1. Does it work well with external controllers for editing?
2. Are there only Preset patches that you can modify or can you make your own?
2a. If the former is true, would sysex be a good idea for patch storage?
3. I've read a lot about the RAM battery usually needing replaced after a long time. I know absolutely nothing about soldering so should I get someone else to replace the battery for me or is it easy enough to do yourself with basic knowledge? It looks pretty simple and I'm a very detail-oriented, careful person when it comes to repairs of any kind.
4. In the event that it does not come with an adapter, what kind should I get?
5. Anything else I should know about it?
Thinking of asking $200 if it works properly, $100 if RAM battery needs replacing.
