Waldorf Microwave XT Rackmount Wavetable Synthesizer - Nextel Orange w/voice and display upgrades

Note: links to listings are affiliate links for which the site may be compensated.

via this Reverb listing

"I picked up this beauty a couple years ago thinking I'd be the next Industrial Noise Super Star, but turns out Blush Response has the job covered. I installed antelope's 30 voice upgrade module and also replaced the old LED with another I got from the Isle of Mann on eBay that looks wonderful! (It's not OLED, but something else). Sounds great, knobs are faded, but everything seems to be working great. A fabric dust cover has been on it since owning and. There is a third party power supply included that wouldn't be my first choice, but it works just fine. It's a 30 year old synth and has some road scars, and one of the rack ears is a bit bent. The Nextel paint will still abrade your skin if you get too drunk and fall face first onto it. You want minty? This ain't it."

Kawai K5000R Demo

video upload by Panu M Savolainen

"Multitracked demo of Kawai K5000R. Additional reverb Eventide Space and delay has been used. These are factory patches tweaked with Macro controller. Controller looks pretty bad, but is fully working. Synth is missing power button cap, screen is worn and diskdrive won't work (should have usb-reader somewhere). I have owned K5000R without controller but also K5000S and K5000W. Later ones has pretty good keyboards in my opinions...

Whole demo at Bandcamp:"

Field recordings of cicadas, Rhodes Mark II, OP-1 field : Imaginary cicada 2025-08-06 by atnr

video upload by atnr

"Field recordings of a cicada-filled park, Nord Lead, and Rhodes

A piece built from park ambience where cicadas sing—heard against the memory of a summer so hot that, these days, even the cicadas in Tokyo seldom call.

This year in Tokyo the heat has been relentless, and opportunities to hear cicadas have become scarce.

Harmony and melodies are performed on the ‪@NordKeyboards‬ Nord Lead and Rhodes.
The field recordings are re-recorded into the ‪@teenageengineering‬ OP-1 field and transformed using its onboard filter and an ‪@KORG_INC‬ NTS-1 for additional processing."
