Roland. Korg. Yamaha. Kurzweil. Ensoniq. Emu. Akai. Remember when the giant names of the musical instrument industry used to make synthesziers? That was awesome. Or, at least it seems in hindsight.
Major advances in synthesis would happen every NAMM show as manufacturers attempted to corner some unique area of the marketplace. Moog defined the performance instrument category with the minimoog, but it was a tough sell. Eventually retailers caught on and more players came to the market, notably ARP and Oberheim.
The next obvious milestone was polyphony. While multiple Oberheim SEMs could be ganged together for polyphony, the Prophet-5 stormed the market with the combination of patches and polyphony. The big names exchanged various salvos in the analog polysynth era until MIDI and the digital polysynth arrived in earnest with the Yamaha DX7.
It was at this time a cottage industry sprang up selling pre made patches for instruments. The D50 arrived in 1987, bringing with it the standard of including digital reverb and other digital effects on board. The Korg M1 quickly followed, ushering in the age of 'workstation' synths with multitimberality and built-in sequencing.
All of these products brought some new key feature or synthesis method to the market. The big names drove synthesis innovation. The market today isn't about synthesis innovation, it is about providing controllers and stage pianos. The people who bought synthesizers were never really interested in synthesis. They played in bands and needed a piano sound, an organ sound, a rhodes sound and whatever generic synth pad patch is required for that one cover song. The synthesizer market was subsidized by keyboard players.
What happened was synthesis innovation migrated to the realm of software where it is far cheaper to develop. This lowered the barrier of entry for the 'synthesizer curious.' No longer was it necessary to spend money on expensive hardware in order to explore. Roland is still under the illusion that they make synthesizers, which explains odd marketing thrusts like promoting synthesizers as a musical 'lifestyle' for bored suburban moms.
There are still people interested in synthesis, but with the proliferation of software and without the earlier keyboard-player-subsidization, the market has reveled itself to be far smaller.
If you look at the history and development of monosynths, you have a variety of manufacturers trying out different sets of features or technologies to distinguish their product. Ultimately, you can't be all things to all people, and if you could cram every conceivable feature into a single synth, it would be incomprehensible.
With a modular, you can take just the features that are important or relevant to you, and come up with an instrument that is entirely unique. Look around at everyone's system. No one has exactly the same thing. Why get an MS-20 when you can basically custom specify your own synth?
I lived though those old days as a synthesizer nerd and spent a lot of time hanging out at music stores spending as much time as possible auditioning the latest gadgets. Like many others, I engaged in elaborate thought experiments (IE: daydreaming) about the ultimate synthesizer. Seamlessly mix analog and digital oscillators. Recreate the voice structure of a Prophet VS. Swap out a vactrol filter with a transistor ladder. Layer four... no, SIX oscillators. Use multiple step sequencers to imply multiple overlapping rhythmic feels. OR, you could make a standard OSC>VCF>VCA bass patch to create a line that repeats over and over and over. The sky is the limit here.
In the 80's, before affordable DAWs and in the new gleam of MIDI, modulars and analog monosynths fell out of favor for obvious reasons: no patch storage, no polyphony, unreliable, tuning issues, etc... all things that matter in the context of performing musicians, but weigh less in the minds of synthesists. No one is purely one or the other, it is our priorities and interests that define the weighting. After a decade of cursor buttons and LCDs, we wanted our knobs back. Cables came a bit later.
Now modulars are booming, but the scale of manufacturing is better suited to a cottage industry. As a result, all the really interesting advances in hardware synthesis are coming from companies that are run out of a garage by one or two people, not the big names.
Now with affordable computers, a lot of those issues that mattered 20 years ago, are less important. Oscillators have better tuning and tracking. Everything is more reliable. Polyphonic patches are actually realistically attainable at some scales, multitracking is affordable and computers provide precision control over any CV input.
I've spoke in the past about
why I use a modular, but I have some updated thoughts that I'll share in a future blog post as I continue work on 'A Funneled Stone'. Consider this a preamble.
