Hi, Using the code bellow. pvsbuffer and pvsbufread give very strange sounds, with lots of fft artifacts. It sounds nothing like a streigh pvs anal+synth. Is this normal behavior, or am I doing something wrong? I seem to remember that pvsbuuffer sounded like a normal resynthesis. Thanks in advance Peiman iol=2048/8 fsig1 pvsanal ain1,2048,iol,2048,1 fsig2 pvsanal ain2,2048,iol,2048,1 ibuf1,kt1 pvsbuffer fsig1, 10 ibuf2,kt2 pvsbuffer fsig2, 10 khan1 init ibuf1 ; initialise handle to buf1 khan2 init ibuf2 ; initialise handle to buf1 fsb1 pvsbufread kt1, khan1 ; read buffer fsb2 pvsbufread kt2, khan2 ; read buffer aout1 pvsynth fsb1 aout2 pvsynth fsb2 -- View this message in context: http://www.nabble.com/pvsbuffer-strange-sounding%2C-fft-artifacts-tp15859931p15859931.html Sent from the Csound - General mailing list archive at Nabble.com. |

Hello all I am a spoiled ex-(windows-asio-cubase-vst) user that had (until now) too many "instruments" to play with. I have come to understand that this "wealth" of options has nothing to do with creating music itself, and i am willing to limit my instrument choices to a minimum. Still, since i am not-much-of-an-expert in csound (yet, that is), i am currently limited to very simple instruments that (yes) they keep me interested but not excited at all. Of course, i have purchased the "csound catalog" that actually contains some nice instruments (along with some others, not so nice), however i wouldn't know if these instruments represent the cream of what one can do with csound or if they are "mediocre" by today's standards. Surely, i have listened to some extremely exciting instruments in the (long gone?) csound radio page - nothing in the catalog comes close. So, the question is forged: what is the easiest and what is the best approach for creating csound instruments? Please share your experience. Regards Panos |

Hi! Had a look at http://www.csounds.com yet? they also have a collection of instruments. I know, that there are some nice once. But if you're in need of some natural instruments, csound alone might not be the only way you want to go. If you use linux, have a look at linuxsampler http://www.linuxsampler.org It reads gigastudio 2 samples. And probably take a look at fluidsynth http://www.fluidsynth.org It reads soundfonts. That way you might be able to use some of your old libraries. Another look for the linux-side of things might be: http://linux-sound.org or http://www.linuxaudio.org these sites list linux-apps and linux-sound.org also has a section on csound-material, which might be helpful.

I don't know if there is a straightforward answer to this question. To each their own. I think a nice way to learn Csound and develop some nice instruments is by learning about different synthesis techniques and then trying to implement instruments around them. I can't tell you how much I learned from creating Csound instrument from the flow charts in the Dodge-Jerse book, it's really a lot of fun to do even though so many people have published their version of the instruments in Csound already. One other thing which I see all the time with my students is that they rarely ever exploit the full timbral capabilities of their instruments. Usually if I build a simple instrument I will use p-files for almost every parameters. Then I will go to the score and experiments with each different p-field value. If I like a sound or timbre from one particular score statement I will comment it out later use and then move on and try to see if I can get more interesting and different sounds using another combination of p-field parameters. Even with only a few oscillators and a different function tables you should be able to create all sorts of interesting and wonderful sounds.

The most helpful hint in the beginning was to me, that csound's orchestra files, are nothing but: output1, output2,... module_name input_p1, input_p2,... Thus came the knowledge, that csound is just really a "simple" modular synthesizer. Reminds me of something like "Doepfer a100" or other old analogue modular systems. That is the easy part. The dificult one was understanding some of the more sophisticated synthesis techniques. I still don't really manage. :-( Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de |

Hello Panos, It is great that you are getting into Csound and I would say that a universe of unimagined sound awaits you. For me, the path of growth with creating Csound instruments is one of constantly expanding and refining a core set of instruments. If you were to keep adding features to the instruments that are currently "keeping your interest" you might find that you have created some very versatile and amazing sounding instruments that are uniquely you. Your imagination and creativity in this are your only limitations. Try anything no matter how incorrect it might sound. Combine two instruments, make the mix of them variable according to pfields in the score. Create ten copies of these within the same instrument... give each a different amplitude envelope, also variable within the score... give each a different frequency relationship to the others variable by a multiplier... the list is endless. In other words keep experimenting until something inspires you. Further, it is my opinion that the compositional process begins with the creation of the instruments. So for each new project I add to and rearrange this set of instruments that have been years in development. I throw our certain aspects of them and create new aspects. I think that creating interesting Csound instruments is a life-long pursuit. IMHO the score is as important to how your instruments sound as the instruments themselves. The way the sounds overlap, the frequency relationship and harmonics thereof... the placement in time and space... all simple examples of creativity. I once saw an amazing drummer at a percussion seminar. We in the audience were anxiously awaiting his performance. We imagined a huge drum set with 30 drums and 15 cymbals etc... Instead, he came on stage with several tin cans of various sizes and proceeded to give us one of the best percussion demonstrations I have ever seen. He blew us all away. It is not the size of the wand but the magic of the magician that counts. The simplest of Csound instruments can become part of an incredible composition. It is how you use them that matters. I hope this is of some assistance and good luck, Michael Rhoades www.perceptionfactory.com On 3/6/08 3:49 AM, "Panos Katergiathis" |

In case someone's interested, I worked out what's going on. It's because ktime is k-rate the time resolution depends on the csd control rate.
