I had forgot the SUB WHEEL should only be used when you don't use a working aftertouch. The SUBWHEEL work like a substitute for those who don't have aftertouch.
Also the problem with volume pedal is only if one automate the Master volume knob. I forgot one should use the EXP option on the left side.
But still there is issues with the synth lines TOUCH RESPONSE inital and aftertouch levels. (The grey sliders).
According to the value display they are set to boost 60 db at max. That is way too much.
According to the original Yamaha CS-80 user manual, then most voltage controls is 10 volt or less. That i think is 20 db at max. In the original Yamaha CS-80 service manual i see the numbers 6.4 +- .3 volt, and 8.5 volt mentioned. I don't understand this as i'm not a technician. But to me it look like the sliders should boost around 16-20 db at max. (If the values is for a module, then it's half this values (around 8-10 db) per slider.) Is that correct?
Also when setting the CS-80 V3 master volume to the display value 0 db, and when having the VCA levels at 0 db and having this touch response level sliders fully down to not give any boost at allthen the output level seems to be at least 22 db too loud. The output in this situation should be 0 db. (Having the synth lines Sine levels at max give higher output than without using Sines.)
(When the master volume is set to max (21.97 db in the value display), then it's around 45 db over 0 db or around 22 db over the shown value.)
The levels need to be adjusted. I assume Arturia can find out the correct levels.
