there is no reverb select in rematrix and it is use as a send effect. I report this bug overloud, the rematrix developers. they told it is a bug in reaper. I see no other plugin that have this problem in reaper. Rematrix work in loop play in cubase and other. i told them that breverb(a reverb they have writen too) have not the problem in reaper. they do not answer then. so i thought they fix it. they release some days ago now a new version, problem is in too
maybe overlould do something wrong or in reaper is something wrong ?. see video. to test there is demoversion of rematrix available
