According to a blog posting (translated from original French version) getting increasing interest around the Mac web, Apple's professional audio workstation product, Logic, is being redesigned. The new version, reportedly set to use a different name, is supposedly heavily dependent on Mac OS 10.5 "Leopard" features, and will require the new OS to run. Also mentioned is the possibility of Apple using previous patents in the new version to provide tactile feedback.
According to the site, the revamped version would be launched at Frankfurt's MusikMesse, which runs from March 28-31. However, Apple currently does not plan to attend MusikMesse.
At the present time, we do not feel these claims have much substance, and post them to page 2 for interest's sake only.
Update: While Apple's upcoming events page does not list MusikMesse, it does appear as though Apple has rented out three boths at the event.
