I've been playing for like an hour with the demo of MSF and sweet mother of Jesus... yeah it's good.
I haven't even scratched the surface... more like looked at it... from a distance
but here are my quick initial impressions.
The UI is ugly but honestly it's not as bad as I assumed it would be. The weirdest thing is actually how some panels are stretched over a huge space.
Regarding the general workflow... it's... fine? There's practically no learning curve for the bread and butter stuff. In like 10 mins I was adding oscillators, filters, effects, modulations, etc. The navigation between modules is very quick. Click on the grid, open a module, edit. Reminds me a lot of Zebra.
Of course it has its own idiosyncrasies and I've had a couple of head scratching moments, but the general structure makes perfect sense. A lot more sense than say Falcon which is structured like a Russian Matryoshka doll of nested layers and doesn't seem to want to help you navigate that structure. MSF is direct and straight forward.
MSF has a lot of little things that are fantastic in terms of workflow. For example, all generator modules have a mix knob for example. When I saw that I said "exactly!" out loud. All synths should have that.
Many of the advanced modules will certainly take time to master, but thanks to the presets with custom UIs (like MTurboDelay) I really don't see myself digging deeper than that for quite some time. I mean, does anyone really need more than 40 freaking delay plugins?
And the sound... I love it but don't expect the U-He mojo here. It does have some "analog" options for pitch drifting and such but, so far, I wouldn't say it has a naturally analog juicy sound. It's probably the filters although maybe I just need to dig deeper into this thing.
I could go on for hours... but yeah this is really a "desert island synth". It's not a synth though... it's more like everything everywhere all at once.
Yeah I'm a convert. I've seen the light.
And I still haven't even loaded a sample
