Hello Joakim, I have a JX3P without the PG-200. I'm interested in building your MPG-200. Is this project available as a kit and is it possible to see your final h/w project?thank you
Hi! The MPG-200 is mostly SMD components, and all the magic happens inside a microcontroller. I have no way of programming the microcontroller without soldering it to the PCB with 50% of the other components, so unfortunately no kit is available at this time.I would be more than happy to sell you a completed one once I get the circuit boards (I ordered them yesterday but they take a while to arrive). The current version has no enclosure so you have to source one yourself if you want it inside a box.I don't know if you've read my other posts, but you have to be aware that the MPG-200 is not a replacement for the JX-3P kiwitech-upgrade. It replaces the PG-200 but doesn't change the JX itself, which means that you still have to switch between the programmer and midi in. I have made it possible to automate the switching so you can run both midi and PG-200 signals through the same midi cable, but it still takes a bit of time each time the JX switches mode so playing the JX through midi while tweaking it using the MPG-200 will not be ideal.That said, as a PG-200 replacement it will work great and give you all the functionality of the PG-200 using any other midi controller.PS: The hw is very similar to the one in this post: http://atosynth.blogspot.no/2015/05/mpg-200-hardware-verified.html - a few components have been removed but the form factor (70 x 22 mm approx) is the same.PPS: I first posted this comment separately but moved it to an answer to your post now in case you didn't read it.

Joakim, so the potentiometers & switches will be separate from the MPG200 processor board? ...the potentiometer board could be a kitwith a bit of drilling, It would be interesting to have the knobs mounted on the JX3p panel itself, not on an external box.. more like the juno-106. anyways, let me know what the price would be. Thanks and congrats on the new baby girl. I have a daughter as well, so I'm a proud daddy.. take care
Yes, the MPG200 is intended as a converter between a midi controller (box with pots and switches) or a DAW and the JX-3P.It would be possible to build a separate pots board but I would have to modify the MPG200 to read the pots. Not a very big task, but the PCB to solder the pots to would cost quite a bit in small quantities. The pots, potmeter caps and switches will cost a lot too, so a kit would end up being quite expensive. To be honest,you may be better off buying the Mode machines PG-200 clone and use that if you do not need the midi input.I'll keep you updated about the price etc.It would love to have the knobs mounted on the JX-3P as well though, looks very cool!Thanks btw, I am indeed a proud daddy too. It's a lot of work but it's so rewarding as well :-)
Hi I also have a jx3p which I have almost finished renovating and a pg200 type interface would be great to biulkd into the synth but when I tried to download the pg200 protocol files, I get the error 404 type message for no files existing?? Is there a way for me to get these files? Thanks. Carl
Hi! I am not entirely certain what file you are referring to. I have not made the source code and board design for the mpg-200 publicly available, but the decoded protocol can be found at my site here: http://xonik.no/mpg-200/pg-200/pg-200.htmlI intend to sell a populated but unboxed version, the one in the picture in this post: http://atosynth.blogspot.no/2015/05/mpg-200-hardware-verified.html. If you want one without the midi socket attached for easier installation that is of course also no problem. I am looking for someone to beta test the mpg-200, and the person will get the device at a slight discount. Contact me at tysseng at gmail if you are interested.
