I can read instructions just fine, I’ve been using C6 since it first became available, I’ve used it with all my Elektron machines, so you can be confident that I know what I’m doing, I have been a beta tester and preset contributor on 3 Elektron machines, I was one of their first customers, and I have probably spent more on their fantastic machines than most, I never stated anything about promises being broken those are your words. But I do not feel they owe me anything, other than properly working gear, as they always have.
C6 when transfering a large number of samples to Rytm is not adequate, it hangs, yes it often works when doing a few samples but it can take a long time, yes using I’m USB and yes samples are in correct format. You can use the search on the forum and find other people who are not having success with C6 and Rytm.
I fail to see how any of this is factually incorrect.
Elektron have said that transfer will be compatible with Rytm mkI after an OS update, if they were not aware of the C6 issues which you appear to think are false, why would they bother wasting the time to do so?
