Title: Weirdness with Focusrite Scarlett 6i6 and MIDI Solutions Quadra Thru
Post by: evilgus on September 10, 2020, 04:30:27 AM
Hi folks,

I'm slowly learning my way around my new OB-6, but have experienced some very weird behaviour when connected to my Scarlett 6i6, especially with MIDI In coming via the Quadra Thru. Has anyone else had problems with these devices and the OB?

A few examples:

1. Yesterday, I had both MIDI IN and OUT connected to the Scarlett and the OB was reduced to only 3-note polyphony. Also, playing a patch with the Arp switched on, just didn't behave correctly. You could "add" notes to the arp, but if you then lifted one finger, the arp pattern would stop playing. Luckily, when I pulled the cables, it all returned to normal.

2. Last week, I was trying to sequence the OB from Ableton, so had the Scarlett running through the Quadra Thru to OB MIDI IN. Rather than playing the track, the OB just played random notes and puked up green vomit, LOL. I don't even think I had a MIDI Out cable connected, that time, so just incoming MIDI.

I have to admit I didn't write down exactly what Global settings I had at the time, but I think I turned OFF all Param settings and just had MIDI Control on.

Cheers,

EG

Technically speaking, none of the Focusrite interfaces are listed as being supported by any of those MIDI Solutions boxes. You could try a Kenton instead. I'd start there rather than the OB-6.

1. Sounds like a MIDI loop - so when you press a key you're getting the note from the keyboard and the same note again via the computer, hence you lose half the polyphony, would also give arp weirdness - turning local control to off on the OB-6 is one way of curing this, the other to stop MIDI pass through in the software you're using. Depends on your set up which is the better solution (usually local off).

2. Don't know about this one - could be an issue with MIDI power (does Scarlett supply this? "The 3rd Generation Scarlett range does support Power over MIDI, we have tested and verified this using a MIDI Solution "Quadra Thru" device.") , or dodgy cable, or not quite fully connected....
