Whoops, thanks for pointing that out. Makes te project a lot simpler too :)

...won't you need extra holes in the panel for those? And feel free to order a panel from schaeffer if you already considered everything and have made up your mind. Even if there would be like 5 people interested in such a group buy (which I would find much), considering the shipping costs, I think it would be most economical for everybody to place a separate order. Just my €0,02

Why spend 100 euro on a panel that will probably be not the best solution for MBSID V2? Better to wait until V2 is released, see if any changes make sense (maybe not the holes in the panel, but the tekst on the panel) and then order.

No problem, I will add the button, if I use a DINX1 there is 1 spare pin anyway. If I want to connect the extra encoders I'll have to add a second DIN, but i'd want to make LEDrings for them too so that would require DOUTs as well. I think veroboard will be the way to go for this one. Cool, I'm going to fetch me some buttons this weekend :-*

That panel is madness ;D Great artwork, me likes the magic mushrooms 8) Are you going to leave it transparent? Won't that make it very hard to distinguish which LEDs are lit?

Wheee, I'm an official MBSIDV2 Beta tester 8) I think I'm going to order a T-shirt with that tekst ;D One last question before I continue: I'm considering making a very minimal frontpanel with 2x16 LCD, 4 buttons and 1 encoder. I saw this is supported for SID V1, are there any reasons (in term of functionality) not to do this for V2? I do not plan to make this box either stereo or multi-core, just one core and sid for jamming and testing, for the big works I'll wait for wilba's PCB.

I connected the midibox to MIOS studio and I am able to play with the midikeyboard again, so I think this is as far as I got without LCD connected. No Sysex messages exept the upload request at boot. I think the problem is solved. maybe a FAQ marker? "When you connect an LCD, the CAN bus has to be connected too" I am happy again, and am going for the Step A now. ...new problem topic soon maybe, considering my skills to create problems ;D P.S. forgot to mention that this was all done with Beta1 loaded, I don't think it makes any difference though.

Oops, big fault from my side, I accidentally soldered the wire to GND (I have the 5v wires for CAN and SID on the same pin, I had to desolder the 5v for the SID first, then made the mistake of choosing the wrong pin to resolder the wires to. I also made a 2 pin SIL connector to the CAN wires for testing, when the CAN wires are connected the Core doesn't reboot anymore :D But instead launching CS stays on screen. :-\ I will upload the new BETA2 application now, to see if that helps. I will also record any Sysex messages and post them. So far, thanks for your help and patience TK ;) I hope I'm not wasting too much of your time.

Soldered the components for the CAN bus (1K resistor and 1N4148 diode) together, now MIOS doesn't boot at all, only the blocks appear on the LCD ???

Or they could just enlarge the hole, use a fitting panel mount switch and solder wires to the PCB. ;D

Quick reply: I just tested the LCD with the 4 unused datapins still clamped together but not clamped to Vss and the behaviour is the same. I also checked another LCD (powertip 16x2) in both confugurations with the same results. @Jegge: all 100nF caps are in place on the bottom of the PCBs. I am now going to solder the CAN bus things, hope it helps :)

Hey you! Don't be messin' with my business boy! ;D ;)

What in the world would you need 4 sets of PCB's for??? I mean that's 32 SIDs, I am a SID freak but 32 is overkill.

I use a fully stuffed V2 Core, if the pull-up resitors were in the schematic back then, they are mounted now. There is no bankstick connected yet. I have nothing connected to the CAN bus as I am only using one Core a the moment. Should I solder the resistor and the diode and connect them both to +5v? LCD-wise, will it suffice to disconnect the ground-wire from the 4 LCD pins, or do they need to be disconnected from eachother too? With in the past I meant the last few days, a week at most. What will suffice as a control surface? Do I need the Full monty like Wilba's, or are a few buttons and an encoder enough? I would like to do the tests for you but I am nowhere near designing my CS yet, wanted to wait for the final version to be released. Will post the testresults from my last post toningt. Thanks, Alex.

Hi, I cannot be sure why the testtone was not working yesterday, but I did re-upload MIOS 1.9e a few times today. Maybe my MIOS upload was corrupted yesterday. Also, there might have been a problem with the audio connector yesterday. I use MIOS studio 7.5, downloaded it a few days ago. Had some trouble getting JAR file to run but succeeded at last. My MIDI interface is a Phonic Firefly 302 which I bought also a few days ago. During the upload, if I do a clean MIOS and the app thereafter, there are no error messages. I have had error messages in the past while uploading an application when I did not do a clean MIOS reinstall. I also have seen a message "this error is expected, please ignore" in the past, but not during my last tests with clean MIOS as decribed. Do you mean the datapins on the LCD or on the Core? On the Core, they're open, on the LCD there grounded right now. Could my problem with the SIDV2 application have anything to do with the ControlSurface which I don't have yet? There are special versions of the application for 1.7xxx when CS is absent. I will also test with a different LCD tomorrow.

yes I did, i connected pin 7 through 10 to pin 1 of the LCD. I don't think the wiring is the problem because the LCD cable is soldered to the Core, and there is a female SIL connector to the end. I soldered a SIL header to my LCD so I could swap it if necessary. As I stated, It does work with the testtone app and there are no weird characters or anything.

Hi, I don't know if its V2 related but I have a new problem. It's quite a story so I've made a new topic here: http://www.midibox.org/forum/index.php?topic=9491.0

Hi all, strangeness: when I try to run MBSID V2 beta (8580 version) or MBSID V1.74685 (8580 w/o CS version) with my CrystalFontz 20x4 LCD attached but no further Controls attached, MIOS keeps rebooting. When loading the SID testtone V1 app it works fine (produces sound and displays on the LCD). LCD interconnections also appear fine because the text on the LCD is always loud and clear. Also, MIOS is stable (displays READY.) if I upload it and then do not load an app. This is what I see with MBSIDV2 loaded: <Blocks on line 1 and 3> ------ MIOS V1.9e © 2007 T.Klose ------ MIDIboxSID V2 BETA1 Lauching CS ------ <reboot> If I leave the LCD disconnected, the app initializes and I can play with the MIDI keyboard in MIOS Studio. Strangeness ??? I also tried MBSID V1.74685, then the app message is slightly different of course: ------ MIDIboxSID V1.74685 CS not enabled! ------ Slight difference is I can't get the SID to make any sound with V1.74685 with LCD not attached, and in the the MIOS Studio MIDI monitor I keep getting Sysex message F0 00 00 7E 40 00 01 F7 on regular intervals, which to my knowlegde indicates a reboot. I have one 1 Core attached to 1 SID, both boards in V2 revision. I also have LTC connected, no MAX stuffed of course. LTC is only used for LEDs right now, no MIDI ports attached. I use my homebrew PSU. I have the LCD connected with a cable with only 12 wires, the 4 spare pins on J15 of the core are left blank. The spare pins on the LCD are connected to ground. I am completely baffled. What can be the problem?

I soldered a new plug to the audio out of the SIDboard and uploaded V2 again: it makes noise! And I don't mean digital or static noise but real SID music noise ;D One thing though: the SID testtone app did not produce any sound, just digital noise, might that app be incompatible with the 18F4685 PIC?

I would love to have semi-translucent (matte) buttoncaps but do not have the equipment to make them myself. If you're going to make some and are willing to make a few extra for me, I'll gladly pay for them and your expenses. Cheers, Alex.

Hi TK, both the Core and SID are V2, but I used the old docs to interconnect them. I will try to measure the clock signal, I already insulated the connection... Should I measure any particular voltage on those pins? Tomorrow I will also connect the sid to my amp.

But accessing those stocks could prove to be quite difficult. Can't tell without trying though, but I'm not going to.

Big synth manufacurers do not provide their spareparts lightly. In the past someone here on the forum managed to get some Waldorf spareparts. The knobs TK uses on his SID for example. I have never heard of any other succesful attempts.

OK, tests went fine. Loaded SID V2 HEX file, went fine. Still no sound :'( I connected headphones to the audio-out of the SID, is that possible or is an amplifier necessary?

I like those buttons, and would use them if it would be possible to a. aquire them and b. have a frontpanel made for them - schaeffer does not make weird shaped holes so you have to have the panel drawn by someone who's good with CAD, not me. To think of it, I still have some Waldorf buttoncaps lying around, maybe I'm going to use those after all 8)
