Got my Synth 9 today Tracking: Some of the synths track to Low E perfectly ... all the synths track pretty consistently to low A as advertised. The the 2 main settings knobs def effect tracking, some synths much more than others. I have a EHX Pitchfork (upper octave) in front of the Synth 9 & a dirt pedal & revert/delay after. You can get some very convincing keys sounds going. I'll try to shoot some video in the morning.
