I posted that he should check he was sending the data at '1987 speeds'
earlier today, but deleted it when I re-read that it was giving the error the SECOND he turned on his sysex app... now unless it's trying to dump data straight away (automatically) then I shouldn't be that? I know some apps send SYSEX as they are run (i.e the 'clever' scrolling messages on the SYnth display) and maybe it could be that but - is he even getting to initiating an actual DUMP yet?
If it only occurs on dump attempts then yes, slow the transfer speed right down.
