playing more than 2 sounds with synth option

playing more than 2 sounds with synth option

[Noah Essl]

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!

Noah

Your commands create a new channel for each tone.  If you want to mix
them you can do that in a few ways.  One is like this:

$ play -n synth 10 sine 1k synth sine mix 2k synth sine mix 3k

Another way:

$ play -n synth 10 sine 1k sine 2k sine 3k remix -

If that's not what you're looking for, you'll have to describe in more
detail what you're trying to achieve.

Thanks for your input!
I tried several ways and I liked the "remix -" option the most.

What am I doing: I am programming a 4-voiced random music generator (in
bash) that endlessly plays in the background bc I am fed up with
available music.
Wanna try it: https://github.com/noahsmindfuck/random_music_generator

Is there a way to make the sounds sound like a piano instead of a pure
sine? Or can i actually import/use preexisting curves of existing
instruments (e.g. the 'pluck' that plays a guitar)?

Try 'pluck' instead of 'sine' in the synth command.

Why the extra invocation of 'synth'?
'play -n synth 5 sine 100 sine 200 sine 300 sine 400' works just fine.

Meaning what? What actual command are you using,
and what exactly is SoX doing? (That is to say,
show us the output of play -V synth ...)

Is your hardware capable of playing more than 2 channels?
If not, you will need the remix effect to mix it down to two channels.
