4.8 out of 5
A bit outdated

File system is antiquated, clumsy and time consuming. Takes too long to sample notes compared to other tuning apps. Automatic note switching is only for adjacent notes. Very overpriced app for older technology. Indicator blushing occurs over a wide range of pitch, not as precise as other apps. Have to clean up break by ear or use the time consuming AI mode which sometimes doesn’t always do a good job compared to other apps. If you don’t have strong aural tuning skills you’d be better suited with another app that doesn’t require as much clean up of the tuning. Pitch raising is only based on nearby sample notes. It doesn’t take in account what is coming after, only the notes that have come before. Very unreliable.

Indispensable!

I am a professional piano technician with 37 years experience, and started using this app almost 20 years ago-not long after Dean developed it for Macintosh. (Haha, I think I still have the floppy disk somewhere- serial number 73). I lugged my laptop to work for years so I could use RCT. With each new incarnation of the program I eagerly upgraded- with development of the Windows version I moved to a Pocket PC (which by the way I struggled with, being a Mac guy). But RCT on that device was a seamless transition. And when iRCT was announced I was overjoyed! Now my iPad mini running iRCT and FileMaker Go accompany me everywhere there is a piano, and there are a lot of them in my life. I owe much of my success to Reyburn this app. Thank you Dean!

Pitch Perfect Piano Tuning

Great program! Love CyberTuner !!
Pitch Raises in minutes, not hours,
Keep the upgrades comin.

Thanks!

Does what says, very well

The more I use it, the better I and it gets.

CyberTuner app is great!

Excellent app for a professional piano technician. I especially like the library of historical temperaments for tuning harpsichords and clavichords.

I’m a brand new tuner

I can tune pianos incredibly well and I’ve only been doing it for 1 month! I stopped trying to learn by ear because this is so good.

Simply Outstanding!

I learned aural tuning 30 years ago from my dad, who tuned for the Minnesota Orchestra. Later on, we both used digital tuners made by other companies through the years. I had watched other tuners use the RCT and thought it would be good to try it someday. Some time ago a tuner friend let me borrow his iRCT to tune a fortepiano with an historic temperament. WOW! So I finally made the decision to get CyberTuner at the end of 2019. It’s the best move I’ve ever made! The precision & flexibility is just AMAZING. Pitch corrections are dead-on. My clients & I are stunned at how beautiful their pianos sound. They were really quite good before, but this is another level altogether! Thanks Reyburns!

Very intuitive

An excellent program providing a faster and yet accurate experience, for this aurally trained piano technician of 40 years!

The One and Only

I’ve been using this app for many years now professionally. I can’t say enough good things about it and the way it makes my job easier.
Thank you Dean and Nate Reyburn !

The Quintessential Tool

I’m a concert technician of 20 years...4-5 concert venues per week. Tune mostly Steinways for C&A, store and in customers’ homes. I would never have made it to where I am today without this tool.
It is a “must!”

Indispensable.

You can always go back to aural tuning, but CyberTuner is foolproof when it comes to raising and lowering pitch which every tuning greater than +/- 4¢ has. After a pass, it settles back right on 0 for every note. Love it.

Absolutely Fantastic!

This is *the* app for professional technicians. I had used it to do a pitch-raise of over 200 cents, and landed within 10 cents across the whole keyboard. The Smart Tune setting is well worth the pric3.

This thing is priceless!

My only request is to make it easier to move around the tuning files, such as adopting the “Files” interface and making it possible to move them around that way, instead of emailing etc.

I’m happy to pay the $80 per year to ensure that CyberTuner continues to exist and to get regular bug updates.

Thank you!!!

Great program

When I started tuning a few years ago, CyberTuner was great. Now, understanding all the aspects of it, it has been the results astounding. CyberTuner easily! Pays for itself and the quality result is well worth the investment.

The P12 option has allowed me to generate insanely neat results on spinets and pianos commonly thought of as “junk” - a few calculations, and voila! Even “ye olde” sounds great. Not to say, it also has helped tremendously to have sub-bass option when tuning Bosendorfer Imperials.

Professional life saver

I've been a long-time user of RCT, I had my own device (palm pilot) but after it failed I was hoping with fingers crossed that the RCT team would develop RCT for iphone. It's quite an investment so it was after some thought that I bit the bullet and bought CyberTuner . I am so glad I did. The new iRCT seems to work even faster and more sensitively than the original; the graphics are really clear and CyberTuner is intuitive to use. As I mentioned I was already a fan of RCT, and so am really grateful that I can use an electronic tuner that I know and trust on my iphone. One less piece of hardware to carry around, and an amazing tuning device. It's a win-win situation. Many thanks to Dean Reyburn and the RCT team for working so hard on this.
Also, if any of you techs still have the little stand they made for the palm pilots, i just bent the plastic "arms" a bit and am using it with my iphone. Perfect!
