Ventura, but I hope that Apple will fix the bug in the Text To Speech engine soon.
New feature: A palette (Sound Program Vault) for organizing sound patches has been added to the main interface. Single sounds as well as whole sound sets can be imported via drag&drop and copied to an opened library.
All editors have been updated to 64-bit only versions for MacOS X 10.7 (Lion) up to 10.11 (El Capitan) and can be installed from within each application by selecting the “Check for Updates”-menu item.
Legacy 32-bit versions for Mac OS X 10.6 (Snow Leopard) are available as separate downloads from the website.
