I'm busy making up the playlist for the new format - Public Domain (in Canada) classical and opera.
The biggest problem has been that the way I do voice tracking in Zara for oldies (short in duration) just won't work effectively with potentially long classical pieces (and even longer opera).
So here's what I'm doing. Each movement in a piece is placed in a Zara .seq file. I'm recording 3 lead-in voice tracks, and 3 lead-out voice tracks (short, medium and longer in length, with corresponding more information) for each piece. The lead-ins go into a random track directory at the start of the .seq file, and the lead-outs at the end. That way, there will be a total of nine different lead-in/lead-out combinations, making the station sound a bit more 'live'.
I'm using my new Shure S-2020 microphone, along with a mixer for amplification, to record the tracks. The microphone sounds really nice, and more natural than the USB one that I've used in the past.
This is going to take some time, but I believe the results will be worth it.
I'm still on the B's (there are a lot of classical composers that start with that letter).
I hope the format you are compiling is also what you like yourself and not just something to not have to pay royalties for. It's much better when you "like" your own station!
All my voice tracking are done via high quality setting on a voice recorder in 192 bit rate MP3s and the jingles/promos I got from here.... https://imagingthing.com/ also in MP3s, and you can make some for your format and then make many multiples of 7 or 8 of them inserted in the mix.
Then I just transfer all these with the music playlist on to Zara. Trying to get a certain thing to happen at a certain time ongoing like time announcements I have not yet figured out, even with help it didn't work.
