The Latest Updates
REAPER upgrades are released whenever we improve or fix something, sometimes as often as every few days.
These point upgrades are free to any REAPER user.
REAPER 4.151 has OS X 10.4 and ReWire fixes, and builds on REAPER 4.15's numerous improvements, including support for 64-bit ReWire, bridging 64-bit plug-ins on OSX. There are also extensive usability improvements to REAPER's track and region managers, and to the project bay.
ReaTune, REAPER's included pitch analysis/correction FX, now supports on-demand analysis of the audio source, so you no longer need to play through the audio first in real time.
REAPER will now (by default on 32-bit versions) warn when memory use is too high, allowing you to correct the problem before things go wrong.
The full changelog (which includes other updates not mentioned here) and upgrade instructions are on the
download page.
