I used modified presets of Retrologue that comes with Cubase 9 and also some of Yamaha emulators that came with the keyboard I use but which are not free otherwise and also a Juno emulator, but I meant I used only the stock plugins of Cubase for EQing, compression, reverb and so on, in case it was useful for anyone giving me advice on improving the mix.
I totally agree about the drums, I don’t seem to be able to mix them properly, I’d like to just use the ready to go drums that come with Groove Agent but I don’t like the patterns nor the samples that come with it
