Easily convert DRUMS to MIDI in REAPER

How to Convert Audio to MIDI in Reaper

Introduction to the Process

• The video introduces a method for converting live drum audio into MIDI using Reaper, focusing on triggering kick and snare sounds.

Methods of Conversion

• Two methods are presented:

• Native Method: No additional installations required; a traditional approach used by the presenter.

• Script Method: Utilizes a preferred script that speeds up the conversion process.

Setting Up the Snare Trigger

• To convert audio to MIDI, duplicate the track and remove effects. Rename it as "snare trigger" for clarity.

• Add the JS Audio to MIDI Drum Trigger plugin, which converts transients into MIDI notes. Adjust open and close thresholds for optimal triggering.

Using Samplomatic for Reinforcement

• Incorporate Real Samplomatic by adding desired samples to reinforce or replace the snare sound. Set mode to "Sample ignore MIDI note" for effective playback.

• Adjust volume settings based on dynamic requirements; since it's a one-shot sample, keep velocity settings minimal.

Fine-Tuning Threshold Settings

• Use transient detection from the actions menu to visualize threshold adjustments, ensuring only snare peaks are captured.

• Apply track take effects as new take MIDI output for further editing of performance data.

Editing and Aligning MIDI Notes

• Open inline editor (press 'E') to modify individual hits; delete unnecessary one-shots or adjust timing discrepancies.

• Check phase alignment with original samples by toggling phase buttons; ensure optimal sound quality through comparison.

Finalizing Snare Trigger Volume

• Blend in snare trigger volume until it complements the original sound effectively. Loop playback helps assess balance between triggered and natural sounds.

Using MK Slicer Script for Kick Drum

Introduction to MK Slicer

• Introduces MK Slicer as an efficient script available via Repack, simplifying kick drum processing without needing new tracks.

Processing with MK Slicer

• Load MK Slicer script directly onto existing tracks; it processes audio quickly while providing immediate results.

Features of MK Slicer

• Describes how MK Slicer functions like a player with its own timeline, allowing users to loop specific sections easily while syncing with Reaper's timeline.

Kick Drum Processing Techniques

Understanding Waveforms and Filtering

• The Red Waveform represents the filtered signal, while the Blue Waveform shows the original signal. High cuts can obscure peaks in the waveform, making it essential to choose appropriate filtering settings for kick drums.

Setting Thresholds and Markers

• Adjusting the threshold allows you to capture peaks effectively. You can right-click to place markers if something seems missing, facilitating a more detailed review of your audio track. This feature enhances workflow efficiency when editing.

Triggering MIDI for Kick Drums

• After processing, set up a trigger for your kick drum using MIDI notes; C2 is commonly used. The dots at the top indicate velocity ranges that help determine hit intensity based on peak or RMS levels. It's advisable to leave this setting on peak for accuracy.

Aligning Kicks and Ensuring Phase Coherence

• Once MIDI is generated, name it (e.g., "kick trigger") and color-code it for organization. If any kicks are slightly misaligned, adjust their timing accordingly to ensure phase alignment across tracks—this step is crucial for achieving a cohesive sound in your mix.

Blending with Other Tracks

• When blending kick drums with other tracks, it's important to check how they interact sonically; adjustments may be necessary if certain elements sound off or clash within the mix. Removing unnecessary one-shots can also improve clarity in big hits during playback sessions.
