in lines and waves there are 16 parameters controlling ADC->DAC routing.
adcN_dacN with N in [0, 3] = 16 patch points.
(well, in waves they are patch points and in lines they are slewed multipliers.)
in lines there’s also adcN_delM and delM_dacN, with M in [0, 1], so 16 more.
if you set adc0_dac0 and then physically connect dac0 to adc1, then adc1 will be adc0 delayed by one sample at 48k. (which is the only SR the aleph will feasibly run at without hardware hacking.)
adc0, adc1 and dac0, dac1 have analog boost/cut knobs. (the dacs share one knob.)
adc2, adc3, dac2, dac3 have no analog volume controls! they are just there for weird routing/mixing ideas.
and that’s about all there is to know about the routing i think!
so in a word: yes (it is)
and in short: yes, if you mean what i think. the paths del1_del1 and del1_dacN have identical sources.
