  • Converting Audio to MIDI Chords(0'20 → 3'05)
    Right-click a loop and choose 'convert harmony to new MIDI track' to extract underlying chords as a new MIDI clip from an audio sample.
    • Use highlight scale and scale enabled to spot and delete notes that don't belong to the key (non-purple notes) • Apply 'fit to time range' feature to convert messy MIDI into simple, clean sustained chord progressions • Pull down high notes to adjust the voicing as needed
    • Pitch chords up a few semitone to instantly change the feel • Invert chords to shift all notes upside down • Use reverse to change the order of chords
    The transformed MIDI version sounds significantly different from the original audio sample, creating a refreshed musical foundation.
  • MIDI Transformation Tools: Arpeggiate and Chop(3'05 → 6'06)
    The arpeggiate transformation prints arpeggiated notes directly into the MIDI clip, allowing free editing of the notes unlike the standard arpeggiator MIDI effect.
    • Breaks chords into rhythmic staccato bits • Yellow squares can be deselected to remove notes from the pattern • Blue squares emphasize certain notes • Gaps value controls how many times a chord plays before skipping • Part sets the number of parts for chop notes • Variation introduces randomness to note start times
    These tools are perfect for creating bouncy syncopated piano rhythms characteristic of classic 1990s Chicago house tunes.
    With just a few parameter tweaks, you can transform a basic chord loop into something completely different and unique.
  • Creating Atmospheric Vocal Sweeps(6'06 → 11'11)
    Start with a vocal ad lib and pitch it down two semitones to match the project key, then verify it's in tune within the beat context.
    • Disable the input filter and boost the diffusion network high end for an airy tail • Set dry/wet to 100% to hear only the reverb • Set decay time long, around 15 seconds • Bounce to audio, crop the reverb tail, and reverse it
    Create an audio effect track with three chains: original pitch, plus five semitones, and minus seven semitones (full octave below the second chain) to create an ethereal chord-like vocal sweep.
    • Pan original pitch and plus five chains to opposite sides for width • Add EQ to clean up low-end rumble • Sidechain the sweep to the kick using a low pass filter to create a pumping effect
  • Turning Field Recordings into Textural Pads(11'11 → 14'03)
    Load a field recording and use ProQ4 with maximum Q setting and maximum gain boost on specific note frequencies (like all C notes) to make them resonate in the sound.
    • Duplicate the first ProQ4 to fine-tune balance • Adjust percentage on the second EQ to balance resonances against the original field recording • For EQs without piano roll, manually input note frequencies using a frequency chart
    Bounce the boosted field recording into a sampler, normalize it, then use very slow attack and long release settings to turn it into a playable pad for cinematic chords.
    The field recording shifts along with the notes, moving up and down in pitch as you play, creating a raw and cinematic sound reminiscent of the Burial's Untrue album.
  • Granular Synthesis for Textural Loops(14'03 → 20'14)
    Granulator is a granular synthesizer that slices audio into tiny fragments of sound called grains, ranging from just a few milliseconds to several seconds long.
    • Position dial sets the spot in the sample being read • Scan control moves the playhead forward automatically and indicates scanning speed relative to the sound's original pitch • Shape controls how each grain fades in and out, creating stuttery choppy effects • Variation randomizes each grain's starting point around the chosen position
    Modulate parameters with the built-in LFO while recording, capturing multiple textures with both soft fade-in and sharp plucky grains to create dynamic variation for slicing later.
    • Apply OTT multiband compression around 13% to clean up low mids • Tighten low end with EQ and boost around 2K for clarity • Use audio effect tracks with ping-pong delay and pitch shifter chains to add depth and dimension
  • Envelope Followers for Dynamic Movement(20'14 → 28'25)
    Envelope followers capture the volume envelope of one sound and map it to control parameters in other devices, creating dynamic movement based on the source's dynamics.
    • Map trumpet envelope follower to bass amp input gain to create distortion following trumpet peaks • Duplicate envelope followers to map to different parameters like presence and reverb • Use delay parameter to make modulation lag slightly behind the input signal
    • Map envelope follower to chorus amount so louder notes increase chorus • Link to vibrato to make vibrato move with pluck volume • Map to delay dry/wet to add delay that increases as notes get louder
    Envelope followers work for both aggressive dynamic transformations and laid-back ambient textures, making a static sound evolve into something continuously dynamic.
