no i mean use the hex file, chat is better for this kinda thing...

just use hex file upload

you should also upload the app from mios studio...

B (the one that is a straight line) (note that not all manufacturers use the same letters)

woohoo, coolness!

akk, if you had random data coming into the analog ins while uploading mios, you might have messed up the pic. i haven't had this happen myself, but several folks have reported similar issues in the chat. even if this is the case, you might still be able to save it. maybe someone who has done it can give you the magic reset formula. or you could try reburning the bootloader a few times, and then make sure analog ins are grounded while uploading... (hehe, hmmmmmmmm the 1k pots weren't the issue, who woulda thunk it? *whack*)

check out the ainx4 module for the drawbars http://www.ucapps.de/mbhp_ain.html

i did this with 100, very very precise. at the temperature when i did it. erm, plus hand temp etc ok, so i'm crazy...

Thanks so much for this link! I have needed a psudoacoustic processor for doorstop applications for years, finally rane comes through!

guys, i copyrighted this years ago as evidenced by this copyright notice: see???!

sorry, equal temperament is notes at 12 equal divisions of each octave. you mentioned 1/4 tones, which (if equal) would be 24 divisions of each octave. hope that helps... on the other hand: a good point, is there a standard mapping or is each synth that supports it using their own?

"you know, it was like a drunken monkey, you know, on the piano, trying to play the blue danube or something, you know" oh, i know... good stuff!

looks at first glance like equal temperament is built into the code...

there's a female contingent?? cool, which member is it?

hmm could it be you had the joysticks wired wrong?

correct. even better, this should result in less than 100mA total draw. i think you are ok with only 12 1k pots, more would be no good though...

this is the normal series for 1k pots parallel resistance for equal resistors is Rp = R/N, where N is the number of resistors in parallel. this total is in parallel with 4k so = 1/(1/4000 + 1/Rp) you should wind up with ~60 ohms in total with 16 (assuming the joysticks are also 1k)

ok sounds like the srio test passed to me. only thing left is to check continuity along the SI path, and also check that it is not shorted to Vss or Vdd. if that's ok, then you do probably have some bad 165s, these are cmos and so are static sensitive. were they shipped in static protective bags? did you handle them while/after walking on carpet or like such as? soldering while they are stuffed without a esd safe iron? i use a grounded wrist strap while handling cmos, def worth the $5 investment...

measuring this way was correct, and the result indicates a short somewhere. to find it, first check the with the ain module connected and no pots, then add 1 pot at a time and measure the same way. measuring v works too, but since you are overloading the vreg, better to test for short with ohmmeter or continuity tester

ok, but remember if you use tubes that carbon composition 0 ohm resistors sound warmer. and if you can't get those in better than 1% tolerance, just measure each one and make sure it is closer than 1% of 0 ohms, (i prefer to be within 0.001% of 0, but that's too perfectionist for most folks)

for audiophile quality, you must harvest cut resistor leads only from 0 ohm resistors! measure them first to make sure they are not counterfeit...

no, this only tells you the buttons and their connecting tissue are working, next you move downstream... as stryd suggested, you should do the srio test several ways, core only, measurements at core with 1 dinx4 attached, measurements at dinx4 j1, measurements at the din chips themselves somewhere along there i suspect you will find that it fails. post detailed results... this only matters if you are connecting both dout and din on the same chain. ok, you obviously need a working core first...

agreed. the customizable nature of midibox is one of it's best features. but i think in these cases it is better if the hardware is consistent, since it will be easier to troubleshoot, maintain, manage software upgrades, etc

have you done the srio test? if that passes, check v at the din pin for each button both when pressed and unpressed (should be Vdd when unpressed and 0 when pressed)

ok, i will do then. i will also lay out a 2x4, since this would be more generally useful. coolness, even better then. especially for enable buttons, this is more than good enough
