Midi -> CV issues

Hermod+
1

I’ve just started playing around with my new Hermod+. I’ve updated to 2.02. I am able to generate notes and have them play out to my eurorack modules via CV and gate outs.

I am able to get the Hermod+ to sync with my Bitwig transport in either direction, but I am having a hell of a time trying to get midi keyboard notes to convert to CV and gate.

I am able to see midi messages from my Roli Seaboard M when using the trs port. Strangely, when I use the USB host port, the Hermod+ will tell me that it sees I have plugged in the keyboard, and it can print to the screen that it is a Seaboard device, but no midi messages from the USB port. The transport sync works over USB, but no notes.

Using the TRS ports on the Roli and Hermod+ can send midi messages that show up in the messages view, but no notes will play through to the CV and gate outs for that channel.

I can use the midi thru settings to send notes from TRS through the device port out to Bitwig and play synths from Bitwig, but no CV routing.

I feel like I’m missing something simple, but there’s no details that I could find in the manual about setting up a midi keyboard and it seems like something that should “just work.”. Any ideas?

Interestingly, I am able to route the midi TRS through the device port to Bitwig and back, and those notes will convert to CV, but not directly from TRS to CV.

Hi,

Could it be that your Seaboard is still in MPE mode ?
If so, it would never send note messages to channel 0, which is the default listening channel on TR1 for instance. If you set INPUT CHANNEL of track 1 to say channel 3, it might trigger once every 15 notes.

Frankly, I’m not even sure the Seaboard can act as a regular single-channel MIDI keyboard, so if that’s the case, currently you’ll have a hard time using it with Hermod+.
I’ll talk with the team so that we add a “ALL” input channel for such cases.

Hi Thibault,

After a bit more fiddling, I was able to learn that the Seaboard does have a single channel mode. In that mode, I can send notes out to the CV via the midi TRS input on the Hermod+, but in the same mode, the USB connection appears to receive no messages.

That should not be the case… I’ll look into this in more detail.
My apologies for the inconvenience.
