HSO Multitimbral?

I’ve just downloaded HSO running on a Mac.
Was previously using the Boxed DVD version on PC.

Is the new version one instrument per instance?
I can see the advantages of that but the Instrument Rack gets really full.

Alternatively you can load it from HSSE, 16 channels multitimbral…

HSSE? Halion Sonic?
Will check that out.

I’ve got Halion 5 coming in the mail
