I have a Blofeld and an iPad with tons of synth/drum/fx/sampler/etc… apps. I recently spent a full day with each sitting outside on my deck with the Octatrack & Digitakt on separate weekend days. Good music came from both sessions but I ended up just playing random sounds from the iPad and mangling them in the Octatrack and Digitakt. With the blofeld I actually sequenced stuff as well as randomly sampled stuff. The more I play with the Blofeld the better I realize it is. If I had to pick only one it would be the Blofeld.
One thing that helps is that I printed and laminated a reference sheet to the Blofelds MIDI CC#'s so I can quickly assign anything to be plocked on the blofeld. Another cool thing you can do with the Blofeld is make use of the x,y,z controllers in the modmatrix. An example is assigning both filter cutoffs to x, y, or z in the mod matrix. Offset each of them and adding some resonance to give you some almost “formant” sounding filters. Then plock the x,y,z controllers to move both filters at once (kind of like the Virus).
I have the SL license too and started to create some oscillators based on a bunch multisamples I recorded from an old Roland XP-80 with a vintage synth collection card in it (before I sold it). First tests with the sampled oscillators is they sound more beefy (though built in stuff sounds good too).
Also the FX aren’t as bad as everyone makes them out to be. Once issue is that they can’t be changed in realtime without clicking or breaking up. The other is that they have sweet spot about the size of a pin head at various locations, but they CAN sound good.
I honestly almost sold the blofeld because I had it for a long time and never really gelled with it. Recently though I’ve started to really really like it and I’m not sure what my problem was before but it’s really an amazing synth at the price it goes for. Modulate stuff and use the wavetables, I think that’s the trick to getting great sounds from it.
So conclusion: get an iPad
