Hey Rolf, this sounds fantastic. Would love to see a knobby XT version as well!
Soo Good !
Everytime you post a video I love the development and the growth of this synthesizer. When it's time I would love to buy it.
I hope in two months you can buy "Jeannie" with a case at TubeOhm.com.
Jeannie Kits available on tubeohm.com www.tubeohm.com/ Jeannie DIY blog: www.sequencer.de/synthesizer/threads/jeannie-polyphonic-diy-synthesizer.160564/

Wolfgang Palm would be proud. Excellent job! Looking forward to seeing the kit.
Thanks :)
Wow! that sounds awsome. I will definitely have to build one of these. I did build a Tsynth a while back, boards were out of stock so hand wired everything onto strip board. might not look too pretty but workd great....
Thanks. We have also built in special features. Jeannie has a 24Bit Effect DSP with 15 programs, analog bass boost and BurrBrown 32Bit DAC PCM5102A for better sound.
Sounds great. I have a pcm5102 module I was using with an esp32 for internet radio.
Kudos. Not an easy job!
I love this and I want to build one.
So awesome!!!
i like it..respect
Can I make a sample library out of these?
Muito Bom trabalho Rolf. Parabéns por compartilhar.
Very impressive

Klingt super nice! Ich würde auch gerne einen haben :) Aber hoffe der wird nicht so überteuert wie der rest bei tube ohm.
Ist ja DIY. Du kannst den kompletten Bausatz bestellen oder nur Platinen oder einzelne Bauteile und dabei Geld sparen. Außer dem Display (kommt aus China) bekommt man die Bauteile bei fast allen großen Elektronic Läden.
Es gibt verschieden Bausätze. Du kannst nur die Platinen kaufen und selber löten. Dadurch kannst du bis zu 50% der Kosten einsparen.
Is it open source?
Are there any good resources / applications to create the GUI on the OLED?
I have followed steps to create a Teensy Synth and wanted to add a screen to make it a little more interactive
I will publish the source code on Github soon. I use the display driver ST7735S from Arduino lib
@@rolfdegen1806 Thanks a lot!
I was more wondering how one goes about designing a custom Teensy GUI? Is there an application I can use to visually design the interface which can be converted to code?
@@danielpoole6704 No, unfortunately not. I have everything individually with text and graphics function, for example. Draw rectangle, lines and points programmed
Tolles projekt! Wird die Firmware für den Teensy open source sein, damit man eigene Änderungen durchführen kann (bspw. eigene Potis für bestimmte Parameter)?
Ja die Firmware ist open source und wird später auf Github verfügbar sein. Es gibt auf der Jeannie Platine noch einen Expansion Anschluss. Das sind drei analoge Eingänge und ein Schieberister Ausgang. Darüber lassen sich zusätzliche Tasten, Regler oder andere Dinge steuern und abfragen.
Sounds great, needs a case, maby make one out of wood.
we have an blue case. www.tubeohm.com
Does this use the ladder filter at all? I'm building a synth using a teensy 4.0 and was wanting to use the ladder filter and was hoping to make it polyphonic. The documentation says the ladder filter is more numerically intensive but I'm not sure what that means in my case. I'm hoping to have 2 LFOs, 3 Envelopes and at least 8 voices of polyphony. I don't need any effects except for maybe a chorus. Would a teensy 4.0 be able to handle that?
You can use Ladder Filter or State Variable Filter. Ladder Filter is LowPass only and has nice resonance. State Variable Filter has LP/HP/BP . Teensy 4.0 should work with 8 voices. Has enough RAM and flash memory. Jeannie has many settings. Look at here: www.modwiggler.com/forum/viewtopic.php?p=3753694&hilit=Jeannie#p3753694
@@rolfdegen1806 Yeah, I've messed around with the state variable filter but I like the sound of the ladder filter better. I'm kinda going for a polyphonic model d sound. Though if it's too much for the teensy to handle polyphony with the ladder filter I'll switch to the other one.
@@System-1541 Here my example for ladder and state variable filter ruclips.net/video/TWzHH8oTYs8/видео.html
Can i purchase one fully assembled?
Yes. There are trusted builders. Please ask tubeohm.com.
Is the i2s output 32bit per channel L/R?
No. The Teensy 4.1 Audio Lib ist 16Bit. The integrated audio effect IC SPN1001-FV1 has 24-bit resolution. DIY Blog www.sequencer.de/synthesizer/threads/jeannie-polyphonic-diy-synthesizer.160564/post-2601056
So would like to buy the diy kit but wont post to UK :(
Its alot of work to build it.
@@HOLLASOUNDS building it not a problem 👌
How did you do the presets
