I've been using the Reaktor 4 beatbox called Massive for many years. I Just upgraded my home studio to a mac mini 4 running OS 15.5. And then i also upgraded to Reaktor 6. I'm only interested in working with my own samples so, today, i spent a few hours trying, but completely failing, to replace the bundled samples with my own .wav files. Massive doesn't seem to recognize them no matter what i try. Another weird thing that's happening, is that even though i replace the original sample with my own on the sample loader, it remains on the track where it had been playing. Even weirder, i'll be dialing in the root of my own sample on a track but instead I'll dial up a sample that isn't even in the sample loader. It makes me wonder. Is Massive corrupted? Anyway, looking for a way together it to work, because it's the main reason i upgraded.
