  1. true, as long as you don't mind very high notes becoming very low notes, or if transposing down, very low notes becoming very high notes
  2. as tk pointed out to me in this thread , there is a risk of sending invalid midi data when transposing (you want to avoid sending midi data above 0x7F) in my example i just rapped out of range notes around note 0, but for your case you might just want to block them...
  3. i'll trade places w/ wilba, he deserves it and will prolly use them first anywayz
  4. did you adjust the contrast trim pot?
  5. is the decoupling electrolytic cap backward on the 7912 input? the + side should go to gnd (which may be confusing) and the - side to the i 7912 input...
  6. that's what i'm talkin bout! here's my full shot. note the special attention to general tidiness, which ensures successful completion of projects that thing is a great idea, mb-dev_brd... tidy_workspace2.JPG
  7. no slap for you! the caps should go "as close as possible" to the power supply pins on the ic's
  8. 1n4148 is a small signal diode, you want power diodes (1n4001, 1n4002, etc) *slap*
  9. hmmm that image looks like they might be relabeled to me (the text looks too white, pin 1 orientation is not the same). before this becomes an incident of some kind, and with you being so new to the forum, may i suggest that you send some samples to someone with a good reputation here (seppoman, nILS, Wilba...), who can verify the quality? maybe 10 or so, to be paid for after testing, or returned...
  10. i take it you are also confused as to why you posted this in the chat thread...
  11. i would measure current draw on both 9v and 5v regs. also i read somewhere that cascading the regs in this way can cause oscillations, maybe the bypass caps are enough to prevent this, but given your experiences here, maybe not. it may also be more of a problem when the 5v reg supplies more current than the 9v...

  13. like the title says. yes that's the fabled mb-6582 base pcb for those who don't really believe it exists. and yes those are 0.001% tolerance cut resister leads, which i'll sell on ebay someday when their value has doubled enough times... MB-6582_006-tidy.JPG
  14. woohoo! track is nicey, too. me likey
  15. do you still have v1 patches on your bankstick?
  16. i got a fever, and the only prescription is more chat...
  17. measured between regulator input and "gnd" at reg input. should be over 10vdc there. measure vac too, which should be very small
  18. it's 9vac between pins 6 and 7
  19. you mean "advanced sid substitute," right?
  20. hey this is good stuff, almost missed it somehow... reminds me of mommyheads. interesting use of the sid for sure!
