It’s not a proprietary Apple signal, it’s just the wiring of the headset…
That said, this is type of wiring just works for a Microphone input built into the cabling not an external signal.
What I’m trying to make is a TRRS to TRRS cable with a button on it to activate the “microphone in” function that works the same as when a headset is plugged in.
I followed the attached schematic but had to alter it since the destination of the TRRS cable coming from the OP-Z is another TRRS plug rather than two speakers and a microphone… and my cable doesn’t seem to work correctly.
Do I need to add an extra resistor in there to mimic the microphone type of resistance?
I want to connect the OP-Z to the Aux input of an Eventide Mixinglink (this is a bi-directional TRRS jack) and be able to use the OP-Z effects on the output from the Mixinglink.
No it is. Apple and TE do not use the same open-source resistor design that Android uses and that you describe. I already confirmed it and mentioned it in my original post, so I am not sure why people keep trying to contradict me.
As far as I can tell, Apple’s design is very hard to find details on. Luckly @masterofstuff124 found someone who reveres engineered an old pair. Check his link above. Hopefully, Apple hasn’t changed the design since then.
I am reading your link - should have read it before. My apologies there.
The reason I didn’t think it was proprietary is I have an off brand headset (Brainwavz https://www.amazon.com/dp/B00L2459ZO/ref=cm_sw_r_cp_api_i_h2aHCbQ06NQD8) which works just like the Apple headset works on the OP-Z and I assumed that if it isn’t Apple and it works that the design wouldn’t be proprietary.
That suggests that my headset copied Both Apple and android designs - or rather whatever extra Apple requires doesn’t break Android capability.
Due to the complexity of building an arduino board with an external power supply to duplicate the apple style control structure of the headset board and not having the apple chip (or duplicate), I’m going to try simply removing a working board from a headset and adapting it for my uses!
Again, I’ll let you know when and if I get it working.
I already ruined two headset wires trying this, hahaha. Just be careful when taking them apart and let me know if you find one that is easy to work with.
good way to list all that stuff. @cuckoo should go back in time and concentrate on few machines and the overall questioning from the people–like how does someone at TEs Headquarter Sample in all possible ways with the Z.
I don’t get the general scope on the manually enabling Headphone mode.
it doesn’t work with a TRRS splitter cable but it should, right?
I’ve tested 2 regular TRRS splitters, an iRig 2, and a Bose headset that has the special button. None of them worked. As far as I can tell, I’ve seen no evidence that the headset feature works for anyone. Nobody on any forums, no youtube videos, nothing.
If someone has an Apple headset, can you try using it before you take it apart so we can confirm that this feature isn’t entirely broken or missing?
but there are atleast 2 common wiring schemes for these TRRS splitters.
so just b/c u have a TRRS doesn’t necessarily mean u have one that is wired the correct way
I have just tested it with a headset. Pushing the button activates the orange light on the left and the mic becomes active. So it seems to work.
Tried a TRRS cable also. I could faintly hear the input but could not manage to sample it. The USB I/O is great though!
EDIT: I plugged the output of an audio source half into the input jack of the TRRS cable using a mono 3.5 mm cable and the sound quality actually is quite ok! However, I could not sample the signal.
I ordered the headset buddy and just tested it, no luck. I think I’ll wait and see a youtube video of someone sampling with a cable before buying anything else.
don‘t know why. maybe they‘re coming with a new module with inputs/outputs or the actual Oplab Module can be used to switch from CV or Gate to Audio Signals and use this as Monitor and Mixer etc.
I really don’t understand, why EVERYONE is saying line-in-sampling does not work.
Because it does!
I’m using this exact splitter:
And it works like a charm, without any problems. I sampled my bastl kastle with it.
What might be important:
I use a stereo-cable to connect the kastle to the splitter’s mic-input. I think I first tried a mono cable and it did NOT work (not sure about that, because I had a lot going on on my table But might be worth checking…)
Activate headset-mode by pressing “screen” and “shift” BEFORE entering sample mode. You can’t switch to headset-mode, WHILE in sampling mode!
If you hear a dim signal but are not sure if it’s really fed into the OP-Z: BEFORE entering sample mode, pick the OP-Z up, as if you want to use the internal mic. Now try to control volume or try to activate FX1/2 for the mic, as mentioned in the manual. If nothing happens: the signal you hear is NOT fed through the op-z, but directly to the output. I don’t know the wiring, but that might happen. Sampling won’t be possible and you have to check your connections. If you can controll the input sound like in mic-mode: Sampling will also work!
EDIT:
Don’t forget to press “play” for monitoring in sample mode. Although sampling will work without it.
One last thing: Might sound stupid, but be sure the cable is completely plugged into the splitter. Perhaps you have to push it one click further.
