[linux-audio-user] questions about useful programs

by Jakob Rohrhirsch

Hi there! I need a program to make music ;-). What i want to do is make some beats for hip-hop, so I need a drum machine, samples and stuff like that. What's your choice for that kind of usage? Thanks and greetings, Jakob

[linux-audio-user] (humourous) PROJECT PROPOSAL: Biological Sound Generator

by Carlo Capocasa

I spent a good deal of my youth battling with my guitar teacher who was constantly trying to turn me into a biological sound generator... Limiting my creativity to the exacty fashion with which I execute his instructions on how to play a Concerto Andante Furioso Con Parmigiano some dead guy wrote 10'000 years ago. (I'm sure he didn't even announce his own death). So I am now scheming a devious plan on how to a) Get back at him, and b) Demonstrate the programmability of humans to anyone who has eyes and mind to see it So my proposition: Take any instrument that is convertible to MIDI, like a keyboard, or preferably, MIDI-plug an old, whacked up rock guitar that was used by Alice Cooper to scratch his hairy buttocks. So then you get about 100 high-brow studied classical orchestra musicians (the more narrow-minded the better), hand out wireless terminals with an OSC-hacked version of Lilypond that display sheet music from MIDI signals. Have their musical teachers tell them this is one of the most avant-garde ways to peform and that it is their ticket to fame and fortune in the classical music community (believe me, these classical types will believe absolutely ANYTHING their musical authorities tell them). Then plug your flea bag MIDI scratcher and start getting your groove on. Voilà! Biological soundfont. Only downside: Latency is a bar or two. Carlo

[linux-audio-user] [Muse] ghost copies

by yves_p＠nnx.com

Hi :). Is there any way to make « ghost copies » of parts in Muse 0.7.2 pre 5 ? I mean, a copy where all modifications made on the original are reported to the copy without intervention. Also if I have a trumpet on port 1 and trombone on port 2 and if I want them to play the same thing, I just have to modify one and the other will follow. Or maybe is it possible with entire tracks and not parts ? This feature was present in the last version of Cubase I've tried, if I remember well it was version 4.0 with an Atari ST 1024 :) around 1994. I have search in the docs of Muse, clicked here and there with various shif and control combinations and search for special paste fonctions in the menus but I don't see anything like that. Thanks in advance :) Cheers, Y.

>(not to mention some > terrible humming - something else I have to look into yet...) Forgot to mention: you'd do well to get an LCD monitor if you're not alreaady using one - might be a factor in the humming problem, though lots of other things can cause this as well. -Maluvia

Hi Ken, There are lots of different ways to approach this as has been mentioned. We've struggled with it for a long time and finally achieved the levels we needed as follows: (The guitar has a Martin Thinline gold pickup.) The pickup is connected through a custom-made Zaolla silverline Y-cable (we made it using an insert cable and some adapters) into *two* Stewart UDP-1A Instrument PreAmps. This goes into a Behringer V-VerbPro Processer and from there into the hdsp9632 line-ins through the XLR analog break-out cable. (The V-Verb allows for a lot of fine adjustment on the input, output and block levels.) We've actually had a problem with too much signal on the bass end, but my husband seems to have gotten that under control now. He's getting very satisfactory recording levels now. HTH, Maluvia

[linux-audio-user] Info on recording/DSP techniques

by Tim Howard

Hello, Does anyone know where I can find a fairly exhaustive set of tutorials (or just explanations) about recording and digital signal processing techniques? I'm not very familiar with subjects such as ADT, chorus, flanger, comb filters, Bode frequency shifting, compressing and limiting, vocoding, and 101 other cool effects. For most of them, I don't know how they work, how to use them, or when to use them. You'll laugh, but I thought I had invented double tracking... :-D ...until I heard someone talking about ADT, and found out that it was invented 50 years ago! So rather than discovering everything the hard way (and the slow way), I'm hoping for a book or set of tutorials that covers these subjects. I would be very pleased if I could find a book that was centered around DSP in the Linux world... Any suggestions? Thanks in advance! -Tim

Thank you Carlo, for that delightful summary of recording/mastering processes! Definitely worth a cut & paste. :D And your 'brainstorming' ideas are intriguing.
