For the percussion patch, I used the FM option of the retro synthesizer and applied a low pass filter at 24 dB. I slid the cut off for the filter to the right a bit, decreased released in the amp env and filter env options.
For the nice sound I used a low pass filter at 24db. Reduced vibrato to 0 and used the chorus function of the synthesizer. I increased release for both filter env and amp env.
For the alien sound, I used the FM option of the synthesizer with a low pass filter at 24db. I decreased harmonic and increased vibrato. I increased attack slightly on both filter env and amp env.
