In modular synthesis, there's no such thing as too many multiples. Just when you think you have enough multiplexing power, you find a reason to want even more multiples. The Modular Industry has responded to this never-ending need for multiples with an adequate offering of passive, buffered and other, more fancy multiples.
If you have a small studio, or if you’re still learning to trust your ears when listening to a mix, visual aides are really helpful. The frequency analyzer is a budget producer's best friend. The phase scope is also quite useful. But why stop there? Lissajous curves are big fun! Here's a roundup of basic spectrum analyzers and some specialties.
Want to hear proper FM sounds? Try the original compositions by John Chowning. He's the inventor of the technique used in the Yamaha DX7. Here's a nice article about Chowning and the history of FM.
Not your average frequency shifter. This is a one off, custom built, nothing but tubes inside, and it sounds great. You may have heard about Mr. Sala's Mixtur-Trautonium, which is a really nice vintage synth, but his frequency shifter is just as interesting.
The best thing ever. Old Greeks, an unhealthy dose of existentialism, but also Machiavelli, Nietzsche, Marx, Derrida... you name it. The silly voice-over will grow on you. Everybody wants to be smart, write? So now you can fill your head with education that doesn't suck.
When the French one-man company Twisted Electrons shipped it's first batch of SID-based TherapSid synths in the fall of 2014, some users experienced 'stuck notes' and MIDI-trouble but Alex seemed to react swiftly and accurately. And so, by january 2015 the € 399,- for a TherapSid (with 6581 chip, or € 333,- without) seemed a justifiable investment. Long story short: the monster has matured quite a bit.

If you want to use analog synths/oscillators for xenharmonic music, there are MIDI-based options like the H-Pi Tuningbox, or the more advanced Silent Way soft/hardware. And there are modules like the Analogue Systems RS-130. Or you could also try a hack: maybe it's possible to hard sync your hardware with software-generated audio.
