When singers control their own vocal effects during live performances, this is often done using floor-based or small desktop devices. However, if an artist presses foot pedals during a performance, knowledgeable members of the audience will know that he or she is making use of effects at that point and others may wonder why the vocalist is looking away and what he or she is doing with his/her feet. The loss of contact with the audience can be annoying in particular when readjustments are being made to the effects, and that’s before one even starts to take into account the curtailed freedom of movement on the part of the artist.
