"You want to build a synthesizer yourself ? Preferably polyphonic ? And with effects like reverb , delay , chorus .....
Then have a look at this video. Jeannie is an brand new 8-voice polyphonic DIY synthesizer.
During the development we made sure that the instrument is relatively easy to build. But, component know how and soldering skills should be present. Then nothing stands in the way of a successful DIY.
This video gives a short overview of the individual construction steps. After that, some sounds are presented.
Approx. 400 sounds are currently available in 3 banks.
15 sound banks with 128 sounds each can be managed.
800 different waveforms and an effect DSP round off the synthesiser kit.
The synthesiser is freely programmable, the software open source.
Features: 2 DCOs/800 waveforms for each DCO , three LFOs with /64 waveforms each ,
two ADSR generators /lin/log/exp, FX DSP for effects like reverb , delay, chorus , phaser , pitch shifter .... and much more.

Du möchtest einen Synthesizer selber bauen ? Am besten polyfon ?? Und mit Effekten wie Hall , Delay , Chorus .....
Dann schaue dir doch dieses Video an. Jeannie ist ein 8 stimmiger polyfoner DIY Synthesizer.
Bei der Entwicklung haben wir darauf geachtet das das Instrument relativ einfach zu bauen ist . Aber, Bauteil know how und Lötkenntnisse sollten vorhanden sein. Dann steht einem erfolgreichen DIY nichts mehr im Weg.
Dieses Video gibt einen kurzen Überblick über die einzelnen Bauschritte . Danach werden einige Klänge vorgestellt.
Ca. 400 Sounds stehen aktuell in 3 Bänken zur Verfügung.
Es können 15 Soundbänke mit je 128 Sounds verwaltet werden .
800 verschiedene Wellenformen und ein Effekt DSP runden das Synthesizer Kit ab.
Der Synthesizer ist frei programmierbar, die Software open source.
Features: 2 DCOs/800 Wellenformen für jeden DCO , drei LFOs mit je /64 Wellenformen ,
zwei ADSR Generatoren /lin/log/exp, FX DSP für Effekte wie Hall , Delay, Chorus , Phaser , Pitchshifter .... und vieles mehr ."

The Jeannie DIY Synthesizer
What is it anyway ?

Jeannie It is an 8 voice polyphonic DIY synthesizer, 2 oscillators, 2 envelopes, multimode filter, waveshaper,2 LFO, ring, sync,FM , Xor,or, and a step sequencer . The oscillators have 945 different waveforms each. More than 2000 sounds can be stored on the SD-Ram card

*** Very new are the 10 adjustable waveshaper behind the filter. This gives . The synthesizer contains a digital FX, but it can be extended with up to 14 different effects (programmable and storable) via an additional board containing a DSP.

The project is currently on https://forum.pjrc.com

"I am currently developing a new DIY synthesizer based on a Teensy 4.0 Boards. The synthesizer will look similar to the small Shruthi Synthesizer from Mutable Instruments. Compared to the Shruthi this synth will be polyphonic, have a color TFT display and other things like a 2Channel 16Bit DA-Converter, digital and analog filters. The housing and board format is similar to the Shruthi (see picture). That's why for the DIY Project I also created the Name 'Shruthi 2' selected."
