Hi all,
after firmware upgrade my Volka Modular is not able to correctly boot anymore. When the power up button is pressed, Attack/Shape/Release/Time/Fold controls led turn on but then nothing else happens.
Does anyone have an idea about how to solve this issue? Thanks
Here's few pictures:

Re: Modular not working anymore after upgrade
Hi, did you even tried to reflash firmware again? With computer/OS sounds turned off and play source volcamodular_sys_0108.wav loudly with all possible sound FX (eq, bassboost, reverb etc.) also off? Another suggest is to play source *.wav from another source than computer (music player, mobile device, whatever).
Digitakt, ER-1, Volca Beats + Bass + Modular, Neutron, k-2, Microfreak, Liven XFM, Beatstep Pro, Keystep, UC-33e, few FX (Zoom G1four, Razzor DD+DS, EHX Platform+HolyStain, Samson C.com), Mackie 1202 VLZ4, pair of RCF AyraPro6

In my case it will no longer enter update mode. This happened after
trying to update it unsuccessfully a number of times.

OK, then you can try to contact your nearest Korg service, better authorized, if you didn't yet. I guess that your unit needs to reset the chip and load healthy bootloader, then firmware, and they could be able to do it.uddhava wrote:Hello, thanks for the reply.otzcz wrote:Hi, did you even tried to reflash firmware again?

But, at 1st place - it needs proper diagnostic. I have service manual for V.Bass (it's online, you can google it), it's includes few diagnostic methods, I guess some of them are useful for all Volcas, so you can try it, if you want. My presume is that all volcas are built around the same Microcontroller: Toshiba TMPM330FWFG (it makes no sense, if not), the datasheet and user manual for it is online also, so you can study

If you will not find them, let me know, I can upload them somewhere.
