For me, I don't like the idea of Eurorack modules that require a case with power rails sitting alongside self-contained products that are plug and play. New/beginner users could get the wrong idea and affiliate-link their way to buying a $100 module, not realizing the substantial investment needed to get sound out of the thing. I suspect that this is why Sweetwater keeps unhoused/non-powered modules separate from everything else, despite their otherwise broad and sometimes-wonky categories for synthesizers.
If you look at the category-breakdowns Equipboard has for guitar pedals, all things synth are being grossly underserved here.
I know Equipboard's thinking on categories comes from the categories Sweetwater & GC still use, but I doubt anyone here feels users are being well-served by having "Tabletop Synthesizers" stuck in DJ Gear.
And what's an Audio Sequencer ?
Given that semi-modular synths exist in both keyed and desktop/non-keyed formats, maybe the answer is to have an option to filter all the relevant synth categories by things like "semi-modular", "eurorack voltage compatible", and "eurorack-mountable"?
Update:
Biggest issues with current categories, synth-wise:
The "Synthesizers" sub-category needs to be narrowed down to "Keyboard Synthesizers". This would make it clear that desktop/tabletop synths go elsewhere.
The "Tabletop Synthesizers" category needs to be moved from "DJ Gear" to "Synthesizers, Keyboards & MIDI" to sit alongside the "Keyboard Synthesizers" sub-category. Also, we need to rename it "Desktop Synthesizers" as this is the more current industry-wide term.
The "Sound Modules" category needs to be renamed to "Rackmount Modules", "Rackmount Synthesizers", "19" Rackmount Synthesizers" or similar so it is clear this is for the now-extinct 19" rack mount and half-rack formats. There is no longer a need to distinguish between what the industry used to call "sound modules" and "true synthesizers", because the days of rack-mount ROMplers full of piano sounds are well behind us, and nobody will be offended or confused to see a few of these old ROMplers sitting next to other rack mount gear more in line with a true synthesizer. People cared back when true synths were almost extinct, but now that the tables are turned, it's a non-issue, I suspect.
"Modular Synthesizers" needs to be expanded to encompass at least 3 sub categories: Semi-Modular Synthesizers, Synthesizer Modules (un-powered, un-housed), and Modular Cases & Accessories. The Semi-modular category would ideally be 2 categories: one for keyed and one for desktop, but IDK what the best compromise is here.
"Audio Sequencers" needs to be renamed to "MIDI & CV Sequencers" and moved from "DJ Gear" to "Synthesizers, Keyboards & MIDI > MIDI". Anything that is primarily aimed at sequencing external gear, rather than producing its own sounds, would go here: old dedicated midi sequencers from the 80s and 90s, CV sequencers for Modular, hybrid MIDI/CV sequencers, etc.
Audio Samplers needs to be reworked to clarify that it's for old 19" rackmount samplers and sampling keyboards, but NOT for MPC and Elektron-style self-contained "Production & Groove" products. I also think this category would be better served over with Synthesizers, Keyboards & Midi than DJ gear. Separate categories for keyboard and rackmount samplers would be great.
It's weird that drum machines are over with the DJ Gear... isn't it? That product category was never specifically aimed at DJs until the likes of the Pioneer Toriaz, which, ironically, would probably go under Production and Groove, which is not in with the DJ Gear.
Electromechanical keyboards like the Rhodes, Clavinet, OG Mellotron need their own category. This is an extinct product segment, but they don't belong in any of the existing categories, unless we want to expand Organs to include 1970s electric pianos and the like, which seems odd.
A new category for knob-based controllers and control surfaces needs to be created. The DAW Controllers category is overrun with these non-DAW-specific controllers, most of which are MIDI-based, but some are high-end HUI control surfaces and other such automated-fader and big-knob goodness aimed at ProTools types, but not specifically tied to any one DAW... or just rename it "Control Surfaces" and let it be the catch-all that it is, with no specific attachment to DAWs.
I know these sound like demands I'm shouting out, but I'm sure there are solid business/technical reasons why a lot of this isn't in-place already.
Ideally, we'd have a system where a piece of gear could exist in multiple categories. So an Elektron Octatrack, for example, could be in with the Samplers AND in with the Groove Boxes, and maybe even in with the Desktop Synthesizers, Drum Machines, etc... but if we are locked into just one category per item, I think some of the changes above would make it easier for users to pick the "right" category when adding or editing gear, which would make the gear ranking system here more meaningful and useful.
