  • 1.  Zoom presentation offering by Steven Norsworthy to Electronic Tuning Members

    Posted 12-29-2023 01:23

    Hi, Fellow Members of the Electronic Tuning group. I am offering to do a zoom presentation and class on advanced piano signal processing and how the PianoSens solves perhaps the #1 variance in piano tuning: acoustic jitter and interference. If I can get most of you (5 members in this group) to agree on a time this coming weekend, perhaps Sunday afternoon Pacific Time, I will send you a zoom link for the class. Let me know. If this Sunday afternoon is not good, I could also do Saturday afternoon. 

    Happy New Year!

    Steve

    As a lifetime aural tuner of more than 50 years I have always corrected for this intuitively.

    Hi Parker:

    This reference to jitter and interference is inherent in electronic tuning, and of course you don't have that problem doing tuning aurally.  All the tuning apps have difficulty with this, which is why I don't favor eliminating the aural exam for becoming an RPT because you need that skill even if you use an ETD.  Mismatched bichords and false beats are difficult for both aural and electronic tuning, so you do have to have aural skills to make a judgment call.  For years I used the Accutuner, and now I use Pianoscope with Steve's Pianosens, which allows you to avoid the reflections and resonances coming through a microphone.  The Pianosens eliminates the acoustic noise from aliquats, unwanted room resonances and anything that a mic picks up.  It only senses the movement of the string it's on top of. Our ears are also microphones, and have the same defects, though we don't realize it.  We've had these ETD's for many years, and they work very well, but we have also been advised to check every tuning by ear, and every unison also by ear.  But this new sensor enables an ETD to work better and more accurately because it doesn't have to filter out the acoustic noise.

    Hi Paul,

    I've been following discussions on the other threads on PianoSens. Please tell us how long your tuning time is when using the sensor (grand, and smaller verticals). 
    Have you successfully used PianoSens with the latest version of iRCT? Are improvements significant?
    Many thanks,

    Pat Draine

    Obviously, depends upon how close it is.  I did a Yamaha U3 in about an hour and fifteen minutes yesterday.  Within 5 cents plus/minus.  With a pitch raise, a Wurlitzer console that hadn't been tuned in 40 years (nearly 100 cents flat in treble) took me a little over 2 hours, pitch raise and tune.  It does take more time string by string, which may or may not be worth it on an upright console or spinet.  On grands, yes, string by string.  The resulting unisons are better than I can do by ear.    Grands are about the same time.  I'm using the Pianosens mostly on grands, but bigger uprights too, not so much with smaller uprights. But I have done it successfully many times with Pianosens even on those smaller PSO's.  Overall it does take more time, but the result is so much better, and I get unsolicited compliments from clients. 

     I don't have Cybertuner, but at a recent conference in Riverside, we had attendees who connected the sensor to their Cybertuner, and it did make the readout steadier.

    Those times are quite reasonable to me (as an iRCT user). That said, I generally find the  iRCT display quite steady. I used the Sanderson devices (SOT, then SAT) up until the past 20 plus years, then RCT, and am quite habituated to a rotating display rather than lines on an X-axis. While the "easy" setting is 1.7 c per rev/sec, one can set it as high as 0.4 c per rev/sec. If I'm fine tuning I usually set it at 1.0 c or even 0.8 cents per revolution/second. 
    so many paths (now) to the goal!
