Asymmetrical wave for a tremolo (shoot the moon), any ideas?

[br.a]

Hi everyone, i have a shoot the moon on my protoboard, it sound perfectly, very best of my other EA trem, tremulus lune and pulsar. But i´m looking for some mods: First, a pot or toggle for select asymmetrical wave

I put an extra resistance on wave pot and i managed that the led to come on suddenly and then goes slowly, bingo!, but now need to happen otherwise

knows anyone how to do it?, maybe whit diodes, caps, etc..

Take two 1N4148 diodes and a SPDT on-off-on switch, or a 500K pot.

Lugs:
1
2
3

1: Anode of diode 1
2: Rate pot lugs 1&2.
3: Cathode of diode 2

Connect the other side of the diodes together and run a wire to Rate pot lug 3.

If you use a pot, wire it the same way (with 2 being the wiper).

See the Tremulus Lune schematic for a reference.

I am very grateful. It sounds great
