I would like to thank my customers for their loyalty over the years and hope that you had a lot of fun with my instruments.
Maybe I will write a few more software synthesisers. Maybe Freeware or Demos.
This will then be published on KVR.
The site will remain online for the time being as the circuit diagrams and information may still be required.

TubeOhm's aka Rolf Degan's latest hardware creation was the Jeannie 8 Voice DIY synth pictured. You can find posts featuring it and additional creations via the TubeOhm label below.
"Sound examples of the DIY synthesiser Jeannie with the new firmware V 3.xx.xxx
You already know Jeannie from previous videos. New is now the firmware version V 3.xx.xxx . for Jeannie
This includes various new oscillator models, e.g. from Braids , Shruthi / Phoenix and Ambika ."
"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 ."
Controlled by Arturia's The Factory MIDI keyboard controller.
"Stress test of the filter. No audio in signal was used. All sounds were generated with the filter resonance. A signal generator was only used to control the resonance and the different filter types. The video is handheld with a mobile phone. I thought it would be interesting for you to see what the filter alone can do.
The sound was recorded with a mobile phone."
The SMR4P-Multi contains the best from 2 worlds . First , it sounds warm like the SMR4 and second - 15 different filtertypes like the 4PM. While doing sounddesign it is very helpfull to have a ' swiss knive' VCF. So we implement 15 different filtertypes like 6+12+18+24dB LP 6+12+18 dB HP 6+12 dB BP HP2LP, HP3LP Notch,Phaser, Notch+LP1, Phaser+LP1.
What else we have build in ? There is also a FM posibility, an inbuild VCA , and you can switch the different filtertypes a:) manual or b:) voltage controlled. Inputs: Audio in, Res= resonance contol (0..10 V),Gain(VCA control 0..10V) , Mod (extern) and Cut(V/OCT0..10V) Outputs : VCA and VCF *** VCA, the output singal is contolled in its amplitude by Gain 0..10 v VCF is the direct signal without VCA controll DIY scills : good soldering knowledge , high integrated parts - through hole , no SMT
"Everything is sequenced with the Torso Electronics t-1 and the drum sounds on the Novation Circuit Rhythm are quickly sampled from the Norand Mono.
This wonderfull TubeOhm Jeannie drone pad is sequenced by the t-1 with 4 different Tracks and everything is mixed on the 1010Music Bluebox."
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 FX board is based on a Spinsemi FV-1. At first we wanted to switch off the built-in effects programmes, but some of them are quite usable. We have also programmed 8 new effects.
"First ( and fast) preview of our new DIY synthesizer Jeannie. It is 8 voices polyphonic and has an internal effect chip with reverb / echo / delay etc.
Jeannie is based on the Teensy 4.1 and the FV-1 chip.

"Download the patches here: http://ludotex.net/?page_id=84
Patches (lots of pads, some sequences, weird stuff) I have made the past months on my ambika with 6 SVF cards. Ambika, made by Olivier Gillet of Mutable Instruments, is a DIY digital synth with analog filters and vcas. It's very fun to program because it has a lot oscillators waves, many routings, sequencers.
The board on the one i built is "tubika" from tubeohm.
Added a little Immerse reverb in the mix. 3 voices from the ambika are panned left, the other 3 are panned right, for stereo."

It contains 15 different filtertypes.
It comes as a DIY kit .

There is also a FM posibility, an inbuild VCA , and you can switch the different filtertypes a:) manual or b:) voltage controlled.
Inputs: Audio in, Res= resonance contol (0..10 V),Gain(VCA control 0..10V) , Mod (extern) and Cut(V/OCT0..10V)
Outputs : VCA and VCF *** VCA, the output singal is contolled in its amplitude by Gain 0..10 v
VCF is the direct signal without VCA controll
DIY scills : good soldering knowledge , high integrated parts - through hole , no SMT"
