Is it going to be extended to the floating tile system so we can include it in our projects?
No. I've spend some time optimizing the FFT analyser curve so you get nicer cubic splines with the existing FFT graphs, but I don't have any plans adding this full analyser as a frontend floating tile (mainly in order to be able to change stuff without breaking client projects) - it's a analyser tailored towards the development phase.
You can get the oscilloscope displaying the waveform based on the MIDI input already by putting the analyser.oscilloscope node into a midi processing context.
