just watched you video after my last post.
gave me another idea:
please check r8,r9,r26,r64,r60 pulldown resistors. (especially r9 if you have only u2 and u5 inserted)
if there is something wrong with them (not soldered right or missing), randome …
your 595s look fine to me.
sd card shouldn't matter to the buttons.
crystal is fine i think. if there was a problem there, the whole thing shouldn't boot up at all.
if there are some 165 missing at the end of the serial chain the serial input (pi…
that psu is fine.
so the problem happens when you put in a ic in u6 or u10 no matter which ones of your ics?
would it be possible to get you friend to probe the digital lines of that serrial bus again? maybe put in one ic at a time to narrow the p…
A: no there is not only one, but multiple (127? - not sure) Pattern Sets (and also kits) per Card.
B: save:press "load/save" until it says save.
press encoder so that ">" sign shows up. navigate the ">" sign to edit what to save (patch, kit,…
there is not that much to it.
the buttons have the resistor networks for pulldown. then go to 74hc165 parallel to serrial shift registers which are chained togeter then go directly to the atmega.
with the leds its kind of the other way around : atm…
@implant: some of the stuff is indeed crazy beyond usability, but some stuff is really great. i use my gvs (1bit video sampler) all the time and even build another one from an arduino with his schematics.
not many people are doing video though - …
@julian: nice!
i did a lot of eurorack diy in 2013.
still some troubleshouting to do, but i have a all diy (except braids) modular system now.
@implant: are you aware of gijs giskes stuff? its as weird as it gets..
@julian:
i have a ibook g4 with live 7 which i can reproduce the problem with.
i can lend it to you to sort this out.
i need it until 11.01.14, but after that you can keep it until you sorted out the problem.
we could meet in ffm or i could bring i…
nice
using the amp envolope was exactly what i meant.
i imagine it to be usefull for drums that are not triggered, but use for exapmle an env->vca setup.
nice.
the people over at devsound are also having a "acid december" project again. http://devsound.se/2013/acid-december-2013
so thats plenty of acid for the next two month.
on a related matter:
can anybody name a synth that actually uses note off velocity?. (like vca env release for example) i have never seen it in any modulation matrix or noticed it beeing used.
have a look at the power supply part of a shruthi filter board.
you could hack up something like tsv suggested, on a little bit of pearfboard. but simpler
basically lt1054 and a bunch of caps. depending on your input voltage you don't even need reg…
of course one could always diy a thru box...
for example like this:
http://midisizer.files.wordpress.com/2013/01/midithru.pdf
all it takes is basically a hex inverter, optocouper and a bunch of resistors
i think the PT2399 stuff would be easier done externaly. just build this or something like that.
there is no digital control anyways so whats the benefit of building it inside? you would have to find space and drill holes for extra pots etc...
