Hello,
I am trying to use the envlpx opcode to control the frequency cutoff of a filter.
The Gen I am using is
f10612 0 4097 5 0.1 41 0.2100 41 0.1300 41 0.3400 41 0.2000 41 0.4200 41 0.1500 41 0.0000 41 0.2000 41 0.2400 41 0.4900 41 0.3000 41 0.4800 40 0.4900 41 0.4900 41 0.2800 41 0.3600 41 0.4900 41 0.4200 41 0.2200 41 0.1200 41 0.1300 41 0.1000 41 0.1000 41 0.1400 41 0.1000 41 0.2200 41 0.3500 41 0.3700 41 0.1000 41 0.2500 41 0.4000 41 0.2100 41 0.2800 41 0.6700 41 0.5300 41 0.2700 41 0.4200 40 0.1900 41 0.3100 41 0.4000 41 0.7000 41 0.2300 41 0.3500 41 0.6100 41 0.5300 41 0.6500 41 0.2600 41 0.3600 41 0.3300 82 0.4300 41 0.5300 41 0.3900 41 0.5900 41 0.5700 41 0.4800 41 0.6700 41 0.5100 41 0.5800 41 0.6300 41 0.3900 41 0.3000 40 0.5600 41 0.6600 41 0.5000 41 0.7600 41 0.6600 41 0.5100 41 0.5500 41 0.7800 41 0.7200 41 0.5900 41 0.3900 41 0.3800 41 0.7300 41 0.4200 41 0.6000 41 0.7000 41 0.4900 41 0.5700 41 0.5200 41 0.9000 41 0.5400 41 0.4800 41 0.7200 41 0.8700 41 0.9000 40 0.7800 41 0.5200 41 0.9400 41 0.4700 41 0.5500 41 0.5500 41 0.7500 41 0.6500 41 0.9600 41 0.8100 41 0.7700 41 1.0000 41 0.3400
but I have this message:

Could someone tell me why?
Thanks in advance.
Exponentials can't use zero value...
Yeah, it took me about 20 minutes to spot it, too (:-/), but in the second line of your function table (as it shows in my browser) you have a '0.0000'. Change that to '0.0001' or something and the error should go away.

Thank you Pete, I tought zero values were to avoid only in the beginning and in the end of the table.
Thanks again
exponential values
An 'exponential' value has to be derived by raising some base to some power. [The base must be greater than one -- unless, apparently, you're Captain Kirk.... In last week's "ST Remastered", he announced that the ship's sensors had been amplified by a factor of "One to the power four"! Oh... goody.]
Anyway, there's no way you can arrive at zero by raising *any* base to *any* power, so that value is always disallowed. (You can't of course cross the zero axis either.)
Confusingly, GEN05 sets any surplus cells to zero -- maybe to be specifically an invalid marker. I'd have thought maintaining the final specified ordinate would have been better, but never mind.
