I'm working on a piece, for which, in a section, I'd like to do a "glissando" with random notes in a restrained "space", I mean, starting from an A point that has X random "space" and make a "glissando" of that "space". I solved it like this: knum1 linseg p5, p3, p6 knum2 linseg p7, p3, p8 knot random knum1, knum2 p5-p8 are the notes I choose in the score, for which, to make that effect, p6/p8 is 4-5 semitones away from p5/p7. Now, the problem is that notes are, many times, repeated in succession, which doesn't make it really sound that "random". So what I should do is make knum2(A) ≠ knum1(A). I've been thinking of a proper syntax, but haven't really found a good one that works the way I want, mostly where I should be writing it (I mean, in the instrument itself). I know it may be an easy thing to solve, but as I've never really done it, I'm not so sure. If someone could help me out with this, I'd be really thankful! Thanks very much and happy new year!

Andrea, Thanks very much! Didn't know about the dust opcode! I'll try it right away. Silly question: what would "iciao" respond to? As I noticed you put it as a "p" and I guessed it's something specific for the general code and not specifically for the dust opcode On Tue, Jan 2, 2018 at 4:15 PM, Andrea Strappa <a_strappa@tin.it> wrote:

I used 'iciao' only to fill an empty pfield, you can remove it. Ciao Andrea Il 02/01/2018 16:27, Santiago Bogacz ha

Dear Andrea, From a long time ago... you posted this excellent and clear and inspiring little instrument to the Csound mailing list. - I look forward to sharing it with my students this semester. Funny. I always think of "listening" to dust and not using it as a random trigger source. - this is why I loved Csound so much. Great people like you change the way we understand or think of imagine. Super appreciate. -Richard Dr. Richard Boulanger Professor of Electronic Production and Design Berklee College of Music Professional Writing and Music Technology Division On Tue, Jan 2, 2018 at 10:15 AM Andrea Strappa <a_strappa@tin.it> wrote:
