It’s amazing what you can learn just by reading the manual, or if you prefer: RTFM.
It’s also amazing what you can find in an online PDF that should be in the manual, or SBINFM.
The online manuals for my equipment (plus any other useful device-specific info) can be found here. Useful to read before you make a purchase, so you can be sure to know what you’re paying for.
KORG DS-10 – can’t find this one! But I’m working on it :-)
