It's possible they use the USB to transport the MIDI Highly likely, though I've not been able to look at a manual either. Does the instrument have a place to connect headphones? If the piano has "AUX Out" or "Line Out" connections that would be even better, assuming that you are...

(setq freq (min (max freq 10) (/ *sound-srate* 2.0))) will constrain the frequency value between 10 Hz and the Nyquist frequency, but perhaps it would be preferable to raise an error message? Perhaps something like: ;control freq "frequencyt" real "" 50 10 10000 ;control q "...

Step 1 - Import WMA file.
Step 2 - Export MP3 File.

What exactly are you wanting to do, with which version of Audacity, on what sort of computer, and why?

You've been to the Windows Control Panel?
You've enabled "show disconnected/disabled devices"?
What recording devices are shown in the control panel?

Personally I'd prefer a default of 50 Hz

I really like the plain and simple approach, but...
there needs to be some error checking;

Generate or import a track with a 8 kHz sample rate and apply a notch filter with a centre frequency of 5000 Hz and you'll see what I mean.

If "DC off-set correction" is required, that should be first. Noise reduction should be done before anything that changes the relative levels of different parts of the recording (when you adjust the level of a section of a track, it will also adjust the noise level, but noise removal is mu...

16 bit? 24 bit? 32 bit? 32 bit float?
Converting any of these will have minimal loss, but if you want zero loss then you need to state the details.

Shows me this message for sine: Nyquist Did not return audio Not sure why that is - I'll look into that. What it should do is to "push" the sine wave shape to one side or the other in similar fashion to what happens with the triangle wave. I already noticed the difference in square wave. ...

Yes. (except for "minimum Q is 0.01" which is far too low for any practical application that I can think of.) 50/60 Hz presets can be useful, though I'm open to suggestions of what Q to use for these. Q > 1 affects a more narrow band but can cause ringing. A single notch filter can be a co...
