does anyone know where the patches are for Eyeliner Bass, Space Pluck, and Mono Bass?

It is relatively simple to program synths (relatively, because it usually depends on the number of parameters to play with). But more often there are only few basic steps to make:
1) Set the sound source (waveform generator or OSC) and define its pitch (there could be various waveforms that you can combine and/or add or subtract to/from each other)
2) Set filter (low pass, high pass, notch, comb, etc. - available filter types depend on the instrument)
3) Set the ADSR for your sound source and filter (that's how your sound behaves, when you press, hold and release the key)
4) Fine tune the parameters above until you get "that sound"
