I don't see any reason today to have a separate interface/computer that need to be sync too, to record/play automation data. As you say, modern DAW/computer can handle all this pretty good with advanced protocole, HUI is ok MCU too (the one I use) Just be aware that midi box don't handle the HUI dual CC data used for 10bit fader, so PT user might have problem in the actual state Another route I have to test is the OSC protocole, I have all part here to do an MB_ETH board, just need more time It might not be faster but hope can open more extended bi-directionality and function than HUI/MCU., Regarding fader the TKD I have don't have particularities except the high qualities of conductive plastic track, I have a 10v motor version. I will test again cheap ALPS I have with this "finished" integration, maybe he will react better to digital/motor crosstalk than in my first proto(board) But for sure sliding noise will not change (we talk about 40dB difference between TKD and ALPS !!!) I'm sure P&G will work fine too, but honestly I can't buy all possible mid/high-end fader to perform test. there is at least 4 or 5 candidate. Best Zam

All three 89MotioN board are done, I made them fitting my need, but in the mean time OEM where not in conflict with my hardware implementation. Small batch/kit/premounted system are of course possible, and I'm sure there is some interest here and at groupDIY for all those pple who dream about DIY true passive motorized fader. Usecase can be hudge, from console modification to automated advanced summing box with all those ppl intensively using API500 rack But, I have to see precisely how it work here as the system is opensource with some rules I don't look in details. Also I won't involve other pple money or trust in this system before I'm not 100% sure it work with reliability. It's not a cheap project, depending of fader choices and mechanical integration requirement it's a 3k to 4k project for 8 fader. As I say only one fader finished yet. I wait to fund a 8 fader pack, need about 2500 buck for this, main cost is TKD fader and front panel Hope I can do this in the next 3 month, then at least 3 or 6 month for real life crash test at the studio. It's a long term project, i'm on it since one and an half year now Best Zam

Hi Eric Welcome here, but your not really newbie in DIY forum ;) Nice to see you aroud this forum too. Midibox is used for the soft side with MB_NG version, fully programmable midi interface. Midibox hardware design also used for the core and line transmitter/receiver My part of work in this project is the analogue motor driver. Also the analogue/digital I/O board, inspired by midibox MBHP modules to keep the system compatible this 89InouT board is basically a combination and adaptation/improvement for my use case of: 1 AINSER, 1 AOUT_NG, 8 Din and 8 Dout. It interconnect at core with standard MBHP connector specification, even if I use micromatch due to restricted room for my design, pinout still 100% compatible. just one side of ribbon cable use micromatch connector. The motor driver is inspired from 90' highend console. It's an analogue PID controller, connected to two CV value with comparator one CV is the fader servo track (also send to the AD so the system can read/print position) other CV come from the DA who give the position that the system have already printed/stored This pcb also include an analogue touch detection (connected to a digital input) and an optocoupler (connected to a digital output) which in my use case active the original channel mute, with fully decoupling from the digital noisy world.

Ok here it is :) 1 fader pack with PID and LED pcb, also keeping the original fader PCB which interconnect passive part of the fader, audio and signaling PFL circuit everything fit in original studer cassette InOut pcb with 8 ch AD-DA and 64Din 64 Dout 19' rack with hi Q vero PSU +5 and +/-15, the core32 and the line transmiter And the beauty :) I'm proud of what I done, and really like to thanks Thorsten for the beautiful software and all other for help around this place. At this point everything working great, but it's not finished... I have to run it with full 8 fader pack to be sure it's a viable system, and I'm not able to fund this in a short range. Zam

I want to update but can't insert pict :(

:) To light two LED with aftertouch and MCU protocole Copy/past from my config, showing channel 6 led meter (for some hardware reason it's the only one fader loaded at this time) aftertouch use value 0 to 15 for ch 1, value 16 to 23 for ch two etc... ch 6 is value 80 to 95 ------------------------- # this one dim the LED 44 (yellow) with 15 step (value 95 never happen...)

you mean this for .NGR or .NGC ? Best Zam

Hi again Just thinking about new if_ * parameter for .NGC if_more= if_moreequal= Best Zam

Hello TK Tks ! I just do the update Look fine for the moment with my config. The ngc ram is a good thing, now I don't hesitate to use meta runsection to emulate button/led pattern toggle (MCU automation mode in my use case) So now the 1.34pre1 begin ?!? with 10bit CV map/table My project is really growing up, I will update soon in the correct forum section. Best Zam

Wait !!!! I just see little arrow at right hand button (from bottom side) are you sure this is not an indication for wire connection??? It may explain why there is no trace here and why button don't work ?!?

Hello I find something strange in your pic I hope it's a 4 layer PCB because I don't see any trace to any pad for the removed button ?!? If it's a 2 layer there is a manufacturing problem here If it's a 4 layer the broken pads will be a problem to connect again the inner traces :( As a global note and i don't want to balm you, but the whole solder joint job don't look so nice, you may have a temperature problem or bad solder/flux It can result some problem :( hope you find someone to help you ! Best Zam

Look like a nice function ! can we have a short example and how to write it? "event_button id=1 type=noteon chn=1 key=0x00 inverted=1" will send note on button depresed and note off button pressed, for a momentary on button contact type, is that ok ? Best Zam

Hello Samy Welcome to the board The SD card socket you link look like SMD pin at the back side, core 32 have footprint for bottom side TH soldering, it won't fit. Or maybe if you bend the pin? Check datasheet/footprint for both. Best Zam

Hi Thorsten tks for info, then I will put 5631 in the basket and try them. Best Zam

Hi Without proper socket my SD card is connected at J16 with ribbon and direct solder to SDhoder for miniSD card, but that' not the point :) Anyway I just find the info at J16 description for STM32 (miss that...) so I check again SD card page and ETH page. SD use RC1 and ETH use RC2 Now whole J16 connection make sense to me :) Best Zam

Hi My question is very simple, I read about MBHP_ETH but It's not clear to me if I can connect both SDcard and ETH at J16 ?!? I'm using STM32F4 core, and I want to try OSC for my system. I'm planing to do it in protoboard, but maybe there is some interest if I take the PCB (with kicad) route ? For info the controller seems available again in DIL package at reichelt. Best Zam

Hi TK Just a question about TLV5631 As the price is 1/3 of the 12bit version, I'm thinking of using it for my fader CV out data which work fine at 10bit and I don't see any reason to have better resolution (0,1mm travel is way enough). Ca I expect to run 5631 at full res 10bit and having the same precision than a 5630 downgraded at 10bit. Data sheet talk about full scale and non linearity error but I have no idea how this translate for real at DAC output. Best Zam

some news After one week fighting to recover my kicad project in the suddenly dead PC (exactly when I trace the last gerber pcb !!!! unbelievable ...), I finally was able to install stable Kicad to an OSX10.11. I just ordered the PCBs :) Best JS

solved! cool :)
