preferences clavinova using midi cables

OK, I just did a test and you can't hear any surrounding noise anymore. That's good news. But there's a soft and very high but disturbing electrical zzz-like noise. Any idea what that could be ?

Hi Gale
Yes, the jacks that go into those AUX have a red and white band. They're like the picture I uploaded to this message. And they go directly into the mic entrance.
So I should use a USB-adapter like the UCA-202 to have a better sound ?

Un-necessary amplification because you are connecting to the wrong type of port? Did you get a stereo result where the Audacity left-hand playback meter dances differently to the right-hand meter?

Perhaps you could post a sample of the zzz-noise.

Gale, I'm attaching the zzz noise to this message, hope it works.
The piano I recorded sounds stereo and there is a difference between the left hand and right hand meter, when not playing and only having the noise. You need your head phones to hear it really well.

That's your computer and maybe some lesser shielded cables.

A decent USB interface would probably solve that. It might pick up other noise, depending on your computer. Some laptops are not suited for audio, I'm afraid. But if you buy from a shop that lets you return stuff, you can test without too much hassle.

Besides the already mentioned UCA202, the UMC202HD is only 50$ now, direct from Behringer:

If you'd ever wanted to sing and record, it has 2 "Midas-like" microphone preamps.

Hi Gale
Yes, I also want to sing and add rythm-like sounds (rythmical scratchings on things). Behringer still best option ?

[Gale Andrews]

Your recording of the piano was stereo, so you have one of the "compatible" mic inputs that can accept line level.

You can get rid of a lot of the noise with Audacity's Noise Reduction without significantly harming the piano.

I agree with cyrano the UMC 202 HD seems a good bet - you could record keyboard and voice at the same time with that. You might get a different sort of whine or crackly noise with that, but probably a little lower than the current noise with the mic input, and the quality would be better.

It's only 2 channels, so recording microphone and keyboards in stereo simultaneously wouldn't be possible.

But you could first record keyboard in stereo, play that back and sing along.

If you need to record the keyboard in stereo and simultaneously record the microphone, you'd need a 4 channel interface, like the UCM404 or UCM404 HD

True, of course. But you could use the Audio Track Dropdown menu to Split Stereo to Mono, then use the L....R pan slider on each track to adjust their positions in the stereo field.

Those are convenient shortcuts. There's always the actual mixer option. The small mixer shown will mix four microphones and one stereo instrument (or combinations) into a stereo show. Digitize and record. The down side there is no ability to take it apart and remix it later.



This mixer is no longer available, but the Behringer 802 is still a current product and will do similar tricks.

Both mixers have analog outputs and need a digitizer for recording in Audacity.

If the UCA202 is used for digitizing, either setup can be used in perfect overdubbing; listen to yourself in real time and the recorded bed and rhythm tracks.
