Yamaha SY85 Synthesiser
The Factory Restore Floppy Disk
Changing the battery on the Yamaha SY85 will cause the synthesiser to lose its internal settings. Which in simple terms means the internal voices and performances.
Losing the internal settings on the SY85 is another indication that while the SY85 carries the SY designation it is different from the SY77 and SY99 which are both able to load the factory sounds from an internal ROM if required.
So my advice to anyone that is going to change the battery on the Yamaha SY85 is back up the voices and performances that you have loaded or created prior to removing the battery. If you do not undertake this task, then once the battery is removed you will loose anything that is stored in the memory.
But you get to those instances where for whatever reason you have lost the internal voices and performances and just need to reset everything back to the way the synthesiser was delivered from the factory.
In this instance you have two choices:
Find a copy of a SYSEX file on the internet and I am sure that there are some of these floating about in the user groups.
Obtain a copy of the Factory Set disk. Simplest method to restore the SY85 and my personal preference.
Why do I favour the second method over the first. For me it is the simplest way to perform the restore process.
Put the Factory Disk in the Disk Drive
Press the utility button and then Disk from the Sub-mode option
Select the LOAD all option and reload all the Factory sounds
The whole process is done and dusted in under a minute. Whereas the SYSEX re-load requires a computer to be setup, setting up all the MIDI connections, setting up the connection parameters, setting up the synthesiser to receive the data etc... It is just more hassle.
If you are having trouble finding the Yamaha SY85 factory disk I can send you a disk with the factory set on it. The disks are available on E-Bay. The disk will be tested in my Yamaha SY85, which has had its floppy drives recently refurbished prior to despatch.
