Controlling the LFO on external devices (Volcas)

OP-Z
#1

i’m trying to control the LFO on volcas with the OPZ via MIDI - the Volcas allow this, but the app doesn’t allow you to control the outgoing cc’s aside from some general ones, just the incoming ones.

The manual says you can control this on the midi.json file, but when I open that up, I have no idea how to interpret what I’m seeing.

can anyone parse this for me?

"parameter_cc_out" :

16 rows must mean 16 channels, but for example if I want to control the LFO speed for channel 5, which entry am i modifying according to this table to match the CC of the volca? Is it the 10th entry in the 5th row? OP-Z guide: midi

#2

unless i am mistaken
each row corresponds to each track on the Z 1-16
each entry in the row corresponds to every parameter for that track
each track has 4 pages of 4 parameters each controlled by the encoders
for a total of 16 parameters

so page 1 of the 4 encoders is the first 4 entries
page 2 is 5-8 and so on.

the entries in the table correspond to what CC each page/encoder sends out.

thanks! so the LFO rate is the 2nd parameter on the 3rd page, so that would make it number 13? and if the CC for LFO rate on volca is 41 then i change the 13 to 41 on the relevant track row?
