Reaper v4.5 RC13 [rev.74033d] PreRelease x64|x86 – PORTABLE

This is a portable pre-release build of the Reaper digital audio workstation, version 4.5 RC13. It is intended for testing and evaluation, giving hobby producers an early look at fixes and tweaks before the final release. The update focuses on MIDI editor improvements, including corrected editing of loop end markers, better redraw of secondary items after undo, and the ability to split notes across multiple MIDI media items. It also adds a metronome preference for choosing the default output and improves JS effects that define only input or output pins. The package includes both 32-bit and 64-bit Windows executables and three additional themes: Pro x-Tools 1.0.1, WT Imperial, and WT Dead Ringer Colonial 4000 XL Pro. This build is suitable for Windows users running FL Studio, Ableton Live, or Logic who want to explore Reaper’s workflow and test the latest changes. As a pre-release, it is not recommended for critical production work, but it offers a useful way to try new features and provide feedback.
