Subject	[Csnd] Several instances of an UDO in an UDO
	Hi all - I've written a simple sound producing UDO called "Plopp". Now I'd like to have another UDO which has n (say: 10) layers of Plopp. Is there another solution than writing opcode Ploppsum, a, 0 a1 Plopp a2 Plopp a3 Plopp a4 Plopp a5 Plopp a6 Plopp a7 Plopp a8 Plopp a9 Plopp a10 Plopp aout sum a1, a2, a3, a4, a5, a6, a7, a8, a9, a10 xout aout endop ?

	Can't you build a recursive UDO that calls itself N number of times? Victor has a good example of this in his Vocoder UDO in the database.

	I'm with Rory and would recommend either making the original UDO recursive or make a second recursive UDO that calls the original UDO. I thought I'd also mention an article I wrote that covers recursion: http://csounds.com/journal/2006summer/controlFlow_part2.html It explains why for-loops won't work in csound for something like this and why recursion is necessary. So, for something like Ploppsum, you could use something like: opcode Ploppsum, a, i icount xin aout Plopp if(icount > 0) then atmp Ploppsum (icount - 1) aout sum aout, atmp endif xout aout endop then you could call it like: asig Ploppsum 10; use 10 instances of Plopp On Tue, Mar 9, 2010 at 8:22 AM, Rory Walsh wrote: > Can't you build a recursive UDO that calls itself N number of times? > Victor has a good example of this in his Vocoder UDO in the database. > > On 9 March 2010 10:50, joachim heintz wrote: >> Hi all - >> >> I've written a simple sound producing UDO called "Plopp".

	It took me a while to get my head around recursive UDOs but I must admit it's one of the funkier features of UDOs.

	Wow - thanks a lot, Steven and Rory. I didn't know that this kind of recursion is possible in UDOs. Fantastic feature! Thanks, too, for the instructive examples of Victor, and your solution for my problem, Steven. I just made a little change for being able to have 0 as icount: opcode Plopps, a, i icount xin aout init 0 if icount > 0 then aout Plopp atmp Plopps icount-1 aout sum aout, atmp endif xout aout endop Thanks again - joachim Am 09.03.2010 um 14:38 schrieb Steven Yi: > I'm with Rory and would recommend either making the original UDO > recursive or make a second recursive UDO that calls the original UDO. > I thought I'd also mention an article I wrote that covers recursion: > > http://csounds.com/journal/2006summer/controlFlow_part2.html > > It explains why for-loops won't work in csound for something like this > and why recursion is necessary. > > > So, for something like Ploppsum, you could use something like: > > opcode Ploppsum, a, i > > icount xin > aout Plopp > > if(icount > 0) then > atmp Ploppsum (icount - 1) > aout sum aout, atmp > endif > > xout aout > > endop > > then you could call it like: > > asig Ploppsum 10; use 10 instances of Plopp > > On Tue, Mar 9, 2010 at 8:22 AM, Rory Walsh wrote: >> Can't you build a recursive UDO that calls itself N number of times? >> Victor has a good example of this in his Vocoder UDO in the database. >> >> On 9 March 2010 10:50, joachim heintz wrote: >>> Hi all - >>> >>> I've written a simple sound producing UDO called "Plopp".
