<HTML>Ron, They tuned various sections of the same piano,seeing how the etd responded,= and checked to see if they agreed aurally.Don said the person in charge,had = to miss the meeting at the last minute,so it was not as organized as it coul= d have been.I hope to soon do the same kind of testing as you state,at a cha= pter meeting.I also think the majority favor for the pocket rct,was not only= how it responded,but also size,sensitivity,and features.
