Sampo Components

Sampo is composed of a wooden box containing the electronic equipment and a set of continuous variation pedals.

The box contains all the elements to capture, process and play sound.


The pedals are plugged on the front pannel of the box. The microphone is placed in the compartment at the back of the box.


Starting up and stopping

Sampo starts up with a button located above the touch screen.

To turn off Sampo just close the lid...

Wifi / Internet

Sampo can be connected to the internet via wifi. Sampo can thus receive the new configurations of effects and new parts upon request from the musician. Configurations and pieces appear directly in the menu without any intervention and are ready to be used.


Sampo can be transported in two different ways - either with two suitcases, one for transmission and one for the pedals, or in one case (flight case) especially when shipping Sampo by mail.

Sampo weighs approximately 8 kg and all pedals weigh 10 kg. If the elements are all gathered in one suitcase, it weighs around 20 kg in total.

Sampo Manufacturing

Sampo is manufactured in several workshops in France. First the wooden box needs to be manufactured to contain all the electronic elements:

This is the final result:


The box is then varnished and decorated by hand. Each Sampo is unique and original.

The purpose is to allow musicians to have an effective way to produce "live-electronic" music without any location constraint, even at home, and to play this music the way we play a classical instrument, improvising and having fun.

Mixed music pieces

Two types of pieces can be performed: the live-electronic pieces and tape music.

For live-electronic pieces, each continuous variation pedal affects one sound processing parameter (or more - it's the composer who decides) such as delay, transposition, feedback, decay and others. This way, the musician changes and adds sounds to his instrument following the pedal movements written on the score. The purpose is to add a new sound dimension to a traditional acoustic instrument.

In addition to the live-electronic pieces you can play tape music - in this case the musician uses four pedals:

  • to trigger the play and to move inside the file to facilitate rehearsals
  • output volume level of the instrument
  • output volume level of the tape,
  • Adding an effect (usually reverb).


The musician is thus completely autonomous - he or she does not need an assistant and can work wherever he or she wants, in his home studio or quietly at home ...

Sampo is easy to transport and install. You can play wherever there is an electrical outlet...
