Maybe, before reassigning a category to a certain piece of gear we should provide also new categories.
For instance, keyboards and synthesizers lack "expanders" category, i.e. keyboards without a keyboard.
A subcategory could be also "Expansions board" that are installed into synthesizers and expanders.
For this reason, SR-JV80-02, 04, 10 and 11 can't be in Software Plugins and VSTS category
On the other hand, all the other soundboards that are in "keyboards and synthesizers" category should be moved to a new subcategory called "Expansions board".
Yamaha BC-3 at present is in "keyboards and synthesizers" category, but is a keyboard accessory.
Studio Equipment category is not for Emu Proteus2000 - MIDI and audio Interfaces are correct for this category.
AudioTechnica PRO8HEcW is a microphone but was enclosed into Studio Equipment category.
Effects Pedals: Yamaha FC3 and FC-7 made me laugh. Alesis Midiverb 4 is not an effect pedal.
Other Gear:
JBL-LSR10, LSR305, Yamaha MSP-7 Studio and MSP-5 Studio are studio subwoofer and monitors respectively
Roland JD-990, Roland M-GS64, Yamaha MU90R and Korg M1REX are expanders
Roland SR-JV80-07 is an Expansion Board for synth and expanders
Roland SR-JV80-09 is an Expansion Board for synth and expanders
SM-Pro Audio Q-Amp is a heaphone amplifier
Hollywood Strings is a virtual instrument...
That's all for now...
Why I inserted multiple new instruments and my IQ remains always the same?
