I decided to post this up in here just cause I think more people that care will see it in here but mods can feel free to move this.

Okay, I got a SP12 bout a month ago and got tired of those stock sounds pretty and I got an easy way to replace them with your own custom sounds.
Note - 808 kicks will need filtered and certain bass notes need filtered. So, if your SP is filterless you might be limited on what you do but any normal SP will be in biz especially with a decent mixer.
All the new sounds will hit multi pitch and multi level just like anything else and if you replace every stock sound in the machine it's like getting 5 extra seconds of sample time.
Power users will probably make new banks for every few beats puttin fresh breaks in and samping the rest of thier sounds normally. Drum sample only cats who sequence the SP with and MPC or software probably don't need to read this.
Here we go...
You will need the following tools:
*EPROM programmer
*IC Puller or similar tool
*27256 EPROM(s)
*EPROM eraser is optional but I recomend it
First you’ll need to open up the SP-12, and remove the 4 chips labeled MS1, MS2, MS3
and MS4.
Now you’ll need to get familiar with your EPROM programmer and it’s software to set up your programmer to read the 27256 EPROMs. While you are saving them to your computer and labeling them be sure to match the checksums to verify that the files were read ok.
IP330 MS 1 IC09 - Checksum E918
IP331 MS 2 IC27 - Checksum E4F6
IP332 MS 3 IC10 - Checksum 91FD
IP333 MS 4 IC28 - Checksum 0850
Before you start opening up these files and replacing the sounds you will need to decide which sounds you want to replace and what you’re going to replace them with. For example, you don’t have to replace a cowbell with a cowbell but whatever you decide to replace it with should be very close to the same length. Below is a list of the sample EPROMs along with what’s on them and the individual sample’s approx length.
MS 1 - EL SNARE .390, RIM .120, COWBELL .120 and TOM .550
MS 2 - BD .140, EL TOM .380, HI HAT .490 and CLAP .140
MS 3 - RIDE .900 and SNARE .250
MS 4 - CRASH 1.170
After you decide which samples you’ll be using you will need to resample your custom sounds to 27,500 Hz and convert them to 8 Bits, in that order.
Then, using a standard audio editor such as Audacity or Sound Forge open or import the appropriate MS* file as…
RAW
UNSIGNED
MONO
8-BIT PCM
27500 Hz
Now, copy and paste your custom sounds to the MS* file OVERWRITING the stock sounds. When you're replacing the sounds be sure that you're overwriting to a space within the stock sound. It doesn't have to be the exact length of the stock sound but it can't be any larger. You'll also want to avoid the peaks at the end of files MS2, MS3 and MS4.
When you’re all done replacing sounds in the MS* file save it and change the extension to .bin so that your EPROM programmer will treat it as a binary file. Burn the chips and install them in your SP. Enjoy your free sampling time. PEACE
