Controller mapping OB6/P-6 to u-he and TAL synths (Reaper): new relative mode

 already published ReaLearn (see below) presets that map various controllers (including OB6 and Prophet-6) to various u-he and TAL virtual analog softsynths, as well as Monark and OP-X Pro.
Now, through one of many new features in ReaLearn, you can control these softsynths with the OB6 or Prophet-6 in relative mode (like "relative pot mode"), so you don't get VST parameter jumps when you control them with the OB6/P-6 knobs.

ReaLearn is a fantastic, free plugin for the Reaper DAW.

You can find more info on the presets here:
They can be installed via ReaPack or manually.
