I use the receptor with my band, and cover a lot of of horn parts. I am trying to set up an effects VST to do a simple filter swell so that I can control the swell of brass instruments live with the data entry slider on my MIDI controller. I have attempted to set up Frohmage in the effects section of receptor, and have it recognize the data entry on my Roland keyboard, but I don't understand how to get the midi info from the data entry slider to change anything in the vst plugin. I am totally confused by the NRPN code that appears when I open Frohmage in faceless mode. Auto binding on Frohmage doesn't seem to work either. Any suggestions?
Thanks,
Andy

this is indeed one of the more complicated parts of receptor; automating parameters via MIDI. NRPN is definately not the most user friendly way either. Receptors helps by displaying the adress you have to sent the message to in hexadecimal values. example: Filter Cutoff = B0 63 20 B0 62 02. This looks more complicated than it is (although its pretty complicated). The NRPN adress you need to send to has 2 parts, which are revealed in the just mentioned code. It's the 3rd and 6th pairs of 2 digits. In this case its 20 and 02. What you need to do is find out how to assign a fader on your midi controller to send out an NRPN message, which should be in the user manual. Then you have to send it to the adress 20 02 on the channel you have the plugin instantiated, and it should work. one potential problem is the 20 02, because this is a number in hexadecimal code where 20 is the MSB and 02 is the LSB. It might be that you have to enter the adress on your midi controller in a decimal value which means that we have to do a little calculation. 
The nice thing about this NRPN system is that it works the same for every plugin and every parameter, so once youve found a way to easily access it, it becomes very straightforward; read the adress, enter it on the midi controller and it will always work

Thanks for the info, deRoland. I have a Roland A-37 keyboard controller, and the manual doesn't discuss how to send NRPN. I am new to midi programming, and it gets confusing when one considers midi channels, controller cc's, NRPN, patch change, controller assign, etc. It looks like I may be out of luck if my keyboard only sends midi cc's.

Not long ago, Geg Holmes was kind enough to explain the following to me:
a) When you have a VSTi in Receptor's SOURCE slot, it receives MIDI notes and note-related data.
b) When you have something other than a VSTi in the SOURCE (e.g. an AUDIO SOURCE or PLUGIN AUDIO FEED), then the first FX in the chain receives MIDI.
c) With "Route midi CCs to source plug in" OFF, the Receptor mixer receives MIDI CC, RPN, NRPN, etc.
d) With "Route midi CCs to source plug in" ON, then the SOURCE or first FX (if there is no source VSTi) will get CC, RPN, NRPN, etc.
So, this means that if you wish to route a VST instrument through a VST plug in effect and you wish to have the effect receive midi CCs, you need to use two Receptor mixer channels and set them up like this:
1.) Load the VSTi into the SOURCE of Receptor mixer channel 1.
2.) Turn the volume of mixer channels 1 all the way down.
3.) For the SOURCE of Receptor channel 9, choose PLUGIN AUDIO FEED of CH1.
4.) Load the effect (Frohmage) into the Effect A of Receptor Channel 9.
I don't know what Midi CCs your controller's data entry slider can send, and I also don't know what controllers Frohmage can use to control filter frequency. However, if you can get these two things set to the same CC#, you will need to follow the above instructions to get the midi controller
messages to Frohmage.
