[Csnd] Exponential envelopes and 0

Hi guys. I was thinking it might be nice if the exponential curve generators accepted a value of 0 and just internally converted it to the minimum non 0 value. If I was to succeed in modifying this, would that be something that would get put in the main source? I figure it doesn't break backwards compatibility at least, and (without yet having looked at the code) I'd imagine will only require a small initialisation overhead if done right

I'd find it odd seeing a zero as an input argument to an exponential envelope generator, but I'm not against the idea. I've forgotten the number of times I've had to correct this simple mistake in student's code. On Sat, 23 Feb 2019 at 16:25, Peter Burgess <pete.soundtechnician@gmail.com> wrote:

Easy enough to do as a UDO. We can't change behaviour, and it doesn't merit
a new set of opcodes (IMHO).

One problem with this is that it makes the speed of the envelope change a
lot depending on what the "minimum nonzero value" actually is.
Increasing from -50dB to 0dB in 1s sounds a lot different from increasing
from -100dB to 0dB in 1s. So in order to make use of an envelope with
this feature I need to have a pretty good idea of what the minimum value
is, and depend on that not changing in some future version, and if I have
to think that hard I'd be better off really writing what I mean instead of
depending on the system to correct my error.

Victor - You wouldn't be changing the behaviour for everyone who has 0.0001 as their "0" value, and anyone already using 0 had bigger problems right now. Mathew - The minimum value will change depending on whether float or double is used, that is true... Although you could set it to always use float's minimum non 0 value no matter what... Or a note in the manual might work instead? On Sat, 23 Feb 2019, 16:57 <mskala@ansuz.sooke.bc.ca wrote: On Sat, 23 Feb 2019, Peter Burgess wrote: |

And am I right in thinking negative values are possible for expseg etc? If so this will allow things like randomly selected values or sweeping values from negative to positive without the user guarding against zero
