i made this patch when experimenting with the boundaries of myA6.
it seemed that there were big diffenerences between the different filter/vca chips. how exactly it works i'm not sure of, however changing some of the chips solved the "problem".(adjusting the filterfeedback per voice also reduced the differences)
*just play the patch and eventually monitor the different voices by :global/voxmon.*

today is saterday ,so no new patch (by the way where are yours patches, just drop one and let us enjoy them too )
instead of a patch some, previously made, grafic picture of the different envelope slopes of the a6 ( nice for above the bed or anyother wall)
as comparison i also incuded a grafic of the roland analog system100m. as you can see lin. or exp. are best suited for attack and log1 or log2 for decay and release when reproducing the system100 envelopes. these are what i use mostly for my analog patches b.e. the crumar ds2 / analogsynth default patch on this site.

i forgot to mention that infact the envelops of the A6 can be too fast !
for a normal analog synth a minimumvalue of 6-8ms mostly suits better.

(this patch is also usefull when wanting to test your oscillators)
the autotune of the A6 works reasonable, just that
even after repeated autotune differences of up to +/- 4cents can be found (measured at A440, with peterson vs1 strobetuner)
to make tuning more noticable i use the following defaultpatch.
1 after warming up ,ca15minutes, press autotune ,switch voxmonitor on and press A4 repeatetly.
2 when voices sound oke, switch them of temporary.
3 then renew tuning for the remaining patches by pressing "oscfreq tune"
4 repeat stage 2 and 3
5 after all voices have been properly tuned, turn them all on again , and voila, a tuned A6!

for those not used to tuning oscilators or those simpy wanting to hear the differences between the oscilators i made the following little tunegame.
switch voxmonitor on (under globals)
put ribbon on hold
play a key and adjust the tuning of oscilator two by moving along the ribboncontroler.

don't like the a6 default patch so modified it a bit.
differences are b.e. :controlrouting of modwheel to lfo2mod's (they are more flexible then the lfo 1), waveform , filtersettings, env's and div other settings are adjusted to quicker start from a reasonable sound when tweaking. ( at least that's my opinion, always open for suggestions)
one last remark: in general , when switching external audio-in: turn levelnoise/ext to 5 or less afterwards to avoid distortion, i couldn't implement this so hereby as tip.
