The timeFrogII is a tool in the midway between the MIDI controller and the MIDI instrument. The purpose is to allow the user to sculpt command messages sent to MIDI hardware and software.




The timeFrog II is a powerful and flexible MIDI device dedicated to music computer and MIDI applications.

The spin/inertial sensor provides a totally new kind of control surface, which opens new way for playing with parameters.

The 8 endless encoders,potentiometers and 6 buttons form a functional and compact device.

Premier exemplaire de la série timeFrogII

It can transmit and receive MIDI messages, offering endless possibilities for use of hardware and software that support MIDI, such Ableton Live, Max/MSP, Native Instruments Traktor and so much more.

A spin what for?

The spin allow the user to change a parameter with another feeling than a simple potentiometer:

  • large amplitude movement for a small variation.
  • control of the increment of the variation.
  • the spin can be launched and stopped, the variation stay under control using the increment parameter.
  • the spin can be automated, with 2 parameters for time control: increment and speed.
  • the spin can play a note and change his velocity, while a rotary controls the note pitch.
  • the spin can be assigned on any rotary and use his MIDI mapping to change his value, while automated or not.
  • the spin can fight against embedded sequencer.


3 globals modes:

  • controler: 16 controls or notes, including spin's one, by 4 pages
  • keyboard: 7 notes directly tunable: pitch, velocity, including spin's one
  • 4 steps sequencer: 4x4 stepsx6voices


The main concept of the timeFrog is that all runs over a central MIDI memory. Each modes offers a different way to use it:

  • controler: direct control change & note sending
  • keyboard: note sending + pitch and velocity edition
  • sequencer: sequence of controls or notes

The MIDI mapping is the same for all modes,

that means that the pitch of a note used by the sequencer can be changed in keyboard mode.

that means that the sequencer can change the value of a control in controler mode

that means that the spin control can be changed in the sequencer (and reverse)

... and the user can take over automations at any time.



Aluminium design, 6x10", spin on ball bearing. Robust and travel friendly.

Led indicator for rotary position, LCD 16x2. Feedback and ergonomy were tought in terms of efficacity.


Computer: USB or DIN5P, Mac, Windows, Linux. The timeFrog is complient to USB MIDI devices class. No need of drivers nor proprietary softwares.

MIDI devices: DIN5P, need of external usb power adaptator


The timeFrog is an open hardware plateform. The firmware stands under GPLv3 license. New functionnalities, new modes can be added, the whole device can be totally reprogrammed.

The possibilities of use are endless.
