Reading Data

rl · 3 Mar 2006

Hi ginocote, I had bad luck connecting a volt meter, because I couldn't find the Gate. All I found was a free soundcard output slot and some unused USB connectors. But jokes aside, SM does not measure in Volts, but does in Brddls [Bd]. This was not covered in the documentation yet (since SM is still Beta). The SM system measures in units of [0..1] [Bd]. A Volt makes almost 10 [Bd] (The exact value is 9.81 according to the influence of the gravity on the electrons and the Heisenberg relation on Software bugs (you either spot their location or their impact, but not both at the same time).

But back on topic, to create a panner on note change use a Midi Splitter module on the midi input and create a trigger on new notes. Use these triggers to drive the panner. Hope this helps.

Thank,

How i create this trigger?

And how can i read these units? It is alway 1 and 0? No number in between?

In between Rudolph's jokes, I believe he was suggesting this...

OSM It reads midi-on notes and toggles between hard left and right pan. A more subtle effect could be had by some kind of smoothing filter.

The 'gate' is a poly-boolean value and can be used as a mask in a code module but I can't think of any (easy) way to use it to make this work.

edit-- I guess this isn't what you're looking for since it hard pans the whole signal left and right instead of based on the note... Making something the left the existing note with its original pan while the new note pans opposite would be harder... I'll give it a little thought.

What about having a poly "sampler" that samples the triggers value upon note on?

Something like

streamin in; streamout out;

stage(0) { out = in; }

Could work if you fiddle around a bit

oddson · 3 Mar 2006

Hey Stefan... haven't wrapped by brain around your suggestion yet...

...what I got was to filter the note on messages to separate left and right signal generators... not exactly efficient.

Here's the OSM is anyone want's to see.

stefan · 3 Mar 2006

The purpose of my suggestion is to be able to set the pan at the start of the voice, and then set it to whatever you want for each new voice that starts, without affecting already playing voices (because they sampled the pan at their start)

oddson · 3 Mar 2006

Like this!

polyin in; polyin toggle; polyout left; polyout right; float temp; stage(0) { temp = toggle; } left = in * temp; right = in * ( temp==0 & 1);

OSM

stefan · 3 Mar 2006

Exactly! It might be nicer to just have pan as a input instead of the toggle though, that way one could use this "pan sampler" for more things than just hard left/right panning. A matter of taste though!

btw, you're osm link is faulty (.png instead of .osm) 🙂

oddson · 3 Mar 2006

OK like this

polyin in; polyin pan; polyout left; polyout right; float temp; stage(0) { temp = pan; } left = in * temp; right = in * ( 1 - temp);

stefan · 3 Mar 2006

yeah. in the osm you posted, you should probably remove the "bool to false trigger", since when having that there, you won't get the right behaviour upon playing several notes simultaenously.

edit: ignore that. both gives you the wrong behaviour 🙂 mine works when holding notes, but not when playing one at a time, yours works when playing one at a time, but not when holding notes 🙂

oddson · 3 Mar 2006

Ooops - I thought I put a boolean to true there! Now I realize it wasn't needed anyway but I sure never meant to put the false on in there. 😊

edit- didn't catch your edit before posting. It's not 100% and I don't know why but it mostly works. I tried it with a boolean trigger switch and that has similar problems... oh well, that's as close as I'm going to get.

Thanks oddson, for helping out. This was what I had in mind.

I had no access to my SM workbench today and didn't want to leave ginocote alone with his problem (and my silly jokes), so I wanted to create an example later this evening. But you did save some of my time.

To add something useful to this interesting discussion:

How about omitting the midi logic and just using (not tested yet):

polyin in;

polyout left; polyout right;

float toggle;

stage(0) { toggle = toggle+1; toggle = toggle - (toggle > 1) & 1; }

left = in * toogle; right = in * ( 1 - toogle);

So after each poly process starts (stage 0) toggle switches from 0 to 1 and vice versa.

Hi ginocote, does this work for you?

Cheers.

stefan · 3 Mar 2006

But at each process start toggle will be initialized to 0...

rl · 3 Mar 2006

aargh, really? I thought, only if I put an explicit init code in. So, how could I define a "static" variable?

ginocote · 3 Mar 2006

Look good but don't know wich one really work.

Do you have a final .osm ?

In Synthedit we use a stepcounter. do the counter module do the same thing?

You might want to try the "Counter Advanced" primitive; allows negitive increments.

This OSM works as well as any and has a pan amount control.
