Plug-in to write drums that will work with Kontakt libraries

[Grant Ransom]

"I want a sequencer to write for the samples I already have."

There's your answer.

You need to sequence MIDI notes to trigger the samples.
How come you bought the NI software without having a DAW or sequencer?

I have Pro Tools with a MIDI sequencer, yes.

But I don't want to write drum samples with a stupid pencil tool...

I'm asking if there's any plug-ins that can sequence the AR-kit. Like with matrix cells, or other things. Like Battery. Something that is great for composing midi sequences, but doesn't come with gigs of samples I'll never use.

I sort of assumed AR would come with a way to sequence the drums.

There might be - not sure.
Thing is, the "live" kits will benefit from sequencing that isn't grid-locked.

The piano roll style editors are much more flexible than a grid sequencer. IMO they are worth learning to use. Also one can play-in from a keyboard.

In other words you'll need a controller wich send midi data in to your daw, so that this data can be played back by your NI kits, or any other kits, in your Daw.

Such controlers are midi keyboards, or just midi electronic drums etc.

Then some daws, like Cubase/Logic etc, have "specialised" Drums editors, when you can "program" your drum sequences by clicking spaces on matrix lines, each line representing a dedicated drum module ( BD, Snare, etc ) .

The last solution is to rely on some companies who sell premade midi drum patters in various styles, sometimes played by skilled drummers. You can always further edit these patterns in whatever midi editor of your daw and modify them to your taste.
