Hello everybody . before i buy robertsonic wav trigger i want to make sure it does what i want. - random choice of a piece of music. - many songs stored in local memory. - when the playback of the song ends, it restarts automatically or a different song starts automatically, and so on. all this by closing a single button. it’s possible ? ---
