Name/Version: OCD43 Delay 0.4
Author: willum070  
Description: Updated with some minor tweax, plus see the JavaScript below which is critical for this to work.

The OCD43 is my attempt to reverse engineer the wonderful Lexicon PSP42 delay effect. I used the PSP Audio plugin as a guide, as well as the PCM42 hardware unit owner's manual. This was more of a learning experience than an attempt to create a carbon copy of the original. I intentionally left a lot of settings "under the hood", such as the overdrive, much of the LFO subsystem, the filters. Also I didn't implement phase inversion as is present on the PSP42. You can always open it up and change stuff if you don't like it, it IS MaxMSP after all! You can get all kinds of great delay sounds, from saturated dub echoes to flanger-like effects (set up the LFO on sine wave and try shorter delay times). Increasing the overdrive level will also boost the feedback. I constrained the input values to try and keep everything coherent. If you make any changes or have any ideas, please let me know!

Some notes: there is a limiter on the output channel.

The "wave" knob in the LFO section fades between the two selected waveforms.

Some of the UI elements use the Envy Code R font (http://www.fontsquirrel.com/fonts/Envy-Code-R).

the .JS file needs to be in your Max path. Copy the following code, save it someplace in your Max path as converter.js:

var tempo = 0;
var msv = 0;
var sDivU = 0;
var sDivL = 0;
var div = .25;

function list()
{
var a = arrayfromargs(arguments);
tempo = a[0];
sDivU = a[1];
sDivL = a[2];
//post(a[0] + ", " + a[1] + ", " + a[2] /n);

calculateTime();
}

function calculateTime(){
if(!tempo || !div || !sDivU || !sDivL)return;
var dTime=(60.0*1000.0*parseFloat(sDivU))/(parseFloat(tempo)*div*parseFloat(sDivL))
dTime=roundOff(dTime,2)
msv=dTime
bang();
}

function roundOff(x,nrDec){
fact=Math.pow(10,nrDec)
x=Math.round(x*fact)
return(x/fact)
}

function calcTuplet(myForm){
var tuplet=myForm.selectTuplet[myForm.selectTuplet.selectedIndex].value
var nr=myForm.number[myForm.number.selectedIndex].value
var noemer=tuplet.substring(tuplet.indexOf("/")+1,tuplet.length)
myForm.subdivisionLower.value=noemer
myForm.subdivisionUpper.value=nr
myForm.division.options[2].selected=true
calculateTime(myForm)
}


function bang() {
outlet(0, msv);
}

This is the Max abstraction that you can use with the script:

OCD43 in 2011! WOOOOOO!!!!

You might check out the translate object. It'll do a lot of what your javascript is doing.

Nice!
Can you add the repeat button and the mod capability too??

See an example here:

Cheers!

cool!

instantly creates a huge undo history!
