Good vibration

Hi all,


My actual goal is extremely simple : i'm currently searching an opcode, or an entire instrument, to play during a while (e.g. 10 or more secunds) a very pure and stable sound (like strings or this kind), and that all in polyphony mode, i mean e.g. 3, 4, 5 notes as usual.

To be easier to understand, i tried namely the known DeepNote.csd (essentially vco2) and searched how to use it for my goal. Natively, DeepNote.csd sounds great, but it has 30 notes. I reduced that to only 15, sounds again good. I reduced again, becoming only 3 notes : in this case, the sound is relatively similar, here isn't the problem, but with amplitude sinusoidal variations. What happens ? Nyquist question ?

I made also several tries with simples opcodes, oscil, vco, buzz : with only one note, allright ; with 2, 3, more, again the amplitude (the volume, finally) isn't stable for a long time (10 secunds), it is a bit sinusoidal.

It's clearly a kind of newbie problem, maybe the use of filter opcodes can solve that, but for the moment i fund nothing sufficient to obtain a very pure polyphony sound during a good while.

I'm not fully sure that my explanation is clearly understandable, but if someone can help me in this way...


Cheers,

Sergio

What is DeepNote.csd, and where do you get it ?

Hi all,


New idea i become about the problem explained here on top : could it be latency related ? I mean, could the installation of a real-time kernel (I'm on Debian) help me, or probably that will have no big interest ?


Cheers,

Sergio
