Could not open or find file (rawwaves)
Hello Ahbee, i'm currently looking into your example_simple as I want to use ofxStk in my project. Upon starting, I am receiving a Fileread::open Error:
I have the files set up just as I downloaded them:
Can you tell me, if theres something missing? Thanks in advance, Elli
Is this just from trying to run "example_simple"? What version of openframeworks are you on? i see some ios stuff are you trying to make it run in ios?
if you are on ios you have to call stk::Stk::setRawwavePath(ofToDataPath("rawwaves")) before making any calls to stk. in the "example_simple" there is a member stk::BeeThree synth that uses the 'rawwaves' in its constructor. That is probably what is crashing your program. So just make any stk members a shared_ptr, like std::shared_ptr<stk::BeeThree> synth
in the setup if you do
stk::Stk::setRawwavePath(ofToDataPath("rawwaves"));
synth = std::make_shared<stk::BeeThree>();
it should work fine.
i'm using version 0.9.8 release. yes, i would like to use it for ios. I added both lines you mentioned above, but it still gives me the same error. Will try it further and get back to you later. Thanks.
and yes, i have this problem running the "example_simple". Could it have to do with the version of of?
It works for me on ios. Can you create a new ios project with project generator while selecting ofxStk as an addon Next copy the "rawwaves" folder into "bin/data" then paste the follwing code for ofApp.h and ofApp.mm
ofApp.h:
#pragma once
#include "ofxiOS.h"
#include "ofxStk.h"
class ofApp : public ofxiOSApp {
public:
void setup();
void update();
void draw();
void exit();
void touchDown(ofTouchEventArgs & touch);
void touchMoved(ofTouchEventArgs & touch);
void touchUp(ofTouchEventArgs & touch);
void touchDoubleTap(ofTouchEventArgs & touch);
void touchCancelled(ofTouchEventArgs & touch);
void lostFocus();
void gotFocus();
void gotMemoryWarning();
void deviceOrientationChanged(int newOrientation);
void audioOut(float *output,int bufferSize,int nChannnels);
std::shared_ptr<stk::BeeThree> synth;
};
ofApp.mm
#include "ofApp.h"
const float NoteC = 65.41;
const int op4FeedbackCC = 2;
const int op3GainCC = 4;
const int LFOSpeedCC = 11;
const int LFODepthCC = 1;
//--------------------------------------------------------------
void ofApp::setup(){
stk::Stk::setRawwavePath(ofToDataPath("rawwaves"));
stk::Stk::setSampleRate(44100.0);
synth = std::make_shared<stk::BeeThree>();
ofSoundStreamSetup(2, 0);
}
//--------------------------------------------------------------
void ofApp::update(){
synth->controlChange(op4FeedbackCC, 60);
synth->controlChange(op3GainCC, 60);
synth->controlChange(LFOSpeedCC, 0);
synth->controlChange(LFODepthCC,0);
}
//--------------------------------------------------------------
void ofApp::draw(){
}
//--------------------------------------------------------------
void ofApp::exit(){
}
//--------------------------------------------------------------
void ofApp::touchDown(ofTouchEventArgs & touch){
float amplitude = .5;
synth->noteOn(NoteC, amplitude);
}
//--------------------------------------------------------------
void ofApp::touchMoved(ofTouchEventArgs & touch){
}
//--------------------------------------------------------------
void ofApp::touchUp(ofTouchEventArgs & touch){
synth->noteOff(.5);
}
//--------------------------------------------------------------
void ofApp::touchDoubleTap(ofTouchEventArgs & touch){
}
//--------------------------------------------------------------
void ofApp::touchCancelled(ofTouchEventArgs & touch){
}
//--------------------------------------------------------------
void ofApp::lostFocus(){
}
//--------------------------------------------------------------
void ofApp::gotFocus(){
}
//--------------------------------------------------------------
void ofApp::gotMemoryWarning(){
}
//--------------------------------------------------------------
void ofApp::deviceOrientationChanged(int newOrientation){
}
void ofApp::audioOut(float *output, int bufferSize, int nChannnels){
stk::StkFrames synthFrames(bufferSize,1);
synth->tick(synthFrames);
for (int i = 0; i < bufferSize; i++) {
output[2*i] = synthFrames(i,0);
output[2*i+1] = synthFrames(i,0);
}
}
This should just play a note on touch down.
