Padshop Pro is great, but I can’t say that it’s very versatile for general song writing. If it is, standard sounds require too much effort, the entire thing is very fiddly, and sort of ‘take what it gives you’. Does it sound good. Yes it does.
I used to love Gladiator, but it has a particular sound, ans sort of stereo quality that sounds really dated, but can be useful at times. It does not sound amazing these days, but there is a time and place for that sound.
Right now I love the TAL Juno emulation, it covers a lot of territory, sounds clean (and modern, to be ironic lol).
I am a big PPG fan, I think it’s also pretty flexible, even when it’s not supposed to be.
I still really like the Cubase synths, Prologue, Mystic, Spector, but I HATE HATE HATE the modulation and envelope page. Way to make something a stupid and un-intuitive as possible. I think Retrologue was ok, until I compared it. I do not like it anymore, but it is useable. It has some good presets that can be utilised.
oh yeah. The Arturia Collection. Most likely to find a plethora of sawtooth strings to use, oddly enough the Jupiter did not have the best synth brass, which suprised me. It’s a very useful collection to have… some of the modulars, I still need to figure out.
