That sounds like you are expecting these buttons to actually switch on/off the output of the respective SID. That is not the case. The meaning of this selection is that while programming/altering a patch, you can determine if changes should affect only one or both SIDs. That way you can program patches where the two SIDs do different things, i.e. are really stereo. To stop one SID from playing you'd need to first select e.g. SIDL, go to the OSC menu and disable all three oscillators. You'll see that only the left SID is affected by this change :) S

what exactly is your question? "It works perfectly, so does that mean there's something wrong?" - I guess if everything works fine, there's nothing to worry about :) S

As far as I know the HD44780 only has support for 8 custom characters. yes, it's GLCD then - HD44780 is the only character mode display directly supported by MIOS :) But if timing is not very critical, there's an easy solution: just get a GLCD with T6963 controller (they're quite cheap e.g. on eBay) and use it with the vertical mode driver. S

That would be a bad deal for you - I'd suggest you sell the SX64 on eBay and use the money to buy at least 10 new SIDs from Wilba! These things are collectors items and regularly go for more than 200 Euros on eBay. S

As far as I understood the meaning of this thread, this is NOT about PCBs. The kit doesn't contain any PCBs and ONLY people who already have acquired PCBs from Wilba in the first round were meant to post here that they're interested in a matching parts kit. All others (i.e. who don't have PCBs yet) will be taken care of later. S

[ X ] More pics? :D

With only one core, just don't press the SID2 button :) The names of the SID1..4 buttons are a bit misleading out of historical reasons. In fact you select a SID pair (or another core) with them. what you probably want to do is press shift and select L,R or LR to get access to only one SID of a stereo pair. S

I'd recommend reading the user manual / description pages of SEQ and MBCV thoroughly to find out what set of features really fits your needs. On a sidenote, the newer versions of MBSID also have very impressive CV functions built in, so you could also build a "MBSID" without SID module and only basic control surface and get extensive modulation possibilities, 6 LFOs, 2 EGs etc. You can configure the CV out channels to output the pitch, cutoff, resonance, pulsewidth etc parameters of the sound engine and use the mod matrix to map various LFOs, Envelopes, trigger events etc to these outputs. This solution is maybe harder to fully understand but the possibilities are endless :) S

did you find any more detailed specs like dimensions? I might be interested to buy some - maybe a little bulk order?

Kann er ja, muß sich nur mal trauen das Ding anzuschalten, gell MTE? :D S

It is possible to use J5 without AIN module, but I'm sorry to tell you that these pics are completely wrong :) you wired the pots as if they were encoders. With pots you need to connect the outer pins to Vs and Vd and the middle pin to one of the A pins. The second pic is also wrong - wired like this, one of the analog pins would be not connected to anything as long the button isn't pressed, i.e. you'd get random readings. the other pin would read Vd regardless of the switch state. I don't think it makes much sense to use J5 for "Min/Max" buttons, you could do that the normal way. If you really want to do that, use a double pole switch (that connects one pole to one of two other poles) that switches either Vd or Vs directly to one A pin. S

cool :) please share your experiences - I think you're one of the first NG builders who goes public about it, I'm definitely interested to get more feedback :) S

did you configure the application for AOUT_NG? (setup_mbseq_v3.asm: #define DEFAULT_AOUT_MODULE_TYPE 2) did you install the jumpers correctly? are you measuring nothing at all (0V) or an unchanging value? Did you follow the instructions here: http://www.ucapps.de/midibox_seq_manual.html, section "AOUT Port"? I didn't use a MBSEQ yet, but from the manual I get you need to configure AOUT as "Midi out port" on the Track Event page. S

THAT'S CORRECT!!!!!! :D S

different pin names are no issue - most pins on the core are generic I/O pins of the pic, so what you use them for can depend on the application. But you're talking about J6, which tells me you're using the wrong interconnection diagram. I know that the NG documentation doesn't talk much about other apps, that's because I don't have e.g. a MBSEQ at hand. Perhaps I need to elaborate that section a bit more... Quote from the existing doc: That means, the linked PDF is (only!) valid for MBSID. For all other applications, please take a look at the AOUT page, section "pinning". On the core side, the connection depends on the application you're using. The NG has the same connector layout as the "old" AOUT, that means you need to connect it exactly the same way as you would an AOUT. S

well to be more precise, MB64 can generate Note On/Off signals but that's mostly meant for things like the stop control you've mentioned. I'm not saying you can't use it for sending notes, just this isn't the standard application of MB64 in any way, so don't expect any master keyboard features from it. Take a look at the Midibox gallery, section "MB64 based projects" and you will see there isn't any box featuring a keyboard :) MIDIO128 is the application people normally are using for midification tasks like what you want to do. It features 1:1 or martix scanning of up to 128 keys. I never looked very deeply into MIDIO128 myself but I think it also doesn't feature too much master keyboard stuff, so maybe for "only" 13 keys the MB64 approach wouldn't be too wrong for your purpose, just don't expect it to suit perfectly without your own program modifications. S

no news :) I've been quite busy with other things in the last weeks and will continue to be so, so this project isn´t really top priority for me right now. But as the results are very satisfying anyway, all that needs to be done is maybe another evening of testing a few things like CV tracking etc. and laying out the PCB with changed supply connector and a bit more space around the filter caps. This shouldn't be too much work, so thanks for reminding me, I'll get going soon again :D S

Oh yes it does. the MB64 is a controller in the sense of "knob box", i.e. a device that sends out control data to control something else (software/synth...). There is no standard transpose command in the midi standard - if you usually want to control one certain synth, you can check if it has a proprietary transpose command. The MB64 does neither generate actual midi note information nor does it usually process any note information (which would need to be fed through it for processing). So transposing is definitely no "normal part" of what MB64 (or in fact any similar controller) could do. I'm not sure I understand what exactly you want to do/build? If you mean "Controller" in the sense of you want to midify some existing pedal board to become something like a M-Audio Oxygen, MB64 is the wrong approach - take a look at MIDIO128 and the Midification board instead. S

That's because MB64 is a controller (i.e. twiddler box) and not a synth or midi processor. MB 64 is not meant to get note information fed through it, and there's no universal "Transpose" command you could send from the MB64 towards a synth, so there's no way to "control" the transpose externally, you can only process midi notes to be transposed, and that's not MB64's purpose. The Pitch Bend trick would work but isn't the most elegant solution. S

yes, visit microchip.com and download the datasheet :) S

I was about to suggest reading the changelog, but both in the 1.1c archive and on ucapps it's still only about 1.1b - so - TK??? :) S

on some synths (e.g. the good old Korg M1 IIRC) you can set custom scale detunes for each of the twelve notes - I suppose, keyboards marketed as "oriental" have some built in tuning presets matching the cultural region they're targeted for. The problem with a sequencer is that the midi standard doesn't provide means to transfer anything else than the European "Twelve notes, equal temperament". And to be honest, there's probably max 1-2 other Midiboxers who would be interested not only in the "chromatic scale quantize" as it is now but in differently tempered original scales. So the easiest thing would be to use a synth that supports microtuning of scales. Anyway here's another idea: As long as you're using a separate Midi channel for every voice and set every channel of the target synth to e.g. 2 semitones pitch bend range, one could program a method where a pitch bend value is sent before every new note matching the scale you want. It would maybe be possible to modify the seq to do that on its own, but it'd be easier and more flexible to use another core with a little app that does this mapping. should be only a few dozen lines of C code. If you'd want more than one scale, you'd need either a small control surface or a way to select the scale via patch changes. S

I didn't measure the current until now - if you've got the bipolar option installed, this will need around 60mA. besides that it's only two TL074s whose consumption depends mainly on what you connect to the CV outputs. But I guess the max total consumption should be around 100mA. S

right, and the described behaviour is typical when no "suitable" bankstick is found. So you probably have only one bankstick connected - for saving ensembles, you need a separate additional bankstick. S
