Can the Subharmonicon output unquantized pitch values from the patchbay?

Yes. By default, the SEQ 1 and SEQ 2 output jacks will output a control voltage that reflects the current Quantize settings. This behavior can be disengaged by pressing and holding the QUANTIZE button until the LED flashes, at which point the Oscillators will continue to respect the current Quantize settings, while the SEQ 1 and SEQ 2 output jacks will remain unquantized at the patchbay.
