[LAU] Steinway_IMIS2.2 soundfont (no loops fix)

by Roberto Gordo Saez

This is Steinway_IMIS soundfont, version 2.2. ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2 This version fixes the issue with loops. I hope this is the good one and there are no more remaining major bugs. Marcos is a little busy right now, so he asked me to make this fix. He is thinking to make other improvements, so expect more updates soon.

[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

[LAU] Looking for a mixer, 16+ channels

by hollunder＠gmx.at

Hi guys (and gals), a good friend of mine is in the market for a mixer that is at least capable of recording a whole band simultaneously. He thinks that 16 channels might be a minimum for that, but he isn't exactly experienced, and me neither. It would be nice if it would work as firewire audio interface as well, like the mackie onyx mixers, mainly because it might mean less trouble overall. Those onyx mixers look nice, and are supported by ffado, but we'd like to have some more options. Linux support isn't a strict requirement but it would be really nice to have as option. So far it didn't work for him, but when the hardware works with linux I can show him what's there and what's new from time to time. In this case he has a budget of up to 3000 Euros or possibly more, but the stuff really needs to work for a studio. Thanks in advance for any advice, best regards Philipp

[LAU] First release of jkmeter

by Fons Adriaensen

Hello all, The first release of jkmeter is now available in the usual place: <www.kokkizinita.net/linuxaudio/downloads> Also updates of japa and jnoise (mostly maintenance, but see also below). >From the README: jkmeter-0.1.0 (03/08/2008) -------------------------- Jkmeter is a horizontal or vertical bargraph level meter based on the ideas of mastering guru Bob Katz. See <http://www.digido.com/bob-katz/index.php> and follow the links on 'level practices'. This is the type of meter you want for live recording, mixing and mastering. It probably makes no sense to use it on all tracks of a DAW, where keeping digital level within limits is the main purpose of metering. This release implements the K-20 meter. Future releases will include the K-14 meter as well. A K-meter displays both the true RMS level and the digital peak level. The ballistics as defined by Bob Katz are somewhat ambiguous. In this implementation the RMS meter is about 15% faster than an VU, but without the overshoot. This provides a good indication of subjective loudness. Instead of providing extra gain for the RMS level, the K-meter displays it on the same scale as the digital peak level, but puts the '0dB' mark and the color change well below the OdB full scale level. For the K-20 meter it is 20dB down, for the K-14 this is (surprise !) 14 dB. To use the meter as envisaged by Bob Katz, you should have a fixed monitoring level, adjusted so that pink noise indicating 0dB on the meter corresponds to 83 dB(C) (from each speaker) as indicated by an sound level meter. Note the (C) - not (A) - weighting. As of release 0.4.0, both japa and jnoise provide a pink noise source at exactly this level. The current release does not include the 22kHz lowpass filter required for frequencies such as 96kHz and higher. Enjoy ! -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia O tu, che porte, correndo si ? E guerra e morte !

Re: [LAU] E-Mu ESI4000 SMDI

by Dan Richert

I'm using an Adaptec AHA-7850 SCSI interface card. I used this in the past with Sound Forge (back when it was made by Sonic Foundry) and it worked fine. I think SMDITools' problem with the ESI4000 is sample numbering. I believe SMDITools starts at 0 where the ESI4000 starts at 1 (0 is the clipboard). I'll come back with more info when I get another chance to dig around in the SMDITools code (my C is far from great though (far from good, even)). Thanks, Dan Gordon J. C.

Re: [LAU] Hardware: elektr piano / keyboard

It was the keyboard version of the MC-505 Groovebox in fact. Initially, I started off as a guitarist and just wanted to have a keyboard/synth to play some accompaniments to my guitar noodling. Today I play more keyboard then guitar, also for other reasons. I have tried/played some diff. keyboards/controllers, like i.e. the M-Audio Keystation Pro 88 (favoring a controller/softsynth approach), some of the better Roland/Yamaha Stagepianos, the Yamaha CP-series and then some... I personally most often preferred the Roland keys in the lower pricerange, the Yamaha keys win in the upper pricerange IMHO. The CP series i.e. are all high quality, keys and soundwise. But then these are all outta your pricerange I guess, unless you'll find some 2nd hand top offer. > I think you speak some right words.. Have you experience with playing > elektr. piano/ keyboards? > Polyphony is the max playable number of notes that can be played at any one time. So, if you're playing a simple C chord, you'll use up 3 voices of polyphony (C - E - G). But if now you keep them ringing with the sustain pedal to play some single notes over your chord, you stack up the voices. Since Piano/E-Piano playing very much involves your sustain pedal, it quickly builds up to way more then 32 voices. > Where do you use polyphony for?

[LAU] : Cracking sounds

by Mysth-R

Hi, I've got a strange behaviour with my midi controller and/or freebob/ffado. I made a pure data patch, with a midi learn function. So I can control everything with my midi controller. When I use jack with Freebob or ffado (I tested both) and a Presonus Firebox, I got cracking sounds every time I move faders, pots from my Midi Controler. When I use jack with alsa and a poor usb berhinger UCA202 it works perfectly : no cracking sounds I am running Gentoo, with a rt kernel. I configured the rtirq script. I tested it on a opensuse with rt kernel too, and it does the same. Could someone test my patch and tell me if he got cracks ? with firewire ? with alsa ? You will need at least pd-0.40 or more. Some externals, they are not necessary to hear sounds (bbogart (for popup), sigpack~, zexy, iemlib). The patch contain * 3 live loopers with effects * Master to set tempo, general volume, general pitch, and rooting + a preset/bank system. * a sub-patch with a DrumStation * a sub-patch with a small synth (TriOsc) To test rapidly you just have to click on the load bank button (on the bottom-left corner), and you should hear sounds from the TriOsc synth Then you can assign control clicking the green led under each control. The red one is to forget the assignement. here is the patch : http://mysthr.free.fr/Documents/LiverLooper-0.6.tar Thank you very much ! kind regards, Mysth-R -- * *************************************************************************************** * {^_^} Mysth-R {^_^} * <= Aide Auditive => * * http://myspace.com/mysthr * http://myspace.com/aideauditive * http://mysthr.free.fr/Joomla => Site dédié à l'audio sous Fedora/PlanetCCRMA. * ***************************************************************************************

[LAU] Usage of undefinded MIDI mesages

by Crypto

Hi, I have turned an old analogue electric organ into a MIDI controller. All the old push buttons, switches, pots, drawbars can now trigger MIDI events. Because I would like to make the MIDI messages static (i.e. they are linked with particular buttons and faders and will not be changed) I have thought of using an external application (keykit in this case) to work on incoming MIDI events of the MIDI controller, filter them and trigger newly defined MIDI events with it. I would like to make the MIDI messages transmitted by the controller as short as possible. I have thought of assigning the Bx (Control Change) command to the buttons and faders, but this would mix with/overwrite other control change commands sent by other MIDI devices. It has to be possible to distinguish between the buttons/faders by the MIDI message that each one triggers. How about the System Common Message F4 and F5 which are not yet defined in the MIDI standard? Could I add some extra data bytes to identify the type (button or fader), the number and value? Like this: F4 125 70 (Fader 125 sends value 70) keykit would recognize this fader and set volume level for channel 2 for fluidsynth. Or, in another situation, increase sustain value for channel 3 for fluidsynth. or: F5 10 1 (Button 10 sends value ON) keykit would recognize the button and turn on sustain for channel 1. Thanks for any hint and kind regards, Crypto.

[LAU] Convert PDF to MIDI?

by Christopher Stamper

I'm looking for a free way to convert my PDF scores to MIDI files, to save the work of manual entry. I think it can be done in Finale (convert pdf to tiff first), but that doesn't help me any. Is it possible? -- Christopher Stamper Email: christopherstamper(a)gmail.com Web: http://tinyurl.com/2ooncg gTalk: http://tinyurl.com/6e359r Skype: cdstamper

I finally found the time to look at it... It is probably one of the best rt-audio tutorials I have seen... Picture that: a guy actually takes the time to make *video* for the *linux journal* to tell you to change the RT prio of.... QJACKCTL ! I hope I misunderstood... Really... And what's all this about set_rlimits ? There's PAM for that (well, except maybe on slackware where they... don't like PAM) Oh, a good one too : "As is usually the case with Linux, the first thing we need to do is recompile the kernel". Dude... this is 2008... We have audio distros out there... Seriously, who's that guy ? -- Marc-Olivier Barre -- --- MarcO'Chapeau ---- - www.marcochapeau.org -
