Subject	[Csnd] Init Pow Base with i(k)
	Hello Everybody, I am having some trouble to find a way to use the following code with k-type variables. The commented line ";k_freq ..." returns an error: PERF ERROR in instr 1 line 17: NaN in pow. I guess the intention is clear, to take the first value of the k_base variable for start the process. If i change the base to just a number (as the non commented line above) everything works fine. Also i am not sure about the i(x) code, i couldn't find it in the manual.

	Hi, Try k_base int $M_E Etc = is evaluated in k-time thus k-bass haa no value yet on i it pass yet.

	Hello Tarmo! It works amazing, thanks. That way i need to write the base 2 times: k_base = $M_E k_base init $M_E Is there a way you can write the kvalue just once? So one can use (for example) oscilators: k_base = poscil(x) So just to take the first value for initializing Regards PZH De: Tarmo Johannes Enviado: viernes 22 de febrero 18:40 Asunto: Re: [Csnd] Init Pow Base with i(k) Para: csound@listserv.heanet.ie init I meant T Saatja Tarmo Johannes <trmjhnns@gmail.com kirjutas kuupäeval R, 22. veebruar 2019 23:39 järgmist: Hi, Try k_base int $M_E Etc = is evaluated in k-time thus k-bass haa no value yet on i it pass yet.
