Nome II > Oxi One MkII via Analog Sync

[adambier]

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.

EDIT: My assumption was wrong. Correct is: Analog Clk In/Out on Oxi One is not TS but TRS!

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?

I've got it. I was wrong and you are right. I've just added a corrective comment to my post.

Let's wait for Simon's reply.

Hi

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

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?

[adambier]

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!
