Hello,
I would like to please know how I would go about connecting an external audio signal into the SUB-37.
I tried what your manual said, and it did not work the way it said it would - I think whoever wrote the
manual skipped a few important steps that a novice would be unsure of.
Evidently I am not the only one asking this question because there is the exact same question being asked about the SUB-Phatty, where a guy on YouTube goes through the following explanation:
Plug the audio Out of the SUB-Phatty into an amplifier and make sure that you hear sound as you play the SUB-Phatty.
Plug a working source audio signal into the ext audio in port of the SUB-Phatty - make sure that the source device is outputting a signal.
Plug a dummy 1/4" jack into the KB Gate input of the SUB-Phatty - this dummy jack cord is not connected anywhere on the other end.
Turn both oscillators right down.
Turn the Noise knob right down.
Go into Shift mode by holding down the bank 4 preset button.
Turn noise knob up slowly till level is right
Go out of Shift mode by holding down the bank 4 preset button.
Can you please confirm if this is the correct procedure for the SUB-37 as well ?
If it is not - can you please tell me how to input an external audio signal ?
I want to be able to run a guitar signal, or another keyboard signal through the SUB-37.
All I found in the Sub 37 manual is a description of the ExtIn/Fdbk level control. No directions.
I think those instructions for the Sub-Phatty have nothing to do with the Sub 37.
Simply plugging in a line-level input to the Audio In jack on the side of the Sub 37, turning up the level control and turning on the push-button in the mixer section (the same as all the other mixer inputs) should let you hear the external signal when you play a note.
As for a guitar signal - I think you will probably need a pre-amp to boost the low-level guitar signal to a line level signal for the Sub 37. Maybe not; maybe the Sub 37 input circuitry has enough gain to help you there.
If you want to hear the external signal without playing a note, then you have some more work to do. Maybe use a foot-pedal to trigger the Sub 37 from the KB Gate jack input. Or ‘Latch’ the Amp Envelope and use a high Sustain value to let the signal through. The Sub 37 manual should help you with those.
I’ll see if I can play around with it tomorrow after scrounging up a 1/4" plug. I suspect you’ll get it working before then!
Thank you sir for the push in the right direction - I got it working and it sounds so cool. I basically fed a polyphonic signal from my digital synth into the external audio in port of the Sub-37, and was able to get it all working once I plugged a dummy 1/4" jack into the KB Gate port, and turned down the oscillator levels.
This shouldn’t have been so complicated - once you told me to turn on the ext in button in the mixer stage, and I gated the KB that was it. Very logical with your help.
Anyways, thanks again, I’ll try running my guitar through it - but I’ll take your advice & feed it through my signal processor first to get some gain.
I’ll post the results later.
Hopefully once I learn how to get some good sounds out of that thing we can trade notes again.
Take care,
