Usb midi issue with Shuttle Control from Endorphin.es

[Acnorytm]

Hi Mike,
I'll try and give you a hand with this, however it will be important to know a couple more pieces of information first:
1. what is the path of the MIDI that works vs not works (for example WORKS: MIDI in from Keystep Pro, to MRCC Port A out Port D to Shuttle Control out via CV to Whatever Oscillator) the more info I have to understand what could be at play here the better.
2. When you say the notes are playing really low I will need to know if the pitch is just lower but notes still play in tune to each other, or if the output is just some random low note all the time. Like if you tune the oscillator up 3 octaves would it play the right notes?

Hi Jesse.

So I have my Push connected to MRCC via usb (From Push USB-A port into MRCC USB-B / PC port)
I have various synths connected via 5-Pin midi with the routing from PC-1 to output ports 1-6 (this all works perfectly)

My Shuttle System is routed from USB-A on the MRCC to the USB-B port on the Shuttle Control with PC-1 routed to USB-A out
The Shuttle Control module converts midi to cv. The midi cc messages I've mapped work, clock works, the gate signals work sometimes but are not consistent, and the 1v/oct just plays a really low note which doesn't correlate to whats being sent, regardless of the pitch of the oscillators. Even if I play the highest note on Push it's still the same as any other pitch being played
I've tried filtering everything other that notes but have the same issue. Also tried using PC port 2 but same thing

What does work
If I route the midi from Push to MRCC via trs cable.
Connect Shuttle System from USB-B / PC port on MRCC to Shuttle System's USB-A port
Make a routing on MRCC from Input 6 (trs-a) to Output PC-1
Everything works as expected

Also if I plug the Shuttle System in directly to Push via USB (Push USB-A to Shuttle USB-B) everything works

I'd really love to get the shuttle system working from a USB type A port from the MRCC so I can use the PC port on the MRCC for push. (Then I can use MPE from push to hardware synths using different virtual PC ports)

I've attached a photo in case this doesn't make any sense!

Cheers
Mike
