to avoid any confusion:
use/load the default -Init- patch
1) set Osc1 to Sine and set Osc Balance to Osc1 (if you whant to hear both then set Osc1 + Osc2 to Sine,
set Osc Balance to 0 and set sync 1+2 and Osc2 Detune 0)
2) set Phase init to 1 (Common Parameters)
3) set Punch Intensity to 0
4) set the "Key Mode" to Mono 1 (Common Parameters)
there you have it
