Hi James,

the definition can be now downloaded from HERE.

If you zoom into the data dam component, you see a small "+" appearing there. Pressing that, you get more inputs.

Hi Toni,

Im working on learning grasshopper for a school project and I find this to be fascinating. I was wondering If you can share the definition or let me know what you used on the canvas. I'm having trouble figuring out how you got two inputs for the data dam. Mine only has one A input.

Thank you! Got it

Hi Yuliva,

the "offsetting" of the curve in Y-direction is done by gradually increasing the Y coordinate on to which the new curve is drawn. So technically it is not offset, but it is only drawn to a new location.

The Y increases in 0.1 increments (the number in the first panel). The number is passed through a "Data Recorder" (Params/Util), which "memorizes" all incoming "0.1" and creates a gradually increasing list of them. The next component is "Mass Addition" (Math/Operators), which adds all the numbers in that list together, and that is how you get the Y coordinate.

Hi Toni,

how did you offset the curve in y-direction? 

(I am pretty new to grasshopper, cannot recognize all the components on the canvas)

Thanks in advance!

Sorry Andy .. bad my network. I tried The Firefly website from an other pc and network . things were fine. I downloaded the latest build,Installed and things r working fine. Thanks again for the Great plugin.

Hi Shridhar,

The audio components should be available.  My hunch is that you have the wrong Firefly version (32-bits vs. 64-bits) installed on your machine.  First double check the version of Rhino you are using.  Then re-download the correct Firefly version.  You may need to uninstall your current version of Firefly (using Add/Remove Programs) before re-installing.

I tried Toni but something is wrong .. firefly website is not accessible .

Check that you have the latest Firefly version and every comnponent gets loaded correctly:

I'm using Firefly version 1.0067 (with Rhino5 and Grasshopper version 0.90056).

Thanks for the reply Toni . i m using firefly but I havn't seen that component in my AUDIO section. i observed your screen capture .. i m missing those components.
