# Hi Steven and everyone, # Once I tried to make a Scanned Synthesis program. Basically it was a two dimensional spring-mass system, where one can able to put different masses on a canvas and connect them with springs of different spring constants. # Than an algorithm will be defined for creating a wavetable. (this table will be scanned with given frequency, basically it is a wavetable oscillator) For example, N masses are put on x axis with same distance between them and are connected each other with springs. They are constraint to move only on y direction. So one can use the y coordinates of the masses as the samples of the wavetable. # The program may have different interaction modes (adding, deleting, adjusting connecting masses and pushing, moving, hitting, hammering them) So one can interactively play with the system and see the dynamics. # But I stucked at some point. I created 128 masses, and used 4-point interpolation in the wavetable, but can't get a clear sound. I thought that 128 points are not enough. But more masses makes the controlling harder. And decided that my project was useless :-) # I tried different ways to produce sound with this program. One is to use JavaSound API. This way is good to use it as standalone program. # Another way is to send the values of the wavetable to a sound synthesis program. I sent the data using OSC to Pure Data, put it in an array and played the array using [tabread4~] This scheme worked very well. Maybe better than using JavaSound API, because that API hasn't got any high level audio processing units. Writing everything yourself is hard. # Csound can use OSC too: http://www.csounds.com/manual/html/OSCNetwork.htmlSo I think someone may be interested in my half-work. I'm attaching some earlier experiment examples I've done. You have to have Java JRE to run them. This is only for you to see what the program is intended to do. # If I make a well running example which makes a connection between this program and a sound producing csound patch I'll send it to the list. # Good night! -ugur guney- On 9/6/07, Steven Yi wrote: > > Hi All, > > I saw this product "Scanned Synth Pro" today: > > http://www.humanoidsounds.co.uk/products.html > > and found that it made some nice Scanned Synthesis sounds, I'd imagine > very capable of being made in Csound as well. > > This made me think we should have a Scanned Synthesis contest or maybe > a just a monthly "let's make interesting sounds with x" topic. =) > > steven > -- > Send bugs reports to this list. > To unsubscribe, send email to csound-unsubscribe@lists.bath.ac.uk >
