I am into playing around with hardware synths. Right now, I only have a Korg DSN-12 (for the 3DS), a Korg M01D (also for the 3DS), and some VSTs. I originally thought of getting a Korg Minilogue or a Waldorf Blofeld for my first hardware synth, but I found out that FM synths such as the DX 7 and TX81Z are cheaper than these. However, I heard that many of these FM Synths are hard to program. The only FM synths I know that are easy to program are the Korg DS-8, Yamaha Reface DX, and the Korg Volca FM. The problem with these is that the DS-8 is not that unique (maybe limited) and lacks a sequencer, the Reface DX is 4-op with 4 voices and lacks a sequencer, and the Korg Vocla FM has 3-voices (fortunately has 6 op). Any suggestions?
