Does anyone know where I can get a good collection of renaissance instrument samples or more specifically a sackbut?  BTW. I'm not trying to be esoteric these have a very unique sound.  Maybe a cross between the sound of a bagpipe and the bleat of a goat.

I found that there is a collection called *era II* that's older and runs on the Best service 2.0 engine (not kontakt).  Sounds kind of iffy.  Does anyone have any experience with this particular collection?  I've bought some of these older loops and they can be a little goofy.

You could see if these guys still exist, they give an email address

For some baroque instruments mostly strings, drums and such

Thanks biggcat I did find a crumhorn at spitfire which is adequate for some stuff just to sound period...

Check out Bolder Sounds Early Instruments Collection. I don't think there is a Sackbut but there is a wealth of other period instruments.

I have Era II, and its great (and its not that old -- just released last April). Samples are very nice, and the programming is good. Some of the instruments can be tricky to play, but I find the library really useful.
 
Best Service's Engine 2 is fine. I've had no issues with it.
 
 
 
 
 

My butt was sacked once and only once. I deserved it too.

At last someone jests about this funnily named instrument. Juan kan olwayz kount on Bapuji.

Oh thank you for the favorable brief, amicable.  I shouldn't have pre-judged the best service collection.  Era 2 may be a must buy for me.

I was going to say something but figured it would be undignified. 

Yet you are worthy, Father of Bass.
