Im not offenced, 
I’d recommend you spend some time with a modular synth and see how your current method flies
Keep in mind that when you say ‘tweaking is like making your own’, you’re not just bumping your skills up a level, you’re also depreciating the value of the efforts of people who really do make their stuff from scratch.
Dont you agree that each synth/app has its own degree of difficulty?
Creating one MBFM patch is not the same as coming up with a stochastic note generator, cellular automaton modular patch.
And yes, i had the most fun just sending CCs to the default GM bank, because sometimes you need to just let it go.
I design and program audio apps (and, what a coincidence a modular app) for a living.
For me MIDIBox is a hobby (im a total electronics newbie and like to learn the “other side” of the trade),
and idd like to try the presets the others did, like i like trying out presets of my collegue’s VSTis,
when i just want to play music and let the right brain sleep.
Its not because i couldnt be able to do “some” of them myself. Its because i want to appreciate the work people have done.
The goal is in no way “claim you made them” (although again, lets agree on the difficulty level here), or diss the
hard work some have done. Its the same thing with DJs vs Song Writers. for me the real star here, is TK for his code.
That requires effort.
Yeah my post disapeared, because my i tought i had a better ansewer
original post for the curious;
But sometimes i just feel like i have a left brain left that just wants to noodle with presets!
(especially after a few drinks, i cant even understand my own apps 
I dont mean that you can do a cellular automaton, a stochastic note generators placing random modules in a patchbay. But the parameter list of MBFM is so small, heck even with a random script you can generate pretty damn cool stuff, and with FM, by experience, its either youre a fraud (and say you analysed the maths behind all the harmonics required for a sound, then you placed the exact params, or you admit that you just random NOODLED with the thing :)
Im not an FM expert by any means, but our modular app has a 2 op example FM patch bundled.
Yes there are some that take the time to do proper FM presets (ENO) (and think about what they do), and thats why i asked in the first place. For me the MIDIBox stuff is a hobby. (even if i built and coded a MIDIBox to drive a SN76489 chip - that i hope to release soon after my zillions of other things). Somtimes i just feel like playing and not thinking (that also includes being a whiny bitch using a pseudoname) …
Doenst that occur to anyone else?
