Hi,

 

I elextended a bit the scanned synthesis sandbox example and I added it to CsoundQt Examples/Synths.

 

In git:

https://github.com/CsoundQt/CsoundQt/blob/develop/examples/Synths/Scanned_Syntehesis_Sandbox.csd

 

The spring matrix (circularstring-128) is embenned in the file (encrypted with csb64enc and included with <CsFileB> tags. Very useful not to let your included thing get lost! Never had experience with that before.

 

 

I added a button and spinbox for choosing and playing the preset, support for MIDI keyboard (you can use also the virtual midi keyboard) to play crazy scanned synth music, a graph for showing the tables used and FFT output of the sound.

 

It is a lot of fun already and you can go much further from here studying the code, Live Event sheets for parameter combinations, creating new tables for various parameters and so on.

 

I hope to do a small demo, too, later...

Thanks a lot Tarmo, very useful. I'm having a lot of fun.

Try kdamp=-0.7 that gives a lot of string like sounds, preset 1 sounds guitarrish, 6 pianoish etc

One thing that would be useful, is having a visualization of the spring model vibrating, maybe an easy way to do it is to use scanu at audio rate. I tried doing that and outputting to channel 3, but it didn't quite work. (I'm still very new to csound/csoundqt)

Hi,

thanks, Iain, indeed I mistyped, corrected then the filename and correct link is

https://github.com/CsoundQt/CsoundQt/blob/develop/examples/Synths/Scanned_Synthesis_Sandbox.csd

Gerard, I am afraid that the actual vibration of the spring is so complex, you would not make much out of  it -  every mass has (or can have) different weight, every spring different stiffness, they all are connected in different ways and there are so much more parameters. And don't forget, its not sound of the vibrating spring, but the moving virtual body is "scanned" - read using a certain trajectory with certain speed.

Very intresting theory indeed. I think most of the sounds tend to bee a bit harsh and need some more processing (different filters etc) but to have a system that creates live, dynamic oscillation, is just great.

I uploaded a small impro on MIDI keyboard with the Sandbox example to:
https://soundcloud.com/tarmojohannes/csound-scanned-synthesis-demo

It could be used musically in much more interesting ways, of course.

Best!

Sure the way I'm proposing would only be useful if each mass is only connected to the next one, like the circular spring, and if the scan trajectory is the normal mass by mass one.

A more advanced visualization would be required for anything else, but I think it could still be useful or at least visually appealing :P.

See this program https://www.youtube.com/watch?v=NHeCjPS3Ofw&nohtml5=False

It's a 2d system with very complex vibrations but it still gives a little insight on how the sound is produced.  Here's the paper https://www.dafx12.york.ac.uk/papers/dafx12_submission_18.pdf
