Hello All, I'm coming back to midibox after a long break. I have a PIC based core module and some DIN boards left over from a project about 10 years ago. My new project is to build a custom Hammond style controller. I have a Fatar TP80 61 keybed for use. I plan to build a DIO Matrix module and an AINSER64 for drawbars and such. Am I able to use the PIC based core I have for this, or do I need to build one of the new cores? Thanks!

Hey all! First of all, I'm new to the forum and have already learned a lot over the last day, so thank you for that. The reason I am writing is because I have recently managed to acquire a completely new keybed of the type Fatar TP/40GH. Managed to buy it very cheap at an auction from a music store that went bankrupt. The keybed is originally intended to be a spare for a Nord Piano 3 & 4 (that's why I think it's a GH, the package only specifies "TP/40" and the store has, as I said, gone bankrupt so i can't ask...) My plan is to turn the piano bed into a master midi keyboard like the Doepfer PK88, but I'm pretty unsure how. I do not know if the electronics in the keybed are from Nord or from Fatar. Regardless, I'm not sure how I would proceed. Is there anyone here who can help me transform this amazing keybed into a midi keyboard? This link will forward you to an album with multiple images of the keybed: https://app.photobucket.com/u/gameboygeek/a/db091580-ac08-4523-a37d-f666ff5c11a5/p/9f5fe070-7482-496a-a487-faeca42c0b6f Three cables run from the circuit board. The only external input i want is a sustain pedal. Briefly about me: I know how to solder and have previously worked with circuit boards. Have a master in information systems so will probably understand the process. However, I'm not very good at coding if needed. Thanks!! P.s. apologize if I posted this in the wrong place, as I said is new to the forum ( but I have read the rules). Pp.s. I've read this post but need more help.

Hi everybody, my name is Florian (aka Thoskan) and I live near Toulouse in France. First of all, Thanks to all of you for sharing all this documentation about the project MIDIBOX KB. Initially I wanted to buy the controller LMK2+ alone without the keyboard, but Doepfer wanted to sell me 500 euros. So I refuse and opt for the MIDIBOX project, more interesting, configurable and also much cheaper. My project is to midify a keyboard Fatar TP/40L, and I chose to use MIDIBOX KB, with the CORE_STM32F4 and DIO_MATRIX. I bought the 2 PCBs from https://modularaddict.com and I also printed the FantomXR PCB (Fatar keybed adapter http://www.midibox.org/dokuwiki/doku.php?id=fantomxr) at OSHpark. Thank you FantomXR for this missing piece to my project. For the moment, i just want to connect the keyboard (2 micromatch of 20 pins ), a sustain pedal and 2 yamaha FC7 pedals to control volume and fx. I bought all the components from https://www.reichelt.de/ from the orderlist. Moreover, the STM32F407G-DISC1 is available here: https://www.reichelt.de/?ACTION=3;ARTICLE=219363;SEARCH=STM32F407G-DISC1. It is a little more expensive than at Mouser but the shipping costs are lower (20 euros at mouser vs 5 euros at reichelt). I look forward to receive all these components and I hope that i will solder very soon. I will share every step of the construction, that's why I created this topic. I hope I will not have too many questions. Thank you Thorsten for this great project and for your generosity.

Hello all, I've build my core stm32F4(fantomxr pcb) + diomatrix + fatar adapter to connect my 88 keyboard. I installed midibox kb and connected everything, but i can't output any midi, so i guess i did something wrong :) I tried the virtual keyboard and i didn't receive any midi input in my daw, so i was wondering if my setup was correct, it seems midibox kb is loaded correctly(cf picture). Here's the setup of my midibox kb: [13020.190] kb 1 debug on [13020.190] kb 1 midi_ports 0x0001 [13020.190] kb 1 midi_chn 1 [13020.190] kb 1 note_offset 21 [13020.190] kb 1 rows 12 [13020.191] kb 1 velocity on [13020.191] kb 1 release_velocity off [13020.191] kb 1 optimized on [13020.191] kb 1 dout_sr1 1 [13020.191] kb 1 dout_sr2 2 [13020.192] kb 1 din_sr1 1 [13020.192] kb 1 din_sr2 2 [13020.192] kb 1 din_key_offset 40 [13020.192] kb 1 din_inverted off [13020.193] kb 1 break_inverted off [13020.193] kb 1 make_debounced off [13020.193] kb 1 break_is_make off [13020.193] kb 1 delay_fastest 50 [13020.194] kb 1 delay_fastest_black_keys 0 [13020.194] kb 1 delay_fastest_release 150 [13020.195] kb 1 delay_fastest_release_black_keys 0 [13020.195] kb 1 delay_slowest 1000 [13020.195] kb 1 delay_slowest_release 1000 [13020.196] kb 1 ain_pitchwheel off [13020.196] kb 1 ctrl_pitchwheel 128 (PitchBend) [13020.196] kb 1 ain_pitchwheel_inverted off [13020.196] kb 1 ain_modwheel off [13020.198] kb 1 ctrl_modwheel 1 (CC) [13020.198] kb 1 ain_modwheel_inverted off [13020.198] kb 1 ain_expression off [13020.198] kb 1 ctrl_expression 11 (CC) [13020.199] kb 1 ain_expression_inverted off [13020.199] kb 1 ain_sustain off [13020.199] kb 1 ctrl_sustain 64 (CC) [13020.205] kb 1 ain_sustain_inverted off [13020.205] kb 1 ain_sustain_switch off [13020.205] kb 1 ain_bandwidth_ms 0 [13020.205] AIN Calibration Mode disabled. Then i wanted to check if my diomatrix was ok so i connected I1 to O1 on J3 to check for midi input, but i did not receive anything(no data in mios input). Is there a way to troubleshoot easily diomatrix ? or some tension to check on the core stm32F4 , i've checked my soldering and connection with a multimeter and everything seems ok. Thanks!

Salve, ho iniziato un progetto difficile: scollegare la tastiera fatar tasti pesati del 1993 dal digital piano GEM e creare una master keyboard midi USB leggera- Qualcuno ha dei riferimenti esistenti ? ciao antonio
