There’s always that debate about which years mark the end/beginning. Officially the 2nd millenium ended on Dec 31, 2000 rather than 1999, but then 2020 will be part of the '20s…
Anyway. My favorite musical gear acquired in 2019, in no particular order
16n Faderbank – I got it mostly for Teletype/ER-301 control, but I find myself using it as a MIDI controller (mostly for mix levels) and CV controller (also for mixing but also timbres) more than anything else. Once in a while I use it to turn Teletype into a hands-on sequencer. I stuck a couple strips of whiteboard tape on my desk in front of it to act as a scribble strip.
Reface CS – it’s not a mind-blowing synth, but it’s simple and fun. Fun is important! I have a Elektron Analog Drive basically surgically attached to it to give it some extra ooooomph.
Bitwig Studio 3 & Expert Sleepers ES-3 + ES-6 – as close to an ideal setup for me as possible. Before, I was using Maschine as my DAW despite not doing drum/sample-centric stuff anymore, because I was used to it. Now I really think of my modular as a hybrid hardware/software setup with a very permeable membrane.
Lyra-8 – I love this thing. It is bursting with character, the sound and feel suit my music so well it almost feels like it was designed for me and yet also designed to expand my horizons in just the right ways. The things that are “missing” or “wrong” with it are as lovable as the rest.
Mimeophon – I’ve said before, this module seems like it was designed based on a list of features I wrote earlier in the year about my ideal delay, but in stereo and with Make Noise’s own twists.
Plugins – Valhalla Delay, Wavesfactory Cassette & Spectre, DDMF MagicDeathEye.
