Harmonitron vs Drawtone

Harmonitron is a harmonic tremolo. The rich, swirling amp "vibrato" made famous by early-1960s brownface amplifiers. A normal tremolo just pulses your volume up and down. A harmonic tremolo goes deeper: it splits your sound into a low band and a high band, then sweeps them in OPPOSITE phase. As the lows swell, the highs dip and back again. That contrary motion is what gives Harmonitron its lush, watery, almost phaser-like character that an ordinary tremolo can't reach. Turn the Voice control and the effect morphs smoothly from a classic in-phase tremolo all the way to a full harmonic swirl. Drop it on guitars, keys, synths, pads, drums, or a whole mix. Standalone, or as an Audio Unit (AUv3) effect inside GarageBand, AUM, Logic, and other hosts. THE SOUND • True harmonic tremolo: anti-phase modulation of a low and high band • Voice: morph continuously from classic tremolo to full harmonic swirl • Split & Tilt: place the crossover and balance the two bands • Tube Drive and tone shaping for warmth and grit MOVEMENT • Rate from a slow tide to a fast flutter, shown in BPM • LFO Shape: sine, triangle, square, and ramp with adjustable edge Slope • Tempo Sync that locks to your project and lands on the beat, with musical note divisions from 1/1 to 1/32 (dotted and triplet) • Stereo Spread for auto-pan and rotary-style width HANDS-ON • A living hero orb whose two halves breathe in opposite phase — drag it to set Depth, tap to bypass • Grouped, color-coded controls: Motion, Sync, Harmonic, Stereo, Drive, Output • Factory presets: Brownface, Rotary Swirl, Slow Tide, Sync Chop, Wide Harmonic and more — plus your own saved presets PLUGIN & STANDALONE • Full AUv3 audio-effect support with host presets and parameter automation • Runs on iPhone, iPad, and Mac • Standalone mode with a built-in demo pad, live microphone input, or import a song and export the processed result

Draw a mountain. Hear a sound climb its slope, rest a moment at the top, then come slowly down. You don't need to read music. In Drawtone, music starts with a line: drag a finger across the paper and it plays before the line is even finished. Whatever you draw is in tune; every line lands in the scale you chose. A long line is one long sound. Not a stutter of beeps; a sound that lasts like a breath and bends wherever your line bends. COLOUR IS THE SOUND A warm colour strikes like a string. A cool colour stretches like a bow. Six voices, six colours; stack them up and they never drown each other, each stays in its own place. OPEN A WATERFALL, THEN DRAW YOUR OWN Fifty drawings from nature are waiting inside. The waterfall is a marimba pouring down. The fireflies are single touches lighting up in the dark. The crane is one long line in Nihavend. Open one, listen, leave your own line on it. Your own drawing is not lost: undo brings it back, key and tempo included. DRAW HICAZ Hicaz, Uşşak, Nihavend, Hüzzam, Saba: the Turkish makams sit in the same list as the Western scales, not hidden in a submenu. The same line is a morning in Lydian and an evening in Hüzzam. THE PULSE The dot in the header beats with what you hear. Tap it: tempo, rhythm, swing. If you like, a light drum kit holds the floor underneath. Off by default; the first thing you should hear is your own line.
