<html> <body> Hi Ed,              Here's a suggestion that has worked for me.   Aggressively lift the strings.  I think you know what I am getting at.  The sustain will also increase, and give an overall tone improvement. Regards Roger. <blockquote type=cite class=cite cite="">I have to be picky here, the piano is miked and broadcast through a concert size sound system to about a 1000 seat church.  A church that has the music, (Christian Rock), as a central focus!  I am presently getting the job done with flag-poling as a tuning technique, and they tell me it is better than it has ever been, before.  However, maybe all those years in recording studios has made me incapable of accepting ANY drift in the unisons.  I have a hard time accepting that I can't beat this thing into shape.  Regards, Ed Foote RPT <a href="http://www.uk-piano.org/edfoote/index.html" eudora="autourl"> http://www.uk-piano.org/edfoote/index.html</a> <a href="http://www.uk-piano.org/edfoote/well_tempered_piano.html" eudora="autourl"> www.uk-piano.org/edfoote/well_tempered_piano.html</a>   _______________________________________________ Pianotech list info: <a href="https://www.moypiano.com/resources/#archives" eudora="autourl"> https://www.moypiano.com/resources/#archives</a></blockquote> </body> </html>
