____________________________________________________________

With gratitude to clarke68 for the panel design and barcode for the panel pcb layout, we're happy to announce the MFOS Echo Rockit for eurorack.

Shortly, we'll be offering panels, panel+pcb sets, full kits and assembled units for the PT2399-based echo.

Pots, jacks and switches mount to the panel PCB- no wiring! We'll post the BOM, schematics etc shortly. The original MFOS through-hole PCB layout is utilized in combination with the barcode panel pcb.

definitely interested in this! would love cv control over delay time though. Should be a fairly simple mod?

Most excellent!

Something for the kludge space?

Very much looking forward to this.

very interesting project! Just saw it now because it showed up in ModularGrid wink

But does it work with modular levels? The original runs on a single 9V battery, right?

And the MFOS page says

Grounding issues will arise if the Echo Rockit is powered from one side of a dual supply system. The Echo Rockit's virtual ground will be at 1/2 of the positive supply which will make DC ground matching impossible. I think issues involving smoking ICs could arise if this advice is ignored. If you know of something I don't on this issue I'd be happy to hear it but I highly recommend the solution shown above in the "Powering an Echo Rockit from Your Dual Supply" illustration.

I see that the 78L05/79L05 has been included in the BOM. So I guess the suggested solution has been implemented (hard to see on the pcb). Does it work well in a modular context?

Any problem if the filter CV is like close to +12V or -12V?

yes, it was designed to incorporate the MFOS circuitry for use on +/-12V euro systems... we're biased of course but love the couple of them we have set up here.

ok, great!

Do you happen to know if there is any problem when the input exceeds the 10V (as I understand, with the modification the Rockit essentially runs on +/-5V, so it should have a bit less headroom than the "usual" eurorack). I just want to make sure I can use it in a system without any thinking.
synthcube
we have not seen any issue, no... thanks
