Pitch Raise using RCT

[Dean Reyburn]

Hi David,
Either of the first two methods you mention will work but sequences  
are faster than others (the third one would work but would be really  
slow).

I'd recommend you use the sequence that gives you the most efficient  
muting and tuning pin sequence, which varies from one tuner to  
another. The sequence depends on if you are pulling out strip muting  
or using rubber mutes. In any case there's no need to pull up unisons  
literally left to right for each note if a different sequence is more  
efficient (as long as you generally pull up unisons as you go).

I still like to strip mute the piano and pull out the strip as I go.  
So I let RCT sample the center string on a trichord, then pull out  
the strip to the left of the unison and pull up the left string of  
that unison, then pull up right string of the previous note/trichord.

However in talking to a lot of tuners using RCT, most pitch raise  
with rubber mutes, either two mutes, or a single split mute. The  
method that is best is the one you're most comfortable with and/or  
fastest with. I'm faster and more comfortable with strip mutes for  
some reason, maybe because I tuned strictly aurally for so many years.

BTW, there is a CyberTuner listserv called ctuner at reyburn.com which  
is free for RCT users. To subscribe:
