  1. midiphy Eurorack Expander Modules

    @sis.tm and @latigid on just had a look in the code to see what is really going on in seq_lfo.c - as a short conclusion, if a "note lfo" is used, the lfo value is rounded to an integer value between 1 and 127 to reflect a MIDI note - so even if this was put out via AOUT, that is probably not what you would want in a CV scenario (a more or less "stepless" continuous LFO waveform). Probably it would be best to ask TK. in the main SEQ V4 thread for a CV LFO expansion with non-note-steps, if possible, we'd also vote for that expansion, of course :)! Best regards and have a nice weekend! Peter
  2. @Phat, that sounds great! At some point in time, the LoopA software will probably get a CC track type, but it will never be as powerful as your dedicated CC Looper, that can just use the full STM32F4 memory for that single purpose :) Many greets, Peter
  3. midiphy SEQ v4+

    Very well done and thanks a lot for the nice report, @lp1977! Best regards, Peter  
  4. Strange behaviour?

    Hi Simon, first of all: that's one awesome datawheel knob! :) Yes, the strange behaviour without SD card is normal - the v4+ looks for the hardware configuration/layout file on SD card, from there normally the midiphy config is loaded - if it is not there, it will assume an "unmapped/standard SEQ", which does not match to the layout of buttons/shiftregisters, etc. Nothing can be damaged that way and all will revert back to normal, when you launch it with the SD card with the configuration file. The stability issue could be caused by unstable/insufficient +5V USB power. I had a very similar problem with my LoopA a few months back, switching to a better USB power supply or a high quality powerbank (for mobile use) solved it for me - could you try that out? Best regards, Peter
  5. Sammich UK PSU

    Here is a discussion with a similar question: so, from that thread, this here: http://www.buythis.co.uk/product/4927/genie-psu500-in-line-12v-dc-500ma-regulated-linear-power-supply might still work? You are probably fine with a high quality modern switching PSU as well, as long as the switching frequency is well above the audible range, especially as the SIDs are a bit noisy by themselves :).  Best regards, Peter
  6. Caseless LoopA available now! :)

    @sis.tm and @slo Thank you both very much! I am also glad it's finally out, it took too long, but there's the main job, the family and all the other distractions :) Many greets, Peter
  7. @Altitude as requested, we've now released the acrylic frontpanel plan as a SVG, as another customer wants to create a custom 3D printed case and asked for it. There is a 3mm "size indication" in the SVG, which can be used as a reference for scaling on your side. The plan is linked on the bottom of the "caseless" LoopA shop page: https://www.midiphy.com/en/shop-details/139/69 Direct link: https://www.midiphy.com/files/d14/LoopA%20Acrylic%20Case%20Frontpanel.svg Have fun and best regards! Peter    
  8. Thanks Bruno and Altitude! :) Altitude, will send you the acrylic case display cutout dimensions via PM or email shortly. Best regards and have a nice sunday! Peter
  9. Caseless LoopA available now! :)

    Thanks, ssp! All the credit for this picture goes to latigid on! :) Best regards, Peter
  10. Troubleshooting midiphy SEQ v4+

    Hi Adam, no problem to send you a spare LED, with all the "Murphy's Law" you encountered during the build! But, could you count if you don't have a spare already? For similar reasons (i.e. if one of the LEDs is defective from the start or is damaged during installation), we usually pack a total of 60pcs 2x3x4mm LEDs for a full kit, so there should be more than a single white 2x3x4mm LED left over as a spare. Have a good sunday and best regards, Peter  
  11. Acrylic LoopA available now! :)

    From the album LoopA

    Finally, after 4+ years of development! :) https://www.midiphy.com/en/shop-details/139/65/loopa-acrylic-case-essential-kit Hope you enjoy! Best regards, Peter
  12. Caseless LoopA available now! :)

    Finally, after 4+ years of development! :) https://www.midiphy.com/en/shop-details/139/69/caseless-loopa-essential-kit Hope you enjoy! Best regards, Peter
  13. And, it's finally release-day, sorry for all the delays and thanks to everyone who helped! The LoopA is now publicly available in two variants, a caseless/barebones variant, and an acrylic case variant: https://www.midiphy.com/en/shop-details/139/69/caseless-loopa-essential-kit https://www.midiphy.com/en/shop-details/139/65/loopa-acrylic-case-essential-kit Also, Adrian Hallik from Hallik Engineering is working on a new metal case, which should be available in early 2020. You can easily transplant the caseless LoopA to any case. Here is the full (2 hours +) video tutorial, all in all it should be a doable project and there are no IDC cables to build! :) And here are some impressions/photos of the kits and the final units - enjoy! :)   Firmware releases and user manual/handbook documentation updates will always be posted/linked in the first posting/on top of this thread! Have a great weekend and hope you enjoy the LoopA! Best regards, Peter
  14. Open source documentation for MIDIphy stuff?

    Probably it's best to keep the personal discussion in private via PM, no public fighting please. Will lock it for now, can be reopened if requested and if nonpersonal technical/legal discussion continues. Have a good weekend, it's a hobby, take it easy! :) Best regards, Peter
  15. Open source documentation for MIDIphy stuff?

    Please define "open" - anything that has been released in the recent decade or so, is based on TK.'s designs. This ecosystem, the MIDIbox hardware platform is fully documented, with free schematics and there is full source code available, everything is free for personal usecases. That's an awesome gift from TK. to the world! "Manufacturers" like Wilba/SmashTV, now sold via modularaddict.com or midiphy.com have just added a few bells and whistles to TK.'s ideas, like some fancy OLEDs or just added nice cases - but the base, the ecosystem is always the same, the modular, fully documented MIDIbox hardware platform. As "product development" takes time, effort and money, these manufacturers usually opt to protect their investment by not fully releasing e.g. CNC case plans or gerbers. These "products" are ok'ed by TK. for the reason, that a broader base of users can have access to the MIDIbox platform. Otherwise, creating everything from scratch will take time. E.g. i've built my first SEQ v4 completely from scratch in 2010, back then i had the time for it and it was an awesome experience (it's even documented somewhere in the forums with a photo tutorial, search for "ebony seq v4"). But not everyone wants to do that, or has the time for it. So, to answer your question: assume everything listed on ucapps.de is released under a "free for personal use license", everything sold commercially has to have been "ok'ed" by TK. before and those products do not automatically inherit full disclosure obligations of every file needed to create the product. If a "vendor" asks TK., if it is ok to release a MIDIbox-based product commercially, TK. will always ask for guaranteed customer support and probably look for a good track record in the forums of the respective creator over some years. Speaking for midiphy - in your own project, if you ever plan to use any unclear feature of our products, e.g. how the superflux LEDs are controlled, how the activity matrix is driven, or what is necessary for noiseless OLED operation, just ask the respective questions in the forums and i am sure you'll get technical and detailed answers. Best regards and have fun creating! Peter
