Hi,

I am toying with Partikkel Audio's Hadron Synth. The code runs well in 
Windows with Csound5, but I have to tweak it a bit in Linux (Csound6). 
By the way, is “instance” a new undocumented opcode? They use it as a 
name for an i-variable and I am getting 'unexpected T_OPCODE (token 
"instance")'.

Anyway, I am not writing because of that. There is a part in an included 
file where the code goes:

iAmpFtno ftgen 0, 0, 2, 2, 0
ftload Sampfile, 1, iAmpFtno ; Sampfile is the name of a file containing 
a table

Each file contains a variable-sized table saved with ftsave. So the code 
creates a table with size 2, and then loads the table with the one saved 
in the file. In Windows/Csound5 that works, but in Linux/Csound6 
(unless, by chance, loaded tables are of the same size of generated 
ones) you get a Segfault. It occurred to me that you could solve the 
problem by scanning/greping the file to find out the size of the table 
in the metadata. As I couldn't find a quick way to do that, I decided to 
go for something like this:

iDummytable ftgen 99999, 0, 0, -23, Sampfile
iSizeofdtable = ftlen(99999) - 62
ftfree 99999, 0
iAmpFtno ftgen 0, 0, iSizeofdtable, -2, 0
ftload Sampfile, 1, iAmpFtno ; Sampfile is the name of a file containing 
a table

It works. But I think there must be a better way of creating a 
variable-sized, GEN02 type of table and also load it on the fly. 
Otherwise I am allocating and constructing a table just to find out its 
size each time that instrument is called. What's the right way to do it?

Thanks.

The instance opcode is called “nstance” (without the “i”)

http://csound.github.io/docs/manual/nstance.html

which version of Csound are you using? The ftsave thing rings a bell, I remember fixing a bug
there. If it is still not working in the latest code (6.06), can you file a issue in github? Thanks.
