Hi,

i am still experimenting with the code module and oscs.

I am wondering why this small code does not work.

streamin in1; streamin in2; streamin SR; streamin vol; streamout out1; streamout out2; float a1, a2; in1=in1*SR*0.5; in2=in2*SR; a1 = a1 + in1; a1 = a1 - (a1 > 1) & 2; a1 = a1 + (a1 < -1) & 2; a2 = a2 + in2; a2 = a2 - (a2 > 1) & 2; a2 = a2 + (a2 < -1) & 2; out1 = vol*a1; out2 = vol*a2;

When only 1 input is connected the saw comes. When i connect the second input it does not work anymore 😊

Hi, These two lines are the ones causing all the trouble...

in1=in1*SR*0.5; in2=in2*SR;

Writing back to the input connectors is a big no-no in SM code, as it has strange effects on the components that are feeding the code module (the connectors are little more than shared memory addresses between components). A couple of temporary variables will soon fix the problem - and thanks to the way SM's compiler works will not cost you any extra CPU.

BTW) You can write to output connectors as many times as you like - only the final value will be seen by the following components.

Thanks trog I have set floats for the SR calculation. Now it works.

Before your first post

A few rules keep this a friendly place. You agree to them once.

Shown next to what you post, here and in the app. It doesn’t have to be your real name: 3–24 lower-case letters, digits or _ (capitals become lower case, spaces become _).

    Then your post goes up straight away.

    Open it in SynthMaker?

    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.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
