Big thanks @Balwyn. I really appreciate your help. My Synth is almost ready

Hey guys. I have a polyphonic Synthesizer. I am new to Pd. Problem is, I don't know where to put a simple LFO. If I put it in after phasor~ in note.pd, then it doesn't work, plus I have to play three notes in order to hear the fourth. Very strange! My simple LFO is in note.pd.
Thank you!
