Procyon AudioStrobe Adustment for NeuroProgrammer2 & Mind Workstation

To NP2 and MWS users,

The new OS has greatly enhanced the AudioStrobe experience in both NeuroProgrammer2 and Mind Workstation.

The attached procedure was developed to help find the optimal AS analog settings for your computer. The procedure functions equally well on the TI (Rev 1) and SiLab (Rev 2) version Procyons.

I would like to thank CraigT in New Zealand for his assistance.

Enjoy. :glasses9:

Hey Jturner,

Thank you for sharing that bit of information. It's very helpful for me, as I am still considering all my options before I make a purchase of a mind machine (either Proteus or Procyon).

Would you think, with the newest frimware update, that the Procyon is now on par with other leading mind machines audioscrobe compatability?

As I've already mentioned, I am still considering all my options, so any information would be greatly appreciated.

Thank you

Without any question, the answer is yes.

Well that settles that then. Cheers :cheers:

Hello,

Would you please explain what is meant by 'Mute ?Windows Sounds?, in Step 2 of the document. I use XP.

Using USB Power adapter to AC power supply or laptop USB port is not working well inspite of using 2 snap choke core 273-0067 on the USB cable connecting the Procyon. What is the difference in using 273-0067 vs 273-0069 as suggested in the document?

I connected 270-0054 ground loop isolator. In spite of best effort, I am not able to use NP2 on the HP laptop. First I adjusted the Brightness. When I set the min threshold on the AS Volume, whatever I set for NGT (went upto 10) the red LED seems to blink once-in-a-while.

Any suggestions?

Regards

Srikrishna

I turn off all the Windows alerts and other sounds via Control Panel/Sounds and Audio Devices/Sounds, Sound Schemes: No Sounds.

Sorry I can't help with the other matters as I have no significant problems with the Procyon on any of my laptops - Acer, Asus and IBM.

Basically I connect the Procyon, running off either batteries or an external adaptor, both dials on the Procyon almost full, laptop volume almost full, then use the NP2 setup as per the Transparent instructions. I then adjust the Procyon brightness as required using whichever control brings the most pleasing results for the session I'm running.

I usually use the Procyon in Analog AS Mode. Digital AS Mode seems to need the laptop volume higher than the Analog Mode.

Hope this helps,
Craig

Sorry to hear you are having difficulty using your HP laptop with NP2. First, do not use your laptop as a power source for the Procyon. Use a separate AC USB power adapter. They are available on Ebay for around $5 or locally.

If you think about it, connecting the laptop USB port to the Procyon and the Procyon auxiliary input to the laptop audio output creates a wonderful electrical loop. This can happen when we are using Procyon Editor and NP2. Use only one half the connection at any one time. Procyon Editor - USB to Procyon. NP2 - Laptop Audio to Procyon Aux input.

I found the ground loop isolator "clamped down" on the signal passing from the computer audio output to the Procyon aux input. [Please forgive the terminology as I am not savvy in electronics.] If you are not creating the electrical loop mentioned above, in most instances, the snap choke should be sufficient on the patch cord between laptop audio output and Procyon aux input.

The first suggestion is to use the NP2 AudioStrobe Configuration tool if you have not done so already. Second, once you have selected a NP2 session, you can control the session volume with the "System Volume Control" button. If you have stray LED blinking, try lowering the system volume a "notch" or increasing the NGT by 1 or 2 units. My guess is you have the Laptop volume set too high. A NGT level of 10 is a bit high. However, if the NGT needs to be high for a pleasing audio listening level, so be it. Everyone's situation is different.

I hope this helps in solving your problem. If not, repost.

Is there any way we can get this for Neuroprogrammer 3? I was having trouble calibrating it. I wasn't getting a response from the program sensing my procyon.

I thought the procedure was the same. What exact problem are you experiencing?

Hi Wandering Mind,

NP3 doesn't sense the Procyon - it simply passes through the NP3 audio which contains AudioStrobe. The NP3 Audiostrobe Configuration Wizard should guide you full through the process. Make sure your PC volume is set high and that NP3 otherwise sounds okay through the Procyon.

Cheers,
Craig

Let me go more deep. I am still having trouble.

So I have my procyon connected to a USB port. My LED glasses are in the procyon, and there is a cable in the aux port going from it to my speaker jack. I turn on the procyon to AS, and click to analog mode. Now I am seeing some incremental flashes from the machine. When I go through the wizard in NP3, I begin hearing the feedback noise. When I begin adjusting the volume and brightness settings, I am getting no response from the goggles. They go through the same pattern regardless of setting.

What am I doing wrong? Do I have the wrong cable connected to the aux port? It is a two sided phone connector.
Are the glasses in the wrong location? They are in the procyon like normal. The headphones go in my pc right?

Granted, this is all being done on a laptop, but it's an i7.


Another question if you all would be willing to answer:

I have an audiostrobe CD (Deep Trance Identification), but my CD/DVD drive is disabled for this laptop as it is being used by another hard drive. If I were to rip the files from the audistrobe CD, and find a way to import them into NP3, would they still work with the procyon? What is my best way of going about using the CD?

Disconnect the USB cable and run the Procyon using batteries or a USB power supply to make sure you don't create a ground loop.

Speaker jack on the computer, correct?

---

Feedback noise? What feedback noise? I think the wizard does not create any sound that you can hear, just AS signals.
How can you be hearing anything with the audio patch cable connected into the AUX connector on the Procyon? Are you talking about hearing a sound from your headphones? The headphones should be plugged into the Procyon and you should hear nothing coming from them while testing it using the NP3 wizard.

What is "they"? What is the "pattern" you're talking about?

Ripping Audiostrobe CDs to MP3 has been discussed extensively on the forum. Please do a search for Audiostrobe MP3.

It's a subtle tone used for configuring the AS setting. It comes from my computer because the headphones are not in the headphone jack.

The procyon responds normally if I change the headphone and brightness settings, but changing them in NP3 does nothing.I've noticed that putting in the aux cable to the speaker port does cause the LED glasses to respond, but they are not calibrating when I manipulating the settings in NP3. I have the volume up in NP3, and the speaker setting. [/quote]

The LED glasses are flashing in somewhat fast intervals. There are two tests for calibration in NP3:
1 - Changing the volume setting to a point where the glasses turn off completely.
2- Changing maximum brightness. The glasses are supposed to flash in a sine wave pattern where the lights smoothly dim and brighten. Manipulating this setting in NP3 does not change the flashes that are occurring. They blink somewhat rapidly in similar increments and occasionally go off. The glasses work fine with the presets.


Comments are in red. I'm still trying to work through it. NP3 says I may need a USB sound driver.

This sounds like the root of the problem.
The sound from NP3 needs to go to the Procyon. Plug the patch cable from the Procyon to the Headphone jack rather than the speaker jack. Any sound you hear should only be from the headphones connected to the Procyon headphone jack.

You did disconnect the USB cable, correct?

Thank you so much. That was the root of the issue. I insisted on using the speaker.

Now to work on the audiostrobe CD situation. Thank you!

Glad to hear it! :hello2:

Looks like the audiostrobe CD situation worked out as well. I simply ripped the WAV files, and played them with windows media player. I apologize for complicating everything. Being a psychology grad student doesn't help. lol
