  2. Is it possible to make a roll with a decrementing or incrementing distance between steps? It appears you can do it with Midi Echo, but I'd like something that I can use just for specific steps, with different settings per roll.  Midi echo method that I think does this: " Ticks: defines the gradual change of the delay between each repeat between 0..200% " I would like the distance between steps to be able to grow or shrink with each repeat of the roll. It could be represented with a negative or positive percentage increase per repeat. This is a feature I've always wanted in a sequencer, and they never seem to be able to do it. The usual way I accomplish it, I can only do with samples, by reducing or increasing the length of the loop on an envelope. I'd love to be able to do it with rolls to use with a drum synth.

    Yes!!!! You made my day!!!! :-) Thanks so much!!!

    I'd recommend Reichelt for MEC switches. Conrad also sells them, and the caps I think are cheaper there.

    Hi Peter, I'm happy I can contribute a little bit back after lurking all those years :-) Concerning the LED, i've marked it in red now which means parts where people should be careful in replacing. And I checked my previously bought MIDI ports again from both Tayda and Mouser and it's true Tayda seems much cheaper and doesn't have a nice metal casing. I marked those, too. Another thing I noticed, not related to Tayda, is that the MEC switches are out of stock at Mouser now. too many SEQ V4+ builders? :-) I did find some at RS so might order from there (unless someone has a huge stock and wants to make a nice offer), but i'll eventually add more columns for other vendors Cheers, Gerhard

    Hi everyone, just finished my first V4+! -->Big thanks to Peter and Andy for their great work (and support) to make this machine happen!    After playing around for some hours I found out one issue with my build: Always the eights encoder (8 & 16) do not react as expected. The encoders are jumping in the wrong direction and also opening random-like pages/functions when using them. :-(

    Hey, If you need more just tell me ;) Best Bruno

    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

    Hi Smithy, just saw your post. i was the user requesting (and now providing :-) ) the Tayda BOM. it will be only a partial BOM since they only carry quite basic parts. for now the BOM lives on Google sheets: https://docs.google.com/spreadsheets/d/1TFORmEMBbFG3oqMcv7UKvtxkn49CxaHfWDaHRXMIvfM/edit?usp=sharing in principle i agreed with Hawkeye and Andy to share only once confirmed, but I've decided to go through my stock first (including scavenging some unfinished midibox builds which are now on hold ;-) ) and use parts I already have instead of blindly re-ordering everything from Tayda. so i will only order what I can't find at home, but maybe someone else finds this list useful in the meantime.  most of the parts i have are actually from Tayda already. i can make this editable to anyone interested and you are free to copy and host elsewhere if Google is not the preferred host. Cheers, Gerhard
  12. hello ive got some older midibox stuff that i do not use anymore. maybe somebody stil has some use for it 1x pic based core 1x lpc based core (with seqv4 software) 2x din R5 board 1x PIC PROGRAMMER (with printerport connector and power supply)   1x pic18F4520 1x pic18F4620 1x pic18F4685 2x panelset (front and back panel for the TPD track position display 3x LCD display   selling the whole lot in one go for ....20 euro
  13. And a single CPU, an STM32F4 to take advantage from the MIOS32, AND good ADC with multiplexed input? An 8 inputs ADC with eight (8:1) multiplexers will give you 64 inputs ;)
  14. I've been thinking. Setting everything up with discrete components that are compatible with any µC is not really economical. The only option I see is to use multiple microcontrollers in SPI Slave configuration and run the main processing code on the midibox core. I'm not sure if this is still interesting for people as we they will need to buy programming hardware or preprogrammed µCs. ATtiny controllers can provide 8 ADC channels at 1€; 6 of them would do the trick! But I guess this still is too offtopic for this community
  15. dipCoreF4 and dipBoardF4, a compact Core.

    No I can't, it depends on the functions you need on your 'mainboard' and the ones you already mapped. Best Bruno  
  16. dipCoreF4 and dipBoardF4, a compact Core.

    I'll look into it ;-) You don't have any suggestions which pins I can use? :-)
  17. dipCoreF4 and dipBoardF4, a compact Core.

    No no there's no problem for that, this is just a bit dirty in code for the moment, and I have to complete it, I didn't write any callback installer for the HID for example, this is toDo. I can share, I already shared it with my dipCoreF4 beta testers ;)
  18. dipCoreF4 and dipBoardF4, a compact Core.

    Got you... but changing the pins for SPI2 in MIOS32 firmware shouldn't be that hard. So I could move those functions to other pins. But I don't have a clue how to implement that second USB port in the firmware... and I assume you don't want to share this informations which I can totally understand.
  19. dipCoreF4 and dipBoardF4, a compact Core.

    In this extended chart you can see the functions available for each pin, (It's from stm32f4 documentation.)
  20. dipCoreF4 and dipBoardF4, a compact Core.

    In MIOS32 the problem with the 407 is that the pin for the second USB(OTG_HS) are used for SPI2 which is your J8/9 Spi port. Then on the dipCore I moved the SPI function to other pins . AND I implement it in MIOS32 ONLY for the DipCooreF4. In MIOS32 the DipCore has is own pinout and functions.  
  21. dipCoreF4 and dipBoardF4, a compact Core.

    My mainboard uses the 407. Hm... there is still something I do not get. The discovery-boards use the micro-USB-connector for USB-Host-Mode. That means, when connecting a device (mouse or MIDI controller) to the discovery-board via this board it's not possible to connect to the core itself through USB (because the USB-port (PA12 & PA13) is blocked through the device). But in your video I see that you still have your core connected through USB to the computer. How did you do that?? :-) 
  22. dipCoreF4 and dipBoardF4, a compact Core.

    You want two USB with HID support. Which uC you use on your 'mainboard'? I implemented the second OTG HS for the STM32F405RG, coded in MIOS32 with/for the DipCoreF4 pinout. I just put an STMPS2141STR as protection, the same as Disco one. https://www.st.com/content/ccc/resource/technical/document/user_manual/70/fe/4a/3f/e7/e1/4f/7d/DM00039084.pdf/files/DM00039084.pdf/jcr:content/translations/en.DM00039084.pdf    
  23. dipCoreF4 and dipBoardF4, a compact Core.

    Hey Bruno, I'd like to connect another USB device (mouse or midi controller) to my core. :-) Like in your video...
  24. dipCoreF4 and dipBoardF4, a compact Core.

    Hello Chris, Which feature do you need? Best Bruno
  25. dipCoreF4 and dipBoardF4, a compact Core.

    @Antichambre I'd like to integrate such feature onto my mainboard. Are you willing to share the schematics and if necessary the code?  Any feedback is very appreciated. Thanks! Chris
  26. I’ve just managed to get this configuration to work. I ended up using Midi-Ox to send the CCs you listed about as I couldn’t get it to work using the MB-SEQ to send the CCs. I picked up a FHX-1 this week so I’ve got 16 CV Outs with the option to add another 48 channels in the future. 
  27. MIDIbox SEQ V4 Release + Feedback

    Hi Thorsten, looks like I have to step one step back or so and eat something. Somehow I am doing it wrong (?). But even with your well written how-to I cant get this to work... hmmm Will try further after I have eaten. Anyway, many thanks to you for your fast programming on the new fw and your help! :) I really appreciate it!! Best Regards, jingo   OK, got it: Live send on the mixer page has to be enabled too... :)
