the few times i tried it , they were all clipping / too loud.
i tried a limiter on ableton, and kept turning it down but it felt like luck of the draw if it turned out ok.
eventually i gave up and used loopseek/verkbenk/ bonk / other tools on mac directly.
theyre also very very much quicker , as tonverk samples it in real time, the mac tools do it in a fraction of a second or two …
basically. , if you have a computer , do it on a computer … 
also , tonverk waveform had a gap at the beginning , but i was unsure if the start point for the key group was offset (so theres no delay in playing it) or if it was zero …(ie. thered be a gap)…
