Hi Alec, Your memory serves you very well The procedure is exactly as you quoted above and the program works well with the KN7000 linked by USB.

It also has a facility for increasing the volume - post recording, under the 'Effects' menu option. They call it 'Amplify'. A 'Normalise' function is also included within the 'Effects' sub menu, together with quite a few additional functions.
It can also save the recording in MP3 format but requires the 'LAME' encoder to be downloaded or already present on the PC. Recordings can also be saved in 'Ogg Vorbis' format but WMA format seems to be absent.... 'suppose you can't have everything
For a free program, it is certainly quite a versatile Digital Audio Editor

that's why I've been recommending it for a long time!

not so. There is 16 bit quantisation noise; if you record very low and then normalise by 20dB for example, the noise floor will also be raised by 20 dB to the point where it is noticeable. That is why maxing as much as possible in the 7k mixer is worthwhile when recording digitally, because the normalisation required will be far less, only a few dB, and any noise boost un-noticeable. In fact it's possible to clip with edited voices at 127 without normalisation. Noise on analogue recording will be far worse, unless you have an expensive soundcard with excellent screening.

Hi Folks,

Last evening, no call it night (LOL) I have installed Audacity Freeware on my laptop and after connecting the KN7000 to the laptop and switching on I started Audacity and could set the Panasonic USB driver as input device and record the sequence directly into the tool. My solo parts were set on max (127), but to make a nice mix, you cannot set all parts at max. So some normalisation remains necessary. Neverhteless It is amazing how easy and versatile Audacity is. !

Thanks for all your input. Audacity only had one drawback yesterday: it made me see my bed around 1.30 AM at night (LOL)

Kind Regards,

Fred Mellink

maxing the balance means having the loudest parts at 127 and balancing the rest down from there as appropriate, not having every slider at 127 since that is no longer a 'balance'. Technics chose their settings to avoid clipping which is horrible in digital transfer since the dynamic range of the voices is large. The downside is some normalisation is needed, but the idea that you can produce a recording as good as a cd without any of the many technical tweaks that go into the making of a cd is rather naive.

I have been reading the postings on CD recordings and wonder why you need to go down this road as to me it seems a costly and time consuming procedure.

I have a Philips stand-alone CD Recorder/
Player which is linked to my KN7000 keyboard, PR900 Piano, Sony Mini Disk Player/Recorder, Sony Cassette Player/ Recorder. All are connected to a Technics Amplifier and all are accessed individually or together via a dedicated switch. To date, I have had no problems with recording and making my own CDs. In fact my Christmas CD was in great demand so I guess I must be doing something right.

I will say though, I have learned through trial and error that a great deal depends on the make of blank CD you are using. It is false economy to "go cheap" as without mentioning names, in my opinion there are only two manufacturers' CDs I would use and one of them in particular is excellent - the clarity of sound has to be heard to be believed.

Hmm! interesting posting this.

costly? a state of the art pc writer for £15 compared to the price of a stand alone writer, and blanks for a few pennies each compared to dedicated audio cds...

Point taken Alec, but as I am not 'au fait' with PCs for me the stand-alone was a great investment and has given me and others hours of pleasure. Each to his own though eh?

All the best.

Fred,
I went through a long hunt to find out why I ended up with glitches when recording on my laptop. I had all operating system sevices (local) turned off that weren't necessary for recording and still had problems.
The problem ended up being simple. The hard drive was too slow to keep up with the data flow simply because DMA was not enabled for the hard drive controller. Check by going to device manager and looking at "properties" of the ATA/IDE hardware controller to be sure that DMA is enabled. If running in the PIO mode, there is sure to be trouble.

I believe that DMA is enabled by default on Win XP installations - provided of course that the hard drives are capable of operating in DMA mode - as most modern drives are....
All my 'XP' PCs have DMA enabled and I have never deliberately set them up in this condition. If I remember correctly, earlier versions of Windows required the user to select DMA operation, if it was required.
