# ReaSamplOmatic 5000 You can load up multi-velocity samples pretty easily.[^1] ## Making a drum machine Create an instance of ReaSamplOmatic for each sound and set each instance's "Note start" and "Note end" to a single value.[^2] I start at 36, for [[General MIDI drum mapping|GM-style]] mapping. To create choke groups, insert an instance of JS MIDI Choke before the instances of ReaSamplOmatic. This is useful for closed and open hi hats. Make sure to enable "Obey note-offs" on the open hat.[^1] Using Reaper's routing functions, you can send each instance of ReaSamplOmatic to a new track.[^3] ### RS5K Manager MPL has a script that makes this all much easier. Create a parent track, then from the Actions menu, run RS5K Manager. When you drop a sample onto each drum pad, it creates new track for that sample. When you insert your first sample, it also generate a MIDI bus. ## Round robin Create multiple instances of ReaSamplOmatic for each round robin. Select "Round robin" for each instance. For two round robins, give the first instance a 50% probability of it playing. On the second instance, give it a 100% probability. For three round robins, give the first instance a 33% probability, the second a 50% probability, and the third a 100% probability. For four round robins, give the first 25%, the second 33%, the third 50%, and the last 100%.[^4] [ReSampling With ReaSamploMatic5000 - What is resampling - How to resample in reaper - YouTube](https://www.youtube.com/watch?v=uDWurxVfoJI&t=653s) [^1]: [Multi-Velocity Based Sampling in REAPER (ReaSamplOmatic5000) - YouTube](https://www.youtube.com/watch?v=cpflzlLFms0) [^2]: [Creating a Drum Machine in REAPER (NEW) ReaSamplOmatic5000 - YouTube](https://www.youtube.com/watch?v=CkdksJGg214) [^3]: [Individual Outputs for the Drum Machine in REAPER - YouTube](https://www.youtube.com/watch?v=1kAz3_nB2-k) [^4]: [ReaSamploMatic5000 Multi-velocity layers and Round Robin - YouTube](https://www.youtube.com/watch?v=zjfsUKgOVr4)
