This article presents an exploratory study of two groups of university students, one with musical education and the other without, and their thoughts on the use of the 'Soundcool' system. It is a technological tool designed for collaborative sound creation through mobile devices and tablets. After intervening with this modular system in the field of initial teacher education in the Master's Degree, a survey was designed and taken by two groups of students from two Spanish universities, with a total of 66 participants. Using musical education as a comparison variable (with vs. without previous musical education), our analyses focused on the following categories: experience with ICT, the relationship between ICT and education, the perception of the tool used and development of teaching skills. The results indicate that 'Soundcool', no matter what the musical formation of the participating groups is, is always perceived as a highly valued technological tool that can contribute to the development of intrapersonal and interpersonal teaching competencies; specifically, those related to creative development, collaborative work and innovation, fundamental in the professional performance of the future teacher. Also, in the conclusions, several contributions were made in relation to the use of this system. We invite the educational community in different educational musical contexts, such as music schools and conservatories, to reflect on the possibilities offered by using new technologies being used in the classroom.
