Title: CHEETAH MD8 Drum Machine Manual (PDF) + Sound data WAV's
Post by: SynTeknik on November 06, 2009, 05:39:38 PM
Since I can't delete the first topic in a thread, I'll have to just overwrite it.
Gone.
If I've pissed anyone off by offering the item for sale, then I apologise unreservedly.

However, I take hacking attempts very seriously indeed...  


(EDIT by admin: added 'sound data WAVS' to thread title)

erm, i think you might have mis-judged the spirit of this forum.

You've found a rare manual but you are wanting to charge people £7 to look at it?!!!!
Do you want to take this post down before your karma goes through the floor or shall i?  ::)

Oh, and posting the same things on more than one thread will just get your duplicate posts deleted

well the public have spoken. This post has been reported several times and your karma doesn't look too healthy so i'm taking out that link. If you want to repost the manual for free then i'm sure we'd all be grateful.

Hacking attempts?

What?

I don't think the issue was with offering something for sale in general, i think the issue was with offering something for sale on a forum dedicated to sharing free information, when the thing you have for sale doesn't actually belong to you anyway. Its more than a little bit cheeky.   :-\

Do you have all the sounds that actually work? I think the wav's i had had a couple of sounds missing and you'd have to try to load them in about 10 times for each sound before it actually worked, either that or the MD8 i had was just very very picky about input levels. I just gave up after spending about an hour just getting a few sounds loaded in.

Can you upload them somewhere? Or i can host them on the circuitbenders server if we've got room.

Hi. I've now sold the non-working MD8 via eBay. So I never got around to fixing it or re-loading sounds.

I have to say that I don't think offering the PDF of the manual for sale is in the least bit cheeky, as I had to a: buy an MD8, and then b: scan, tidy and pdf the images. So I had invested time and money. The manual really IS rare, and people are prepared to pay a fair price for these things. (Trust me, I know).

However, I do understand that's not the ethos of this place.. This place is all about helping each other out.  

So, in that spirit, here it is: Cheetah MD8 User Manual (http://rapidshare.com/files/318364359/md8-manual.pdf.html)

Rapidshare will allow 10 downloads, and the file will be removed in 90 days or so.

Many thanks to "wul" for uploading the WAV files.

ahh, but just because people are willing to a pay a price for something does that automatically mean you should charge it?
Its a bit like holding people to ransom isn't it? On many occassions i've needed a service manual for something only to find that the only place i can find it is someone on the net who somehow feels justified in charging me £30 for a 5 page PDF, simply because it is rare and i have no other option! Well, apart from just not buying the thing of course, which is invariably what happens so whatever it is goes unrepaired.  :-\

Is it possible to actually make a living simply by owning manuals?

Anyway, before we get bogged down in the complex philosophies of manual sales, thanks for putting that up for download.  I'll stick it in an archive with the wav files and upload it to our server when it finally decides to let me upload anything.

Somebody give that man some karma  ;)

We'll just have to agree to disagree!
Karma's looking better, though.

has anybody managed to save any sytem exclusive voice data from the md8, when i try it i get a  "err voice copy" message, one thing i have found is that if you disconnect the battery for just over a minute, the sample data starts to corupt and distort,
another thing the wav files i uploaded load every time when fed out of the headphone output on full of my mixer.
the system ex data would be usefull , to reverse engineer the data and and be able to load any sample.......maybe

Has anyone still got a copy of this manual? Mediafire kindly deleted it from my account and i don't appear to have a copy on my hard drive.

It came through fine as an email attachment, cheers for that.  ;)

I've uploaded the Manual and the WAV file of the sound data here if anyone needs it: http://www.mediafire.com/?u9d83bjkj850sfy (http://www.mediafire.com/?u9d83bjkj850sfy)

are you able to dump the wav data as midi?

I actually spoke to one of the original Cheetah design engineers about this a while back and his response was something along the lines of 'its a piece of crap, it never worked properly'

Make of that what you will. I ended up selling the only MD8 i've had through sheer frustration at nothing working the way it should. I never managed to get anything other than the most basic functionality to work right, certainly not any kind of sysex dump.

I don't think its going to be an EPROM problem and i very much doubt that even the original designers have a copy of the data file. Why would anyone keep it? I'd imagine the only place to get a copy of the EPROM would be from someone whos got one with a programmer to read it.

The MD8 is such a piece of junk there could be dozens of things wrong with it. Check the internal backup battery for leaks and look carefully for dry solder joints and cracks.

I think the battery is actually missing on that board, which might have something to do with the problems you are having. That would indicate that someone has removed it as it was leaking. The brown stuff around the pins on the chips and the damage to the tracks on the bottom left of the first photo would certainly suggest a battery leak.

From the look of it the battery was meant to solder into those three empty holes on the lower left where something has obviously been removed.

I wonder if you could replace the sample RAM with a ROM chip?

Does anyone still have the Manual and samples for this?

Rapidshare doesn't work these days.

Thanks for any help :-)

Theres a mediafire link to the manual and wav of the sound data at the top of this page.
