[Csnd] Rendering multiple instrument calls into one file / interative rendering

Subject	[Csnd] Rendering multiple instrument calls into one file / interative rendering
	Hello Everybody! I was wondering if there is a better solution to render audio, then muting instruments and do another run of my csound-code. For example: I have a csound-code, which is based on multiple calls of different instruments (100 instances of instr 20 and 20 instances of instr 30). Now i want all calls from instr 20 in one .wav file to be rendered and all calls of instr 30 in another .wav file. I thought about collecting the output of each instrument into a global audio variable and render them i another instrument, which only exists for rendering, via ‚fout‘. But i can’t get it working. How i know Csound by now there must be an easy solution for this. Also i was wondering if there is a solution for another problem. For example i’m working with an instrument, which should create variations of one sound-event. And every variation should be rendered in a seperate .wav file. I can call the instrument via ‚event‘ and have an ‚fout‘ opcode inside the called instrument. But i want to find a way to iterative go through numbers which makes the created .wav file unique and doesn’t get replace, like „Super-Sound-001.wav“, „Super-Sound-002.wav“ and so on. How can i solve this? Maybe you have some tipps für me.

	I'm lost on the question - is it that you can't get fout to work? Why the need for a seperate recording instrument as you can use fout from inside the instrument. For what it's worth, it's easy to set up fout from either inside the instr or using a seperate rendering instr by passing the audio using a global audio variable, I've done both. If you can explain a little better that would help. Scott On Sun, Mar 5, 2023, 3:12 AM Philipp Neumann, <kontakt@philippneumann.eu> wrote: Hello Everybody!

	This is a simple example, 2 instr sent via global audio to record instruments.

The answer to your second question is to use sprintf to generate a unique name

Hello Everybody!

I was wondering if there is a better solution to render audio, then muting instruments and do another run of my csound-code.
