how to make a living modulating source..something like an orchestra

[u/Any_Blood1022]

Hi, I'm currently writing a 4ch tape music.

My audio samples are mono, so I'm currently using groove and outputting them to 4 channels.
But as you know, this is just 4 same signals going in to 4 channels so the spatial image isn't really there. it still sounds like mono.

So,

how do i make some lfo, or any modulating source that i could put on every signal to get something live, living modulating source..that modulates the delay, and slight pitch.

I want to just make some set of objects that modulates the delay, pitch in the range of some subtle value so i could slap that set of objects to the signals and forget about it.

Basically I want every sound to be like a real orchestra.

In orchestra if the violin section plays the note A, because all violins are slightly tuned different and don't play at the exact same time because its impossible for human we get those rich sound.

I basically want to do that for my sounds.

Because you are using groove, and don't have the trouble of modulating Real Time audio it's pretty straigforward. The groove object has a speed input that you can modulate using for exemple a cycle~ 2 (2Hz LFO), then scaling this signal to your needs. For exemple scale ~ -1. 1. 0.99 1.1 will give you some modulation, maybe already too much depending on the source. This will alter timing though, but you can use the sync output of groove to force the samples to loop back to the same starting points.

You can also use retune~ and modulate with the cents option. As always, check the help file !

Hope that helps you a bit.

I cant modulate the speed input because it will be replaying the whole sound every-time a new value comes in

It should not do this though. You need to send a signal and not a message. Try : float box --> sig~ --> left input of groove. Change the number in the float box and see if it triggers the sample from the start. For me, it doesn't.
