  1. This is my fourth or fifth unsucsessful attempt for last half-year to calibrate AOUT_LC module. Yesterday i've replaced R49/51 with 100k ones and get perfect calibration for 1V, 2V and 4V values. But i have 11,22 instead of 8V. Or 0/11,22/11,22 with Min/Mid/Max Replaced opamps, shift registers, checked all resistors and here what i have. (1 - Vdd 4,95v) I was confused by one point - why there's non linear value of 4,32v at 8V calibration setting. Is it R-2R related? I measured resistance between shift register outs and opamp inputs. Is it looks acceptably? Shift register? I replaced it three times with different suppliers ones. Or maybe it's software related? I'm totally confused and need your help. PS. Bipolar supply values is +11,87/-11,97

      around 300ms. The weight component also has a fast attack but longer decay, so we have time to feel those low frequencies.

      for FM algorithm heaven, have a look at the FS1R - not understandable by mere humans, though :)

  8. Friend of mine brought me two broken Alesis SR-16's to make one working from them. Repaired both. Now one is mine. Sounds excellent, but not for electronic music =)

      Nice! There's always great satisfaction tied together with surgery like that :D

  9. I'm about source, actually. That shop has this chip too. http://www.utsource.net/YM3812.html
  10. Do the electronic components has a karma? If so - OPL3 and SID's has a good one! :twitch:
  11. It's an irony. 2nd life of electronic components is good!
  12. UTSource: Mininmum order - $10 YMF262-M - $3 YAC512-M - $3 International registered shipping - $4 Stop cannibalizing soundcards! :frantics:
  13. In old tutorial you wrote, that this cant't played by real drummer, so i think MBFM can. Now everything is clear. Thank you, Torsten!
  14. Firmware update is the first thing i did. The bug, i've described occurs on 1.4d =(
  15. I think this topic should be moved to MIDIbox SEQ forum. :getlost: The HiHat question still opened.
  16. Hehe, sometimes problems have to be formulated in writing. Yes, it's low voltage related. I've look to schematics of Midipal (3.3 v midiout too) and removed/replaced 220 ohm resistors at all outs like schematic. Now all works fine, but with a little bug (or feature?) - opened and closed HH can't play simultaneously. Is it OPL3 restrictions or smth wrong with my MBFM? for example in this case OH somtimes triggered, sometimes not. It's random alike thing. OH ....*.......*... CH *...*...*...*... But when there's no overlapping between them - they played correctly. OH ....*.......*... CH *.......*.......
