To be playing a tune I know with the new full set I have to pump the bellows at at least twice the speed as I had been with the practice set. Does that sound reasonable? If so its going to take a while for me to get used to it.
Congrats on getting the set!
If you are playing with all the drones, you’ve gone from one reed to four so, yes, it will take more air. It’s likely though that you are wasting a lot of effort at this point. It takes a while to get a feel for the rhythm of playing with drones. It’s probably a good idea to plug the bass and baritone drones and play with just the tenor for awhile. When you are feeling totally relaxed with that, add the baritone, and finally the bass. For me, getting back after my little 25 year break, it was a process of three or four months before I was playing happily with all three drones going, but then I’m an old guy.
Good advice… Thanks
Drones could be sucking too much air. Stop the chanter, turn on the drone, and then touch each to turn them off. Keep squeezing the bag to see just how airtight they are. If your drone reeds are not airtight, or close to it… that could be a source of your problems. With my FS (concert), the drone reeds are very efficient, so I’m not huffing and puffing with the bellows. If your chanter reed is not v. efficient and then you add the same kind of drones reeds to the equation, you’ll be doing a workout! It shouldn’t feel like that.
If you’re new to a full set, and the set is new, and the maker lives in your area and played them for you before you took them home to show that they’re working okay, you’ll likely just have to get use to the new demand for greater air. I wouldn’t start messing with the reeds…or even suspect them being set up wrong. Temp and humidity is gonna be the same, one side of the river or the other. I’d play the chanter with all 3 drones going, get use to that for the first year or so, other than just experimenting with reg possibilities, then after you get use to the air supply needed, have Brad take off the bass and bari regs, and plug the holes, so you can get use to getting around on the nearest reg. It’ll have five keys. Learn what you have to do with your right leg to play the chanter and the lowest key on the tenor reg. There’s a whole lot of intervals possible, they can add a lot to a tune, and if you don’t want to be accidently hitting the reg keys for any reason, just give the tenor reg a 1/4 twist forward and get the keys outta the way. You can add the other regs back anytime…no loss, but an easy gain in the learning curve. 
hi,the step from playing a practice set to a full is a big one but it sounds like you are having unecessary problems.first address your blowing technique.the pipes are controlled by the left elbow on the bag.this is your main concern.the bellows must not govern the playing pressure,they are only used to fill the bag,your blowing technique is paramount to controlling a full set.if you are stabbing at your bellows and your left arm is lifting off the bag and you have an uneven,see-saw motion you need to re-think your blowing.hold your bag as high as you can and blow in the middle of the bag.this gives you maximum air pressure and also releases the muscles on your left forearm to play freely.stance is also important.do not slouch,keep your back straight,shoulders back,keep your bag high and put your left leg out and your right leg back and let the set lay over your right thigh.at this stage do not even think about playing the regulators.i can not impress upon you too much the absolute importance of blowing properly!!!i reiterate.your left arm is your control,the bellows only top up,they never govern your pressure,tone or octaving.tone and octaving come from your left elbow and the mercy of having a staunch set and good reeds.no one set of pipes sounds the same in the hands of two different pipers.you must also consider the air worthyness of your set.take your chanter out of the bag,put your finger on the chanter stock and fully inflate the pipes pressing hard on the bag,if the bag deflates significantly over a period of about two seconds then you have leaks,the pipers curse.the range of leaks is legion and i can not deal with them and their remedies in this short mail.next come your reeds,the most important consideration of all.i think i will stop here or i will end up writing a book.basically when a full set is staunch and reeded properly and blown properly it requires little more air than a practice set,some more yes but not a huge amount.the equasion that 6 more reeds take that much more air than the chanter reed is erroneous if the set is well set up.anyway mate i am off to bed,wish i could do more.i remember 30 years ago when i first played a full set what the problems are.blowing technique,air tightness and good reeds are the way to go.good luck.allan moller.
