I'm developing microtonal algorithmic music, leaning towards chiptune sound, and for sounds/timbres/instruments I found the Plogue synthesisers to be the best - https://www.plogue.com/index.html - they have 3 great FM-synthesizers/emulators of Yamaha chips: OPL2, OPN from megadrive, and DX7. Bought 2 of them on this black friday.
