harmv2~ (Harmonizer)

> (I have a concert coming up next week in NYC and time is of the essence.)

You're lucky. In another thread [message #165739] I just posted an example of such a thing. It's based on the same technique as harmv. It's the basics, you'll need to work on it a bit.

In the examples folder of Max, there's something called "transposer" which does basically the same thing as the widely known harmv2~.

Best,

Johan: That's close but still not it. I need to spend a little time with your patch to see how it actually works to get an idea of how to modify it.

EJ:

I looked at transposer~ and that handled the pitch side of things but doesn't get to the delay that the abstraction harmonizer did.

The options on the IRCAM Harmonizer are a transposer, window size, delay, and output for both left and right channels. There is also a global volume for the entire output. Attached is pic to get an idea.

As it's an abstraction you can modify it. To add the delay feature to transposer you just need to add an offset to the signal you send to tapout~. That's how harmv2~ works.

Thanks ;-)

EJ< I think I see what you're talking about. I opened the transposer and saved it as another file so I didn't mess up that one. When I opened it though I could not edit it. Is there a way around that?

Thanks,

Mark

If you do something like that and save it as transposer2... then you have something close to harmv2~.

Note however that harmv2~ have the tapin~ outside, but that's just a question of taste. You need to provide the maximum delay time as argument in this abstraction.
I hope there's no patent on harmv2~;-)

I have a harm2v~ replacement in the CNMAT MMJ Depot at:

http://cnmat.berkeley.edu/downloads

In fact, there is a lot or really shady math in that IRCAM harmonizer. I think the one I made is much better. Here are the guts, I also have a help file and a wrapper to make it drop into place for harm2v~:

But your version is far easier to understand. With the Ircam one, students get more the feeling of being rocket scientists ;-)

Hello,

Below is the harmonizer patch from the elastic videos, might be of some use...

It uses fiddle~ to calculate the midi note value of the incoming (monophonic) audio, then a js file that transposes by a set amount and then rounds up this transposed note to fit in to a predetermined scale. This is then converted to a transpose ratio which, in this case, is fed in to an elastic~ object. (Other pitch shifters are available!)

//// js file save as "transpose_to_scale" ////

var transpose = jsarguments[1];
var note_array = new Array();
var note_str;
function list(a)
{
note_array = new Array();
var i;
for(i=0;i
{
note_array[i] = arguments[i];
}
note_str = note_array.toString();
}
function msg_int(a)
{
var note1 = a + transpose;
while(note_str.search(note1) == -1)
{
note1++;
if(note1 > 150)
{
break;
}
}
outlet(0, note1);
}
function set_transpose(a)
{
transpose = a;
}

// end of js file //
