I feel like I'm creating a series of DIY articles here about recouping your investment from 20-some years ago..
But seriously, I have heard from several people on my previous article on the D-20 backup battery change ("related link", at the bottom of this post), so I figured I would post this tip as well since there are precious few resources for older electronic instruments, and even less for this venerable keyboard.
I was recently looking around online and found a great resource, a freeware SysEx Librarian program for Macintosh OS X (http://www.snoize.com/SysExLibrarian/). I use an old Macintosh Powerbook running OS X 10.4 and an Edirol UM-2ex MIDI/USB interface for swapping out kit sets on my Roland TDW-10 setup with VDrumLib. So I had visions of being able to do the same thing with my D-20 patches and tones, which seemed pretty convenient!
I went through the whole SysEx load on the keyboard after turning memory protect off, and after it finished, the keyboard was locked up. I turned it off and tried turning it back on. It started up, and then the display screen went dark. Not blank, but dark. I attempted a reset/initialize by holding down the TUNE/FUNCTION and WRITE buttons on startup, but after the initial startup screen on the keyboard it displayed something troubling:
So my first piece of advice: don't panic! You can try another restart, but it will yield the same dark display screen. What's going on?
The problem is that if you have a D-20 model with a ROM version of 1.03 or less, when attempting a SysEx dump you will have this lock-up and will have to jump through a few hoops to fix it, which I will outline below.
You will have to open up your D-20 and remove the backup battery. You will find instructions and some warnings on this in my article on removing the backup battery in the link below. What's happening is that the keyboard is experiencing an error that locks it up, but it is such a serious error that the backup battery actually preserves the bad data in the keyboard memory which perpetuates the error. Removing the backup battery clears this and breaks the error loop. Leave the keyboard without the battery for 5 minutes or so to make sure it does clear the memory. Please also be sure that you have the keyboard unplugged before taking the bottom off.
After you replace the backup battery and replace the bottom cover, plug it in and hold down the TUNE/FUNCTION and WRITE buttons when you turn it on. The keyboard will initialize to its initial "New Out of the Box" state and you will be able to perform a restore of your settings, tones, timbres and patches, which you will need to do since the memory has been wiped by removing all power for the backup for the keyboard.
To safely transfer MIDI dump info to the D-20 with an earlier ROM chip, you will need to use the "ONE-WAY BULK RECEIVE ALL DATA TRANSFER" mode on the keyboard. Check the manual on this one...it's not difficult, but it is an extra couple steps compared to modern plug & play.
So there is still hope. Incidentally, here are all the combinations of startup modes that you can initiate by holding down function buttons as you turn the synth on:
TUNE/FUNCTION + WRITE: initialize the D-20
EXIT + EDIT: memory test
EXIT + TUNE/FUNCTION: controller test - shows bender value, etc.
EXIT + MIDI: keyboard test - shows key and velocity
EXIT + COMPARE: D/A adjust and PCM test; band buttons play PCM sounds for D/A setup
EXIT + ENTER: lamp test - all the lights blink
EXIT + PERFORMANCE/MULTI-TIMBRAL: floppy disk test

( 3 / 65 )So let me preface this by saying that I am a bit of a Red Wings fan as well. but my loyalties lay with the Sharks and the Wild. So:

This is just awesome. I actually saw this on the game last night and thought it was pretty cool, although we're now getting heat from the Wings press and fans for "copying" their tradition. In response, all I have to say is that we got our sharks locally from the SF bay; let's see you guys pull an octopus out of Lake Michigan.
Go Sharks!

So technically my first instrument was the piano, but I gravitated to drums pretty quickly, and stuck with it for quite a while. After moving, I dropped it for a while, mainly because I sold my entire kit to pay for moving expenses and getting a deposit on an apartment.
Recently I've been getting back into music, and while looking around at acoustic sets, I found the kit pictured multiple times in this post. Here's some more info on the "real" setup:

Unbelievable. This would match the size of my old kit, but being sponsored and designed by my personal all-time favorite composer, drummer and percussionist, I could die happy if I got some of this.
Just sit and watch the finish on the drums. Wow!
