We often receive emails from people who want to know which is best, software synthesisers (plug-ins) or hardware sound modules and keyboards. We're sitting on the fence for this one but here's s few thoughts to help you decide ...
Great to program if you have a knob for each parameter
Real-time performance editing
Sounds better (yes they do!)
Don't crash (often)
No latency (yeah!)
Takes up space
Harder to transport
Some are hard to keep in tune
Backing up patches is a pain
No repair costs!
Software often offers features hardware can't
Easier to create and backup patch libraries
Patches saved with projects
Stays in tune
Setup and patches are saved with a project/song
Don't take up much space!
Emulations don't sound like the real thing(?)
Using the same CPU / DAW and DACs for all your plug-ins makes everything sound ... well ... kinda 2-dimensional
Programming with a mouse sucks
You better have some CPU horsepower!
