Green-----square
Orange----triangle
Blue------ sine

Give it a shake to get it going. It will need a few second to stabilize. With the new scope you can see the distortions in all of the wave forms.  The power supply at the bottom is only there to provide a timing signal for the scope.

Very, very nice! I wish I had a better understanding of op amps! This is great. Bravo!

only sine is trashed rest waves is clear like tears so it isn't so bad as u describe. maybe using a diode converter will be more suitable to convert triangle to sine ? second low order integrator are good when convert square to triangle but it's rather all what it can do good. and integrator that is not taken into positive feedback that drive whole oscillator will start to attenuate output wave as u increase frequency just a little. so it's good to use it as timing device for square generating opamp instead of capacitor alone. there it will not be attenuated .

Good ! ..but most possible settings are... ( 16K =27K) ; (40K , 50k * 3 = 100K ) ; (400ohm =10K) ; (6.36K = 15K ) ; (600nf = 22nf ) ; sine-wave out feedback (20nf = 10nf ) ; then ,,red-point connect to 27K.
