Hello, I am with an upstart band. We need a keyboard synth. What is a good one to start with?

Are you looking for synth from the Itallian brand name General Music?
The company General Music makes a synth called Equinox. I do not know if they are getting a newer model sometimes this year. You can also go to the general discussion room and ask this question about other models from Roland, Yamaha, ...etc

Maybe this room should be called GEM?

What kind of music? What sounds are you looking for? Have you ever owned a keyboard, are you a gear head? With these answers, I can point you in a direction, either with Generalmusic keyboards, or to another brand.
