Modulation Super Powers for Ableton Live!


7 incredible Max For Live devices conceived to shine a new light on the power of modulation

  • KNOR – Gestures sequencer
  • LFOH! – Advanced LFO
  • LFOO – Complex LFO
  • Sources – 3 signals to 1 target
  • Targets -1 signal to 6 targets
  • Voltage – Modulation to CV
  • MIDI – Modulation to MIDI


Gestures Sequencer

A spin of modulation! Create and playback free hand gestures, recall them manually or via a probability-based sequencer for unpredictable modulation joy. An immediate and playful tool, amazing for improvisation, in performance and in the studio. Addictive if paired with a MIDI controller!



Advanced LFO

A tool you already know, with the most advanced features. Morph, swing, squeeze, and more: twist your modulation waveform as never before! Simple and powerful.



Complex LFO

Complexity, through control. Two highly shapable LFOOs, combined via math operators to generate a third waveform. Modulate up to 3 targets, with 3 networked sources. Full control, gorgeous visual feedback.


Sources + Targets

Modulation Routing!

Create a complex modulation signal by combining up to 3 modulation sources.


Take one signal to modulate multiple targets. Create complex networks of relative/synced modulations in a breeze.


Voltage + MIDI

Modulation to CV and MIDI

Easy and flexible, Voltage and MIDI are your smartest way to route any modulation signal thru the external world as CV, Gate,Trig, or MIDI messages.

With 3 color schemes, Voltage and MIDI offer quick visual feedback for your patching cables or gears.

Full Details

KNOR is a Max For Live device that allows for playful modulations over any automatable parameter inside a Live Set.

The name comes from the contraction of the words “Knob” and “Record”, which is explanatory of its main key feature: KNOR is capable of recording free, hands-on gestures for each of its four dials, playing them back continuously.

Dials can be activated singularly or sequenced one after another, in favor of creating unquantized, always changing modulation signals. Mapping a simple MIDI controller to KNOR makes everything more intuitive while playing around with it.

LFOH! is an augmented, stunning Max For Live LFO (as the name suggests!), which enhances the possibilities of the classic cycling envelope by adding control over a set of advanced and unique features. It can be used to modulate any automatable parameter within a Live Set. Some of the parameters found on its interface are pretty standard, while others are a bit more special, allowing for advanced real-time waveshaping of the modulation signal.

LFOH! is a single oscillator LFO and has a set of continuously morphable and selectable waveforms that represents the core of our final signal. Apart from the classic Frequency and Phase parameters (which make it capable of all of the classic modulation stuff), the waveform can also be shaped by swinging its cycles, bending its curve, squeezing portions of oscillations in the same period of time, scaled and transformed while exceeding its boundaries. An additional Sample and Hold circuit provides quantization for the resulting signal.

LFOO is a Max For Live device that allows generating complex cycling modulation signals and multiple targeting. Its core idea is to combine two waveforms into a resulting third waveform (with its own set of parameters).

Three assignable targets are available to modulate any parameter in a Live Set. LFOO is made out of two continuously morphable waveforms that are processed by some usual (Phase, Amp, etc…) and unusual (Swing, Squeeze, Bend) parameters, acting as independent sources.

The third modulation source is derived by the result of selectable operations between the first and the second waveform. Up to three modulation targets are available and each target can get its own source either from oscillators 1 or 2, the third waveform, and a noise generator.

A color coded layout is used to keep the interface quick and easy to read, changing the target’s color in relationship to the assigned source. Two of the three targets offer a delay parameter, while the first one offers an integrated Sample and Hold circuit to quantize its output.

Sources is a Max For Live device conceived to combine three modulation signals in different ways by carrying out math operations and DSP processing between them. The resulting signal is then available to modulate any parameter within a Live Set.

Sources has three dials that can be mapped to be controlled by other modulators, with control over their individual amplitudes. If nothing is mapped to them, they act as standard offset generators.

A set of different operations is available to combine the three in series: the result of the operation between the first two dials is then processed by the third operation and combined with the third one. The resulting waveform can then be mapped to control other parameters and fine tuned by taking advantage of Transform and Smooth settings.

Targets is the complementary Max For Live device to Sources. It can be used to route a modulation signal up to six different parameters in the Live Set, each one able to process it in different ways. It can also be used as a super-macro-knob.

It can be especially useful to control multiple parameters of a single device, or even multiple devices at the same time, while keeping modulations consistent between each other.

The Source dial can be mapped to be controlled by any other modulator. Its output is then distributed across the six different targets, each with its own set of controls to transform and shape the main modulation signal before routing it to its respective destination, which can be set by mapping the correspondent target.

Voltage is conceived to easily route any modulation signal to any available output. It’s primarily focused on controlling external CV gears, such as modular synthesizer, by taking advantage of a simple interface that makes it easy to keep track of each instance. The device also has some internal parameters that help calibrate its output signal to properly talk with the respective converter. In order to use Voltage and route modulation to external outputs, a DC-coupled audio interface is required.

MIDI shares the same interface and functionalities of Voltage, though getting the modulation signal translated into MIDI messages no polarity setting is provided. It also has an additional destination parameter, since the address of a MIDI message is composed of an output, a channel and a number.
