Hello

I managed to make my example plugin (based on the only LV2 synth tutorial that I could find) monophonic :)
Now the only think that is left is a portamento function, to go from one note to another (exactly like so-404 does).

I guess it has to do with the

  void on(unsigned char key, unsigned char velocity) {
    m_key = key;
    m_period = m_rate * 4.0 / LV2::key2hz(m_key);
    m_envelope = velocity / 128.0;
  }

  void off(unsigned char velocity) {
    m_key = LV2::INVALID_KEY;
  }

functions, I need to store the "note out" value to go from that, to a "note in"...

Does anyone know the algorithm to implement that? That would really help me.

Thanks

PS - Excuse my poor English, I'm working on it
