This is written for no other reason than I like to talk and I like to use words. For listing to me blabber I have conjured up a contest. There is a prize for the winner also. I thought the prize might be considered invaluable. When I asked Ruthie for her opinion she said ‘What’s That?’ A rendition by You? Well, I told her, it will give me something to do. Besides, not everybody walks out of the room when I interpret things. Just because you do..... Come on, be nice. So hears' my mouth via my fingers.
Quote: “Touch sensitivity is NOT A REPLACEMENT for a properly used expression pedal”. So very true. True, true and true. Question: When is an expression pedal (swell pedal) proper? Answer: When used on an organ or a keyboard set up so as to be played as an organ. Up until recently organs had no touch sensitivity and limited after touch control, mostly on pipe organs. On the keyboards of today some of the organ voices still do not respond to key sensitivity. Therefore this pedal was mandatory on organs and is provided as an extra for those few who purchase a keyboard and want to set up and play it as an organ. No other way to increase or decrease the volume while playing on the thing set up as an organ. Now that the question of when an expression or swell pedal is proper let us delve into how an expression pedal is ‘properly used’. An expression or swell pedal is used to give a STERILE (no expression) organ sound, expression. You might say to swell up or down (swell pedal) in greater or lesser amounts of volume. Kind of like our bodies. We get a swelling and then we say the swelling is going down. A properly used expression pedal therefore is used to give an otherwise constant tone, life, excitement or the term ‘expression’. A properly used expression pedal brings up the suggestion of an improperly used pedal. How can an expression pedal be improperly used? A proper expression pedal use on either an organ or a keyboard programed that way can be improperly used as a foot rest and or to keep time, a favorite of many organ enthusiasts. Occasionally used to give accent to a sneeze or cough or among other things such as an itch or twitch in ones leg. Silence or a burst of volume when triggering a side switch on the pedal of an organ is another favorite trick of misuse on organs.
As for keyboards. If an expression pedal was essential for the performance of an arranger keyboard it would certainly be included as standard equipment by the manufacture. The fact that the expression pedal is able to be purchased as an extra is an indication it is an item to be used for a particular situation, not the normal use of the keyboard. The design of our keyboards is such that the method designed into it for full and complete expression of the same, is a completely different approach for expression, more refined and sensitive to that end than the organ approach. Therefore when an expression pedal is proper for the situation is when used on an organ or a keyboard set up and used as an organ. When an expression pedal is ‘properly used’ it is used for degrees of volume. When not properly used, is as stated above, for keeping time etc.. Larry, a great similitude, and Mike you are so right. As long as they are offered to keyboard players there will always be confusion. Confusion when there is reluctance to overcome an ingrained habit when using completely different technology. As an example: I can play my saxophone two different ways. I will take my sax or clarinet out of the case, slap on the mouthpiece and blow it. Blow harder and it is louder. Turn on my keyboard and play the sax. Hit the key lighter or harder and that is how I control loudness. When using my real sax I apply more and less pressure to the reed which causes the pitch of the note to be flat or sharp, which gives me vibrato. On my keyboard this is done electronically. Either programed in with the sound or triggered with after touch. The pitch of the note is varied by making it flat and sharp. Therefore complete control as on the real thing. Not so when using the expression pedal. The best that can be done to achieve vibrato is to wiggle the pedal back and forth to vary the volume. Very hard to simulate. Besides, true vibrato is varying the pitch, not the volume. The ability of an arraigner keyboard to reproduce these effects is the whole purpose and design of the product. The use of a leslie tone cabinet on a hammond organ is a mechanical example to accomplish this. I wonder how many know how and why the leslie will give this effect. Anybody that can come up with the physics of this, I might, if I have the time, energy or the music, to send you my rendition of ‘How Great Thou Art’ done on either the 6 or 7 thousand. I have both. Come to think about it, I will need the music, so send it with your entry if you think you got the right answer. Just send it to Dougies Dumb Contest, C/O SnythZone BBS Technics Discussion Forum in the Expression Pedal Slot. Otherwise just hit the reply button at the bottom of this page. Same thing. Ruthie says by the time I get done explaining something to her it’s time to go to bed. If you find me a bit too wordy I would like to say goodnight now.
Grandpa Doug, author and administrator of Dougies Dumb Contest. Ruthie will be the official judge so you all got a chance.

How I have used the expression pedal. 1-No rhythm--As you listen to an orchestra playing waltz, semi classical selection, or a solo instrument---they do not play at a constant volume. The changes in volume do go beyound that of the touch sensitivity of the keys on the keyboard. Sometimes down to a whisper, returning moments latter. 2-I use it for my solo part, Rt1, Rt2. When the pedal is at ful volume, I am playing a solo. When I am singing, that same sound is lowered, putting it in the backround. No buttons to press. Nice. 3-I also use it for my left hand sounds. It's nice to hear a backround sound vari, it adds alot.
On that note I will say, I never take the pedal to a job, it is another thing to worry about. There is enough going on without adding more stuff. The one time I did use it, I couldn't remember if I was full volume or half, or whatever. It is a good feature, I imagine with a lot of patients it would bring a player to another level of playinmg. In my humble opinion, John C.

While Grandpa is right that Touch Sensitivity can be used to 'swell" a sound with your right hand, it does nothing to increase the volume of the rhythm with your left hand. Unless one plays like FonzyBear of the Muppets...You know, like a mechanical pounding up and down with the right and lefy hand, kinda like the characters in 'It's a Small World' at Disney .(annoying after a while)
If you notice, when you press the intro and ending button, sound and rhythm swell up and down together, in a flowing, appeasing manor. I don't believe you can achieve this whole effect using only Touch Sensitivity with your right hand, unless I'm missing something. I like to be able to increase the rhythm volume along with the sound volume. I think this is where the expression pedal does it's job.
When you play your sax, you only have to play the sound, and adjusting the volume is controlled by the amount of air you supply. (Ruthie say Doug has a lot of air). There is no rhythm volumn to worry about, thus no expression pedal on a sax.
Therfore, it is my belief that the expression pedal can be used in conjuction with touch sensitivity, and a viable option to have . At the very least, it's there if you want it, even if it's used only as an old security blanket. After so many years with a swell pedal, it's tough to do away with a friend who was always there by your side, lying there, on the floor, waiting to be acknowleged.
Grandpa..what was the contest question again ? _____________ Larry Hawk

Question: How does Grandpa manage these sounds - with no expression at all? Answer : When in Rome do as the Romans do.
Can’t believe it! Mike I quoted you and gave my opinion of your statement as follows: Quote: “Touch sensitivity is NOT A REPLACEMENT for a properly used expression pedal”. So very true. True, true and true. Question: When is an expression pedal (swell pedal) proper? Answer: When used on an organ or a keyboard set up so as to be played as an organ. This is how grandpa manages these sounds; When I use those organ voices that do not have touch sensitivity I play the board as an organ, with expression pedal. I never said I played them in any other way. I very emphatically agreed with you. How does Grandpa manage these sounds - with no expression at all? Thanks Mike. What a pity if this is so as these instruments rely on expression pedal operation. I’ll take all the pity I can get. With the advent of the seven thousand we now have one dedicated organ button on the rhythm side and two instead of one dedicated to non touch sensitive organ voices on the sound group side. A small, by comparison, but welcome addition. A very welcome addition indeed for organ enthusiast. This is one reason that you see a room with a big dust covered organ with a shinny new keyboard at it’s side. Mutt and Jeff! I have a number friends in this area with this situation. The keyboard get much more attention than the organ.
I did however point out orchestral instruments are handled in a different manner on our keyboards. The method used to make them sound realistic is different than for organ sounds that have no touch sensitivity on them. I thought I was saying control of orchestral sounds is better controlled and more realistic with touch sensitivity and after touch rather than the expression pedal approach. This is my opinion and I will stick with it. On the other hand I know of those who set the touch control to zero and use their old trusty expression for all instruments. Each to his own. I suppose mentioning there is another button with many organ sounds that are touch sensitive and can utilize after touch will disappoint some. These are the organ voices I use when playing orchestral style music and not in the true organ environment of the board. Variety is the spice of life they say. ‘How does Grandpa manage these sounds - with no expression at all? Very well thank you. Familiarize yourself with and understand what you have spent all your money on and you too can experience more spice in your life. Larry, a security blanket will do nothing more than cover up real security. As for your friend, let him have his freedom to do what he does best. Don’t force him to work with band instruments when his love is for the organ.
Could be wrong, Larry, but I don’t recall discussing rhythm volume. However I think that would be a very interesting subject. I see you do this with your expression pedal. I understand the concept and certainly will explore your approach. To date I have a number of ways to accomplish this end but always looking for other approaches. Fonzy Bear? Pounding up and down? Annoying after a while? You bet, and boring to boot. When you play how do you set your expression pedal. To full expression or part expression and why? Which works best for you? My guess would be full expression. Would like to add this to my style of playing. Never can have too many ways to skin a cat. By the way, Ruthie qualifies the air. Not just air but hot air. She also uses a qualifier for air of the other end. Would any of you other guys like to chime in on the subject of how you vary or lend expression to the rhythm part of your playing, not air?
OK Larry and Alec, I can’t even spell a lot of the words you guys are using much less know what they mean. Good thing I gave the judging part to Ruthie. I told her to look this over. After a bit she said she was going into the kitchen to start making supper. Up till now these are the only words she has spoken. So far nobody sent me the music. Hay fellows, I’m just an armature and am just going around in circles until I have a chart in front of me. However I do know Jingle Bells by heart and will substitute that. OK? I will have to E-Mail it but if somebody would like to post Jingle Bells everybody could see what a fool I have made of myself.
