a legend is back...System-700 in eurorack

Post by Modulart_JP » Tue Jun 04, 2019 9:34 pm

Hi all !
Happy to introduce the new Pharmasonic SYS-700 series.
:nana:
All modules are true clones of the Roland System-700.
10 modules are available already as DIY projects.
:goo:
The fist batch of PCB's and front panels is available for pre-order now in my shop:
https://www.pharmasonic.jp/shop/index.p ... r=category

Pre-orders will be closed on June 30.
Don't miss this chance !

The BOM's as well as DXF files for the panels will be online very soon.

A quick look at the PCB picture would indicate otherwise ?

These look great! Well done!
Are there any awkward components, or are they all fairly easy to acquire?
Could you post photos of each of the PCBs please?
Hoping that each PCB has mounting holes for the non-Eurorack folk...

1st off...
All BOM's and front panel DXF files are now available on the PCB's pages.

Instead of uA726, the VCO uses the "discrete" circuit that I used for my SYS-100 VCO clone and it works very well.
The only drawback being that the VCO needs a bit more time to be stable.

I will take pictures of each PCB next week.
I have plans to make Moog/DotCom versions of the modules.
The PCB's should be more non-euro friendly.
Some components are obsolete but still possible to source.
I have local suppliers that still carry them and I'll be able to offer some of them for sale in my shop.
For the very few components impossible to source, I designed the circuits using easy to source replacement.

Looking good, if I can get the spare cash I'm well up for this build. Great job. :yay:

Added a link to a Mouser cart on each module's PCB page.
Keep in mind that the Mouser carts do not include all the parts and you should compare them against the BOM's to see what parts need to be sourced elsewhere.

SYS-700 710 Multiple Jack now available.
It combines both the System-700's 710A and 710B multiple modules into 1.

Added the BOM and DXF for the Multiple 710.
Also, I added a few parts that can be hard to source to the shop.

Beautiful! Love that they don’t depart drastically from aesthetics of other Vintage Roland-inspired eurorack. I prefer putting interrelated systems of modular eurorack together, and it’s lovely when they share colors and visual cues.

Pre-orders for SYS-700 PCB's/panels/modules are now closed.
Thank you to all of you guys who placed an order.
Orders will start shipping next week in the order they were received.
I hope you'll enjoy the modules.

Where to direct parts questions?

Post by wendallsan » Thu Jul 04, 2019 1:30 pm

I ordered a couple of the easier module PCB's and faceplates for the System 700 and am gathering parts for these projects while I wait for these parts to arrive. I hope to prove myself with these simple modules and then if successful purchase more modules to build a reasonable clone of the the venerable System 700 if PCB's are still available at that time.

Thanks very much for providing Mouser project links, that is very helpful in sourcing the parts to newcomers such as myself.

I am not sure what pots to order and am wondering how to best confirm whether a given pot will work with the PCB layout and circuit, and would like to know how to best get an answer without being annoying or redundant. I have built stomp boxes before, but have not mounted pots onto PCB's to date (the stomp boxs' knobs and switches were wired up rather than mounted on the board). I currently plan to build the 709 S&H and 716 Mixer modules.

I am considering these pots for the 9mm 100k linear pots used in the Mixer: https://www.mouser.com/ProductDetail/317-2090F-100K

I am considering this pot for the 16mm 1M reverse log pot used in the S&H: https://www.mouser.com/ProductDetail/BI ... gasyk7zO83

Do these seem like reasonable pots for the job? Thank you for your time.

It looks like that 9mm pot doesn't have a bushing.
It would be better to use pots with one.
The 16mm one looks good.
However, you may want to use pots with all the same kind of shaft so you can use the same kind of knobs for all...

I am working on the build notes and the calibration procedures right now.
:deadbanana:
Also, I am prototyping a new module: the 707 Amp./Env.Follow./Integrator

What would be great after the system 700, is all modules from the SH-05 !

I know the multi mode is already available : a good start !

I still regret having sold my SH-05 20 years ago....

you really want the slow, low output AR envelope?

not much point, you could get a more flexible SH-5-style synth with the System 100 clone PCBs, the SH-5 VCF clone and the Ken Stone CGS30 bandpass.

+1

At last the SYS-700 PCB's have arrived.
After being held by the Japanese Customs for almost a week...
Anyway, sorry for the delay, guys, but things will finally start to ship on Monday.
I am finishing the build notes and I will track down errors in the BOM's (if any) over the week end.
I'll let you know if there is any update.

Thanks very much for looking at the pots and for your thoughts on them. Also great to hear that more System 700 modules may still be forthcoming! If my builds of the 1st 2 modules go well, I will certainly be building more!

Will you be sharing your build notes somewhere soon, as it sounds like PCBs are shipping?

Just seeing this thread.

Will these modules be available again?
