A-117 modification

2012-02-01 by istari

hi

i just tested around the A-117 oscillator part. i played with the 
trim-pots and now
thinking about adding some external pots instead of them to pitch 
adjust them from frontside.

i simply added also some lfo voltage to the middle pin and found some 
little response to that.

did anymody did that before? i also thinking if something else then 
the 250k pot will sweep
the oscillators more deeper.

wonder if the CD40106BE is doing the osc sounds or if it belongs to 
the digital noise. as far
as i think both unites are kind of seperate on one pcb.

the oscillators do some nice drony sounds beside of their main aim 
for cymal percussions.
