  1. And the final SEQ v4+ case! :)

    From the album Hawkeyes MB stuff

    This one uses a left-hand jog and activity matrix configuration, with green/red ("emerald green") color scheme! :) Enjoy and many greets! Peter
  2. Yesterday, I finished my MBSEQ V4 build. I decided on the following components for my version of the sequencer. STM32F4CORE MBSEQ CS: Wilba Control Surface BLM16x4: 16 x 4 button matrix TPD: Track Position Display 2 x MIDI I/O: MIDI interface, a total of 4 MIDI IN and 4 MIDI OUT DOUTX4: 4 x 8 digital outputs AOUT_NG: 8 CV outputs (1V/oct) I did think about placing the digital outs and CV out modules outside of the main sequencer using line drivers so the sequencer did not have to be near the modular synthesizer. I did test the configuration and it worked as it should. However, I decided against it as I wanted the sequencer to be a self contained unit with all functionality in one box. The diagram below shows that final configuration with connections between the modules. I started with the main panel. As I wanted to house the sequencer in a 19? rack case, all panels are compatible with the standard 19? rack dimensions. I downloaded a Front Panel Designer panel design from the Midibox forum and added studs to make mounting the control surface PCB and LCD’s a lot easier. Here is my version of the FPD file: mbseq_19in_io-v01.fpd Here is a picture of how the PCB's are mounted to the panel. The second panel contains the BLM16x4 and TPD modules. For this panel I also added studs to an existing design to make assembly of the panel much easier. And here is my version of the FPD file: TPDBLM_19_v02.fpd The third and last panel holds all input and output connectors. This is a custom panel designed by myself. All I/O PCB’s are mounted directly to the panel except for the DOUTX4 PCB which is mounted in the rack case and connected to the panel connectors with flat cables. The panel also provides 2 USB +5V connectors for connecting LED lights or other peripherals. The other 2 USB connectors connect to the core PCB and provide a way to upgrade the core board firmware and the MBSEQ firmware. If I had to do it again I would leave out the labels above the SYNC outputs. This is the FPD file for the panel: MBSEQ_IO_panel_2HE-v02.fpd For the case I ordered the Thon Rack Case 8U 12 RA from Thomann. My MBSEQ V4 fits perfectly in there. There is even about 1 HE left. I used a black panel to fill that space. On the bottom of the case I mounted the core module and the DOUTX4 digital out modules. I also installed a custom PSU (DC-DC converter) which provides +5V (for the core board and the USB ports on the I/O panel) and +12V/-12V (for the AOUT_NG module). I’m very happy with the end result. The panels fit neatly in the 19? case. The 19? rack in the case is a bit angled which improves visibilty of all display and controls. Here is the final result.
  3. Analogia

    Yo folks, no time for anything (the little one keeps us well-occupied), just dropping by to wish a happy midsummer time to all northern friends ;-) and to dump some (mostly) analog output to the forums ;-). It may sound a little melancholic, that's the feeling i sometimes get from such perfect summer days. Good to see some new developments on the MBSEQ and Core front happening, keep it up! Enjoy and many greets! Peter
  4. Going Up

    Hola, it has been a while, but times have been busy :-) ...finally found a use for that dust-gathering Virus C :-) (its vocoder really is not half bad ;-))   Thanks for watching and listening! Peter
  5. SID Love

    No time for anything (sorry, Andy :-)) but the occasional MBSEQ jam ;-) Big thanks to Shuriken for providing the Anushri boards, what a great little synth! Have a relaxed winter season and thanks for watching and listening! Peter
  6. Fuel!

    Yo, in case i did not mention it during the last months: the MIDIbox sequencer is awesome! It allows you to flee reality (baby teething worries) for as little as half an hour and have fun, without pushing a mouse, without staring into a computer screen or getting involved in operating system updates at unpleasant times :-). It just works out of the box, the MIDI timing is way better than that of a multi-GHz multicore computer and everyone is happy with as little as 128kb ram (in the older cores)! :-) This one contains a few fun samples from an old car information system - 1980s era - and reminds me of childhood - i especially love the modulation on the "door is *open*" sample :-). Yes, bash it, hate it, do whatever, but thanks for watching and listening ;-). Have a great evening! Peter  
  7. Hola,   it has been a while since the last photo tutorials - I really wanted to do this for some time, but there was always work or some other distraction... but now, there is some time to spend at the solder station :smile:.   This will be a documented one-time build for a MIDIbox member, who is an industrial designer and wants to create his own MBSEQ enclosure and frontpanel (thus the non-standard control surface LEDs). Am very eager to see the end result :-).   Each step will be photo-documented and contain parts lists, where possible - hope you enjoy the build documentation and that it may be some help to other people wanting to build a MBSEQ, who may yet be intimidated by the amount of parts necessary, the soldering or the software configuration.   I will try to structure this tutorial in such a way, that progress is quickly visible - and that you do not need to assemble everything before "turning it on" the first time. The faster some progress is visible, the higher the motivation to continue building... :-)   The MBSEQ is the most awesome piece of music gear, that I own - many thanks to TK. and Wilba, who made it possible!   Enough talk, let´s get started :-)   Many greets, Peter   Here are links to other existing photo tutorials: Custom SEQ V4 (DIY control surface, VFDs, ebony wood carrier):   MB6582 Control Surface:
  8. Hardware Synthetic

    Hola, it has been a while, but here is a new one, made during one of the recent sleepless nights! ;-) The MBSEQ is awesome for relaxation! Even if the track is probably rather mediocre due to lack of sleep and stuff, but anyways, these are happy days! :-) Thanks for watching and listening and have a great time! Peter
  9. Happiness is Analog :-)

    Yo folks, not lotsa time to spare at the moment, but some keyboard time is necessary after work :). Also as promised long ago, here is finally the successor of "Hill Diver part one" :). Hope you like it and as always: thanks for watching and listening! :-) Many greets, Peter  
  10. Hello   I want to finish my mbseq V4 with the new core STM32F4 i m not sure that i need 4 midi input so i wanted to know if i could used the quad IIC midi board with the STM32F4 for have 2 input midi and 6 midi output and the BLM output (2 input and 2 output midi come from midi I/O board for STM32F4)   Zephyrin

    Hola,   just in time for the weekend, a new live MBSEQ V4 session and a multicolor vector voyage! :-D   http://youtu.be/c1HnoE4Rh5I   Hope you enjoy and thanks for watching and listening! Peter
