Undulator is Eventide’s classic modulated tremolo effect from the iconic H3000 effects processor. This unique, rhythmic effect combines ethereal feedback and detuned echos, run through an AM / FM modulated tremolo. Whether used for manipulating samples or adding movement to strings, pads, guitars, and keys, Undulator is a muse for creative musicians. Add Undulator into your plug-ins collection for the most playable tremolo-style effect on your DAW or iOS device. Undulator excels at evolving pads, sync’d chops, and time-lapsing dreamy soundscapes. Combined with a multi-tap delay and powerful tremolo, Undulator’s controls give any sound sustain and shape. This is perfect for transforming ordinary synths, keys, guitars, and even vocals into evolving pads, tempo synced production elements, or ethereal and fluctuant delays. Simply put, Undulator can make shorter sounds into longer layered effects, and give sustaining sounds shape and rhythmic character. Use the Ribbon to morph tremolo patterns into vacillating and varying rhythmic territories. This can be effective for calling attention to synth pads and creating a state of flux or rarity which is otherwise arduous to achieve. - Turn up the MIX to increase the dry/effect ratio. - Utilize multiple modulation waveform shapes and sources to alter the rhythmic feel. - Subtly finesse detuning of delays by using SPREAD. - Add FEEDBACK to accentuate delays or create infinite loops. - The Secondary LFO determines how fast the depth and speed modulation “wiggle” their targets. - Lock the tremolo to tempo using SYNC. - RETRIG at the top of the waveform for a more predictable effect. - RIBBON lets you ‘play’ the effect in real-time and provides dynamic and fluid control to morph back and forth between the settings of your choice. - SLOW/FAST button toggles on a “Slow LFO” mode. Holding it down to “BRAKE” temporarily slows down the LFOs at a constant rate until released. - Update the tremolo speed in real time using the TAP button. - Available as an AUv3 plug-in and Standalone App.

The Quinta Pitch Machine is more than your standard octave in that it not only gives you notes an octave up and an octave down, but also gives you a fifth up. Each of the three intervals is dialled in proportion with its own knob, and you get a mix knob to blend dry and pitch-shifted sound, this runs from totally dry to totally pitch-shifted. Your Quinta Pitch Machine comes with 4 knobs. Three of these are used to add in the extra notes. The +1 OCTAVE knob adds a note that is 1 octave higher than the note you play on your instrument. The -1 OCTAVE adds a note that is 1 octave lower than the note you play. The +1 FIFTH adds a note that is a fifth higher than the note you play on your instrument. The last control on your Quinta Pitch Machine is the MIX control. This adjusts the balance between the natural signal coming from your instrument as you play it and the whole configuration of added octaves and fifths you have set up via the other knobs on your Quinta Pitch Machine. SONIC POSSIBILITIES - Octave up, octave down, 5th up - Individual volume controls, plus master mix - Replicate organ, synth or 12-string sound - Play power chords on a single note Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect
