Hi CSounders,

I'm a relatively new user of CSound, and was wondering how to get reverb (or any signal, really) to carry over between score sections. Here's what my score looks like:

s
t 0 90 2.5 125 
;instr	Start	Dur	Amp	Freq	
i 1		0	0.5	0.2	7.03	
i.		+	.	.	7.02
i.		.	.	.	7.03
i.		.	.	.	6.07
i.		.	.	.	6.08
i.		.	.	.	6.00

i.		.	0.5	.	5.10
i.		.	.	0
i.		.	.	0.2	7.02
i.		.	.	0
i.		.	.	0.2	6.07
i.		.	.	0
i 99		0	6    ;Reverb                 

/*the reverb gets truncated in order to maintain rhythm, or the rhythm gets elongated        
in order to maintain the reverb tail. In this case, the reverb has been truncated*/

s								
t 0 90 2.5 125
;instr	Start	Dur	Amp	Freq	
i 1		0	0.5	0.2	7.00
i .		+	.	.	6.11
i .		.	.	.	7.00
i .		.	.	.	6.03
i .		.	.	.	6.05
i .		.	.	.	5.08
i .		.	.	.	5.07
i .		.	.	.	6.02
i .		.	.	.	6.07
i .		.	.	. 	7.00
i .		.	.	.	6.11
i .		.	.	. 	7.00
i 99		0	6                     ;Reverb

In order to keep rhythmic continuity, I have to truncate the reverb tail. I'm wondering if there is a way to allow the reverb signal to either run in parallel with the score or to ignore score sections so I can add the reverb onto the entire score as a sort of global mix element, rather than having it be confined to a section by section parameter. 

Thanks, and let me know if this post is confusing or formatted wrong.

Agreed,
but AFAIK no instrument events can span section boundaries. One way
for you would be to render an audio file without reverb, keeping the
sections as you wish, then run a separate "add reverb" pass using this
audio file as input. Or try organize the score without using sections.

yes, something like:

instr ...

(called by the score)

instr Reverb
...
endin
schedule("Reverb",0,999)

this should work, i guess.

Oh I did not know alwayson could actually span across score sections,
but tested now and it works. Nice.

Sections last until all notes finish so if I understand correctly reverb cannot span sections.  Personally I do not use sections but rather use the b score opcode.

Seems like you could also just use the turnon opcode in the orchestra. I am not too familiar with the use of sections in the score since I mostly use Csound for audio processing and instrument design, but it seems like this would work, since it is not tied to score events. Correct me if I am wrong.

EG:

<CsInstruments>

.....

turnon "reverb"

instr reverb

.....

endin

.....

</CsInstruments>

<CsScore>

Or, you can use the b score statement instead of s.
