The tonal design of an organ is the = starting point for the desired finished sound. Correct scales are the first = decisions made. The "charm" is when everything blends to get a "pipe chorus" not unlike working with a choir. The quality shows through when a builder = knows what ranks at what wind pressures, pipe scaling, and voicing techniques = will work for a given acoustical space. When I do low pressure open toe = voicing there is a big difference in the results from my work on high pressure pipework. On the former, you had better know what you are doing or you = end up with a mass of whistles with little musical character. Many current builders of trackers have not mastered the open toe voicing and your ears = can tell the difference. I have yet to find an electric valve organ that = gives the correct speech envelope and most pouch valved organs fail to provide = the concussion chamber for a nice attack of speech. Oddly, of the electropneumatic actions, only Wurlitzer provided for a speech envelope = that mimicked the trackers by having each pipe sit on its own concussion = chamber. Roosevelt actions and the new Schoenstein organ actions also have some = space for the wind to steady out and turbulence diminish before the wind reaches =   the pipe toe.   The organ is a synthesizer. It is the embodiment of Fourier transforms. When everything is done correctly, the waves produced from each pipe blend = in with the other pipes to produce a summation of harmonics and fundamentals. = It only takes one pipe with dissonant harmonics for our superbly sensitive =   ears to send the message to our brain that a sound is not pleasing. Just = one buzzy reed or wheezy flue pipe and the whole blend falls apart. Much of = the eloquence (charm) is in each pipe fitting perfectly into the whole = instrument.   Al Sefl
