//This shows how to use maximilian to build a polyphonic synth. // for some reason, chrome doesn't like this example? // maximTools will make it quicker to fill arrays with maxim objects var maximTools = new maximJs.maximTools(); var VCO_ArraySize = 6; //These are the synthesiser bits var VCO1 = maximTools.ArrayOfObj(maximJs.maxiOsc, VCO_ArraySize); var VCO2 = maximTools.ArrayOfObj(maximJs.maxiOsc, VCO_ArraySize); var LFO1 = maximTools.ArrayOfObj(maximJs.maxiOsc, VCO_ArraySize); var LFO2 = maximTools.ArrayOfObj(maximJs.maxiOsc, VCO_ArraySize); var VCF = maximTools.ArrayOfObj(maximJs.maxiFilter, VCO_ArraySize); var ADSR = maximTools.ArrayOfObj(maximJs.maxiEnv, VCO_ArraySize); //and these are some variables we can use to pass stuff around var VCO1out = [], VCO2out = [], LFO1out = [],LFO2out = [], VCFout = [], ADSRout = []; var pitch = []; for(var i = 0; i < VCO_ArraySize; i++){ VCO1out.push(0); VCO2out.push(0); LFO1out.push(0); LFO2out.push(0); VCFout.push(0); ADSRout.push(0); pitch.push(0); } //This is a bunch of control signals so that we can hear something var timer = new maximJs.maxiOsc();//this is the metronome var currentCount = 0,lastCount = 0, voice = 0;//these values are used to check if we have a new beat this sample var mix; function setup(){ for (var i=0;i=6) { voice=0; } ADSR[voice].trigger=1;//trigger the envelope from the start pitch[voice]=voice+1; voice++; // lastCount = 0; } //and this is where we build the synth for (var i=0; i<6; i++) { ADSRout[i]=ADSR[i].adsr(1.,ADSR[i].trigger);//our ADSR env is passed a constant signal of 1 to generate the transient.
