Hi! I am playing 2 frequencies like this: > play -qn synth $a_number_variable sine $sound_1 sine $sound_2 fade h $some $random $numbers and I am trying to play even more sounds like: > play -qn synth $a_number_variable sine $sound_1 sine $sound_2 sine $sound_3 sine $sound_4 or like: > play -qn synth $a_number_variable sine $sound_1 sine $sound_2 synth sine $sound_3 sine $sound_4 but that doesn't work. How would I do it to play 4 frequencies parallel with the same command? Is there no support for that and if so, why limit it to 2? Thanks in advance for any help!
