The phase is negative, it looks like it needs to be wrapped around. There’s code for wraparound
beyond the table length, but not for the negative case.

Adding wraparound for the negative case fixes the crash. Committed, but unsure if this is correct.

It’s the internal phase index (phs). I ran on the debugger and saw it was negative at the time of the crash. So I put in wraparound code to fix it.

Okay, I still understand half of it. I got that you used a wraparound code, but I have no idea how achieve that yet. 

I might get a clue if I get the answer for these two things.


1) What is the internal phase index?
- I still don’t understand what went wrong because I don’t know what this means. I might be able to come up with a wraparound code on my own if I understand what this is
 
2) Which debugger software are you using? 
- I might need to check a couple more times in case I can’t figure it out from the first attempt

Sorry about too much questions, I’m still new to Csound.

Thanks Victor!

Hi Marvin,

Victor made a fix to core Csound code, and you will need to get a new
version of Csound to make use of the fix.  This would require you to
compile Csound yourself or wait until the next release.  Once you have
a new Csound, CsoundQt should use it next time you start that up.

Steven

It doesn’t work like that. You would need to get the full sources using git and 
then build Csound from them. If you don’t know how to do this, you can wait
until we release 6.11, which will be soon.

To be clear:
1. The problem is generated by the CSD parameters.
2. Csound crashes due to that and CsoundQT crashes following this.
3. I fixed it so it doesn’t crash. It doesn’t produce a usable result either,
there is what sounds like a loud bang, but that’s up to you to fix in the CSD.
