Demos sound reasonably authentic!
 

Ilya Efimov Production has released a new sample library for Kontakt – The Uilleann Pipes – adding another instrument to the Irish ethnic series.
The Uilleann Pipes are the national bagpipe instrument of Ireland. It’s unusual and complex one in its construction, requiring from a player quite a bit of mastership. With this library - a complicated instrument like the Uilleann Pipes – now becomes easy available to anybody!
 
In our library we sampled two full octaves for the chanter – main instrument’s reed, - including fast and slow legato notes, as well as other articulation like vibrato, staccato and mordents. There is also a special range on keyboard for playing regulators and regulators’ chords to accompany chanter’s melody with simple harmonic backing. Plus we designed the suitable ways to turn on/off the drones, bellows noise and other bagpipe FXs, which helps to provide the realistic sound of the library.
 
FEATURES: • 576 Mb ncw compressed format • 750 samples, 44,1 Hz/24 bit, stereo • 2 natural legato types: normal and glissando • 3 modes of legato performance • 8 different articulations • Two vibrato types • Control of realistic vibrato – its amount and speed • 6 round-robin realistic staccato • Reassignable keyswitches and midi-controllers • Drones start, tune and volume control • Chromatic scale for regulator keys Regular price: €59.00

Does not look like there is an intro offer.

Definite rumblings of GAS here about this one, so I have just fired up East West RA which has Uilleann pipes, they are pretty good but don’t look as detailed as the Ilya Eftomov ones.  Half an hour of noodling in Mixolydian and Dorian modes with the EW pipes has made Smeagol say I have this sound covered well enough and Gollum say no we wants it  precious…

Glyn . . . . put the Hobbit DVD down . . . now, back away . .  slowly . . . . s l o w l y . . .
 
I for one like the Ilya stuff a lot, it generally runs "rings" around the competition. I'll give those Uilleann pipes a spin, thanks for the heads up.
