I'm trying to program Imagination's 'Music & Lights' synth bass patch. This bass sound is not the same as the 'Just an Illusion' patch. The latter is smoother with less grit/bite than the sound I'm going for.
I'm no expert (hence this post), but I think the Music & Lights patch comprises 3 waveforms: A saw/square mix (square mixed at around 50% of the saw) for the grit/bite and a sine (or possible triangle) for the sub.
I programmed the MIDI parts and then began trying to create the patch using the Arturia Minimoog. I originally focussed on creating the grit/bite part of the sound as I figured I could easily add the sine later. I couldn't get anywhere near it. So, I tried the Imposcar next. Again, no luck.

So, I turned to my trusty Juno (the only analogue hardware I own) and tried again. This time I achieved a better result and was able to achieve a reasonable 80's style funky synth bass. The patch I came up with on the Juno had a lot more grit/bite than my previous attempts using softsynths (because of a real analogue filter perhaps?), but it still wasn't similar enough to the Imagination patch.
Is this a case of 'a bad workman blames his tools' or are my tools inadequate for the task I'm trying to achieve? Should I just forget it and save up for a hardware Moog or should I try some other VSTi's?
I'm a great believer at getting things right at the source, but after experimenting with this for several days I'm not sure if any of the sources at my disposal can do the job. Should I persevere with compression/distortion/amp/speaker simulators to get the bite I'm looking for? Or am I just banging my head against a brick wall because:
1. The sound I want is specific to a certain hardware synth.
2. Softsynth filter models pale in comparison to the real thing.
....sorry for the rambling/long post. I could really use some expert advice on this!
