I have noticed that almost every time i use the oscillator octave switch quickly the oscillator wave gets distorted and the annoying distortion doesn’t go away unless i switch to a new preset! has anyone else experienced anything similar? this is my second sub 37 i ordered from guitar center. the first one had the exact same issue so i assume someone else must have experienced the same thing or I’m just doing something completely wrong… I’d love to hear your thoughts.
Yup, same here!
not seeing or hearing anything but the octave changing, when I change octaves quickly and repeatedly.
I am using firmware v1.0.4, which is scheduled for official release on Monday.

You could try this version and see if you have the same symptom. If so, maybe you could post an audio recording showing before/after this distortion, so I can analyze it.
Is local control on or off when this happens? Is any MIDI connected to the unit?
thanks,

Hey guys thanks for the replies. So I believe I figured out the issue. This only happens when im using USB to send midi (from Ableton) to my Sub 37. I switched to a good old midi cable and so far its been good. So far my conclusion is that this issue only happens when you are sending midi through USB from a DAW (Ableton).
Thanks Amos i will install the new firmware and will test the USB again and record some audio for you but in short it sounded like the Octave switch would stick to a lower Octave, get distorted and would never release unless you switch to a preset.
On a more general note do you recommend a balanced 1/4 or unbalanced 1/4 audio cable with the Sub or does it even matter? I hear some static noise currently connecting to my audio interface using unbalanced cable.
Thank you for your help.
OK, if it only happened while MIDI to/from Ableton then I think I can say with confidence that this is fixed in firmware v1.0.4. There was a possible MIDI loop that could happen before… test and see, but I expect it’s fine now.
Regarding the static noise you are hearing, does this also go away when you disconnect USB?
USB is notorious for causing “ground loop” type noise in computer audio setups… I had to fight this in my own studio. There are multiple ways to address the problem. One simple way is to tape over the ground connection on the USB plug. This doesn’t cause any new problems since the unit is still grounded via the power and via the audio.
here is a related thread with more info on USB noise-taming:

Interesting since the Midi cable worked fine last night. I’m guessing the Midi loop issue you are mentioning only impacted USB? is it possible?
I believe I could hear the static noise even with a regular Midi cable and an unbalanced cable out but I will check as soon as i get home and will let you know.
Thank you for your help.
