Ok but use that to paste the code itself, not the link to it! Better to keep things in this thread than having to rely on external services, things can easily get lost.
So future users will still be able to read this conversation for learning!
Btw the link above works now
ok Looks like I managed to get it preformatted. ok I learned but, except that if I paste the code I get a very long response if itās not a problem Iāll post the codes directly 
Thanks very much for the help
No worries, itās important to understand if there are issues on the forum itself since itās still relatively young. So feel free to ask if you have any doubt or issue.
If your code is very long you could also use the two things in combination, so preformatted text inside a summary
instr 1
kamp = .6
kcps = 440
ifn = p4
asig oscil kamp, kcps, ifn
outs asig,asig
endin
instr 2
kamp = .6
kcps = 440
ifn = p4
asig oscili kamp, kcps, ifn
outs asig,asig
endin
Hi again Mau, I was able to download the file this time. Can you be more specific on what you want to change or achieve? Apologies, I guess Iām just not exactly sure.
what I want to achieve is the same exercise as instr 1 to 7 but with the option to filter the signal for each group of frequencies that glide. instr 8 must play starting from a triangular wave sound and then descend after the freq of 1000, 2000 up to 4000hz in a sawtooth wave through a filter.
same in concept as your example of application of the freq. of 200hz which changes from sawtooth to square wave in 3 or 5 seconds.
Which would be the basic exercise of instr 18! I hope that with the translator it can be clear Thanks for All
Hello to you St Music. I also sent you a private message about what I hope to achieve is easier to understand.
Thanks, Iām waiting for your news
Hi, sorry for the delay. I donāt see the private message for some reason, maybe Iām not looking correctly? You can try sending again or post here and Iāll try to help you figure things out.
One thing I noticed you mentioned if I understand correctly - you want to go up in pitch as a triangle then down as a saw filtering to square? Perhaps others might have a better suggestion but I donāt know how to properly filter from a triangle to a saw, seems tricky.
I can think of other ways to do that, such as morphing or interpolating between the tables but Iāll wait to hear from you before I make any suggestions. Talk soonš
@maupetrucci if you want you can send me a message in Italian with your idea and I can try to translate it. I cannot help with the Csound code at the moment as I am super busy, but I can probably translate it in English better than an automatic translator, those sometimes can fail (or be imprecise) with technical stuff.
hi st. No let me explain . in instr 8 I should do the same thing as instr 18 (which is the example of the subtractive synthesis that you carried out) but using the frequencies that I chose as you can see on the last file you downloaded on instr 8.
So I have a glissado that it starts from a sawtooth wave and ends with a square wave through subtraction for each kfreqinviluppo e onwards such as kfreqinviluppo2, kfreqinviluppo3 etcā¦
Example: fkreqinviluppo from 50hz to 400hz sawtooth wave then at 1000hz it starts to change to square and go down to 50hz again. Thanks, I hope itās very clear now
Ok, I think I get it now. The issue here with instr 8 is you have 4 oscils, each with seperate output names, but you have 20 filters many which share the same name which I donāt think will work. I think thatās why you are getting odd results.
There are a few ways around this. One would be to rename them aflt1 thru aflt 20, then to add them all together as you have done on line 103 (aquadra).
Another would be to have one oscil & 5 filters in instr 8. Then to modify the 4 envelopes:
kfreqinviluppo linseg p6, p3/5, p7, p3/5, p8 , p3/5, p9, p3/5, p10, p3/5, p11, p3/5, p12
You could then use 4 score entries:
i8 80 30 .5 3 50 100 400 1000 400 100 50
I8 . . . . 2000 500 200 and so on
And finally, but a little more advanced, you could probably create something called an UDO which would simplify the code. I need to give it some more thought unless someone here has a better idea.
Iāll try to look at this again later tonight. Itās not meant as a criticism but sometimes itās hard for me to understand the intent of another personās code, Iām not a very experienced user. And there are some small problems I see, for example with:
kfreqinviluppo linseg 50, p3/5, 100, p3/5, 400 , p3/5, 1000, p3/5, 400, p3/5, 100, p3/5, 50
you use p3/5 but get are 7 different frequencies. So it will never reach the final one (50).
Just to be sure - with instr 8 do you want all 4 oscil to be playing at the same time, added together? Or do you want to achieve something like at the start of the score using instr 1 - 7?
hello st :-).
So the idea is to make them play starting when the previous wave reaches its maximum frequency, the 2nd wave must start, etc.
Obviously I would like there to be no distortion. In order not to distort each subsequent oscili it must begin with a crescendo envelope and the release with a slight fade out.
However, on this I would also like your advice on what is the best solution to make each subsequent oscili heard (which starts at the maximum freq of the previous one )without creating too much chaos.
Thank you so much you are a genius
Ps. My example :slight_smile ;

hi st music I added another instrument. Everything seems ok to me but it doesnāt work in patches itās a simple fixed spectrum additive synthesis.
Function 1 refers to sine which is what I need. but it doesnāt sound like everything. Ps have you already viewed the previous exercise in the post?
Thank you infinitely

Hi Mau. I still need to answer the previous question, itās a little more involved so need to think of the easiest, cleanest solution. Will try to look at it later tonight.
Iām not sure about your newest question. First of all 50 Hz is a very low frequency for a sine wave so itās difficult to hear. It might be better to start with a higher base frequency. And Iām not sure why you chose certain frequency ratios like ifreq * 1.2. Are you deliberately looking to add inharmonic frequencies?
Hereās an example that would use additive synthesis to create a simple saw, similiar to what you did before:
giSine = ftgen(1, 0, 4096, 10, 1)
instr 9 ;Additiva Spettro Fisso
iamp = p4 ;ampiezza
ifreq = p5 ;frequenza base
a9 poscil iamp * 4, ifreq, 1 ;freq fondamentale

a11 poscil iamp * 1, ifreq * 3, 1

a13 poscil iamp * .25, ifreq * 5, 1
a14 poscil iamp * .125, ifreq * 6, 1
a15 poscil iamp * .0625, ifreq * 7, 1
a16 poscil iamp * .03125, ifreq * 8, 1
aOut = a9 + a10 + a11 + a12 + a13 + a14 + a15 + a16

It might be cleaner/easier to read using a more simple instr and instead adding a few extra lines and parameters in the score. Hereās an example that adds the harmonics in one at a time to create a saw:
giSine = ftgen(1, 0, 4096, 10, 1)

aEnv = linseg:a(0, .05, 1, p3 - .1, 1, .05, 0)

Again Iām not sure exactly what you want to do with instr 9. The nice thing about Csound is there are many ways to do things so itās just a matter of understanding what your goal is.
Best wishes,

Hi Scott.
So my intent is to add a fixed spectrum additive as in instr number 9 that you did. and now create a variable spectrum additive with g buzz as in instr 10.
I would like to make instr 10 more interesting so as to make it play longer.
Meanwhile the instr 8 convinces me enough but if you can take a look at it as I made it. the idea is always the one I listed in the previous answer regarding instr8. Thank you so much
Good morning St.music I wish you my best wishes for a happy new year.
I wanted to know if you had taken a look at the latest work I posted.
Thanks again
