I created a morphing base using a modified digital saw (OSC1) and a sin (OSC2) oscillator, where OSC 1 is cycling through its wave table. I used a 3 voice unison in both oscillators with a 0.02 and a 0.05 detune setting. All oscillators and Sub have been transposed down by 2 octaves. I added a noise at reduced volume what can be heard towards the end of the long notes, as the band filter reaches the higher frequencies.

I linked the reverb FX mix level to ENV2 so that the delay only starts after holding down the note for a while. This way short consecutive base notes can be played, with the reverb effect only affecting the long notes.
