Newbie here..
I'm using the sketch for frequency energy supplied in Processing and i want to use the 3 outputs of that (kick,share,hat) to trigger pins on the arduino. I have successfully communicated with the arduino using processing with the arduino_out sketch but am having trouble modifying the frequency energy code to output to the arduino. Any ideas?
Heres the supplied code:
/**
- Frequency Energy
- by Damien Di Fede.
- This sketch demonstrates how to use the BeatDetect object in FREQ_ENERGY mode.
- You can use
isKick,isSnare, isHat,isRange, andisOnset(int)to track whatever kind- of beats you are looking to track, they will report true or false based on
- the state of the analysis. To "tick" the analysis you must call
detect- with successive buffers of audio. You can do this inside of
draw,- but you are likely to miss some audio buffers if you do this. The sketch implements
- an
AudioListenercalledBeatListenerso that it can calldetecton every buffer of audio processed by the system without repeating- a buffer or missing one.
- This sketch plays an entire song so it may be a little slow to load.

// a beat detection object that is FREQ_ENERGY mode that
// expects buffers the length of song's buffer size
// and samples captured at songs's sample rate
beat = new BeatDetect(song.bufferSize(), song.sampleRate());
// set the sensitivity to 300 milliseconds
// After a beat has been detected, the algorithm will wait for 300 milliseconds
// before allowing another beat to be reported. You can use this to dampen the
// algorithm if it is giving too many false-positives. The default value is 10,
// which is essentially no damping. If you try to set the sensitivity to a negative value,
// an error will be reported and it will be set to 10 instead.
