I can very easily get my Oxi One MkII (slave) to sync to my Nome II (master) via either DIN MIDI out on the Nome II to the TRS MIDI in on the Oxi, but in some situations I'd like to be able to sync via the analog out of the Nome II to the analog (CLK) input on the Oxi.

I've tried connecting via a TRS cable, which doesn't work, and similarly couldn't get it to work with a TS patch cable. I've tried just about every permutation of the analog (and analog 1 and analog 2) settings on the Nome, with no luck, and likewise played with the PPQ IN and Reset Start/Stop settings on the Oxi, but nothing works.

Has anyone had success with this?

Hi, I haven't tried that yet.
However IMO you need a TRS to two TS cables because Nome's analog out socket is TRS for An.1 and An.2 and standard modular inputs for CV, Gate and Clock on the Oxi are TS sockets. One of the TS jacks of the mentioned cable will be unused in that setup.

Thanks, HappyClocker.

According to the Oxi One MkII manual, tip on the CLK IN is clock, ring is start/stop/reset, and sleeve is ground.

According to the Nome II manual, tip on the ANLG out is clock one, ring is clock two, and sleeve is ground.

So it seems the jacks on both units are TRS.

I just used a multi tester on a TRS cable attached top the ANLG out of the Nome II. Setting analog clock mode to FOL and both analog clocks to '24, I'm getting some unexpected results:

• If both clocks are stopped, there's no voltage across tip and sleeve, ring and sleeve, or tip and ring (as expected).

• If clock 1 is playing and clock 2 is stopped, there's no voltage across tip and sleeve, ring and sleeve, or tip and ring (same as if both clocks are stopped).

• If clock 2 is playing and clock 1 is stopped, there no voltage across tip and sleeve, +1.6v across ring and sleeve, and -1.6v across tip and ring.

• If both clock 1 and clock 2 are playing, there no voltage across tip and sleeve, +1.6v across ring and sleeve, and -1.6v across tip and ring (same as if just clock 2 were playing).

Meanwhile, if I change the analog clock mode to DIN, I get the following:

• If both clocks are stopped, there's no voltage across tip and sleeve, ring and sleeve, or tip and ring (as expected).

• If clock 1 is playing and clock 2 is stopped, there's no voltage across tip and sleeve, +5.0v across ring and sleeve, and -5.0v across tip and ring.

• If clock 2 is playing and clock 1 is stopped, there's no voltage across tip and sleeve, ring and sleeve, or tip and ring (same as if both clocks are stopped).

• If both clock 1 and clock 2 are playing, there no voltage across tip and sleeve, +5.0v across ring and sleeve, and -5.0v across tip and ring (same as if just clock 1 were playing).

This makes me think there may be a wiring or other electrical problem with my Nome II unit, unless it's a non-obvious configuration issue.

Simon, what do you think?

The information that is missing here is the speed of the clock. I would assume 24ppq?

If you set the Nome setting "AnL" to "din" you should get what the OXI expects: 24ppq pulses on the left/tip and a start/stop run gate on the right/ring. Then connect a TRS cable, I would expect everything to work.

If the OXI does not expect 24ppq pulses but something lower, then you can do the same with AnL set to con, An.1 set to '4 (if OXI expects 4ppq for example), and An.2 to run. In this case the right/ring output will be a start/stop run gate based on the status of the MIDI output 2.

Regarding your measurements, the Nome sends pulses which cannot really be measured with a multimeter. If you want to check if the output works, the only setting that can be measured is the "run" setting: stopped will be 0V and playing will be constant 5V DC.

I hope this clarifies things a bit!

Thanks, Simon!

I've done the following:

On the Nome II:
I've got ANL set to DIN (so the AN.1 and AN.2 submenus don't appear).

I've connected the ANLG out on the Nome II to the CLK IN on the Oxi One MkII with a TRS cable.

On the Oxi One MkII:
Under CONFIG>ANALOG>PPQ IN, I've set it to '24..
Under CONFIG>ANALOG>Reset/Start-Stop (IN & OUT), I've tried all three options: Off, Pulse Reset, and Run-Stop

I confirmed that the Oxi One MkII is set to use the external CLK source. Nothing happens.

Then, I followed your alternative directions and set ANL to CON, AN.1 to of '1, AN.2 to RUN, and set the Oxi One MkII to PPQ IN = 1PPQ and Reset/Start-Stop (IN & OUT). Still nothing.

Finally, I set ANL to CON, AN.1 to of '2, AN.2 to RUN, and set the Oxi One MkII to PPQ IN = 2PPQ and Reset/Start-Stop (IN & OUT). Still nothing.

The only other PPQ setting on the Oxi One MkII is 1PP16, and I don't see a corresponding option on the NOME II.

I also tried the above swapping AN.1 and AN.2.

Any other suggestions?

Thanks,
Adam

When you say "Nothing happens" do you mean the OXI does not react at all when you press the 2 play buttons on the Nome, and/or when you change th tempo?

It could be that your ANLG output has an actual hardware issue but I'd say that is very unlikely (it would actually be the first Nome II to have that issue). My much stronger guess is that something is missing in the OXI configuration. The first config with the AnL=din looks correct, with CONFIG>ANALOG>Reset/Start-Stop set to "run stop" on OXI. But I do not know the OXI so well so something else could be missing.
Maybe you should ask on the OXI forums about it?

That's correct: the Oxi neither responds to transport commands for either of the two start/stop buttons on the Nome II nor reflects tempo changes on the Nome II.

No one on the Oxi Discord was able to confirm the two devices working together but one person had some suggestions, including double checking PPQs (which I did) and suggesting I try syncing to/from another device with the Oxi (which I did successfully--my KeyStep MkII successfully sent tempo and start/stop to the Oxi).

I also tried running the Nome II as the master to my KeyStep MkII. With the Nome II in DIN mode, the start/stop controls on the Nome II cause the KeyStep MkII to start and stop, but the temp doesn't get received by the KeyStep.

If I do reverse-DIN mode on the Nome II (by setting Analog to CON, Analog 1 to RUN, and Analog 2 to '24), the KeyStep's transport keeps alternating between start ands stop in time with the NOME's clock (i.e., if I turn the dial, the speed of the alternation increases or decreases accordingly), though the actual tempo on the KeyStep doesn't update. Not sure if that's a useful clue?

Thanks in advance for your help!

Well I have a keystep (mk1) which syncs fine from the Nome's ANLG output in DIN mode.
Yes "inverted" din mode will give strange results - that makes sense.

Let's try to dig further into why the keystep's tempo is not changing (in din mode): what are your keystep settings?

Hi adambier and Simon,

First: NOW IT WORKS. My Nome sends clock and start/stop to the Oxi via my already suggested 3,5 mm TRS to two TS cable. One TS jack is unused.
Important to consider: Oxi's Clk In seems to be TS, but Oxi's CV In is TRS! The manual could be more intelligible there.
I use Oxi's Clk In socket only.

Second, here is how:

Nome settings:
Anl = FOL
An.1 and AN.2 = ´4

Oxi One MKII Analog settings:
PPQ IN = 1PP16
Reset / Start-Stop (IN & OUT) = PULSE RESET

Hope that helps many.

Hi HappyClocker and Simon,

Simon's method works for both the Oxi One MkII and the KeyStep MkII!

I've further simplified it down to the following requirements:

• One must use a TRS-to-TS splitter cable (or adapter). Only the tip+ring TS side of the split (typically red or black) can be used.

On the Nome II

• AnL must be set to FOL.

• It doesn't matter what An.1 is set to. It can be OFF, or whatever you want to use for MIDI OUT 1.

• An.2 can be set to any PPQ (24PPQ is most common--if you want to use 4PPQ on the Nome, you must indeed use 1PP16 on the Oxi, as HappyClocker noted).

On the Oxi One MkII

• PPQ In must match An.2 on the Nome.

• Reset/Start-Stop must be set to Pulse.

• And, of course, the clock source must be set to CLK (or INT, which gets overridden when a clock is present elsewhere).

What's a little confusing to me is why I can't simply use the other side of the split (TS corresponding to TS on the TRS) for An.1. Is there some difference between the two analog clock outs? Or does the An.1 side need to be wired differently?

In any case, thanks again to both of you!

Adam

Hi Adam

Well done on sorting it out

This works, but basically you skip the "start run gate" but instead tell the OXI to start and stop automatically when the pulses start and stop (which happens with AnL=FOL, i.e. Follow, i.e. pulses are on/off according to the play button)
And yes it should definitely work whether you use An.1 and left/tip/black plug, or An.2 and right/ring/red plug (as you are doing now if I understood correctly). The hardware for the left and right part of the plug (aka An.1 and An.2) is identical.

On top of this, it should also work using the other side of the plug as start gate (either in DIN mode or with An.2=run). But maybe there is some settings on the OXI side we are missing. We do not have an OXI to test it with unfortunately, but I have sent a Midronome to Manu (creator of the OXI) a while back. So if you ask their support they can probably try it out, making sure the two devices can speak to each other.

Thanks, Simon!

Based on your comments, I think there might actually be a problem with my unit, or an undiscovered firmware issue:

I just added a Mordax DATA module to my rack, which contains an oscilloscope. When I use a TRS split cable and connect the analog out on the Nome II to any two of the four scope inputs on the DATA and start both clocks on the Nome, the right/red/ring plug yields a square pulse wave on the scope but the left/black/tip plug doesn't.

Stopping and starting clock 2 causes the pulse to disappear and reappear, but the clock 1 button doesn't do anything, and I never get a pulse for that side of the split cable.

FYI, I've tried swapping the scope inputs to make sure there isn't a problem with the DATA and have tried a couple different split cables to make sure there isn't a problem with the cable.

Also, to confirm, my settings on the Nome are AnL = FOL, An.1 = '24, and An.2 = '24.

Is this behavior indeed unexpected? I would think that if the HW for An.1 and An.2 are identical, and they are set to the same setting, both would yield the same square pulse wave.

This would of course also explain the strange behavior with syncing to my Oxi and my KeyStep.

I can email a photo of the scope display if you like--not sure how to upload it to this forum.

Thanks again,
Adam

You're all correct Adam this looks like a hardware issue on the Analog output 1 in your unit. And yes that explains the strange behaviors
