I've been watching tutorials on setting up Reaper's built in sampler 'ReaSamplomatic5000' as a drum machine, but it just seems like it won't do what I want. I also miss the way that you could browse your drum library with FLS's interface and automatically preview each drum sample just by highlighting it with the arrow keys instead of having to load it into the sampler to check it - that saved a lot of time! I like being able to have all drums triggered by one midi clip, but also having the ability to do some drums on one midi clip and some on others (I often separate Kick & Snare into one clip, Hats on another, then random ones for cymbals & Toms).
I'd really like something similar where I can start by using the step sequencer to make a basic beat, then edit the steps/notes further by going into the piano roll and changing things like the pitch & velocity of each hit. I've come from using FL Studio and need help getting a good drum machine setup like FL's sampler/sequencer & midi clips.
