What’s going on ?
Lots of guitar stuff. Pedals.
Some attendees in the electronic synthesis world :
ASM / Medeli have booths next to each other. ASM has more or less announced they have no brand new synth to announce at NAMM.
Embodme is there, presumably to show their ERAE II.
Melbourne Instruments is there and there is indication they may have a new controller. ( thread )
inMusic has a booth, that includes eight of their brands, Moog and AKAI being a part of that. It seems likely there will be new things.
Music Tribe has a massive booth that includes their many brands. Expect new announcements and recent announcements to be on prominent display there from Behringer.
Stylophone has a booth.
Expressive E has a booth right next to ASM/ Medeli.
Groove Synthesis is there.
Korg is there with their brands, including all their guitar stuff.
Roland.
Yamaha the everything music company.
The MIDI Association is there with their MIDI Innovation Award booth. Hopefully some MIDI 2.0 stuff is awarded.
Others like Nonlinear Labs, Entropy & Sons, Mellotron, Bome Software, Kilohearts, Enjoy Electronics, Synclavier, Casio, Kawai, …
More no doubt.
I have been seeding various specific threads with references to NAMM and you can post to those threads or post here.
