video upload by Andreas Remshagen

"Here some Pictures made during the making of my analog Hybrid Tube-Synthesizer. All Sounds are made with this Device. I started in October 2024 and finished in February 2025. I had a lot of fun building it and learned a lot.
The Music was recorded with a Boss RC202 Looper"

DIY Analog Hybrid Vakuum-Tube Synthesizer - RingMod Knob Tweaking

video upload by Andreas Remshagen

"Today i finished the RingModulator of my analog Hybrid Synthesizer and i'm glad to show you some very strange sounds made with this instrument
The circuit of the Vakuum-Tube VCF was made by René Schmitz (www.schmitzbits.de)"

DIY Analog-Hybrid Synthesizer with Rene Schmitz Vakuum-Tube VCF

video upload by Andreas Remshagen

"At first I wanted to build a complete vacuum tube synthesizer but I had problems with the vacuum tube VCO and the correct intonation over several octaves. That's why I decided to build two AS3360 chip VCOs and run them through a vacuum tube mixer. I used Rene Schmitz's vacuum tube filter as the VCF. ADSR, VCA and ring modulator run on AS chips. The envelope curve display is done via a Toyo 6E5 Magic Eye"

I feel Love - Live Version on a DIY Analog Modular-System

video upload by Andreas Remshagen

"A Live-Version of thie famous song 'I feel Love' on my analog Modular
System. This is propably the 1000th Cover-Version of this famous song from Giorgio Moroder and Donna Summer but i see it as a "must have done" for analog Synth-Musicians. As i said its an own Version from this Song and it not depends 100% on the Original but i like to play with this Theme. Enjoy!"

DIY-Analog-Synthesizer for the Pocket

video upload by Andreas Remshagen

"This is a project I've wanted to do for a long time
A complete mini-Synthesizer with midi and analog sound-generation
and analog filters.
It contains a standard midi-keyboard. For the CV-Converting i used an arduino-Nano and a digital to analog chip. VCO: Two AS-3340 VCO with Triangle/Ramp and Rectangle Waves
One Noise-Generator
Sync and Ring-Modulator
VCF: One Steiner-Parker Synthacon Filterclone switchable LP/BP/HP/AP
and one 24 dB AS-3320 VCF
ADSR: Two AS-3310 ADSR
LFO: Two LFO with Sine, Triangle and Rectangle Waveform
One Arpeggiator with 2 and 4 steps
A little Patchfield for different in and outputs"

DIY Sequencer for the Elektor Formant

video upload by Andreas Remshagen

"More Info and Cirquit:
www.remshagen.eu/Formant/Sequencer.htm

I saw this Sequencer for the Elektor Formant in some Vids in the Net - but i couldn't get the original circuit. So i created an easy circuit that is based on the Baby 10- Sequencer. Its a 555-Clock with a 4017-Counter.
The Sequencer can be driven by an external Clock and it has two Gate and CV-outputs.
I connected the Gate and CV directly with the Formants Gate and KOV inputs. If you don't want to make this internal connection then you can do this via the CV and Gate output Jacks."

Popcorn (Gershon Kingsley) -Variation Live on a DIY Analog-Modular System

video upload by Andreas Remshagen

"This is probably the thousandth version of Popcorn, but it's somehow also a must for analog synth freaks like me. It's played live and runs partly via Midi to CV/Gate and partly via analogue sequencer. I described the devices i used in the video. Have fun :)"

Analog Dance Modular Session

video upload by Andreas Remshagen

"a 'Maxi-Version' of a rhythm-based jam with some of my new components i have built. The devices are:
- Orchestrion Strings/Choir Synth (Described in previous Video)
- Analog Drumbox with 4 DS7-Clones and two Noise-based HiHats
(The Drumbox is either driven by the "Trigger-Randomizer"-Module"-its an arduino-based 5-Channel Randomgenerator in combination with 5 analog AND-Gates connected with a random-signal and the clock-signal for each Gate and each Gate is for a Drum. In this song the HiHat and the two analog Congas are in Random. So there are additionally Fill-ins to the normal static rhythm)
-Bass-Synth 2.0 (two Saw/Sine VCOs with Steiner-Parker VCF, YuSynth
Metalizer and Akzentuator
-Elektor Formant
-Analog Groovebox (Described in previous Video)
-Two YuSynth VCO with Steiner-Parker VCF for Keyboard Solo
-Two Polyend Poly Midi to CV-Converter
-Two Alesis Midiverb4 for Reverb and Delay
-My free Flowstone-Based sequencer-Software (Described in previous Video)" [posted here]

Atlantis ( Modular Live + Keyboard-Solo)

video upload by Andreas Remshagen

"Inspired from the atmospheric sound of my new Strings/Choir-Synth
'Orchestrion' i made this Live-Session.

at first you slowly dive into the underwater world and then drop more and more into the depths. Suddenly you approach the ruins of Atlantis and you still have the impression that everything is alive there. Finally, you leave the ruins back in the depths of the sea and move away again.
Many LFOs, Filters and Sequencers were used for this Performance"

Orchestrion-a DIY analog String/Choir machine

video upload by Andreas Remshagen

"Complete Description and Circuits:

www.remshagen.eu

A Strings/Choir synthesizer based on 12 oscillators with the AS3340 chip. I have chosen this VCO to get a very stable tuning over the octaves.

Each oscillator can be tuned individually. 3 oscillators are grouped together. There are 4 groups and each group has its own CV-1V/Oct input.

With an appropriate controller, the device can be played polyphonically in 4 voices.

There is a CV input for all VCOs at the same time

There is an adjustable ensemble effect that is always split between the 3 VCOs in a group

The entire device contains individual modules.

Strings and Choir can be mixed with a 5K Lin - Poti.

A separate saw-output can be connected to an external Filter or Resonator. It can be connected back

to the VCA-input

Delay is an option i didn't built in at this time"

Clouds-Two DIY analog String Machines

video upload by Andreas Remshagen

A Live-Performance with my two DIY String-Synths
I used the Strings-Synth and the Strings-Choir-Synth 2.0
The Melody comes from the Elektor-Formant and the Drums are from my analog DS7-Clone Drumbox.
All Synthesizers are driven from my Flowstone Sequencer-Software and two Polyend Poly Modules
The effects are from the Elektor Formants Noise routed through a Steiner-Parker Filterclone and Ray Wilsons Noisebox (Musicfromouterspace.com)
All String-Machines are also based one Ray Wilsons cirquits
The Solo-Synth plays the YuSynth-VCO. The ADSR is connected with
the VCO`s CV in and gives the character of a Japanese Flute

Andreas Remshagen Live Sequencer Software for Free

video upload by Andreas Remshagen

"Download: https://drive.google.com/file/d/1C1uB... This is the Sequencer-Software i made with Flowstone for my Live-Performances. It should run on every Windows-PC and is written to control Midi to CV-Devices like the Polyend Poly. It can Handle two different Devices with 8 Midi-Channels. Maybe you can use it for your own Performances. It is completely free so i dont can give a guarantee for everything. If you have the Flowstone-Software you can edit the source- code-file called FL-Sourcecode in the Zip and change the Sequencer as you like! This Sequencer works extremly stable in performance and Timing I normally work with analog sequencers but a Sequencer with the complete Functions like this Software-Sequencer would take up more space in my room than i have"

a free Sequencer for driving multiple Analog-Synths made with Flowstone

video upload by Andreas Remshagen

"Download: https://drive.google.com/file/d/1Qhf3...

This is a Midi-Sequencer i made for driving my Analog-Synths with a small Asus-Netbook connected to a Polyend Poly Midi to CV/Gate Converter.

I work with different Versions of this Sequencer and its a good compromise for me driving analog-Synths with a digital component for live-performances.

The Sequencer is made for the Asus eee-PC's resolution but it should work with every Windows-PC.

Its has:
1 to 16 Steps
4 Step-Sequencers with 2 Octaves-Grid, Clock and Step-Divider
Separate Midi-Channel selectable for each sequencer.
On/Off switch for each sequencer exceps the clock-sequencer
2 clock/Gate-sequencer
1 gate on first step option for reset drum-machines etc
Usb-Device selector
load/Save-Function"

StringQuartet – Free VST/Standalone Strings/Choir-Synthesizer/Stringmachine

Andreas Remshagen

"Download Link: https://drive.google.com/file/d/1i8Vc...

A nice virtual version based on the technology of my Strings/Choir-Synth 3.0 Shown in a vid before. I tried to get as close as possible to the original. It also has 12 Oscillators in 4 Groups. Each Group is detunable and has its adjustable Volume. Also the whole Machine has an adjustable Ensemble-Function and a Chorus. A Volume and Filter Envelope is included. Like the Original you can Mix with the Strings/Choir-Knob. The StringQuartet is created with Flowstone and the Demo i played with the PC-Keyboard. Please Remember: This free Software is not perfect as commercial but it is made with love to the Detail and for sharing. Don’t take shared Freeware to make money. Thanks and i hope you have fun with this virtual device."
