Hi all
I just want to share a setup and configuration to send full 13 or 14bit CV voltage
For a side project (not fully related to audio) I came across a simple way to perform this
I use a AOUT_NG, and hook a summing amp at output
you need to sum 2 out for 13 bit, or 4 out for 14bit
then it’s just need map split at NGC.
like this (for 14bit) each CV take care of a quarter:
MAP11/HWORDI \ 0:0 \ 16383:65535 \ 65535:65535 MAP12/HWORDI \ 0:0 \ 16383:0 \ 32767:65535 \ 65535:65535 MAP13/HWORDI \ 0:0 \ 32767:0 \ 49151:65535 \ 65535:65535 MAP14/HWORDI \ 0:0 \ 49151:0 \ 65535:65535 EVENT\_CV hw\_id=1 id=1 type=PitchBend chn=1 range=map11 value=0 ports=10000000000000000000 EVENT\_CV hw\_id=2 id=2 type=PitchBend chn=1 range=map12 value=0 ports=10000000000000000000 EVENT\_CV hw\_id=3 id=3 type=PitchBend chn=1 range=map13 value=0 ports=10000000000000000000 EVENT\_CV hw\_id=4 id=4 type=PitchBend chn=1 range=map14 value=0 ports=10000000000000000000
Side note:
-increasing definition will give you less output as you see
-you need a good layout and proper grounding/0v reference, for a 0-5V CV (my use case) the step is 300uV !!!
