Groover v1.2

Groover is an open source script for humanizing midi drums in the Reaper Midi editor.

How to use:

Stand-alone:

• Download groover.exe, groover.lua, preset.json, settings.json and help.md from dist directory.

Source code:

• Download groover.py, groover.lua, preset.json, settings.json and help.md from root directory. (requires Python to be installed)

Use:

• Change the desired settings directly in the code or use Python gui (groover.py or groover.exe) outside of Reaper to make changes.
• Select the notes you want in the midi editor and run the goover.lua script in Reaper.

Settings:

(in the groover.lua file change the value of the ("local timingVariation") variable for example or use the gui )

• maxVelocity: Drummer's maximum volume. (0-127)
• minVelocity: Drummer's minimum volume. (0-127)
• velocityVariation: How much is the intensity of the drum hit change, if 10 then 20 in total.
• timingVariation: 20 = +- 20ms, So a total is 40ms.
• swingAmount: Amount of swing. (0 = no swing, 1 = full swing)
• useHandednessFeature: Use of handedness. (true = on use, false = not in use).
• handedness: Are you right- or left-handed? (right/left)
• handSrenght: Strength Difference Between Hands.

Tips:

• Use a Drumkit preset for the entire drum track.

• Handedness is great for fills to simulating the drum hit, but it can also be used in double bass drum parts to simulate different feet.

• The handedness is also useful with the hi-hat and ride cymbal to make it groovy and human by adding accents in the right places. For example, right-handedness to the 8th beat and left-handedness to the 4th beat.

• The presets are made to speed up the editing process.

• In presets "Tom" setting is made for fills, preset works well in snare fills also.
