Can someone help me out here , I've done this a million times but this is really getting on me
The uzi spits outs values 1-64
It first goes into the expr..which divides the uzi stream ( $f1 ) by the length o the table (64) , multiplied by 2pi radians .
This goes into a cosine into ( cold inlet )of float .
The float is banged only when the TBF has written it's first index .
Problem is that the first value is never written .
I've disconnected the order multiple times and the same result occurs .
Only when reloading the patch it works fine ( edit it doesn't )

@gentleclockdivider lack of a trigger on the output of uzi to determine if expr or the [t b f] get hit first could do it.

A simpler solution

also

you probably want 0-63, and help file of [uzi] tells you how to set from 0 with the 2nd argument, The trigger part is bad, you should have just first sent it to the right then to the left, but I just simplified the whole thing by just using [expr] to do it all... I am also using [loop] from ELSE which I think has a better desing and works best

I am assuming you are using PlugData, ELSE is also part of PlugData

Yet another option, [tabgen] from ELSE, which populates arrays of any size without guard points and can generate sums of sines and more... it is more powerful than 'sinesum' and 'cosinesum' also because it can take any initial phase offset and a non integer arbitrary number of cycles, so it is well suited for your task

I dont know why you say the trigger part is bad .
Sure I could have send it first to the right inlet of write and then left (which I have don previously ) , but using a TBF for the index I am sure that value at the left input ( float module ) will be triggered by tbf

but you are not sure what connection from uzi goes out first, if to expr or trigger! And you should have used trigger there to first send to tabwrite then to expr... then you also dont need [float], what you did is wrong and unnecessary
