  1. Jeannie can Wavetable I integrated the Wavetable Oscillator from Mutable instruments Braids into the Jeannie. The wavetable can be modulated with two parameters A and B. Youtube: WTX4 and little LFO modulation to wavetable position
  2. Neue Jeannie Preview Beta Test-Ver. 2.81 Added more polyhonic synthesis from Mutable Braids and Shruthi Synthesizer Braids VOWL: low-fi Vowel synthesis. PRM_A : formant, PRM_B : formant_shift Shruthi ZSAW: Phase-distortion sawtooth with filter sweep Shruthi ZSYNC: Shruthi ZTRI: Shruthi ZRESO: Shruthi ZPULS: Shruthi Chrushed_Sine: Braids CSAW: no functions at the moment Braids VOSM Sawtooth with 2 formants. PRM_A : formant1 frequency, PRM_B : formant2 frequency Braids TOY Low-fi Circuit-bent sounds. PRM_A : sample reduction, PRM_B : bit toggling Braids SuperSaw: Swarm of 7 sawtooths, PRM_A: Detune, PRM_B High-pass filter Braids ZLPF : Direct synthesis of LP/Peaking/BP/HP filtered waveform Braids ZPKF : PRM_A: Cutoff frequency, PRM_B: Waveshape Braids ZBPF : Braids ZHPF : Youtube: https://youtu.be/SCL5GZZQ7MU Github: https://github.com/rolfdegen/Jeannie-Open-source-Synthesizer Greetings from germany.

  4. I'm building wooden side panels for Jeannie. My beautiful office has been transformed into a carpentry workshop. And who cleans up afterwards.. (: Jeannie with self-made wooden side panels..

  6. There is a new case for the Jeannie.. https://www.ericasynths.lv/shop/enclosures/studio/tubeohm-instruments-jeannie-case/ With wooden side panel looks even better..
  7. I wish you a lot of fun with Jeannie. Large DIY block for the Jeannie and Updates.. Link: https://www.sequencer.de/synthesizer/threads/jeannie-polyphonic-diy-synthesizer.160564/page-46
  8. Hello Alex. Here is a new Jeannie Firmware 2.21 ST7735S version. I hope your display problem is solved :) Change display code in the ST7735_t3.cpp file // Initialization for ST7735R screens (green or red tabs) void ST7735_t3::initR(uint8_t options) { commonInit(Rcmd1); if (options == INITR_GREENTAB) { commandList(Rcmd2green); _colstart = 2; _rowstart = 1; } else if(options == INITR_144GREENTAB) { _screenHeight = ST7735_TFTHEIGHT_144; commandList(Rcmd2green144); _colstart = 2; _rowstart = 3; } else if(options == INITR_144GREENTAB_OFFSET) { _screenHeight = ST7735_TFTHEIGHT_144; commandList(Rcmd2green144); _colstart = 0; _rowstart = 32; } else if(options == INITR_MINI160x80) { _screenHeight = ST7735_TFTHEIGHT_160; _screenWidth = ST7735_TFTWIDTH_80; commandList(Rcmd2green160x80); _colstart = 24; _rowstart = 0; } else { // _colstart, _rowstart left at default '0' values commandList(Rcmd2red); } commandList(Rcmd3); // if black or mini, change MADCTL color filter if ((options == INITR_BLACKTAB) || (options == INITR_MINI160x80)){ writecommand(ST7735_MADCTL); writedata_last(0xC0); _colstart = -2; // only for ST7735S _rowstart = -1; // only for ST7735S } tabcolor = options; setRotation(0); } Greetings from germany.

  9. I found a display with the same problem. I can now try to eliminate the error :)
  10. Mmm.. Protective film for Display ST7735 and ST7735S is normal black or green. Blue is not right !?
  11. The display had a protective film with a green tab ? Oh I saw. It is blue !
  12. Thanks Peter. I have send Zip-File via email :) @TAGalex Mmm.. I think it's a problem with the display initialization. I changed that again. Please try again File is send via email. Greetings. Rolf
  13. Trial version 2.21s for display problem.. Please try this.. Sorry !? I can not upload zip files in the midi box forum. Size of my zip file 1.2MB Error message -200
  14. The OLED display has a different pixel resolution and is not supported in the Jeannie software.
  15. Ok I understand. Then we try to adapt the software for you. But it can take a while. I need your email and will send you the software. I need a picture from display backside. Thanks. Greetings from germany :)
  16. Sorry.. Your display is not compatible with Jeannie. Please use the original display type ER-TFTM018-3 from buydisplay.com. Link: https://www.buydisplay.com/st7735-1-8-inch-color-tft-display-module-spi-128x160-arduino-raspberry-pi Greetings from germany. Rolf
  17. Hi dear synth fans. The Jeannie can now stereo. I reprogrammed the voice distribution in the Jeannie a bit. The eight voices can be distributed arbitrarily in the stereo panorama. In addition, there is now a Unison and Mono mode. Voice distribution in Poly mode: 1.Voice Left 90%, Right 10% 2.Voice Left 80%, Right 20% 3.Voice Left 70%, Right 30% 4.Voice Left 60%, Right 40% 5.Voice Left 40%, Right 60% 6.Voice Left 30%, Right 70% 7.Voice Left 20%, Right 80% 8.Voice Left 10%, Right 90% Voice distribution in mono mode Mono: middle voice Mono-2: 1st voice left, 2nd voice right Mono-3: 1st voice left, 2nd voice middle, 3rd voice right Mono-4: 1st Voice Left, 2nd Voice Left to Center, 3rd Voice Right to Center, 4th Voice Right Mono-6: 1st voice left, 2nd voice slightly left to center, 3rd voice slightly more left to center, 4th voice slightly more right to center, 5th voice slightly right to center, 6th voice right The whole thing can be spread from mono to stereo with the PAN control :) The distribution of votes in Unison mode is still being worked on.

  18. Hallo Alex I think the display is not the right type. Hence the display error. The correct display type: https://www.buydisplay.com/st7735-1-8-inch-color-tft-display-module-spi-128x160-arduino-raspberry-pi But you can ask tubeohm.com if he sells a piece. Happy Easter from germany. Rolf Jeannie DIY Project: https://www.sequencer.de/synthesizer/threads/jeannie-polyphonic-diy-synthesizer.160564/
  19. Jeannie has new features. Added a 3rd LFO and all LFOs have 64 waveforms.Small video about AMP modulation with LFO 3
  20. SysEx Dump works now. See short video.It was a bit more complicated than I thought. First, conversion routines had to be developed for all 212 parameter values in the Jeannie, which convert 8/16-bit integer values and 32-bit floating-point values into a 7-bit format for the SysEx dump. The same had to be converted back again.This was followed by functions for the transmission and reception of SysEx data. Last but not least, a simple menu for operation had to be developed. The transmission path is selected with Destination (Midi or USB)DUMP type is either a patch or a bank.DUMP-Bank sets the bank (A-P) for transmission or reception.Source is either the patch no. or when receiving the space in the selected patch bank.SYSEX-DUMP is set to send or receive SysEX data.The "Load/Save" button starts transmission or reception.A progress bar shows the progress of the transfer.
