Hi.
One praxis example:
I use the AR analog input for my Pocket Operator Rhythm (yes it has “h”-s).
I can change the output level at the PO Rhythm in 16 steps (step 15, 16 is distorted, so I use 14).
PO Rhythm > AR > Overbridge (Stereo Outputs) > Ableton Live
The level in Live is ~ -25 dB for the single kick drum which is very low.
The problem is the PO Rhythm has no line level and the Rytm has no instrument input or Hi-Z input.
Lab example:
I test it with a sinus tone from the Operator (Ableton FM Synth) and send it via audio interface to the AR input.
Level plan:
Audio Interface - stereo line out @ -10 dBV (pro gear level)
AR Input 0 dB FS sinus @ 1.05 kHz (C5) -> Output via Overbridge = -21 dB
to low!
Audio Interface - stereo line out @ +4 dBu (consumer gear level)
AR Input 0 dB FS sinus @ 1.05 kHz (C5) -> Output via Overbridge = -12 dB
to low!
Audio Interface - stereo line out @ high gain (extra +6 dB boost)
AR Input 0 dB FS sinus @ 1.05 kHz (C5) -> Output via Overbridge = -8 dB
well it’s okay!
If you like, use your audio interface as “audio thru” to gain the level, try the high-Z input and the high gain output mode.
You lose a stereo input and output, but you need no extra gear.
