In all seriousness though, if there’s one thing I’ve seen a lot, in the decades of beta-testing I’ve done, it’s that the exact timing or spacing of general MIDI and MIDI Sysex data can be critical for some devices.
I don’t know, but it seems plausible to me that whatever adjustments the Quadra is making to the data throughput could be tripping up the NINA.
Cheers!
Im not sure this is true, my Polyend play before I sold out worked fine powering my Quadrathru and that was via 3.5mm midi with a little dongle.
Ive used my octatrack with my Quadrathru with other things and it powers the Quadrathru with a blue light.
I believe the Quadrathru takes power from the device going into its midi in jack. Which would be the octatrack in my and your case.
Is your OT a mk2? It should work in terms of sending data and power to the Quadrathru, but I can’t speak for Nina compatibility
The OT was powering the MSQT but I couldn’t sequence the NINA. The NINA was the issue.
So apparently Nina is now MPE capable!
Are there any known bugs on Nina? If not, then the developer team has brought a bug-free product to market and introduced additional functionality in a very short time. This gives me a lot of confidence in the team (especially given how innovative the product is with a lot of complexity due to the motorized knobs)…
Is there a firmware update?
Apparently soon, was showcased at Superbooth!
Has anyone who owns one of these utilised the USB-IN which is class compliant?
Wondering if I can hook something like a Torso T1 sequencer straight into this via USB
I used it with the op1f like this and it worked perfectly. It was a joy!
As in using the op1f to sequence it?
I’ve used it with my MPC Live 2 for a while now. to sequence and program change the Nina. Nothing crazy yet so I don’t know with automation and modulations yet.
Yep! It’s really amazing to sequence with the oxi one as well.
Ah shall try. 
The latest update includes MPE support as well as new effects and multiple effects at a time.
Sounds great! 
What are the new FX. When you click on the link, it gives you the release notes of the previous version. So, a wrong link.
New Features
MPE
• MPE support added.
• MPE has options for Upper or Lower MPE Zone, Pitch Bend range and MIDI CC Polarity.
• MPE works with the 4 multi-timbral layers, so stacked sounds can be MPE controlled, or multiple MPE zones, controllers
or standard MIDI keyboards can be assigned different channels.
• MPE operation has a decay feature for expressive sound control on the MPE axes of Aftertouch and CC74. Hold the KBD
Key down for more than 1 second to silence all voices, and stop the arpeggiator and sequencer.
Effects
• Nina now has 3 effects processors, allowing Chorus, Reverb and Delay to all be used together.
• Any order of these effects is possible, they can be chained in series or in parallel in any combination.
Additional New Features
• Added LFO mode to the wavetable oscillator (OSC3). This moves the wavetable frequency down 10 octaves, making it act
as a third LFO.
• Added ability to import wavetables created by WaveEdit. These are automatically recognised on import.
• Note Release Velocity is now available as a modulation source. This can be selected via the MIDI MOD SOURCE
parameter in the LAYER menu.
• LCD Screen color may be changed.
A selection of colors in available from SYSTEM > GLOBAL PARAMETERS > SYSTEM COLOR.
• Global Master Tune function added. Tune the entire instrument up or down up to 200 cents.
Access via SYSTEM > GLOBAL PARAMETERS->MASTER TUNE.
For 432Hz tuning, use -32 cents.
Please refer to the updated Nina User Manual and/or 1.3.0 Release Notes and Addendum regarding these new features.
(included here on Pages 3-4)
Fixes & improvements
• Internally generated Control Change messages now sent to DIN MIDI (as well as USB).
• LFO to wavetable position not fully scanning some wavetables.
• Booting a unit that loads a Patch with Hard Sync on resulted in no sound.
• Tempo not loaded from a Preset.
• Toggling A/B could cut-off MIDI notes while playing.
• Some types of USB drive formatting caused drive not to be seen.
• Soft clicking with VCA Spin in some cases.
• Soft clicking occurring with some sounds when voice stealing.
• In Windows NINA now appears as ‘Melbourne Instruments NINA USB MIDI’.
• Removed unintended delay between knob movement and the effect on sound. This was noticeable in very fast movements.
Very excited about the fx! Hope they add a couple more variations to each effect as well.
This is really one surprising synth.
To change color of the screen is a very nice and surprising feature.
