@TQ Real analogue synthesizers are expensive, especially if you want polyphony. I’ve dabbled with the emulated MS-20 and Polysix that comes with my Korg Kronos. There are also iPad and PC/Mac implementations that are more featured than the physical versions they emulate. MS-20 is very basic which is nice because you can build a sound literally from first principles. Polysix is a mite limited and IMO best at making pads and backing tracks.
