You'd need to trade 3 MPC 3000's to get an SP1200 with the way prices are.

Thanks for the offer but I already have a perfectly fine MPC 3000.
I want an LE , plus cash.

especially online.

Steven Slate was asking what the Hip Hop community needs. I said an SP1200-Mini. Seriously, with all the clones out there, why no one has cloned an SP1200? Q

A good portion of the components have not been manufactured in 30 years. That is why there was a super small run of the 1998 reissue, sourcing the SSM filter IC's is too difficult and the cost of manufacturing them again would cost more than the amount of people that would be buying an SP1200.

Nope the SSM is not the main problem. I guess noone wouldn't mind (or even hear a difference) if its not the SSM2044 but another analog filter and with the release of the "new SSM2044" ...........................http://www.synthtopia.com/content/2017/ ... or-synths/ case closed.

I guess the costs of a clone (just the components to get a machines sound and sequencer) are not that high. The most of the money will probably went into reverse engineering the original OS (I'm not into programming but to get infos out of the OS EPROM and recreating this into a new one might be not THAT easy. But I could be wrong on this and its simply copy and paste the code if the machine has the same components). Printing the PCBs = no problem. Resistors, Capacitators, RAM = no problem. Floppy drive.......well, Gotek is the answer here I guess. Yeah the exact buttons/pads are not available but I wouldn't mind havin rubber pads instead.
And then we have the problem with all the patented stuff. It would be hard to impossible to sell this without the permission of the holders of the patents

That OP-1 is the closest thing. Great crunch.

Peace peter, thanks for the response. You are right, it was another filter. There was a discernible difference from the tests I saw posted online although not enough to make me get upset over. Maybe someone else can chime in about the actual filter that has yet (as far as I know) to be reproduced. Also keep in mind that the SSM was only reissued due to the amount of other instruments that can employ it. So without going deeper into schematics and down the list of components, it would be interesting to determine if the SP1200 can possibly be redone in kit form and the costs associated with it.

With relation to the EPROM - That's just a matter of dumping it. The SP1200 runs off an old Z80 processor which are easy to obtain however a better method would be to get a mcu for $15 that can be reprogrammed over usb (such examples can be referenced with projects on the Prophet 600, etc), runs at a higher mhz and program it to handle the instruction set, which I believe can affect the clock operations as it isn't only up to a crystal for it. The swing that people get from the SP12/SP1200 is due to the slight inaccuracy in the clock.

Now where things get difficult in relation to the OS aspect is since there is no source code (so Emu claims) within reach, it would need to be reverse engineered -- it would have to do with analyzing / dumping the logic before any new functions could be implemented -- which would deviate from having a 1:1 clone made.

Even a knock-off would fly off shelves if done right. Make it up to date with SD reader, USB, expand the memory, add 8 more buttons and just call it the 1200.

Rossum electro asimil8tor is the sleeper here. Had a sales rep bending over backwards getting me info for me.

Not much media out there on it but he was able to get me the manual and it’s clearly the purpose of this new sampler.

Although not the same sonically it will get you about as close as one could get with lots more options.

A way better route tbh than getting a sp, I think. If you wanna dive into modular that is.

The mix out is just an analog multiplexer which will cost you about $1. :hmmm:
