I read that Wiki, but it does not solve the issue, I can play either one track at a time, or a playlist in sequence or as a shuffle, or a playlist all at once. I cannot combine this functionality. I want to have a playlist playing a sequence of music... and without stopping it from playing i want to be able to play other sounds that i use for sound effects and ambiance. A year ago when i last ran a game on roll20 you could do this starting and stopping any track any at any time without affecting other tracks playing in any way, now you cannot. The way things work now it is not possible to use sound effects if you want background music or visa versa as playing the sound effect stops the music unless you play them as a combined playlist in which case the sound effect either loops over and over or plays at the start and is done. For example my group enters a creepy graveyard so i want to start some creepy haunted type music. Now they decide to go to a particular masoleun and open a gate, i want to play a sound of the gate creeking, but if i hit play on that gate sound the music stops which badly hurts immersion, then i have to restart the music from the begining. I want the music to keep playing but be able to play that sound effect on demand. If i did a playlist where they played together as soon as i hit play the music would start and gate sound would play and be done, long before they said they were opening said gate.
