Thanks for the information! Great news!

I don't have any "social media" account so I will not check IG.

Could you elaborate further on the optocoupler? How do you connect it?

It does internally because of the modern chips it uses (3.3V).

But the front end CV inputs are specified in the manual:
  • • GATE takes "any" voltage and clips it to +5V
    • PITCH takes from 0 to +6V, 1V per octave

Volca Modular CV in: pitch drift

Hello All, trying to make my Arturia Beatstep Pro control my Volca Modular. I've attenuated the GATE signal (13V from the Arturia down to 6.5V) to make it less aggressive on the Volca, and this works fine. The problem is with pitch. I've made measurments, and the output voltages form the Arturia are ...

You can add a random checksum byte (between 00 and E9) with any hex-editor right before the F7-byte and it will be useable with dexed. Dexed does not care if the checksum is right. Hah! Pretty cool, thanks! Will try and let you guys know how it rolls. . It must be the interface itself who loses ...

Hey OpAmp, thanks for your nice reply. 163 bytes would indeed be the size of one SysEx message. And the first 6 bytes and last byte look ok to me. Oh I need to read about SysEx. But are all SysEx messages 163 bytes? Also, do you think that the export "all programs" on the Volca (as in sending all ...

All right okay all right. I hadn't thought that Dexed was listening to incoming sysex at any given moment. I thought the flow was 1. capture sysex with appropriate software and 2. open saved *.syx file in Dexed. Well it isn't so. You can do it in Dexed directly. It's worth noting that you don't need ...

Volca FM MIDI out mod: weird sysex output

Hi all. This is a double post, here and on reddit . User ndstudio describes the mod and how to extract patch data. I'm having trouble. I have done the mod and monitored the output with Midi-OX (filtered out clock messages). It's inconsistent at best. Exporting a patch sometimes outputs a 163 byte ...

I'm going to further emphasize the question: how do you send CCs greater than 127? I'm not your MIDI doctor, but in 20 years I've never heard of CCs over 127. Exotic!

Yeah, well, I'm giving up. Looking at Korg's update WAV amplitude, I've tried several recording levels. Also several sample resolutions up to 88200Hz. To no avail. It always fails in a few seconds. Either it's impossible to accomplish or I miss something. Anyway if someone manages to do this, please ...

Hey OpAmp! Yep, I've cracked mine open to check MIDI-modability and, I have to say there's not much in there. So you must be right. Which is good because it would confirm the firmware-fixable nature of the fault. Plus, I've learnt a little bit more about the differences between analog and digital ...
