I've ditched the usual header for the moment, I think it doesn't help much anyhow.

Techno, by John Scofield (see here a youtube version). I played this in the Jazz combo of Delft University years ago, great song.

I compiled LinuxSampler which can read GigaSampler files.

   wav   piano new SF in QSynth (fluidsynth), guitar Gigassampler played combined as (Usb) midi layer

Another One Bites the Dust rendered with a S90, digitized with a Lexicon Omaga 24 bit AD converter, based on a internet found MIDI file of the song, played over Usb-midi from a fast notebook running Fedora 8 (dual core) with Rosegarden as sequencer and 32 bit floating point audio recorder and (5 stereo track in this case) mixer and Ladspa effect plugin provider. I sang a voice track with a AT2020 microphone preamped by the lexicon and processed by equalizer, compressor and 2 reverb plugins, and I made a submaster compress the combined synthesizer sounds, which themselves were compressed and processed with the excellen S90 effects, and the voice result, and I mixed an extra channel of bass sound bypassing all effects. To finish the sound I added another effect on the voice chain which is the Jamin multiband compressor/32 band equalizer of which I mixed varying amounts on the submaster with the processed singing. All that was done in a couple of hours, including setting some of the machines/software up, and mixed mainly on my large system, so it primarily was a mix to sound good at some volume and with powerfull transparency being availble and loads of unhyped bass-end, but I also listened via the medium sized biamped monitors, even smaller speakers, and even on a mobile phone, and it all sounds great. I made a version postprocessed by Jamin to do some sublow filtering for the poor smaller hifis and multi-band compression to try out making the intelligibility better, even though I don't like a major FFT on over the whole signal, but anyhow I tried and here it all is:

   wav file (CD quality, 31 MB) main version
   wav file (CD quality, 30 MB) mix + yamin overall multicompression/some sublow filtered out
   mp3  (320kb/s, 7MB) main version
   mp3  (320kb/s, 7MB) extra jamin version
   mp3  (48kb/s  , 1 MB) main version
   mp3  (48kb/s  , 1 MB) extra jamin version

As usual the small mpegs are fairly worthless, but these can be listened to, even immedeately on a 56k6 modem, the 320s are bearable, but the 16 bits 44.1 stereos are cool.

A pro like rendering of Funky Town, all sound coming from the S90, which however has been quite differently programmed with sounds and effects than the original midi file from the internet. I don't know if those files are all legal, let's hope so and that the original karaoke and such don't suffer more income than already with all that new age pooh being mistaken for music. No extra effects in the computer, only the Lexicon AD converted S90 output, straight:

   wav file  (CD quality, 57MB)
   mp3  (320kb/s, 13MB) main version
   mp3  (128kb/s, 5MB) extra jamin version

The above is a screendump from maybe a year ago, it is probably from a HD video (more like film) quality assesment/improvement session. Normally one would look for high fidelity for instance on some monitor screen, but as os clearly visible, high fidelity isn´t really the thing with the controls so far of as is visible from the sliders. If I recall correctly the scene was also highly artificial, the lighting improvised and certainly not to look natural. Maybe some is lost from because of the jpeg, but also with HD footage: what isn´t in the recording cannot be processed in unless one lies or simply paints a picture, which is not a practice I engage in. Posing (as it is) is fine of course, it´s drawing and distorting the image I´m talking about.

I´ve understood, for instance from the (***) open source film that drawing in film frames in spite even of good quality 3D graphics is probably quite often done, which I don´t agree with much or ever take part in: my movies are filmed or 3D generated, and processed with algorithmic means, but never drawn in, IIRC never even, maybe not counting one time when I was trying out a tablet I can use, which was fun, but more a drawing, not a film although it technically was. Oh, and it was fun that that was done one the beamer, not a screen. Judging from the size of the above screen dump (1200x1920 pixels) this was done on a machine where the HD could be blown up to actual pixel per pixel screen coverage of the full HD frames, which is cool.
