  • It might be better to do your own adjustments, it might take some attempts to get it right. I'm pretty stressed out until after the weekend, maybe then I can show you how to roll your own. If I forget to get back, feel free to ask again

  • Ok, maybe you (like me) soldered R21 in the small hole that's supposed to be under the resistor instead of the correct larger hole. That's why my trigger out wasn't working, at least (if I remember correctly)...

  • My hacked firmware is here: https://dl.dropboxusercontent.com/u/4343030/penrose.wav If your hardware is not off by the same as mine, you have to modify the quantizer.c, but you can try with my values first, maybe it's just right :-) To update, you …

  • Ok, thanks, maybe it ok then. I left it singing fof a couple of hours today, no magic smoke...

  • Ok, being a sofware-kind-of-guy, I tried scaling the input in software, by inserting  input = input * 0.98; in line121 of quantizer.c (first thing in quantizeValue). Seems to work perfectly. But before I go on with my life, I'd like to get a comment…

  • I should note that 1) the voltage regulator get's pretty hot and 2) I accidently soldered R21 in the smallish hole under the resistor, I don't know if this could have blown something up that's causing the current problem Regarding nOrd's suggesting …

  • Still struggling with my penrose. Here are voltages in + out of penrose, all notes enabled:     BSP   PenroseC   0.00  0.00C#  0.08  0.07D   0.16  0.15D#  0.25  0.24E   0.33  0.34F   0.41  0.41F#  0.50  0.48G   0.58  0.57G#  0.66  0.67A   0.74  0.74…

  • Unfortunately you cannot measure resistors when soldered. Check the color codes instead...

  • Gate issue fixed, R21 was soldered wrong. Output scaling problem persists...

  • Ok, back with my meter, somethings definitely wrong. But maybe the problem is somewhere else. Here are the voltages of BSP in 8 octaves and the corresponding voltages from penrose out (only C enabled): BSP   PENROSE0.00   0.000.99   1.001.99   2.002…

  • I'm away from my modular ATM, but still: 1) I was informed that the R21 mod was unnecessary on PCB 0.4 (which I have). Also the problem is not that the gates are not strong enough, but that they appear at wrong places. On video 3 in my first post, y…

  • Thanks the the reply! 1) so somethings wrong here 2) ok, strange but I'll accept that 3) the BSP and cvpal checks out ok according to my multi meter. No calibration possible here. Seems like Penrose input is wrong. So any ideas where to start …
