3.50 and Reaper in Helix Posted November 22 On 11/22/2022 at 5:14 AM, ppoceiro said: There are other reports of Reaper crashing with 3.50 Native. Check the dedicated Native forum. https://line6.com/support/forum/90-helix-native/ I'm having crashes in Reaper also. My Reaper crashes when playing, not when inserting Native. It crashes when Native receives midi input from another track, for snapshot changes or other parameter and only if Native window is visible. If I close the window it doesn't crash. Only happens since 3.50 update. Do you have any midi hardware connected to reaper? Or midi tracks? Is the track where you insert Native receiving any sort of midi instructions? Unrelated to midi, maybe your Windows Security is protecting the folder where the vst or the rest of native is installed. Check if the controlled access folder is activated. Or maybe get rid of any native install you have. And clean the old and new installation folders. Fresh install may solve the problem. Maybe it's a conflict with both versions installed, a VST vs VST3 conflict or some leftovers from the old version still present. Always backup first. Cheers Ya, I got a footswitch going it all the time (it's part of my template). I'll try removing it. Also, I never keep a VST and VST3 version of the same plugin; just keep the VST3. Thanks.
