Donner L1 Synthesizer Inside and Mods

video upload by Maffez Synthmods

"Some easy modifications (Filter FM, VCA boost) and a couple of inside pictures of the Donner L1 synthesizer module. You can see how the alfa par ICs are used for VCO, VCF and VCA, how the whole magnetic keyboard system is arranged and how the ADSRs are digital (not that they soudn any less funky!). All sounds in the demo are from a modified unit."

TOMITA, CASIO & THE COSMO SYSTEM

"TOMITA, CASIO & THE COSMO SYSTEM: Casio collaborated with Casio way back in the early 1980’s to create the COSMO synthesizer which was a huge rack of custom devices and computer system that ultimately became the CZ-101 Synthesizer and FZ-1 Sampler…the first 16bit sampler. From what understand the CZ-101 has in its code something like 64 different waveforms of which only 8 were selected for the CZ. I’ve seen someone post about this and was trying to make them accessible. Phase Distortion synthesis is the “real” FM (again as I’ve read somewhere) and Yamaha’s FM is different though I’m not sure what those differences are. The CZ started my career as a sound designer and remains one of my Top 3 instruments though I use the Virtual CZ soft synth by Oli Larkin. I have my entire collection of sounds from all the way back to 1986 and all the ones used on my “Lost Childhood” albums that were done with just two CZ-1’s run from a Roland MC-500 MIDI sequencer in real time through a Roland R880 digital reverb direct to DAT. A fantastic and classic synth! 🎛️ 👽"

PlantsSystem-PRA32-U Editor

video upload by plantssystem

"I created a definition file for the digital synthesizer 'PRA32-U' by ISGK Instruments for the Renoise scripting tool Guru.
All sound parameters of this synth can be controlled by MIDI Control Change (CC) messages, so the mapping was very smooth. By simply associating each parameter according to the CC number, you can intuitively create sounds in real time in Guru.

This allows you to use the PRA32-U in Renoise just like a software synth, making the fusion of trackers and hardware synths even more comfortable.

It looks like it will be useful for live performances and improvisational sound design."

NINA Multi Track Sequencer 2.1 Firmware Update: Melbourne Instruments Analog Polysynth Groovebox

video upload by Melbourne Instruments

"NINA's multi track sequencer firmware 2.1 is out now, NINA is no longer just a synthesizer — Unlock a standalone groovebox for beatmakers, producers, performers and sound designers. A groovebox for dynamic and expressive performance anywhere - studio or stage. Great for generating quick new ideas or work some amazing complexity into your music. This is all powered by NINA's raw analog oscillators, ladder filter and wavetable oscillator. Not forgetting the revolutionary motorized knobs that snap to life for hands-on, tactile interactive control, now you can feel your sound. Whether you’re crafting beats or complex melodic patterns, this next-gen groovebox workflow unlocks a completely new way to create.

All sounds and patterns in this video were created solely using NINA.

Key Features of the Multi-Track Sequencer:
• 4-Tracks—up to 64 steps with independent length per track, for polyrhythmic sequencing.
• Per-step Automation—front panel parameters can be locked per step.
• Polyphonic Sequencing — up to 12 voices available spread across 4 tracks.
• 64 Noise types — percussive hits, metallic textures, buzzes and digital percussion.
• Motorized Automation— you can see the front panel move, turn automation on/off.
• Time-based features —shuffle, micro-timing, clock multiplication, variable gate lengths, and probability.
• Perform patterns—recall and chain up to 16 patterns.
• Internal Storage for more than 4,000 patterns.
• Save a pattern with all sound and sequencer data in save into a single file.
• Standalone operation— no other gear required. Of course NINA works well with other gear too!
• New features include: timing quantization, clear notes and clear steps.

"Build your own digital synth with PRA32-U × Raspberry Pi Pico!

ISGK Instruments' PRA32-U is a digital synthesizer that uses Raspberry Pi Pico.
The Pico and various circuits can be arranged smartly, making prototyping and modification a lot of fun, and allowing you to quickly put your ideas into shape.
This time I put together everything from MIDI input to sound generation and output, and it was extremely easy to use as the foundation for a homemade synth, and it was a very fun experience to build it."

Overview

4 Voice Polyphonic/Paraphonic Synthesizer for Raspberry Pi Pico 2/RP2350

Built-in Chorus and Delay FX

Controlled by MIDI -- PRA32-U2 is a MIDI sound module

Having the function of writing the parameters to the user programs and the flash

Modifiable with Arduino IDE and Arduino-Pico (by Earle F. Philhower, III)

An I2S DAC hardware (e.g. Pimoroni Pico Audio Pack) is required

PWM Audio can also be used instead of I2S (PWM Audio does not require an I2S DAC hardware)

Prebuilt UF2 files ("bin")

"Digital-Synth-PRA32-U2-Pimoroni-Pico-Audio-Pack.uf2" is for Raspberry Pi Pico and Pimoroni Pico Audio Pack

"Digital-Synth-PRA32-U2-PWM-Audio.uf2" is for Raspberry Pi Pico and PWM Audio

Waldorf Edition 2 - Sound-Demo

video upload by WaldorfMusicChannel

"New Version 2.3.3 available in your 'myWaldorf' account. Attack now native on macOS https://waldorfmusic.com/waldorf-edit...

PPG Wave 2.2V is a virtual reincarnation of its namesake cult classic, coming to prominence with the trailblazing PPG Wave series starting back in 1982.

First resurrected in 1989 with the Waldorf Microwave, today it enjoys a new lease of life in virtual studios on Mac and PC computers. Classic wavetable synthesis is known for conjuring up the feisty analogue and digital hybrid sounds that have graced so many hit records over so many decades.

Attack is a percussion synthesizer powered by an almighty analogue synth sound generator. It transports the trademark sounds of classic Eighties analogue drum machines and the progressive electronic club beats of the Nineties onwards and upwards into truly 21st Century production environments.

As Attack computes all sounds in realtime, users can change any parameter directly.

D-Pole completes the Waldorf Edition 2 lineup as a very versatile filter plug-in with five filter types (lowpass, bandpass, high pass, notch, and resonator), SAMPLE RATE reduction, RING MOD, OVERDRIVE (ranging up to +52 dB), and stereo delay — all in wondrous Waldorf quality!"

Kurzweil K2000RS Rackmount Digital Workstation Sound Module W/Sampling Option

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

via this Reverb listing

Two pics of the inside below.

"Kurzweil K2000RS Rack Synthesizer w_sampling option (V3.87) – classic workstation module, Excellent condition. This unit has the latest firmware (v3.87) and is expanded with 32MB RAM for sampling at 48k. All MIDI, audio outputs, and floppy drive work perfectly. Note: The only issue is the internal FX engine is functioning with artifacts on the main outs only. (common in this run of Kurz units). This doesn’t affect the (8) direct outs and digital I/O, synthesis or sample-playback; Cosmetically, and internally, the rack unit is in fantastic shape. Comes with the original manual (which is considered the bible on how to design your own synth patches and beyond) and loads of floppy disks I've acquired along the way. The K2000RS is a legend – the piano presets are easily mistaken as the real thing considering the world of virtual pianos we have today. 16-part multitimbral, powerful V.A.S.T. synthesis."
