Groovin’ with OscarUnderdog’s Two Squiggly LFOs
Introducing the Squiggly Duo
OscarUnderdog kicks off his video with an enticing promise: learning to make music with two squiggly lines, or as we know them, Low Frequency Oscillators (LFOs). These little waveforms are like your grandma’s hidden recipe for a killer beat. Oscar explains the basics using a sine wave—a line that goes up and down, hitting those positive and negative vibes—just perfect for modulating sounds. He sets the stage for a deep dive into sound sculpting, promising to show how these ‘squiggly lines’ can transform your music-making process. With a bit of humor and a nod to music legends like Kangding Ray and Rival Consoles, Oscar keeps it both educational and entertaining.

"And that gives you a shape like this."
Reason's Pulsar Dual LFO Magic
Oscar dives into Reason Studios’ Pulsar Dual LFO, demonstrating how this nifty piece of tech can be your new best friend. Picture this: two LFOs working in harmony like a dynamic duo straight out of a buddy cop movie. With both oscillators, he shows how to control the speed and triggers of a sound source. It’s like having an orchestra in your hands, manipulating the tempo and feel to create something truly unique. Oscar’s command over Reason makes it look easy as he navigates the virtual cables on screen. His enthusiasm for this all-digital setup rings through, proving that you don’t need pricey hardware to get that rich sound texture. In typical OscarUnderdog style, he teases the possibility of even converting this digital magic into MIDI, inviting viewers to explore beyond the basics.
Hardware Flair with Modular Synths

"And so now, just like in Reason, we can use the second oscillator to affect the speed of the first oscillator."
Transitioning from software to hardware, Oscar gives us a taste of modular synthesis with physical LFOs. This move is like switching from canned soup to a homemade stew, rich and hearty. He shows the beauty of tactile interaction, where you can physically crank knobs and get immediate feedback—a synth lover’s dream. As he patches and tweaks the sounds in real time, Oscar captures the essence of live performance, explaining how the second LFO can alter the first one’s speed, creating dynamic soundscapes. The climax is a thrilling jam that feels like it could drop into any underground club set list. His hands-on demonstration sheds light on how modular gear can offer flexibility that’s just a bit out of reach with purely digital solutions.
Ableton's Squiggly Symphony
Oscar swings over to Ableton Live, where he translates his squiggly LFO mastery into something anyone with a laptop can try. Using an arpeggiator to create unsynchronized magic, he layers effects to make beats that bounce with life. Unlike waiting in line at a fast food joint, tweaking LFOs in Ableton is all about the journey. Oscillators here act like skilled bartenders, mixing and remixing sounds in real time, ensuring the groove never goes flat. Oscar highlights the ease of mapping LFOs to various parameters, making it sound as effortless as snapping your fingers to a beat. His approach transforms Ableton from just another DAW to a playground for sound imagination, leaving viewers eager to start experimenting with their own tracks.

"Now we're sculpting."
Bringing the Groove Together

"So become a sound sculptor with two squiggly lines."
Wrapping things up, Oscar addresses the concern about loose beats and timing, showing how tweaks can bring everything together under a unified BPM. Like tightening a drum head, this section focuses on refining and synchronizing, ensuring that every pulse, every beat fits like a glove. Oscar’s final tip is about resampling sounds and aligning them just right, turning potential chaos into rhythmically stable tracks. It’s the kind of insight that could turn an ordinary beat into something memorable. Oscar’s encouragement to ‘become a sound sculptor with two squiggly lines’ sticks the landing, cementing the fun and formidable power LFOs can bring to music production.
