Hi,
[Warning] Warning
Although Csound will not protest if ftgen is used inside instr-endin
statements, this is not the intended or supported use, and must be handled
with care as it has global effects. (In particular, a different size usually
leads to relocation of the table, which may cause a crash or otherwise
erratic behaviour.)
So, I imagine what you want is to use ftgen statements outside of instr
defs, but obviously still within orchestra code...that's certainly how I've
always used it! :)
Best,
AKJ

I use ftgen in instruments. I wrote an article a while back about
creating encapsulated instruments[1] that shows the general technique
using ftgen with chnget/chnset.

Use ftgenonce, which is designed for this use. See the manual entry for
ftgenonce for an explanation and example.

Mike

Hi all,
I tried to insert a ftgen declaration, not only in the orchestra part, but
in an instrument itself. This works, but unloads and reloads the ftable at
WARNING: replacing previous ftable 1
Is there a way to avoid these unload-reload operations, or is my idea to
insert a ftable directly in an instrument not recommended ?
Greatings,
Sergio

Hi all,

OK : ftgenonce is perfect for my actual needs ; ftgentmp deletes the ftable
after each note, that means it must be used in certain particular cases.
Thank's also, Steven, for your explanation about encapsulated instruments.

Greatings, and thank's to all for this help.

Sergio
