Connection problems

Post by Dtscape50 »

Really hope someone can help. Borrowed an Edirol pcr-800 of a friend. Using a macbook pro with Big Sur, latest upto date os.
So I tried uploading the correct driver for the keyboard. Nothing showed on my audio/midi page. After several failed attempts I thought I'd connect it through a normal midi cable into my presonus audiobox. Nothing worked. I know the midi works on the presonus as I've used other controller keyboards through it. I even tried the sys08 midi through USB off on the edirol... that didn't work.
I then made a big mistake of trying to update the keyboards software, currently 1.03 version. But I suddenly realised the computer can't see the keyboard to send the update...
I now have an error 'fff' code that I can't exit out of.

Can anyone help?...


Please its driving me nuts!!
Thank you in advance.
