hi all,

I have this math transformation: numbers from a to b becomes to numbers from c to d, where d goes exponential higher.

for example: I need to make [expr] object, and when I send 1 it outputs 1 when 10 output 1000

m*exp(n*$f1)
where
m=c^(b/(b-a))/d^(a/(b-a)), n=log(d/c)/(b-a)

this is the math but I don't know how to put it in [expr] object

can anyone help

Hello everybody,

I want to make electronic variant of this musical instrument, so my idea is to change the sound of it by changing the distance of my hand or leg, coming closer and the opposite. I use distance sensor and arduino for this and piezo plate and amplifier to take a sound, and I make this patch. I add the frequency from [~osc] to the sound from amp.

The problem is that, there is a noise and when I change the [~osc] argument it makes a sound that I don't want.

First I tried with [~bp] filter but the result is unsatisfactory, after it I tried with [snapshot]. I tried to select the numbers higher than this noise and I add the frequency from [~osc] only to this parts of sound, but it not works fine. May be I miss something important, or I have to change the way of solving of this problem.

Please help.

Hi all
I am new in Pd, so I try to make something like a sound effect. In my example i have[adc~] ->[dac~] , between that I have

• [osc~] witch add a frequency to [adc~]. My question is if I have beat on my line in, can i select this bets and add this [osc~] only to places where I have sound. I tried with [snapshot], but I' not satisfied from this result.
  Can anyone help.

Hi all, I am new in pure data, so please can anyone help me. I want to read html code from internet browser and use to make sound from it, but i don't know witch objects i can use to do this, I would be very glad if someone can help me. Thank you in advanced. Best regards.

OK, now I have success,

Hello, this topic is my last hope:).

I am working on a project, and I'm using the same device, unfortunately I have the same problem.

I tried this. The object works and it conects to headset, but there is nothing in number boxes.

Maybe I had made a stupid mistake with something?

please help

!thanks:)

O.K. What I want to do is something like changing the equalizer, when I change the [osc~] argument I whant to change the sound of Cajon.
The problem is that when I make the argument higher I have a sound with out hitting the cajon because the amp makes noise.

Sorry, but I am new in PD and maybe I can not express myself properly.

Thanks

OK, looks good:)
Thanks a lot.

thanks a lot
