ruimoreira,
Yes it is possible in a few steps. What you have to do first is...
* Create a dummy pattern (A).
* In Pattern EDIT mode, copy the flash or ROM style from it's location into the dummy pattern (A).
* Now your new A pattern on H. Disk is exactly the same as the one you copied from.
* Insert a FD into the SD1 and using the DISK function (copy), copy the pattern A from HD to FD.
* Insert this FD into the MIDIJAY and copy the pattern A from the FD to the HD/STYLES folder of the MIDIJAY. You may place this in any subfolder within the STYLES folder or in the styles folder itself.
Hope this helps.
Thanks,
AJ
