why would i need to recompile? don't I have to open it up in wordpad, edit it, and save it? then I just upload the hex file.

could someone at least tell me if this is a software issue or a hardware issue? ??? i've inspected each solder point thoroughly to make sure i don't have a hidden cold solder. but i really don't think that is the issue because the actual pins of the chip have a connection with Vss --the ones that have no pots. I've reread the code in the setup asm, but i don't see an issue popping out at me. i have a hunch it has to do with the code. is it safe to remove complete blocks of the code. in other words, can i just have the code for the four pots and the lcd? that means taking out all the code for stuff i don't use like DOUT, DIN, and AOUT? Am I going in the right direction?

i actually did that under "setup_midibox64.asm"

Hey there, I just built a core kit from smash tv. I tested it and I have been able to upload the MB64 app successfully. I am using 4 pots just to test it out and have the rest of the inputs grounded; no mux. I have verified connectivity with my multimeter and inputs A4-A7 are rightfully grounded. My problem is that I am getting random midi messages. When i boot up the device, it boots up normal and without touching anything, my lcd display says: [int] N ________ Reverb # 1 0_ So then i turn a knob and BLAM... random midi messages galore! On bootup i get an upload request... then this after turning a knob in MIOS Studio. 00000000110663 ms | [bB 5D 21] Channel 12: CC Effects 3 Depth value: 33 00000000110664 ms | [bC 5D 21] Channel 13: CC Effects 3 Depth value: 33 00000000110666 ms | [bD 5D 21] Channel 14: CC Effects 3 Depth value: 33 00000000110666 ms | [bF 5D 21] Channel 16: CC Effects 3 Depth value: 33 00000000110675 ms | [bD 5D 22] Channel 14: CC Effects 3 Depth value: 34 00000000110677 ms | [b8 5D 23] Channel 9: CC Effects 3 Depth value: 35 00000000110680 ms | [b9 5D 23] Channel 10: CC Effects 3 Depth value: 35 00000000110681 ms | [bA 5D 23] Channel 11: CC Effects 3 Depth value: 35 00000000110682 ms | [bB 5D 23] Channel 12: CC Effects 3 Depth value: 35 00000000110683 ms | [bC 5D 23] Channel 13: CC Effects 3 Depth value: 35 00000000110684 ms | [bE 5D 23] Channel 15: CC Effects 3 Depth value: 35 00000000110685 ms | [bF 5D 23] Channel 16: CC Effects 3 Depth value: 35 00000000110690 ms | [bE 5D 24] Channel 15: CC Effects 3 Depth value: 36 00000000110693 ms | [bF 5D 24] Channel 16: CC Effects 3 Depth value: 36 00000000110697 ms | [b8 5D 24] Channel 9: CC Effects 3 Depth value: 36 00000000110699 ms | [b9 5D 24] Channel 10: CC Effects 3 Depth value: 36 00000000110700 ms | [bA 5D 24] Channel 11: CC Effects 3 Depth value: 36 00000000110701 ms | [bB 5D 24] Channel 12: CC Effects 3 Depth value: 36 00000000110702 ms | [bC 5D 24] Channel 13: CC Effects 3 Depth value: 36 00000000110702 ms | [bD 5D 24] Channel 14: CC Effects 3 Depth value: 36 00000000110708 ms | [bC 5D 26] Channel 13: CC Effects 3 Depth value: 38 00000000110711 ms | [bD 5D 26] Channel 14: CC Effects 3 Depth value: 38 I get a lot more than that. Any clues to what's happening? I did a search on random midi messages, but I don't see what I'm missing. I even checked the pins of A4-A7 to make sure they're connected to Vss. I'M STUMPED! a little help please?

initially when i completed the pcb i had a short when two solder points were touching, but that was it. i performed the short tests that i read on the mbhp64 walkthrough. the interface that i'm using is a brand new m-audio uno. i had to get it because my other interface is the firewire m-audio projectmix connected to my g5... my windows laptop does not accept firewire. by the way, thanks a lot stryd, you've been a great help.

i have 4 pots attached to it with the rest of the other inputs grounded. I have no other modules attached. i'm using the smashtv core. the protection diode is in the correct direction. the purpose of this device is to control traktor 3. i bought an opto last night so i'll be getting it by next week. if the device were to be working with other devices, i should get a reading in mios studio as i confirmed with anoter midi controller. the problem was that i was trying to upload the sysex, but i wouldn't get a response back from the core. You know, when uploading sysex in mios studio there's the option of waiting for the core to reply for the next sysex chunk to transmit. well, i wasn't getting any responses so i forced the upload. I confirmed my interface is working fine because I can see the midi out (fromPC) LED blink with every chunk sent. So at that point i fired up traktor, i set a certain parameter to the cc value of my first pot and nothing. from that point, i went back to mios studio just to see if i were getting any signal at all... but nothing. I have a feeling it's my opto, i'll admit that I didn't handle it 100% safely. I'll go over those few tests again to see if i get the same results. I don't think it's a physical problem with the pcb because i performed continuity tests with my multimeter and everything was in order.

test in4: failed test in5: failed test inout: passed test sw1: unsuccesful test sw2: unsuccesful.

OK, here are my results from a thorough troubleshoot. • TEST PROG1: OK • TEST CORE1: OK. • TEST CORE2: n/a • TEST CORE3: all solderings are good. • TEST CORE4: all connections have solid readings except at Rx with 0V. • TEST CORE5: all connections are solid. • TEST CORE6: OK • TEST CORE7: OK • TEST CORE8: OK • TEST CORE9: OK • TEST CORE10: OK • TEST CORE11: OK • TEST OUT1: Flickering OK • TEST OUT2: n/a • TEST PC1: ok • TEST PC2: OK • TEST IN1: OK • TEST IN2: ok • TEST IN3: no flickering. Also verified if led works. • TEST IN6: no flickering • TEST IN7: when I took the octocoupler out and created the 2nd standalone test, I got a reading of .13V when the circuit was closed. However, I got 0V when the circuit was opened. Does this mean my octocoupler is kaplooey?

thank you for the attention. I should have a complete listing of the troubleshooting guide in about 7 hours. I feel confident that my problem will be resolved withing 24 hours.

Hello everyone... i have built my first smashtv kit. I am powerinig through usb and am getting solid readings at every point according to the troubleshooting guide except at Rx. I have signal at octocoupler and Tx. I have 4 pots connected without an AIN and have the remaining inputs grounded.

I'm so stressssssed out that research is becoming clouded. I just don't understand and have a brickwall on my forehead. I have verified that all of my soldering is on point. i'm beginning to get depressed.

ok, so i was getting an upload request the entire time. I dled midi-ox and i have uploaded the application. looking to get to next step, i'll get back with you guys.

ok, stuffede the midi in components, was able to get sysex id to popup in mios. have dled the midibox64 application... thanks to you guys! have gone in the asm and have made basic changes such as number of pots and deactivation of mux since im only using 4 pots. however, im not getting an upload request. just giving you guys an update of my progress, looking into upload requests and such. any tips would be appreciated at this point. also, i was just teasing stryd. as i was typing in this post, i had a gut-feeling i was gonne get told to search and blah blah blah. I just get so fried from all the research after a hard days work crunching numbers and doing presentations all day that it makes my comprehension of the research challenging. you know that fuzzy feeling you get in your eye-socket and eyelids? that's me 120 hours a week. lol :o

I've researched for 4 months. In fact, I've done enough research that I was able to anticipate specifically you posting comments about me not doing enough research if i were to post a question about something I couldn't find the answer to on my own. Sometimes it's about not knowing what questions to ask.

Thank you so much! I am leaving work now to take care of that. I completely misunderstood that concept.

That's what I don't understand. I bought a preprogrammed chip that is supposed to have everything i need, why do i have to upload anything? I never anticipated sending instructions to my device so that is why i never put in the Midi in components. I'll do that tonight and post an update. In the meantime, any other ideas?

i bought a pre-programmed chip from smash tv.

My trigger finger uses alpha sliders and linear pot's. However, the dc-input plug requires a 9V adapter. I connected opened MIOS Studio and got absolutely no signal, but got signal on midimon. It's not my midi interface or plug because I use them frequently. I even used them today on a mix. In regards to your recommendation to using a stable 5V supply, will the addition of the 7805 stabilize the power. :-\

well, i've measured the incoming power and the power going through the pots and it is stable. The incoming signal is 5.03V and fluctuates from 5.02 to 5.04, but not a really significant power fluctuation. Also, how do the commercial midi controllers get their power from usb? i have opened up my m-audio trigger finger and don't see a step-up transformer or anything obvious.

Hello everybody, i have built my first midi controller using the kit from smash tv. The intention for this device is to control Traktor Studio 3. So I bought the kit and didn't use all of the components because: A) I don't need an LCD Screen. B) I don't need incoming signal. In other words I do not intend to send midi instructions to my device. C) I didn't use C5 or C6 (capacitors connected to J1) because I am supplying power from my computer's USB port. I have put together an AIN Kit too and have only connected 4 pots to it just to get give it a simple test. I am providing power from usb, have all of the unused inputs connected to ground of the cable. I connect the MIDI cable, fire up midimon which is a terminal software on mac os x, and the log says that it resets every so often. I'm not getting a real CC message. I'm not sure what to do at this point, I have connected my multimeter to Tx and am getting a strong 5V signal. Have tested all the points and have even verifired outgoing signal from the AIN to the inputs of the core. I throw my hands up in despair. Please help.

Hello, I am building a midibox64 to control Traktor. This software allows you to control 4 "decks" simultaneously. I am in the design stage and ordering parts here and there, so I still don't have a functioning system yet. One thing that I want to accomplish is to have only controls for 2 decks at a time, but with the option to control deck 3 and 4 too. In other words, I want to control 2 of the 4 at a time. The midi configuration in traktor allows me to specify a midi channel for each control. The midibox will have 2 sections, deck 1 and deck 2, side-by-side. I want to place buttons to be able to assign that section to any of the decks. So deck 1 will have buttons that allow me to control deck A and C and deck 2 will have buttons to control B and D. Are you with me? I'm thinking that when this "assign" button is pressed, it has to switch the controllers for that specific section to another midi channel. I want to program the configurations in Traktor as follows: Controls for Deck A are on MIDI Ch 1 Controls for Deck B are on MIDI Ch 2 Controls for Deck C are on MIDI Ch 3 Controls for Deck D are on MIDI Ch 4 I'm guessing that there's code somewhere to accomplish this, but I want to the MIDI Channel selection applied to certain pots/faders but not all. I have been looking for a week and can't find anything even remotely close to a switch used to change the midi channel. Please help, my eyes are bloodshot from all the research. :o
