Hola, it has been a (too) long time, but now, finally: introducing midiphy zetaSID, a eurorack-based take on TK.'s fantastic sound engine. @TK. also did some testing and helped with a code tweak - thanks a lot for that! Here's the release video: And a great SID tune made by SID sorceress Avrilcadabra: And - best of all - we have a free web emulator of nearly the whole engine - which can also be tested via a MIDI keyboard: https://www.midiphy.com/en/zetasid-emulator/ There's also an advanced web-based patch editor (similar to Ctrlr with a few additional graphical bells and whistles): https://www.midiphy.com/en/zetasid-webedit/ More information can be found here: https://www.midiphy.com/en/zetasid/ As it is (mostly) patch compatible with the MB6582 Lead and Drum engine, it should be possible to load your old patches and enjoy them on your modular system. Hope you enjoy! Best regards, Peter

absolutely! :) Best regards, Peter

sorry for my stupid question, i was long time out of order, is this version also for v4+ version of the Midibox v4 ? Thanks a lot and br Cit

latest build. with custom PSU - DC-DC for less noise and bleed. ARMSID x6 , 8580 x2

Hi, I might have what you're looking for. Would you be interested with original 2044 chips too? edit: found, PCBs from Seppoman and chips from Wilba

HI Folks. Returning to projects after a long time away, I seem to have lost 3 unpopulated boards for this project.. I had one built and tested, but then found what I thought was a tube of 6 2044 chips were actualy CEM3394s. I have found a workaround using the SSI2188 and an adapter board and want to finish the filter bank I began years ago. So - does anybody have any boards they woudl like to parts with? Thanks.

Hi, Is it still available ? Best regards Manuel

Hi FantomXR, do you still sell them? Thanks, Tilmann

Dear all, I'm cleaning up my lab and i've found a box of about 100pcs 50kOhm double faders that i purchased long ago for a Midibox project. I have to admit i'll be very sad to send them as scrap, as they are very high quality... Whoever needs them let me know, not planning to make any money out of it, just cover shipping expenses (from Italy) and whatever you feel right to pay for them

Single +12V (not ~12V as on original) can be used, and it is included in the package. 12VAC is probably also supported but I do not have an appropriate power source.

Does it require the original twin power supply or is it running off a normal 12v supply? I imagine I would have to source it myself? thankyou

Hello and thank you for the interest. They can be mixed on the main PCB, so you just choose the voltage for each SID installed. Proper capacitors should be installed as well, I can arrange it before shipping. Default capacitors are set to 8580 mode. You can set the voltage separately to each of 8 SIDs, just like on original MB6582.

Sorry I should have clearer,could I have (for example) 4x12v and 4x9v Sid's in the unit? Not trying to be awkward but that's what I have here...4 of each.

Do these units cater for 12 and 9volt Sid's like the original?

Yeah, I know, I’m like six years late to the conversation, but… I was looking into the ESP32 myself recently, but for an entirely different purpose. From what I understand, there are two hardware UARTs on the ESP32 that can be accessed on the dev kit v1 board. I have further come to understand that the device can be configured as an i2c slave with a configurable address using the Arduino IDE and the wire library. My thought is this: configure the ESP32 as an i2c slave to provide 2 DIN MIDI outs (plus perhaps Bluetooth MIDI) to my stm32 based MIDIBox sequencer build, in opposition to the PIC-based i2c MIDI solution, as it is getting harder and harder to program PICs in the modern age. Does this sound like it could be a feasible solution, TK?

Hi @Wilba, I have finished my build of the MB6582 and would like to have a serial-number to be able to officially finished this project. I tried to login here at the builder_list site with my credential from this forum I get an error. Is I could not see "sign in" button I wonder how I can connect my forums accounts? Thanks!

Hello, I hope someone can help me. I am trying to have 3 different layers of sound generated with 1 physical keyboard. I.e play piano with strings :) I have 2 physical keybeds Keyboard= 1 and Keyboard= 2 Each of them is assigned to 3 different channels on different output ports. When I play one key I have desired result only on first press. I.e press note C and it plays on 3 different channels. On second press I have three notes generated but all on the same channel. Here is my config file: # KEYBOARD hardware KEYBOARD n=1 rows=16 dout_sr1=1 dout_sr2=2 din_sr1=1 din_sr2=0 din_inverted=0 break_inverted=0 din_key_offset=32 \ make_debounced=1 break_is_make=0 \ scan_velocity=1 scan_optimized=0 note_offset=36 \ delay_fastest=5 delay_fastest_black_keys=0 delay_slowest=100 EVENT_KB id= 11 hw_id= 1 type=NoteOn chn=1 key=any use_key_number=1 range=0:127 ports=00010000000000000000 EVENT_KB id= 15 hw_id= 1 type=NoteOn chn=4 key=any use_key_number=1 range=0:127 ports=10000000000000000000 EVENT_KB id= 16 hw_id= 1 type=NoteOn chn=5 key=any use_key_number=1 range=0:127 ports=10000000000000000000 KEYBOARD n=2 rows=16 dout_sr1=3 dout_sr2=4 din_sr1=3 din_sr2=0 din_inverted=0 break_inverted=0 din_key_offset=32 \ make_debounced=1 break_is_make=0 \ scan_velocity=1 scan_optimized=0 note_offset=48 \ delay_fastest=5 delay_fastest_black_keys=0 delay_slowest=100 EVENT_KB id = 12 hw_id= 2 type=NoteOn chn= 1 key=any use_key_number=1 range=0:127 ports=10000000000000000000 EVENT_KB id = 13 hw_id= 2 type=NoteOn chn= 2 key=any use_key_number=1 range=0:127 ports=10000000000000000000 EVENT_KB id = 14 hw_id= 2 type=NoteOn chn= 3 key=any use_key_number=1 range=0:127 ports=10000000000000000000 Here is what I see on Mios Studio.

Anyone can help me understanding what is wrong?? Regards, Bartosz

Good news everybody! I got my OLED displays working!! The displays in question are Focus LCDs 0402A-CW-SW3, I ended up downloading the mios tools from GitHub: https://github.com/midibox/mios32 And the mios toolchain for macOS here: http://www.ucapps.de/mios32_c.html And compiled the bootloader updater make file at: ./mios32/bootloader/updater Uploading the resulting .hex file now included the lcd_type 0x02:CLCD_PP which allows the LCDs to behave properly. They were working with the lcd_type 0x01:CLCD_DOG but that configuration was not handling the line break correctly. Basically, after setting the clcd_dog option and sending the store command the "Bootloader is up to date! :-)" message was all on one line instead of split between the 2 lines. Now it works as expected. Hopefully this helps the next brave soul that attempts this! :D Here is they are happy in my SEQ V4, pardon my messy desk. XD Thanks everyone and many thanks TK for all your awesome work!!!

I'm upgrading my SEQ v4 with some OLED displays. I was able to get them working by changing lcd_type in the bootloader to 0x01: CLCD_DOG. However, the text is only being written on the top line. I've been trying to troubleshoot this and there is supposed to be a new lcd_type for this display in the boot loader (0x02: CLCD_PPP) but I'n not seeing that option when I run the lcd_types command. Is there a different version of the boot loader that I need? Here is my output from MIOS Studio: [595397.479] Initialize LCD #1 [595397.536] Initialize LCD #2 [595397.592] [595397.592] ==================== [595397.594] Bootloader 1.018 [595397.604] ==================== [595397.607] [595397.618] Checking Bootloader...

Thanks in advance for the help!

Just got in the first set of pcb's i designed for controlling the XV1A synth, nothing over the top some simple one sided pcb's from china, 10 of them for around £8. To get them done in the UK was around £140 excluding vat and delivery which was a shame. Just about 2 weeks delivery from jlc pcb, I am getting a couple of different multi layer ones done after xmas one i finish them in Altium.

Hi everyone, After nearly a decade of silence, we are resuming our project. What once was merely a concept is gradually taking shape as a tangible endeavor, culminating in my son's high school graduation. I shall endeavor to share updates and photographs of the project in the coming weeks. The initiative is based on the Midibox NG platform, complemented by additional software written in Python that operates on the host side. I wonder whether anyone is still engaged with Midibox NG, as the last official version was released in 2018, and the most recent version available on GitHub dates back to 2020. I ask because I will likely have numerous questions, and I wish to share insights and ideas. I regard Midibox NG as an exceptional concept; it would be a shame if it were left unfinished. Best regards, Bartosz

PM sent, thank you :)

Hello and thank you for the interest. Replied to PM and in the MB6582 thread. sammichFM is planned to be optimized in design and I plan a small batch in the new year.
