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:

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:

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 (
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: 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


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

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

Andreas Remshagen

"Download Link:

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."

The DIY Strings/Choir-Synthesizer 3.0 Demo

Andreas Remshagen

"This is the second Modification of my DIY Strings/Choir-Synthesizer
You hear 15 different Sound-examples repeating the same theme
- Please write in the comments which is your favorite!
Each Strings-Group from the four Groups has its own CV-1V/Oct in
and each is connected to one CV-out of a Polyend Poly2. So there is a
4-voice-Polyphony playable over a PC or a MIDI-keyboard. I added a
Gate-in that is connected to the poly2's first gate-out. The gate in drives
a variable Attack-Release for the whole Strings.
one Oscillator in each Strings-Group is tuned one Octave higher
for a larger sound
The Effects i used are a
modified behringer Vintage-Phaser (i'll explain in my next vid) and a
Yamaha FX-500.
the Settings of the FX-500 are:

REV + MOD on,

REV: TYP: DLY, MIX: 50, LVL: +1, L-DLY: 150.0, R-DLY: 300.0, FB: 1, L=R

MOD: TYP: SYM, SPED: 0.7, DEP: 80, MIX: 90, LVL: +5

The Attack-Release cirquit i took from Ray Wilsons Noise-Toaster
The VCA circuit comes from YuSynths site
The full description of the Strings-Synth you'll find in the first Strings-Synth

See the Remshagen label below for more.

Jam with Polyend Poly2 and DIY Analog Modular-System

Andreas Remshagen

"I broke my rules and connected my DIY-Analog-Modular System
with the Digital world. I bought a Polyend Poly-2 Midi to Multiple Gate/CV
converter and experimented with different ways driving my Modular-System.
Each Midi-Channel can drive one Synth in its Gate and CV so i could program
a polyphonic example including different analog-Drums, analog groove-Synths,
a String-Synth and a Bass-Synth. I took my old Asus Eee-PC and worked with
the good old Voyetra-Dos Sequencer in a DOS-Box under Windows7 32bit
(DOS only wouldnt work with the Polyend over USB)"

The Arduino-Solina V2.0

Andreas Remshagen

"I experimented with Arduino-Synthmaking and found an Arduino-Solina String-Synth Device running with Midi made by Morocco Dave and Jan Ostman. I made a modification by adding a second Arduino for building a Stereo-Device for a lusher String-Sound.

Yah, i know its not a real solina or a strings synth but i never had build such a Device easier and cheaper.Its a nice Solution for using strings-effects. I only use the clean sound in this video-if you take effects as reverb, delay, phaser and a filter you will get a very nice sound

Here you can download Morocco Daves modified circuit:

The Code you can get ai Morocco Daves Site:

Thanks to Jan Ostman and Morocco Dave for sharing their ideas"
