  1. i am building a MB64e and i am confused, the controler take encoders as buttons. i have 2 din modules, in the first one there is 8 navigation buttons witch are working and in the second (chained to the first) there are 15 encoders witch are scanned as buttons. what could be the problem. in ,in the schematic,  the encoder din module is on J6, but the note below the schematic says it must be chained to din button module at J9. Is there a problem of interpretation? With mb16e application, when enc din module is at J6, encoders are not recognized, nothing happen when i turn encoders When enc din module is chained to button din module, encoders are recognized as 2 buttons. Thanks Loic
  2. MB64e control surface

    Today I etched a few more PCBs. Now the control surface is complete. Or that is - I haven't yet soldered on most of the cables on the new boards, but components are soldered, backlight on the menu encoder is tested, ok (looks good as expected hehe) and I laid it out on the workbench to see how I want the frontpanel to be. I think I'm gonna use this setup here, unless I get any bright ideas or any bright tips :). It has 8 general purpose encoders, 8 general purpose buttons, encoder for left/right navigation, it got the enter button (besides the menu encoder, and it got the snapshot button by itself - on the same pcb as the enter button :). The buttons is just the same as in the mb6582. I have looked around the net (especially on ALBS) and found many very cool tactile switches that I could easily used for this box, but the reason why I used these buttons is that I had them in my drawer NOW, and I had a lot of em, so I figured - simple and fast - no waiting for parts etc etc. so that's why the buttons are rather boring - but I suspect they'll do the job anyway hehe. In addition - its gonna have 4 analog inputs on the back (via mini-xlr) - for expression pedals mmmmmmmmmmmmmmm. Since I have only one pedal now, I have to have a way to ground the unsused input easily without opening the case - so I have ordered in a bunch of dip-switches. I have thought and thought, and I think this is a cool solution - dips available from the back panel. Makes it easy to "program" when I need it, and hard to accidentally operate :). It got the 16x2 LED - wich has green letters on black background, and green backlight for knobs. Any day now, the Core8, AIN, DIN and a bunch of other goodies are dropping in my mailbox from smashTV, and once I get those, I can wire everything up and actually test it. If everything works in a satisfying way, I'm building the case next - I'm doing it simple - just bending some alu plates and put together. Give it a coat and 10 of cool paint, and we're there. If I come across a case I can use, I'll do that instead of making my own - wich takes long time even if it's simple design. Well, enough talking, lets see the picture :). - yes there is only one today :P.
  3. MB64E Side project

    Yo! Just thought I'd do a small blog entry on the sideproject (I consider the synths my main projects). A midibox 64e. This is a short term project, and all parts have arrived or are on their way. It's gonna have 9 encoders, lcd and some buttons + 4 expression pedal connections. One pedal is soon built - waiting for the last parts to arrive from the states :). Anyway, some of you might have seen my picture of the encoder PCB. Now, here is a couple of pics of the finished built pcb. Also fitted on top is a PCB mockup (thick paper). This is gonna be housing all the smd leds for the knob backlights. This hasn't been etched yet because I discovered I needed to do a couple of layout changes - the leds are a bit too close to the encoder shaft than I'd like it to be... :). As you can see, this is gonna be a encoder control surface sandwitch :D. The cables are rainbow ribbon cable from tim's and I have split them up and put on some nylon stockings :P. Heat shrink tubes holds them in place ;).
