Yes and I'll agree the brushes in TTS-1 for certain songs are good. So what I do is use both.
Example:
Kick -TTS-1
Snare- TTS-1
All the other drums Session Drummer or ?
Simple matter of having your drum parts in there own tracks.
The trick of transferring TTS_1 sounds into a sample to be used by other drum synths is not that hard once you know where the files are stored for the samples.
Make a midi track, point at TTS-1 set to recording
Slowly play each note on your Keyboard that has a drum sound.
Now freeze the track to create an audio track.
I open this in a wave editor but you can do it in Sonar too.
Now just cut and paste each sound to it's own wave file, cut to the very start of each note and leave the decay as short as possible. Save each part and name.
Now drop these into the Session drummer folder where the sounds are stored.
This brings up a question --- Can you play your own samples with Addictive Drums?
