as far as inividual velocity on certain keys, the contacts at the back
end of the key in question should be peaked at under the little white
cover to see if the contacts touch in the same order as the working
keys....part 2 my bad on the ep if it is channel 1...directly under it
in channel 2 is bass possibly????does it work properly....Why I ask is
on the front side of the m cards is the tuning and scaling for each
footage(on the top half) on the lower half is where level adjustments
could be tweaked for individual waveforms and noise can occur in
different waveforms if "any" pot is tweaked passed its intended
location....the lower two have to do with envelope and the knobs on the
back edge are filter cutofff, resonance level and filter envelope
timings........now with the presets he has mentioned dont work ... have
a 0 sustain level in the envelope making me think on that one card the
decays are set to quick resulting in the need for the velocity amp to
kick in so you can hear it .....thats why I asked if clav2 and gt 2 were
the only ones like this as harps2 and bass?? also have 0 sustain in the
envelope.....in arturia land these are the bottom row presets that are
yellow to the right of the red"brass"and to the right of
white"organ"......
