I was wondering how I can sync my Sub 37 to the tempo in logic. Specifically the arpeggiator. I am pretty new to music production in general and the sub 37 is my first synth. My current set up is sub37 > scarlett 2i2 > MacBook pro. Do I need midi connections in order for this to work or am I fine with my current set up? Thanks!
Usually best (cleaner) to do this sort of thing via Midi.
Okay great. Thats what I figured… So I will return the scarlett 2i2 for 2i4 and try it again. Thanks!
I think you could just plug the usb out of the sub37 into the macbook and pass midi through there. No need to run it through the audio interface.
I use a USB cable for MIDI and it works just fine. Be sure to set up Logic to send clock to at least the SUB37.
Okay thanks for the replies! I will try when I get home.
Okay I connected it but it is connected as a midi keyboard now to play VST instuments… I wanted the actual sound of the moog to sync up to the tempo in logic . Is this possible?
The USB connection is for MIDI only. MIDI does not transmit audio. Are you aware of this? You may need to do some research on the topic.
Okay I understand thank you for the help but this still doesn’t answer my question. I just would like to know if it is possible to have the sound of the sub 37s arpeggiator to sync up to the tempo in logic?
As stated earlier in the thread, yes.
yes - if you connect the sub 37 to your mac with USB, you can send MIDI clock from Logic to that destination in the project settings synchronization tab. You will need to turn on ‘sync’ in the arp section of your 37. You may find it works better to turn local control off on your sub when you do this sort of thing
Okay thanks I just did everything you said but now I am not getting any sound out of the sub 37 into logic. Please see below for my settings. I am also a little confused as someone stated earlier in this thread that you cannot get audio out of MIDI. Maybe I might not being clear and I apologize as I am pretty new to all of this including the workflow of logic and music making in general. I do not want to use the sub as a midi keyboard for VSTs. I want to play the actual sounds from the sub 37 into logic and sync the arpeggiator from the sub 37 to logic so I can play along to the tempo/drums within logic.
is the logic transport in play (or record)? when the ‘sync’ button is engaged on the sub37 it won’t do anything until it receives midi clock, and logic doesn’t transmit midi clock when it’s stopped
Thank you for all your help! I finally figured it out. Only thing now is I need to figure out why its only coming out of one ear. 
It would be helpful to know what solved your problem for future people that find this forum thread. What was the key to the solution?
The Sub 37 has a mono output. If you recorded on a stereo track, you probably only have audio on either the left or right channel. Try a mono track instead. (Or check the panning setting for the track if it’s already mono.)
Glad you were able to get it running!
it looks like you made a stereo external MIDI plugin and the synth is mono - if it’s plugged into input 1 you’ll only get signal on the left side (the input 1 side of the 1/2 as L/R grouping)
either replace that plugin with the mono version, or you could add the ‘Gain’ audio plugin on that existing strip and hit the mono button on that one.
Sure no worries. I will post about this tomorrow!
So this was the solution which was actually pretty simple. First connect your moog sub 37 via usb to your computer. Then connect your audio out from your moog to an audio interface. I am using the scarlet 2i4. Make sure to press the SYNC button on your moog within the arpeggiator section. You wont be able to hear an output until you hit record within logic when this function is activated. Within logic look at the following steps below.
1:
2: Go to project settings > Synchronization
3: Go to the midi tab and select destination 1 as Moog Sub 37
Everything should work fine then.
Someone also suggested to turn off the local controls on the Sub 37. Not sure if thats one of the things that helped but thats what I did.
