Thanks for the help … it’s all much clearer now. Should have RTFM I guess! Now if only C6 would cooperate! Tried to download the Reshaped Harmonics sample pack but the download failed every 4 or 5 samples. Took forever doing it in multiple batches. Used the settings shown in the above video, with the supplied usb cable connected directly to the back of my iMac. Turning off turbo works perfectly except it is painfully slow.
I have had very few problems with a MacBook Pro retina. I usually make sure to shut both the rytm and my mac down before I connect them and do sample transfers. Hopefully overbridge will bring better results soon.
