Image-Line is working hard on FL Studio 10. The just released FL Studio 9.7 Beta version shows a few interesting features, with Pitcher and Newtone as the most important additions. These tools let the user harmonize or change the pitch of audio, for example on vocals. Again with these new features there is a host with a standard Cher effect on board, see also the video beneath this text.
Pitcher and Newtone are paid upgrades. For existing FL Studio users, Image-Line now has a Pay what you want promotion, which lets the user fill in the price what he thinks the plugins are worth, starting with a minimum amount of €9.
