Hello all!

I’m new to this forum! However I’ve been working with Pd for a while. Currently I’m programming a polyphonic synth in Pd with FM capabilities and I’m facing a problem. I have created some sort of a module which includes one oscillator, a low pass filter and an ADSR envelope generator. The output of this module is an audio signal. It also includes some inputs and one of them is a signal input for frequency modulation (it receives a signal from the outside and uses it to modulate the frequency of the oscillator inside the module). I use clone command to create multiple instances of the same module to make it polyphonic. Then I tried to route a signal from another cloned module to the FM input of the first module and the obvious ocurred: when I play only one note the FM works as supposed to. But when I play multiple notes it sounds terrible and it is because the audio signal of all the notes from the second module goes to the FM input of the first module and then it is routed to all the cloned instances of it. What I need is to route only the signal corresponding to one note and route it to the same note of the first module. Is there any way to achieve this? I understand that a signal goes equally to all instances of a cloned object, but is it possible get separate signals from all instances of the second module and route them separately to the corresponding instances for the first module?

@djaleksei You can route separately to specific modules within [clone] by including the clone number in the [send~] and [receive~]
You do that using $ in the name.
Clone 1 will assign the value of 1 to $1...... clone 2 the value 2...... etc,
So if you use [receive~ $1-modulation] then each cloned module can receive separately.
If each osc module is to be paired with each modulation module thenit is a simple task...... putting [send~ $1-modulation] in the modulation cloned abstraction will have fmmod1 send to osc1, fmmod2 send to osc2 etc.
You can give [clone] more arguments..... giving you the possibility to use $2, $3 etc. for more complexity...... i.e. if you one day add another bank of cloned oscillators to your patch.......

@whale-av Thank you very much for your reply! In my case I need to route signal outputs of each cloned object inside one module to another cloned objects inside another module. What I mean is that the first module receives signals from outside of it. I don’t need to route signals between instances of cloned objects inside the module, what i need is to direct multiple signals coming from different instances of cloned objects inside one module and send them outside and then send them to cloned instances inside another module. Hope I managed to explain well enough. Thanks a lot!

This works with @whale-av 's suggestion.
@djaleksei You want to route signals from different instances of one cloned object into different instances of another cloned object?

[s~][r~] and [throw~] [catch~] might be the cheapest CPU- and patching-wise

(and [poly] might be part of your interest.
with [switch~] you can turn instances on/off)

@lacuna Thank you for this information. However, I'm having a really hard time trying to wrap my head around this. As far as I understand, you can use s~ and r~ to route signals from the cloned instances to other cloned instances but can't figure out how to do that. Here is a very simple example explaining what I'm trying to achieve, The idea is to modulate the frequency of each cloned instance inside the second module with signals coming from corresponding cloned instances of the first module, so each note can be modulated separately.

The cloned modules on the left will send and those on the right will receive.

@djaleksei To make sure that you don't get one block of delay by the [s~] [r~] or [throw~} [catch~], add a dummy i/o and connect the sending and receiving objects:
This ensures [s~] is created before the corresponding [r~], just as described in help>audio examples>G05.execution order with delay lines and subpatches

@whale-av I got it! Thank you very much! It worked very good, but I get these warning messages:

warning: 0-fm: multiply defined
warning: 1-fm: multiply defined
warning: 2-fm: multiply defined
warning: 3-fm: multiply defined
warning: 0-fm: multiply defined
warning: 1-fm: multiply defined
warning: 2-fm: multiply defined
warning: 3-fm: multiply defined

Is that something I should worry about?

@lacuna it seems to work fine without the dummy i/o but I will implement it to ensure no delay is generated.

Thank you very much guys! You helped me a lot!

@lacuna I also tried to do this, but each time a note is played there is a click and also a small delay. Looks like it has to do with loadbang, but I'm not sure... What I want now is to be able to route the signal to the outsite of the cloned object so I can patch things outside of it.

@djaleksei The [loadbang only happens as you load the patch.... so that is not the source of the clicks.
It's likely that you need to soften the output of [!= 0] using [line~] so that the [osc~] output is taken gracefully up and down..... just a few milliseconds should do it.

You can route outside with [send~] / [receive~] or [throw~] [catch~]

This might be a good time to zip up your whole patch and post it. Make sure all the parts are in the zip file, and describe in the patches what you are trying to achieve.
It's hard for us to rebuild it from screenshots for testing.
