Worth it for the SRX-07 alone. The strings and brass on SRX-06 still show up in major label records for a reason.
Buy individual SRX plugins on sale (they go to ~$30-40 each) if you only need one or two boards. Subscribe only if you want the full Roland Cloud ecosystem (including Zenology, Jupiter-8, etc.). Avoid if you need deep sampling or modern UI. roland srx vst
