I have been spending the last week delving deeper into the capabilities of Geist and been pleasantly surprised by things I hadn't even touched yet. I remember seeing the "Expanders" briefly when I first purchased Geist, but never really looked into the content. Most of expanders don't generate much interest for me, but the Cinematic Percussion caught my eye. Unfortunately the samples on their site barely nick the surface on what it contains (4900 samples); but I do like that they have preset performance settings to pads/layers and since they are a penny/sample it seems like a no brainer.
 
Has anyone used this Expander that can offer feedback on how the samples contained compared to other cinematic percussion out there?

I just got it over the Xmas sale. Haven't had a chance to dig too deep...but what I've heard I quite like.

I have been hoping to hear a review  of it myself. For gesit owners that dabble in EDM, or even if you just like fusion type stuff a la nine inch nails, the goldbaby sample kits for geist are the godesseses teets! He plays them through tube compressors and records them on reels. 

Are you all discussing add-on stuff or included stuff?

Add-on

there are goldbaby kits in included too. He also offers some freebie kits in geist and other formats.

The EDM comparison actually carries a lot of weight, since some of the freebies included in the factory content (with Geist itself) by GoldBaby are rather complex and well done. In fact, I began to dabble with the "Song" tab within Geist and the sheer power of this VST was revealed looking at his songs (song/patterns/pad layers... and he uses all 8 engines for some of these). I never really used Geist's internal effects until this past week, and some of the effects alone (even with the simple UI they have) are incredibly nice. Just mucking around with the UI I found the "Inverse Reverb" and it competes easily with BREVERB (included with SONAR) but has the distinct advantage that Geist allows for the underlying clip to be modified as well... no muss, no fuss... and "drum replacement" is as simple as swapping out or layering a pad to taste. I also began to dabble with firing MIDI by channel this week, and the versatility of the Geist engine began to "come alive."
 
I do not own any cinematic material that did not come bundled with SONAR, and when researching options, some are very steeply priced for "playing around" and I have never been able to get into the Kontakt UI (it simply does not appeal to me, not that it is "bad"). I happened upon the Cinematic Percussion by chance today and a couple of the songs on their site do have the sounds I would love to use for some material. At least the video made it clear that these samples have already had some programming done within the engine to create a "real feel" dynamic as well as how they were recorded (plus they can be used in any other VST that will import samples).
 
I will probably nab this in the next couple weeks and check it out.
 
Edit for lawajava - I tried to include the link to the add-on page in the OP, but had to remove it... I posted the OP twice and it was immediately deleted with that link embedded, but the "Geist Expanders" is a section on the FXpansion site, so is easy to find. I am not sure why that link qualifies for "automatic deletion" though

I may be mistaken, but i think geist actually has one of the plate settings Sonar does not have

I happened to remember my log in to FXpansion's site, and the expansion packs are 50% off which wasn't obvious just browsing. I bought this pack and most of the samples are pretty decent. I have to delve into it more, but many of the pads have 8 layers that are triggered via velocity. No full presets included, but there are a few dozen engines and kits. The rest are kit pieces.

What's nice about this pack is the layering you can do.  The engine presets are the key.  Put a bongo engine preset into Engine 1.  That gives you mapped bongos and a number of different patterns. Now, put a some other percussion on Engine 2.  Then go to Engine 3 with another type of percussion.
 
Now, you have some complex layered percussion with lots of variation by changing the patterns and having all three engines running.  So, it makes it pretty easy to set up some quick but complex percussion tracks. 
 
The only quirk I can recall is that the filenames are so long (due to being nested so deep in folders) that it made it difficult to install on my old PC.  You had to install it with the installer files in the C: home directory so that you didn't run into problems.
