  1. Maybe you can dual boot into or start a virtual machine of a lightweight Windows XP environment? I know it sucks for most Mac users, but still loving Rutgers Patch librarian here :)
  2. +1 on Imp´s words - Great job, especially the inking :)
  3. Thanks, Lamouette - the track position display just shows which of the 16 tracks of the mbseq is currently playing (not muted) and at which step relative to the length of the track it is... Ilmenator is currently designing a PCB for it, an enlarged version (with two 8x8 LED matrices) :-D Many Greets, Peter
  4. Hi Simon, bad to hear that, but good that you worked it out :) Many greets, Peter
  5. Don´t wait, it will probably be a good while - and as m00dawg said, most likely some components will be reusable... Personally, I am hoping for the ability to chain two (slightly modified) MB6582 baseboards to one LPC17 controller core to achieve a 16-SID polyphony :) And my hope would be, that the MB6582 CS can be reused in conjunction with a new graphical display... Whatever TK. develops, it will be very time-intensive... Many greets, Peter
  6. You have four MBSID V2 engines at your disposal, and can switch the control surface to work on one or up to four engines at once. Each engine in "Lead Engine" mode is capable of playing on one MIDI channel (or sharing it with other engines for polyphony, "SuperPoly" mode) Each engine in "Poly" Mode is capable of playing on up to six MIDI channels, so you can saturate the available 16 MIDI channels nicely - it is all configured in the ensemble and is recallable easily... Did I ever mention how awesome the MB6582 is? ;-) Many greets, Peter
  7. Humm, apart from what appears to be an optocoupler (the white sharp ic) and an inverter ic (74ls05), theres no hidden gold on the PCB... But you can recycle the box, the cable and the MIDI ports, just cut the traces and solder wires directly to the pins on the backside, might come in handy for a future MIDIbox project of yours :) Many greets, Peter
  8. Using it in lead-engine mode will result in "only" four channels of stereo polyphony... But unbelievably awesome four channels, these are... :-D So, 8 SIDs are no overkill at all, and there is at least one MIDIboxer around here, who has built two MB6582, one with the 6581 classics, the other with 8580/6582... :) Many greets, Peter
  9. Ok. i hope it works, i have not checked the pin arrangement for this socket, and if it is "only one pin more" - if the pins are all in different places, my suggestion clearly sucks, better check before :) Many greets, Peter
  10. Hm, dunno - i´ve only tested the CV1 input for the filter frequency, which worked very nicely even for high LFO rates... With a bit of experimentation it should be doable to create a CV input for Q... Hehe, also just found this thread where MIDIbox forum member sneakthief writes about his Polivoks build - small world :) http://www.electro-music.com/forum/post-267945.html Many greets, Peter
  11. Interesting, Reichelt does not have the 7-pin variant in shop :) But you might be able to use this 8-pin socket in conjunction with normal 7-pin plugs and clip off the 8-th pin before soldering it on the PCB: http://www.reichelt.de/Diodeneinbaubuchsen/MABP-8SN/3//index.html?ACTION=3&GROUPID=5182&ARTICLE=11181&SHOW=1&START=0&OFFSET=16& If you don´t need a PCB-solderable 7-pin DIN socket, i can highly recommend these http://www.reichelt.de/Diodeneinbaubuchsen/DIO-70S-EMS/3//index.html?ACTION=3&GROUPID=5182&ARTICLE=46281&SHOW=1&START=0&OFFSET=16& in conjunction with the corresponding screw-plugs - epic contact, really good quality :) Many greets, Peter
  12. You need a male 7-pin DIN plug - the pinout is here: http://www.allpinout...64_Power_Supply And here is a link to the corresponding item on Reichelt, but you can surely get it in the Mouser/Digikey stores, too :) http://www.reichelt....0&ARTICLE=11201 Many greets, Peter
  13. You can quite easily bring down +15V/0/-15V to +12V/0/-12V with Vregs or diodes, so it is the more universal supply, yes... Also most modular modules use it as a standard, so it is ok to build one like that :) Regarding analog delays, got one on my build list, will start it, after the summer is gone... (it is fully analog, no midi dealy sync trickery, though, but it is nice to dial in slightly-off-sync delays anyways :)) After listening to many demos and comparisons, i decided their sound really beats the digital delays, but there are also substantial differences between fully analog delays - more info Many greets, Peter
  14. Really nice, well done! Many greets, Peter
  15. Hey there, it is this design: http://m.bareille.fr...cf_polivoks.htm In the clone schematics, some opamps miss the +15v/-15v supply, but it is clear that they need them just as the others, so no problem in building it :-). I also used a 10uF tantal instead of 1uF on C6 (low-pass filter section), after a bit of testing I liked it best. Btw. a +12v/-12v bipolar supply should work, too, so you can reuse any MBFM PSU... there is no high current draw... I really think, it would fit great with the gameboy sound or any other rather lo-fi sound source such as the NES, too - just add a nice delay pedal after it, and you are good to go... :-) Many greets, Peter
  16. Thanks, J! And thanks for spoiling me with moar module suggestions :-) ! Heheh, not at all - the Polivoks was a great tip!. I´ve put the PS-3100 on the watchlist! :-). Have a good time! Peter
  17. No problem, should be quite easy to make it configurable... To use the second color of the led matrices, another eight pins per LED matrix are necessary, right? So the whole board would have to contain 8 (2 for bpm/step digits, 3 per led matrix) dout shift registers and one din shift register for bpm control and the additional four buttons? Might just fit with smd components, but it may get a bit tight on there, but i´d also prefer it integrated (with no external DIN/DOUT modules necessary), if possible on a single board :). If you design it, maybe you could provide support for a "pushable" encoder to accelerate bpm entry? It makes a lot of difference on my veroboard seq cs, you can very slowly change bpm by 0.1 increments when not pushed, and by 1-3 bpm increments, when pushed. On a second thought, it would be perfect to have the push function jumpered and either connected to the local DIN shift register, or via a break-out cable to an external "push-to-accellerate" bus, since that feature also currently can be only configured to be on one DIN pin and the gp-encoders need to be push-acceleratable as well... Sorry for flooding you with inputs :) Many greets and thanks for your efforts! Peter
  18. Thanks Antonio, the Polivoks filter was originally recommended by Jojjelito and its characteristics fit really well with the SID sound, maybe even more with your 6581-based even more dirty MB6582 :) Filtering bass sounds with quite closed filter but fairly high resonance is nothing short of spectacular :D ! Many greets! Peter
  19. Thanks! :-) It is a stereo build - a little bit imperfect, because the stereo potentiometers do not deliver the exact same resistance at every pot position, but that only adds to the charme of the filter :-). It is easy to build and the components are really cheap... it might sound even a little bit more raw, if you can source the original russian parts from somewhere :-). Many greets! Peter
  20. No, unfortunately it has found its final resting place somewhere 2000 meters high (later flight)... a fine spot for a fine plane... but I don´t want to do that again, if possible :)
  21. Thanks! The lost friend was the fpv-plane used in these videos - probably caused by a pilot error after an adrenaline rush ;) Many greets, Peter
  22. Hola, here is some Polivoks + MB6582 live action :) (SIDs start at 00:50). That filter nicely increases the rawness of the SID sounds, a highly recommended build and quite cheap (google bareille polivoks schematics!). (also some flying close to the limits in the bavarian alps, what a fun day it was :D) Many greets and thanks for listening! Peter
  23. Great! Ofc I will pay for the board(s)! So you want the full-blown version? Duo color and 16x8? I´d be very tempted to align the tpd horizontally in this "wide" display configuration... so that it looks like 11111111|99999999 22222222|AAAAAAAA 33333333|BBBBBBBB ... Where 1 equals the track position leds for track 1, A for 10 and so on... The LEDs would start to light up in the middle and then "flow" outwards - should be a nice effect :) Many greets, Peter
  24. Hola, sorry for the missing schems and the improved adventure level of this small seq hw subproject :-). Wiring is not difficult: For the 8x8 TPD you need one DOUT shift register for the cathodes of the 8x8 matrix (for single color usage) and one DOUT shift register for the anodes... so 8x8 = 64 LEDs can be switched. For the BPM/STEP LEDs there already exists a schem for the SEQV3 somewhere... verbally, you need one shift register for the common part of the LED digits (say anodes), which connects to each individual digit and thus selects the digit in the matrix output cycle (up to eight digits possible, but only 4 for the tempo and 3 for the step counter are used right now). The other shift register goes to the seven segment positions and the decimal dot of every digit. I´ve directly fed the LEDs, because even with 50R resistors they were a bit dim - they are pulsed at a high rate which causes the average current per led to be low enough - everything is still alive in my setup, after lots of use :-). Ilmenator: great to read that! Regarding multi-color LED matrices (mine are duo-color too, but was out of shift registers :-)) - it would be nice to indicate the currently active track and make it red instead of green! If somebody creates an integrated board for a 8x8 or 16x8 duocolor matrix (many shift registers needed!) including step counter and bpm, i´d gladly write the updated code for it - local testing would be beneficial (so send me one, hehehe :-)) - i would totally love to have it in the portable SEQ on my build list. Many greets, Peter
  25. It looks very nice now! Thanks for your work and sharing the Eagle-files! Best of luck with etching and testing! Bye, Peter
