I'm using my PX S-3000 for mostly solo piano and duo gigs with acoustic guitar. It's just what I needed for those.
I will I'll be using it for some jobs with my blues band and occasionally a cover band.
I have 4 banks set up for this.
Bank 1. 4 different acoustic pianos
Bank 2. 3 Rhodes 1. Wurly (60's ep)
Bank 3. 4 Clavs
Bank 4. 4 Pianos with Layers (string, pad, ep, synth)
Anything more and it will become hard to keep straight without the ability to name and organize registrations.
Luckily I have a Nord Stage 3 Compact and will use that to do the heavy lifting
(organs, synth, Wurly, horns, etc) as an upper keyboard.
This is is an amazing keyboard and a great value but it's not going to be a top candidate for a Stage Piano for people who need many sounds and set-ups to get through their gigs.
If someone ever designs an app we can connect to and use it to Name, Save, Organize and Recall Registrations there would be many grateful owners and even more customers.
