Besides, just about any DAW on today's market have a sufficient set of FX plugins and many have a "synth" as well as some maybe have a piano. ?
At least CbB has most of these (TTS-1 covers a lot of ground even if it has dated sounds).
Initially you get a set of essential plugins free. After that there are additional plugins avail for purchase. Their prices are not for the faint of heart though. Wait for sales, I say, and even then some can still be costly; but d.a.m.n.e.d fine plugins though.
