  1. OPL3 made in China

    Hi and welcome to MIDIbox! :) I'd say there is a 50:50 chance, that they are original and will work. That ebay seller in german ebay seems to  generally have quite positive feedback, but there are also some "fake component" comments. How it could work from their side is that they pulled/desoldered the chips from old hardware, i.e. old sound cards. That's also what i would recommend, e.g. get an old soundblaster with the OPL chipset from ebay for cheap and desolder with a heat gun - that way you can be quite sure it is an original! Most of all: have fun! Many greets, Peter
  2. midiphy SEQ v4+

    @Antichambre, probably the definitive version - it is nothing dramatic and should be quite easy to handle, as it will be quite modular (lots of small panels). Many greets! Peter
  3. midiphy SEQ v4+

    Andy is back from the states and has access to proper soldering and test equipment again :) Speaking for myself, we have finalized the move to the new house, thus i have more time. The v4+ modular extension is super high on our list, we are working on it: validation phase next and we need to design the eurorack frontpanels :). Many greets, Peter
  4. MIDIbox SEQ V4 Release + Feedback

    @southpole you are welcome! Maybe not exactly the same, but you could also look into the native patterns of the MIDIbox SEQ - switching them on the pattern screen gives you direct access to different notes/melody lines on a group of four tracks, so you could also replicate the 16 x 16 step parts by switching through patterns, i think. Many greets and enjoy the weekend! Peter
  5. MIDIbox SEQ V4 Release + Feedback

    @southpole maybe helpful regarding your first question - have a look at "Fx Loop" in the handbook: Fx Loop Is this an "effect" or a "tool" which is useful while editing long sequences... decide by yourself:   Global Loop Mode: following modes are supported: All Tracks/Step View: loops all tracks around the visible step view All Tracks/Static View: loops all tracks around the selected Offset/Step range Selected Track/Step View: loops the selected track around the visible step view Selected Track/Static View: loops the selected track around the selected Offset/Step range Loop: enables/disables the Loop function. Can alternatively be switched via MENU+SCRUB buttons. Many greets, Peter
  6. midiphy SEQ v4+

    Great job, Bruno, Elektruck and southpole! Sorry for my absence, we were moving and I still have to unpack a lot of boxes until normal operations can proceed :). Because there was a discussion ongoing regarding resistors for color mixing and lowering the resistor values e.g. for custom keycaps with smaller windows - the superflux LEDs should be able to withstand more current, and in my experimentation i went as low as 10R for blue and green (use a higher value for red!) - but then the currents are way out of datasheet specs - you are on your own, then! :-) Imho it would be best to play safe and go for 47R, then these LEDs should have a very high life expectancy and the superflux brightness is then also somewhat balanced with the brightness of the OLEDs and the matrix displays. To achieve the red/cyan mix as seen in the first tutorial video, you can use a single resistor going from A to 1 (red color for the running step indication) and another single resistor going from B to 2 AND 3 (cyan color for the "step has a note" indication). That second resistor results in a blue-ish cyan, as the forward voltages of blue and green are slightly different, green will not be as bright as blue. You could also try with three resistors (there is a second hole in modern LeMEC boards or you could just attach to the same pin) for fine-tuned color mixing. Have a good evening! Many greets, Peter
  7. midiphy SEQ v4+

     @mcmurray just a heads up, parcel tracking says batch #2 of the cases should be delivered tomorrow or on tuesday, will make them available in the shop, once they arrive. As a new shop feature, you can now subscribe to "back in stock email push notifications", when you are logged in and are browsing the product detail page, e.g. of the case you want. Then you get an email instantly from the shop, when they are available. There probably is more demand than supply for this second batch of cases again, but we've asked Adrian to make batch #3 a bit bigger. If you don't manage to get a case from batch #2, the next batch should be inbound again in another few weeks. We'll get there and finally stabilize supply. Many greets, Peter

    @synaptech well done - congrats also from my side, you have deserved a cold one! :) Enjoy your new sequencer! Many greets, Peter
  9. Troubleshooting midiphy SEQ v4+

    @synaptech - that's good news with the encoder! As written above, i'd recommend to thoroughly check every SMT IC pin on LeMEC L - i had more than once problems with solder connections i thought were ok. You can "reflow" them quite easily. Please check the top pins of IC2 on LeMEC L, can't really see it in the photo, but there might be some solder missing, or they might not "reach" the PCB - check from the side with a magnifying glass. Good luck! Peter
  10. Troubleshooting midiphy SEQ v4+

    @synaptech one thing that happened once or twice at my side (built 6 lemec boards in total), was that the SMT IC soldering looks good as seen from above, but there was a little gap between IC leg and PCB, which can only seen from the side - no contact on a pin. This can happen when you "push on the IC", soldering a single leg first and the IC is not completely flat on the PCB. Therefore, i'd recommend to use a magnifying glass and check the 595s and 165s pin for pin, especially looking at them from the side. Looking at your pictures, on the LeMEC L, the upper right pins on IC2 might have suffered from such a fate - it should be easily corrected by re-soldering them with a fine tip and a tiny bit of solder. Many greets, Peter
  11. Troubleshooting midiphy SEQ v4+

    Congrats on getting it working again! As you heard my grumbling passage in the video tutorial "i should really get a mac" - really meant that at that time, as Windows seems to have quite buggy MIDI-USB. Restarting MIOS Studio or even Windows can help quite often. Many greets and have fun building, Peter
  12. Hola, after about three years in the pipeline, we are proud to announce the LoopA v2. Thanks to Andy, there are now PCBs - and we have also finished a DIY acrylic case. Public availability (PCB and essential kit for hard-to-get parts) is expected somewhen in June/July, also John from Modularaddict.com did show interest and wants to resell those boards for the U.S. based folks! The LoopA will definitely not be a beginner DIY project, as some SMD soldering and somewhat precise board interconnection work is needed, but a BOM and a full documentation about the build process will be released, so it should be doable :-). On the plus side you will receive a very compact unit (only 38mm height packing three stacked PCBs), a lot of MIDI interface functionality and a very responsive system that is designed to be "easy to use" and inspirational. Like not starting up your DAW and updating drivers but just sitting at your favourite synth and hacking in some lines! :) Here are the main features: * six polynote tracks linked to individual MIDI configurations * six scenes, allowing for a total of 36 in-memory MIDI clips * graphical note display on an OLED, that shows clip notes and also edit changes like transposition in realtime * four MIDI OUT ports, two MIDI IN ports, one OUT port is configured as an optional BLM expansion port (later) * non-step sequenced recording, clips can be dynamically requantized during live sessions * note-editor for fixing recording errors * transposition, scrolling and time-scaling of clips * disk operations (full recall), storage to SD card * BPM setting and MIDI sync from "upchain" devices like a master MBSEQ Here are some photo session shots of the final unit in the case:         And here is an introduction and "basic features" video:   We will also inform you here about software updates (a few new features are planned in addition to what is already available) - if you want to give us some feedback, or have feature requests, please post them here. But: we might not implement everything, as the idea is to keep the functionality really "slim" for easy use - for everything else there is the bigger brother, the MBSEQ! :) BIG THANKS to TK. and Andy, it would have been impossible to do it without you guys! Many greets, Peter  
  13. @Wapata great, that's exactly its intended usecase! :) (you could optionally skip the DAW part, too and just have live fun with your loops, hehe :)) BLM = button / led matrix, usually used for its bigger brother, the SEQ v4+ - in the LoopA context, it would be smaller and consist of 6x6 backlit buttons to launch (and stop) clips individually. Plus it would contain an additional column for "full scene launching", just like in a quite well-known clip-based DAW :) Have a happy weekend and thanks for your interest in it! Many greets, Peter  
  14. All is correct! Two scenes have been removed to be able to store more notes per scene (all is held in memory) and to allow the upper left pushable encoder to cycle between two states when pushed. The active scene switching mode is visualized with the top or bottom LED around the top left encoder. These two scene switching modes are available: a) (default, as before) full scene switching - when a scene is switched, sync-to-measure-start all clips from the next scene - which would often "dramatically" change what is played back, as all six tracks' clips are launched from a new scene. b) single track scene switching - only the clip of the currently active track is switched to a new scene. This will allow for "subtle" changes - i.e. you could progress a drum track, playing different clips from it, while the other five tracks keep playing the same clips. These two principal modes of scene switching are necessary, as we have a mini BLM for the LoopA at least in our mental pipeline! :). It will allow direct playback access to every stored clip. Many greets! Peter
  15. Little jam on Sunday Afternoon ;)

    C'est bon! Very well done! Many greets, Peter
  16. Das ist in der Tat ziemlich unerquicklich - insbesondere da man ca 200 Pakete/Jahr versenden muss, um sich als Geschäftskunde zu bewerben...
  17. Troubleshooting midiphy SEQ v4+

    There is a number of possible reasons, from electrostatic discharge, shock (dropping) it, to that one not being as resistant to heat, a slight manufacturing diversion, or soldering it for one second to long - maybe the soldering iron was over the central part while soldering... We had some issues with the red ones in the current batch, that's why we test-burn all of them for a few hours in LeMEC conditions (assuming you are using 47R) and only ship good ones, Andy has built a cool testbed PCB for it - which could also be used for MIDIbox RGB pixel graphics arrays later on, we will add it to the shop, when we have a bit of time. So, to answer, either this one was bad undetected, developed the fault after shipping, or the handling caused it, it is impossible to say now -  that's why we put 5 of them for free into every bag of 35, so you have replacements. Can you measure the red forward voltage and compare with the other ones you have in reserve? If my theory holds, its Vf should be significantly higher than on the others, that's why it still lights up when using your DMM in diode test mode and does not light up in the LeMEC. Many greets, Peter
  18. midiphy SEQ v4+

    Agreed, the solution with tweezers and a lot of solder works nicely, had to do this a few times, too! Just try to avoid "pull-up" movements with the tweezers, as these might lift the pads. Another trick is to use two irons at once, if you have them available, even a backup 5€ cheap one from the hardware store will work :). For that, you also use a lot of solder to tin all pins first to achieve thermal conductivity. But then you heat up both sides of the smt part at once, holding both irons flat to heat up all pins. Then you can very easily push off the smt part after just two or three seconds of heating - usually no damage done and the removed part can be reused. Many greets and good luck! Peter

    Hi Gerhard, thanks a lot for your efforts and work on this! We appreciate alternative parts lists a lot, they can surely help to save quite some money! One thing i've noticed while quickly browsing it: be aware, that some LEDs may have different specs regarding brightness, for example the 5mm RGB LED for the beat indicator looks like it is a "clear variant" - i've built an early version of the v4+ with one of those and it was a lot brighter than the diffused version in the mouser BOM - therefore different SJ resistors for that LED type would be required. Or you could use one of @Antichambre 's cool aftermarket beat LED diffusors :). Generally, we'd recommend not to save too much on connectors (like MIDI ports), as your sequencer should live for many years and those connectors will be exposed to some mechanical wear and tear over time - nothing is worse than a MIDI connection going bad during a live jam! :) Many greets and have fun building your v4+! Peter

    @jingo great to hear, that you are happy - could you re-ask the arpeggiator/bus question over in the MIDIbox SEQ v4 release + feedback main thread? More people using it are watching it and at least TK. should have an answer :-). @synaptech you are not the only one - checked a few other parcels we sent on their way to the U.S. - it seems customs processing is slow at this time of the year. Might it have to do with the government shutdown? I found this: https://www.miq.com/resources/news/article/u.s.-federal-government-shutdown---u.s.-customs-and-border-protection-update/ I can confirm however, that one of the first v4+ cases has reached the continent of Australia and has been successfully delivered :). Many greets, Peter

    Hi @jingo a happy new year to you, too! :-) The new SHIFT button equals the old SELECT button, it just changed its naming convention, but offers the same functionality, as described in the manuals. Many greets, Peter
  22. MIDIbox SEQ V4+ midiphy Frontpanel Demo

    A great start into 2019! Looks very good in red/green and the melody flashback was fantastic! Many greets, Peter
  23. Aha, the magic smoke release! The rite of initiation! We all went through this, some people like me even multiple times, with back then superexpensive OLEDs :) Welcome to MIDIbox! :-) (I think you might have installed the cable in reverse thus swapping a few pins around) Many greets, Peter
  24. Starting MB6582 build

    @the_duckchild glad to hear that all works! There is a difference of filter response between 6581 and 8580 and some patches probably were made for the 6581 SIDs. You could have a look at: http://ucapps.de/midibox_sid_manual_e.html In the Ensemble menu under "FILTERs" you can change MIN, MAX, and LOG to fit to your 8580, if i remember right, especially activating "LOG" helped. Many greets and have fun! Peter  
  25. Have a Happy 2019! :)
