Honestly, don’t get caught up in the some of the comments about the stock synths. They’re not inferior, they’re just different.
If you read some of those posts, you find people trying to recreate something in another synths and comparing it to that, but just like hardware things are different.
In live you are working with core oscillators. You do need to choose which effects to run through (or use presets to start from). If you don’t like the setup, you could also just do this once and save as your synth to work from moving forward.
Now there should be absolutely no complaints about filters in Live/Push 3. Andy Cytomic collaborated to add algorithms from, or based on the Drop. These additions (from 2015?) will make anything large as needed… just look for Drive options on selected algorithms.
Cytomic’s the Glue is also there.
With a soft synth the built in effects are often sub-par compared to 3rd party plugins, but they become part of the overall sound especially when pushed by sound designers who look for sweet spots… again no different than in the hardware domain.
Live’s tools have sweet spots and M4L offers even more tools (think routing, sequencing, modulation and use of IRs) to build even more options than any soft synth.
Again, think different and let go of what you’ve used before. If you haven’t spent time designing your own sounds (not assuming/I just don’t know) then it’ll seem a little convoluted at first, especially if you don’t know where to look.
If you’re building out in Live to export to Push 3 (strongly suggested as not all parameters are available yet) then remember to right click on the device bar for more options and look for additional menus.
