Hi,
is it possible to set the index of an array, eg. some_array[index], as an argument inside a SynthDef? Every time I try to do this I get the error that ‘Index not an Integer’. It being a variable all is fine.
Best,
pt
Hi @Petros_TatPsi ,
there’s a few things that might be going wrong here, can you post an example to narrow it down for us?
T
yes, so the SynthDef uses the following arrays:

try just putting .asInteger to make sure the value is an integer.
Were exactly should I put it? I tried but it still gives the error.
I tried inside the .at method and as pl=pl.asInteger
Use the Select UGen to index into an array based on a server-side signal.
The at method is language side only. You can’t use a server-side value to index with at, only with Select.
