Finally! A device that makes hearing beats easier, and in REAL-TIME!
Use the PTE-101 to:
- Hear what master piano technicians hear,
- Be able to tune unisons and intervals accurately,
- Train your ear to eventually not need the PTE-101
That's right! The PTE-101 is the first Electronic Tuning Device (ETD) that trains you how to NOT use it eventually.
All current ETDs make you a slave to its functions. Once you start using a traditional ETD, you stop using your ears and when you stop using a muscle, it atrophies. How can you get better at aural tuning when you don't use your ears. The answer is: you can't!
With the PTE-101, it helps you hear the beating of each interval. It also has a dial that can reduce its effect, thereby challenging your ear to focus more.
Not ready to hear those beats inside the interval yet? No problem. Just keep the bandwidth turn up to high until you are ready.
Meanwhile, listen to all the piano intervals and easily pick out the clean and pure beat of each interval.
By using this device you can stop worrying about not being able to hear beats and finally get to trying to understand the theory of aural piano tuning and actually using it!
Without a device like this, many people give up on learning to tune pianos aurally and aural tuning is still the Cadillac of tuning methods; routinely beating all ETDs in the results produced by a trained ear.
That's why I invented it. I was dejected by the number of people giving up on aural tuning. I knew I could help them get professional results but I couldn't fast track their ear development...until now.
With this device you may not even want to turn it off. In fact, you wouldn't have to, it works that well.
Watch the video below and when you're ready, click the link to purchase.
But I warn you, this device is not pretty and it's not cheap.
It took me 10 years and thousands of dollars to get a working model. I sent all my parts to different electronics companies and technicians. The Chinese, the Americans, independent electronics technicians, nobody could make a simple circuit that could do this. I knew it worked. I made videos years ago showing it working with off-the-shelf components.
Finally I couldn't take it anymore. I had already refunded a customer their money for the pre-order plus 10% because I was so ashamed that the device wasn't ready yet.
So, I took matters into my own hands. I'm not an electronics technician, but after many attempts and trying different components, I got a working device.
It's not pretty but it works. It allows me to hear any coincident partial as clear as day and you can turn it off when you feel your ear is strong.
I can't wait to hear how this device is changing people's lives, finally helping them to hear these illusive beats that have been taunting them since they started tuning. Piano technicians know the pain of developing their ears to hear beats clearly and we all wish we had something like this when we were starting out.
So, watch this amazing video and see how easy it is to finally hear beats. And then click the BUY link. The price reflects the fact that these are all on pre-order and therefore will take a while for me to make, but when you finally get it, it will be well worth the wait!
