Nopia Update 3
video upload by Martin Grieco
"The pieces start coming together.
After 2+ years of development. Meet Nopia MK1
We’re super grateful for living the dream of engineering this instrument to the highest level possible. Fascinated by the thought of each of you playing it.
Nopia is a semi-modular harmony generator. It features an onboard multitimbral sound engine, a hybrid of sampled instruments and onboard virtual analog synths. A 5 step effects chain, dedicated per module MIDI outs, multitouch strum plate, the list goes on! You’re welcome to visit our refreshed website nopia.io and check out the final spec sheet if this is something you’re curious about.
Muchas gracias amigues!"
New Open Source Virtual Pipe Organ Project: Rusty Pipes
This one is in via DS:
"Hey Matrixitians!
I'm writing in to announce a new MIDI-controlled Virtual Pipe Organ software called "Rusty Pipes".
It's a sample-based organ synth with support for GrandOrgue and (unencrypted) Hauptwerk sample sets. It features 32 bit internal audio mixing, full MIDI support with extremely flexible channel routing, integrated audio and MIDI recording of performances, convolution reverb, and an innovative sample streaming mode that makes it possible to play very large sample sets with a minimal amount of RAM, yet without increasing latency!
Other unique features include a REST API for things like pulling stops - great for people who like to build physical consoles - and optional text mode support (via Ratatui) which makes this ideal for running on headless setups or on a RaspberryPi.
Rusty Pipes is a clean-room implementation written 100% in Rust, available free and open source under the GPL v2. Version 1.3.0 supports over 20 languages including Latin and Klingon, and is available for Linux, Mac and Windows. Debian and Arch (AUR) packages are provided as well.

"Early British classic with that gritty, punchy analogue character.
Recently serviced: every pad triggers reliably; no noisy pots.
Original flat-pack box included. All-original hardware.
Serial (no. 242) on chassis; “Made in England” plate intact.
Set a tempo, balance the per-voice levels, and you’ve got a solid groove in seconds—no menus, no programming detours. The tactile pads invite quick ideas (fills, accents, breaks) and the adjustable pad sensitivity lets you dial in the “human” feel that helps parts sit in a song. Its distinct British analogue tone layers well with samplers/DAWs: track it straight in for gritty loops, one-shot it for kits, or re-amp it through pedals for textures. It doubles as a dependable writing click with character, so riffs and basslines arrive faster.
Fast, hands-on layout. Front-panel rotary controls are primarily per-voice level/volume (plus master TEMPO and LEVEL).
Pad feel is responsive; use the rear trimmers to dial sensitivity for dynamics or hard, machine-tight hits.
Multiple 1/4" jacks along the top panel for audio connections (see close-ups).
Power: 9V battery operation or 9V DC mains adapter (PSU not included).
Condition
Fully working. Pads all trigger; sensitivity trimmers on the underside let you set your preferred feel. Cosmetic wear from age and use: scuffs/scratches and some discolouration; a few rubber feet missing (see photos).
Included
MPC the KIT unit
Original flat-pack/knock-down box"

Selmer Companion Electric Reed Organ SN 152

"Selmer Companion reed organ from the 60s. In tune and wonderfully “parlour-harmonium”: bright, reedy mids with a gentle breathiness on the attack, then a steady, organ-like sustain from the blower. The chord buttons give an instant drone bed with that slightly nasal, woody timbre that cuts through without ever getting harsh. Think small chapel/folk harmonium vibes—perfect for drones, hymnal pads, psych-folk textures, lo-fi soundtrack cues, and vintage pop hooks. Hear it in the demo (skip to last photo). Typical vintage tuning and keybed feel; expect minor variance vs modern concert pitch.
Features
Classic electric reed organ with compact keyboard and built-in blower/speaker
Left-hand chord section: Major & Minor buttons (C, G, D, A, F, B♭) for instant accompaniment
On/off/level control, integrated flip-up music rest in the lid, suitcase-style cabinet with carry handle 1960s/70s Italian vibe: gold fascia, cream case, and period hardware
Sounds exactly like you want a small electric harmonium to sound—see the demo"

"Serial Nº 21196
Italian-made CRB “Diamond” Cavendish Combo 30 in remarkable condition for its age. Classic combo-organ tones plus a built-in “mini-band” (bass + drums) make it a fun, self-contained writing and performance machine. Built in Ancona under CRB’s Diamond/Cavendish line.
Organ section: Flutes, Clarinets, Reeds, Strings
Presets: Piano, Spinet, Harpsichord
Effects: Sustain and Vibrato (both sound great)
Mini-band (auto-accompaniment)
Drum patterns: Waltz, March, Tango, Bossa Nova, Samba, Slow Rock, Boogie, Disco — all with variable tempo/volume; very much in the vein of early CR-series drum machines.
Bass accompaniment with automatic chords, Free 1-Finger, Memory, and chord quality switching (Major default; Minor/7th via yellow/green buttons).
External output, headphone out
Expression pedal input
Built-in speaker that’s quaint yet surprisingly punchy
UK mains power - we can include a step-up/step-down transformer on request so you can use it in your country without modification, just ask for details."
