Interstellar Space Machine.

Create expansive soundscapes and evolving, otherworldly tones. Add layers upon layers of harmonic and rhythmic complexity within an enveloping stereo field. Infuse your rack with vintage warmth and retrofuturistic soul.

Tape Delay, Looper, And More.

Packed with powerful features while maintaining intuitive playability, Magneto is a stereo multi-head tape delay that also functions as a looper, phrase sampler, vintage spring reverb unit, phase-aligned clock multiplier, chaotic oscillator, zero latency sub-oscillator and more, with extensive CV I/O.

 

Transform Your Modular.

Turn simple monophonic signals into complex orchestrations. Create new oscillator tones using self-oscillation. Add rich stereo dimension to your sound, and enjoy the inherent warmth and sweet, subtle distortion characteristics of magnetic tape. Magneto transforms even the smallest rack into a fully expressive, immersive instrument.

Vintage Vibe.

To capture the full experience and complexity of a vintage tape echo machine, every last tape system attribute was relentlessly studied and faithfully recreated. From the sought-after natural saturation and soft clipping of magnetic tape when driven hard, to hands-on real-time controls for tape age, tape crinkle, and mechanical wow and flutter, Magneto delivers a rich multi-head delay experience that adds life and vibe to your sound.

Play It Like An Instrument.

Every function, control, gain stage, and signal path component in Magneto works together to respond musically and smoothly, even during the wildest live modular improvisations. All this is combined with a luxurious spring reverb to take the sound of your modular setup to a new level, and your sonic explorations into far-out territories.

  • Warm Up Your Rack

    Not only does Magneto deliver the warm, luscious delay signals that tape delays are known for, it is also capable of a high degree of saturation. Turn up the Record Level knob to send a hot signal to the record head for any amount of tape saturation you desire. Turn up the Tape Age control for warmer repeats. Add some truly beautiful Spring Reverb. Magneto adds organic heart and soul to the sound of your modular.

  • Otherworldly Oscillator

    Tap in a fast delay time, crank up the REPEATS knob, and Magneto launches into beautifully singing self-oscillation. Magneto will find evolving tonalities determined by the SPEED/PITCH setting (knob or 1V/octave CV), and the LOW CUT and TAPE AGE knobs. Press the INFINITE transport button to capture a particular tonality. Switch to Pitch Quantize mode and as you turn the SPEED knob, Magneto will play within any of 15 selectable scales.

  • Pitch Shifted Delays

    In SHIFT mode, Magneto creates rhythmically pitched delays by changing the playback speed of each of the playback heads. Head 1 plays back up one octave and a fifth at 3x speed, Head 2 plays up one octave at 2x speed, Head 3 plays down one octave at half speed (creating deep bass sounds), and Head 4 plays quarter note repeats with no pitch shift. Use SHIFT mode to make things bigger and deeper, and to add melodic and rhythmic content. In SHIFT mode, Magneto is also easily configured as a powerful zero-latency sub oscillator: Just run your gate signal to the Restart CV input and blend in only Head 3 with the DRY signal.

  • Spring Reverb

    Some of the classic tape echo machines included small integrated spring reverb tanks tuned to limited bandwidth. For Magneto, we captured this vintage vibe while creating a flexible, beautiful spring reverb that stands on its own, in addition to enhancing delayed signals. The reverb circuit’s gain structure is designed so that when pushed hard, it will trash up nicely to hold its own with the funkiest lo-fi units, but when the input level is backed off, the reverb has a gorgeous, gentle character that enhances even subtle passages in a sophisticated and spacious way.

  • Sound on Sound

    Just like one of our favorite moving head tape echo machines, Magneto gives you a Sound on Sound mode (LOOP Mode).

    When you enter LOOP Mode, the machine is already recording, just like a traditional tape echo machine. Tape head 4 is the looper playback head while tape heads 1-3 provide delay repeats for the incoming signal. To set the length of your tape, press Tap once to set your splice “in” point, and press Tap again to set your splice “out” point. All of the tone shaping knobs are active and affect your loop as it plays back and re-records. Press Tap a third time to completely erase the tape. The REPEATS knob controls regeneration strength. Set lower REPEATS level for loops that evolve over time. The maximum loop length is 15 seconds at max SPEED, or two minutes at minimum SPEED.

  • Phrase Sampler

    Magneto includes a Phrase Sampler for recording a loop that is the length between two taps of the TAP button. Just press the TAP button once to start sample recording, again to stop recording, and a third time to clear the sample memory. You can trigger sample playback with the RESTART transport button or via the RESTART CV input. The Speed knob or Speed CV determines the pitch and speed of the sample playback.

  • Infinity and Beyond

    Want to just let Magneto continue to generate a soundscape while you play with some other modules? In ECHO mode or LOOP mode, just press the INFINITE transport button at any time to disable the Record head and allow Magneto to continuously play the most recent delay cycle or loop length audio. You can also engage INFINITE and use Magneto as an oscillator.

  • Flip It And Reverse It.

    In ECHO mode, the entire tape contents (not just the current delay time) are played backwards when you press Reverse. This allows for some very trippy effects when playing back sections that included SPEED manipulations or PAUSE events. In LOOP or SAMPLE modes, the loop or sample length will play in reverse. You can continue recording new audio to layer with the reversed audio from the tape.

  • Phase Aligned Clock Multiplier/Divider

    Each of Magneto’s four tape heads has its own Clock CV output, phase aligned with incoming Clock or Tap CV signals. In ECHO mode with EVEN head spacing, Head 1 outputs 4/1 (16th notes), Head 2 outputs 2/1 (8th notes), Head 3 outputs 3/4 (dotted 8th notes), while Head 4 is 1/1. Different values are available in TRIPLET and SHIFT head spacings.

  • Mechanical Tape Stop/Start Effect

    The PAUSE transport control is part of Magneto’s faithful recreation of a varispeed tape delay, with mechanical slowdown when pausing and mechanical speedup when coming out of pause. The speed of this mechanical slowdown/startup effect is user-definable.

  • Scrub Your Audio Clean.

    When the transport has come to rest after Pause is engaged, the Speed knob acts as an audio scrub tool. The length of audio in the scrub buffer is determined by the position of the Speed knob when Pause is engaged, from 750ms at maximum speed, to 6 seconds at minimum speed.

  • Stereoize Your Modular

    Double your dimension. Even if everything else in your rack is mono, plug into Magneto’s left input and enjoy instant stereo gratification. Each of Magneto’s four playheads can have their outputs panned hard left or right (or center). There are three pan modes: LRLR, LRRL, and (customizable) Center. With all heads centered, a psycho-acoustic stereo image is produced. Adding Wow and Flutter or the built-in Spring Reverb enhances the stereo field even further.

    The effect of the Low Cut and Tape Age knobs are explored, followed by the mechanical ‘deterioration’ of the machine with the Crinkle and Wow and Flutter controls. The Speed knob is put to use for sonic enhancement.

  • Shift Head Pitch and Rhythm Manipulations

    The Shift Heads mode creates a synchronous, rhythmic musical production that results from the playback heads running at different speeds.

     

  • Record Level Saturation Effects

    The tape drips with saturation when the Record Level is turned up. This example shows how things can get good when you push the limits. The Low Cut and Tape Age get in on the action for good measure.

  • Multi-part Orchestration from Mono Input

    A slow sequence is transformed with the Shift Heads while the Infinite transport CV is toggled using one of Magneto’s own clock outputs.

  • Magneto as Sub-Oscillator

    Using Magneto as a zero-latency sub-oscillator is as easy as sending a Gate signal to the Restart CV. Adding feedback creates sub-octaves of the sub-octave.

  • Video Game Sampler

    Minor Pentatonics ruled the day in the arcades. Here the Phrase Sample mode is used to fire some lasers and score some points.

  • Funky Rhythms, Gated Reverbs, and Transport Manipulations

    Magneto provides the clock to a lively sequence and fills out the rhythm with delays and gated Reverb using the Spring CV input. The transport controls lets you manipulate the machine in a variety of ways. When the deck is stopped, the Speed knob becomes an audio scrubber.

  • Speed Changes While Following Clock Input

    Magneto gracefully re-syncs to the Clock CV input after Speed knob manipulations temporarily change the delay time and pitch of the audio that has already been recorded. An LFO connected to the Speed CV provides a gentle vibrato.

  • Magneto as a Chaotic Oscillator

    Magneto self-oscillates in ever-evolving ways as the Speed knob is manipulated to change the pitch of oscillation. Combining this with Magneto’s Pitch Quantize mode, or controlling the Pitch with an external 1V/oct CV results in a unique sound generator in its own right.

  • Creating Harmonies with Quantized Pitch

    A monotonic static input tone is morphed into a chordal tone generator by varying the SPEED knob while recording the incoming tone. The 1v/oct SPEED CV adds more possibilities.

  • Sound On Sound Looper

    Sounds are recorded at varying tape speeds in looper mode to create a full spectrum of slowly evolving sound-on-sound textures.

  • Adding Ambience

    A little free-form improvisation with Magneto providing a multitude of ambience.

  • Vari-Speed Phrase Sampler

    Magneto becomes a classic keyboard vari-speed sample playback machine by utilizing the 1v/oct Speed CV and the Restart CV inputs.

  • Guitar Sounds Through Magneto

    Why should synth players have all the fun? Here Magneto processes a guitar signal to create a new world of sonic possibilities.

  • Sci Fi Lo Fi

    Travel back in time when the sound of the future was ominous and unforgettable. Magneto completes the journey with vintage spring reverb and oscillating lo-fi delay tones.

  • Pause Speed and Fun with Transport Controls

    Magneto’s Pause speed can be varied from snappy quick to super slow. The transport controls invite spontaneous creativity, and smoothly transition back to reality when you decide it’s time.

Completely Analog Dry Path.

In a typical digital effect the dry signal gets converted to digital, causing conversion noise and latency. Signals are often attenuated before combining digital dry and wet, with makeup gain amplifying the conversion noise. To avoid this terrifying scenario, we’ve equipped Magneto with a completely analog dry path. Why go to all this trouble? Because the improvements in dynamic range and reduction in noise are so dramatic.

Insanely Powerful DSP.

generalissimo_sharcprocessor

We’ve outfitted Magneto with the incredibly powerful Analog Devices SHARC ADSP-21369 processor, which provides a 366 MHz core instruction rate, and an incredible 2.4 Gigaflops of peak performance. Thanks to this high-powered technology platform within Magneto, we had the freedom to craft our processor-intense tape echo algorithms without compromise.
