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"

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 www.yusynth.net
The full description of the Strings-Synth you'll find in the first Strings-Synth
Video"

The analog Choir/Strings-Synthesizer 2.0. Introduction, Plans and Circuits

Published on Jan 26, 2020 Andreas Remshagen

"This is another Introduction and Description of an DIY-Device that i have built. Its the second Version of the analog-Strings Synthesizer i have built before. It has 12 Oscillators parted in 4 Strings-Groups that can be freely tuned in Chords or Octaves and controlled over a CV-keyboard.

There is also a Choir-function based on the VP330-Filter. The Circuits are from Roland (Redrawn by Chok), Ray Wilsons MusicFromOuterSpace and from Yusynth.net

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."

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"

The DIY Analog-Stringsynth Module/Stringmachine #002

Published on Apr 24, 2018 Andreas Remshagen

"Runs now in better performance. All 12 oscillators have a better Tempco and a better Exponential system. Very stable tuning over 5 Octaves. Runs through a moog-filterclone, analog adsr, vca and a alesis-midiverb4"

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]

The DIY Analog-Stringsynth Module/Stringmachine

Published on Jan 21, 2018 Andreas Remshagen

"A short Demonstration of a DIY-Completely analog String-Synth Module. The Module has 4 Channels with 3 VCO`s in each Channel.
It is completely driven by 12 VCO's. The 4 Channels can be controlled in 4 parts or all together by one controller. Each Channel
has its own output and there is one Multi-Out for all Channels together. The Module has a built-in Vibrato Effect.
Each VCO is based on the Sound-Lab Mini-VCO Cirquit designed
by Ray Wilson from MFOS. I took out the Sawtooth-part from this Cirquit. All 12 VCO`s have Tempco for better tuning-stabilisation."

The VP 330 Human-Voice-Filter-Clone Test

Published on Jan 15, 2020 Andreas Remshagen

"I build a Prototype from this Filter using the Circuit in the Link below.
This 7 Filters were built in the famous Roland VP-330 and gave him the
Vintage choir-sounds. Here i used the Filters to test each one
with its own Potentiometer. I didn‘t use the HV-330 compander from Jurgen Haible
that is shown in the right part of the Circuit.
The right combination of each Filter makes the characteristic voice-sound
The Sound-Source ist the Strings-Synth i have shown in a video before.
It feeds the Filters with 12 Sawtooth-Oscillators

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."

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)"

Analog Arpeggiator / Groovebox/ Synthbox with Yusynth Metalizer

Published on May 8, 2019 Andreas Remshagen

"A Demonstration of another Synthesizer-Component i`ve made.
It Incudes 4 VCO`s, each contains Square/Sine/Triangle and Saw-Wave. Every Wave can be mixed into the Main Signal.
The VCF is a Steiner-VCF. Two ADSR drives the VCF and the VCA.
The Metalizer can be feeded with each Waveform that is mixed to
the main Signal. The internal clock drives 4 switchable arpeggiator-sections. the arpeggiator can be set from 1 to 10 Steps.
Internal clock and external clock is possible and there is a gate-out. In the arpeggiator-section i added an "Akzentuator", it gives out an adjustable Accent on selectable positions (1-0-1-0; 11-00-11-00; 111-000-111-000 etc) The accent sets the VCF frequency.
The box can also be used as a normal analog-synthesizer with each VCO-CV in and a master/all VCO-CV in

VCO, VCF, VCA and Metalizer-Design comes from Yusynth (www.yusynth.net)
ADSR-Design comes from Rene Schmitz
(www.schmitzbits.de)
The Arpeggiator and the Akzentuator are modified 4017 countercirquits modified by myself"

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:

12 Oscillators on a Stripeboard in -2 Minutes

Published on Dec 28, 2019 Andreas Remshagen

"A short Video from the Construction of 12 oscillators on a Stripeboard
for a compact version of the Strings-Synth i did show in the Video before. [posted here]
The difference ist that this Device can switch to Rectangle-Waveform.
I planned to make an analog-Choir-Synth from this Device but i haven’t found the right
Filter for it- so is sounds actually like the Strings-Synth. Maybe someone has an idea
for creating choir-sounds?
