Subject	[Csnd] UDO not working with 5.12
	Hello, I have noticed that under 5.12 that a UDO I am using, a modified version of the Decimate opcode, is not working. It simply wont pass sound through. I am using it in Max5, and when I look at what's coming out of it, it's getting NaN.... I'm sure it's not my effects instrument, as it is working with all other opcodes, and it was working fine until I updated to 5.12... The modifications that were done to the UDO were to make it compatible with 0dbfs = 1 orchestras. It's worth mentioning that I didn't make these modifications, so there may be something obvious going on that I don't understand. Still, it did work in 5.11. Anyway, if someone could run this and see if it works on their setup, I would appreciate it. Best, Jeremy Here is the opcode: opcode decimator, a, akk setksmps 1 ain, kbit, ksrate xin kdbs = 0dbfs kdbu = 0dbfs * 2 kbits = 2^kbit ; Bit depth (1 to 16) kfold = (sr/ksrate) ; Sample rate kin downsamp ain ; Convert to kr kin = (kin + kdbs) ; Add DC to avoid (-) kin = kin(kbits / kdbu) ; Divide signal level kin = int(kin) ; Quantise aout upsamp kin ; Convert to sr aout = aout (kdbu/kbits) - kdbs ; Scale and remove DC a0ut fold aout, kfold ; Resample xout a0ut endop

	yes, this is to do with the 0dbfs bug I reported earlier.

	Ah, yes, that makes sense. What a bug! At least it's known. FWIW, I use 0dbfs = 1 exclusively, and this seems to be the only thing broken.

	0dbfs=1 will work, but you can't use the constant '0dbfs' in instruments, because it will be 0. This bug happens only with the old parser. So if you use --new-parser, it will work.

	OK, so it's only within the instrument (or UDO that the instrument uses). How would I use the new parser? Sorry, still very new to Csound....
