TM4-LUX is our hi-tech the best selling product. We recommend it because it gives you the most. It contains all our hardware and software solutions on the left and right sides of the accordion.


It is the world’s only MIDI system with the patented TOTTER MIDI QUINTET® function (enables you to simulate a 5-piece band, Alpine quintet, or ensemble), TOTTER MIDI GUITARIST® (enables you to sound the chord by simply playing the bass) and ACTIVE CHANGE® of instruments.


With the grille mounted control panel, the use of the TM4-LUX model is combined with the movement of your fingers when playing the accordion.


When standing on stage you just select your favorite preset instrument combinations from the 100 internal memory locations. Prepared settings, which you can customize and save on your own preferences without using your computer, will satisfy every musical taste. With the TM4-LUX you will enjoy all kinds of music – Polka or European, classics, Jazz, Ballroom, pop, rock,…


It is pleasure, when everything is heard, as you wish!
Make sure on your own ears!


To operate the TM4-LUX model built into the accordion, you need a sound generator, for example, sound module (SONATTER TM4), synthesizer, keyboards, computer, … and active speaker.


You can test all our products yourself!
