I'm a software engineer and long time SP-1200 user (used a 303 for a while before that too), and I'm currently working on a modern clone of this classic machine, based on a raspberry pi.

I made some pretty good progress so far.
I've got most of the basic features like multi-pitch, multi-level, channel assign, chopping, and more already done, as well as a barebones 24ppq sequencer.

I also managed to reverse engineer the exact pitch-shifting algorithm of the SP-1200 (which is what gives it most of its characteristic sound). Many SP-12 & 1200 users have been fooled by a blind test I posted in the FB group between sounds sampled in the SP vs. my emulation
.
Example breaks & samples ran through my emulation here
And a video comparing the emulation to the real thing: https://www.instagram.com/p/Bs_sOVlFVZf ... 2bnnc6vyhf

Shoebox protoype for your entertainment:

Some of the updates I have planned over the original design are:

Let me know what you think, would this be something you'd be interested to see available?
I mainly wanted to make this for myself as a travel/gig portable SP at first but there seems to be some interest so I might find a way to get some units made and distributed.

SP-1200 prices have really gotten out of hand these past few years, this could be a good alternative if you've never experienced how amazing the workflow is on this machine.

With how much SP-1200 cost nowadays I'd definitely pay a decent amount for something like this, especially because it's portable.

Thanks y'all, I appreciate the feedback.
I posted a new vid showing the chopping function in its current state here

Just Blaze actually commented on it saying he wants one, I was pretty stoked.

If you have any suggestions for features you'd like to have on a machine like that please let me know.

real pitch is featured inside yet, so, did the machine come with internal fx (what?)

I'm not sure I understand your question right, but yeah there will be some internal fx. I have already implemented variable bit depth from 1 to 12bits, and Low-pass & Hi-pass filters.
There's a video on my IG of the variable bit depth.

I'm very interested in this project.
Do you plan to sell complete units or kits later, or release the plans in the future?

Thank you. Most likely both assembled units and diy kits will be available. Both the hardware and the software might be open sourced, but that's still up for debate.

Hey I love it, I tried a looper project with the Raspberry pi but ran out of time and brain cells to finish it, hope you don't suffer the same fate ..lol

Any way continue the good work !!!
