I will not mention products other than one in this post but I have to say that Larry' Seyers's Drums out of Tascam, sounds quite convincing. I love to play drums in real time when it comes to the Jazz Genre. The only way to get the juice out of Seyer's collection to accomodate this is to really practice the sounds (kits) that are mapped out on the keyboard. Of course a few tweaks in post production could really marvel the finished drum part.
Thoughts are welcome here..
