Hi Mike,
that's the first thing I have checked (it's on Enable). Moreover, I think that if this switch would be in Disable position, loading a tape would be impossible (not sure anyway)

The data I see in the changed parameters are still the same than BEFORE uploading the SYX file. It looks like the synth is ignoring simply the valid SYSEX data. If I reload the data from cassette interface, it works (the parameters I have changed are restored to original value)
