Multiply module doing nothing

Hi,

I tried to multiply something and it seem to do nothing

Just for testing i put a multiplier between a cutoff knob and the filter.

If i give 1 for value, meaning i multiply by one, it's supposed to change nothing, but the cutoff knob do nothing, it's dead, not changing the cutoff sound like is suposed to do. I tryed all Multiply, int, float or stream but nothing happen.

For example, suppose i want that the cutoff knob move a little bit the filter resonnance value as i raise the cutoff knob, i will connect the cutoff knob to the res filter and multiply it by, said 0.01

But it's doesn't seem to work

Is there a kind of volt meter that we can see if what we are doing is really working?

Someone can help?

Cheer

Without the schematic it's pretty hard to say what's wrong...

Could be that you've used the wrong multiply component. There are three based on the data type of the output but with limitations on the input.

You can attach a float value to one input of a stream multiply but not two or it won't be a stream.

Similarly, you can't feed a steam to an integer or float multiply component as the stream is data at sample rate and cannot be attached directly to a green component.

Sorry if you know all this already (I'm assuming from the softplug site that you know more than the basics of synthesis) but it hard to say what might be wrong without seeing the OSM.

try this FILE

it is about as simple as it gets, notice the multiply is a 'stream multiply' because you are multiplying audio stream data. green data such as floats and ints are equivalent to SE subcontrol data. Like Odson said - You can connect a float to a stream multiply , but you cant use a float multiply to multiply streams.

there is an lfo module that comes with SM which you should probably use, it's better than this.

notice that the oscillator gates automatically when a midi note is pressed, this is unlike SE where you would need to connect a trigger to the oscillator.

Ok, thank you,

I'm not used to this, i didn't took a float to enter data. I took a sting a that's why it didn't worked.

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.
