Hi
You may already be familiar with a PC3 program 89 Slo QuadraPad.
I edited and customized this program. It sounds very beautiful. When you press it gently, it sounds very nice and soft and higher tones have a really nice swell, but when you press it hard, it sounds more like a string session. I use it many times on live performance.
Algorithm: 2 POLE LOWPASS - XFADE - LOWPASS

Slider A - Lowpass filter frequention
Slider C - 2 Pole lowpass resonance
Slider D - 2 Pole lowpass frequention
Slider G - Chorus
Slider H - Drive
Slider I - Delay, Reverb

I hope you will enjoy it
Have a nice day!
