For the musicians here on WC that record using a DAW, now is the time to get a deal on some plugins at Plugin Boutique. http://www.pluginboutique.com/
There are many on sale, but 4 of them caught my attention due to the combination of price and sound quality.
My favourite is DB-33, a Hammond organ/Leslie combination, because I have the real thing (a BC from 1938, and a 251 Leslie), and I love the sound of a Hammond. This emulation captures all the small details of a real Hammond, such as key click, dirty tonewheels and so on. There are two programs; the Hammond (with a Leslie), and a separate Leslie program. The price of this one is US $23.99; the sale on it ends Jan. 5th. http://www.pluginboutique.com/product/64-Virtual-Instrument/1684-DB-33
Orchestral Companion Strings is another. I haven't tried it out a lot, but the sounds are very lush, it has a lot of articulations, the Midi Learn is extensive, and the library was sampled at many velocities. There are about 8GB of sounds. The best thing is the price: US $1.00. One unfortunate thing about it is that there isn't a manual for it. The sale ends Jan. 31st. http://www.pluginboutique.com/product/1-Instruments/64-Virtual-Instrument/1845-Orchestral-Companion-Strings/?gclid=CLOf_YDMnNECFVK5wAodgh4Jng#a_aid=57ef7faf6caa0
Next is Big Bang Universal Drums. Once again, I haven't tried this one out too much, but I can say that the sounds are very clean and well recorded, and don't sound as "tiny" as a lot of drum samples that I have heard. Midi Learn is good, it comes with effects, and there are about 8GB of sounds. The price is US $16.00. I don't know when this sale ends. http://www.pluginboutique.com/products/1848-Big-Bang-Universal-Drums
Last is Xpand!2, a synthesizer workstation. I haven't had time to try this one out too much, but it has good reviews and what I heard sounded good. The price is right at US $1.00. The sale ends Jan. 31st. http://www.pluginboutique.com/product/1-Instruments/64-Virtual-Instrument/1560-Xpand-2
