  • At A Loss - Master Volume Control

    I am at a loss trying to figure out how to integrate a master volume knob into my setup. I plan to use the Joycon for my steering wheel control, but I'd like to maintain a master volume knob too.

    I have read various searched threads on using preamp and EQs that have remote volume but I just don't understand how to set up a system to achieve this along with the joycon.

    I plan to use an internal HD sound card for 5.1 sound. Out of the SC, I will run to each one of my amps for the speakers. Joycon can control the FE / Windows volume but what volume knob would work and how to add it. I am only guessing that I would need to plug it into a fusion brain or something? Please help me understand.
    The best forum start place is here but damned if I could find it. I had spent several weeks on the forum before finding it.

    The joycon is basically a 'simper' FB-- it looks for a certain resistance(each button has it's own resistance that is connected to it), and tells the computer when it sees it, and the software defines what happens on the computer when that button is pressed.

    If you are looking at using a external physical knob as well, then you might run into problems-- ie. You will end up having to set 2 different volume knobs.

    It might be better to try to see if a qube/fusion brain will work better for you-- because I believe that either should allow you to have 2 software volume controls that will not affect each other the same as a software and physical knob arrangement.(though I have no experience with either product, so you should check that it will work before buying one on my advice)

      Thanks for the input. The more I think about it, the FB is prob the way to go with it. Anyone else have any ideas?

        found this neat little program to change volume and eject via hotkeys

        I'm workin on using an Arduino to send key-presses to windows

        Colin's Qube will be next

        i don't know much about FB

        what kind of physical volume knob are you planning on using? i might suggest not using a regular ol' pot (comp sound > pot > amp > speaker)

        there is also a small board called U-HID, which sounds allot like the JoyCon, but i don't have any hands-on with ether.

          Sleepy, thanks for the info. I am really still in the design phase and without knowing how it would all fit together, I don't know which knob I'd use. The farthest I have gotten is that it would have to be one without physical stops.

          If I understand you correct with the comp sound > pot > amp > speaker comment... I ultimately want the knob to control the windows volume level the same was as a FB or Joycon would. I do not want the master volume to change the input levels into an amp.

            For the record, I already have all of this done via my Qube. My site is down right now (data center switching) so I can't link to it, but I have software that takes a rotary encoder (knob without physical stops) and changes your master volume in Windows Vista. I'll update this in a few hours with the link.

              Collin, please post a link when your IT issues are resolved. I am interested in what solution you have.

                Server might be down for a while. Here's some pics for the hell of it.

                2) encoder prototype

                  Oh, there's also a MUTE function if you click the encoder in.

                    hey Colin,

                    have you used your Qube to read steering wheel controls yet? There shouldn't be any difficulty with doin that, but the rest of us are still noobs to your Qube.

                    BTW is your final encoder there smooth or are there steps to it? and what is the shaft size? cause i've been diggin up some rather spiffy knobs

                      I haven't looked into steering wheel controls, but anyone could do it in theory with some software. The qube is already capable of analog readings, and most controls are resistive... most people are noobs because its still a new product, the software isnt perfect yet and there's no interface to popular programs like RR. Once that gets going it'll be bigger.

                      The encoder has 24 detents (I believe) and the shaft size is.... well I don't know. I know that the part outline is from Alps but the model number I forget

                        Thanks for the photos. What are the dimensions of the board? I am looking at two ways for my setup. I'd love to try and get the entire computer into the double din space and not sure how this would fit into it.

                        I am guessing that this would directly control the master windows volume? I would love to see something for Open Mobile as well.

                        BTW, your site is still not working correct for me. I get a certificate warning as well as photos are not showing up....

                          I forget the dimensions to be honest, probably about 0.7" x 0.85" but those are just guesses. The site does work, you shouldn't get any certificate errors unless you're using HTTPS which I don't even have set up right now so... use http://www.nilok.ca and it should work...
                          If you want to see something for Open Mobile, it's VERY simple to interface with the Qube. It's a simple HID packet, so you'd be looking for "33 FF" for CW and "33 00" for CCW.
