What is the MIDI Opto-Coupler you use? Seems to be a smd one.

You can try with BC559 which is very close to the 2N3906 A normal polarized 10uF will work too ;) Great testing environment!!, share your result please because lot of people ask me to create a Quad TIA synth and the associated Control Surface. My plan is to a add a SSM2045 or NJM2069 to each TIA, to enhance its amplitude precision, add a LPF and rewrite TIA interfacing under MIOS32 on STM... Next... If some people want to help me working on it they are welcome, it's just a question of time, no enough :(

For the assembly: "the um6526p1 you shipped, is the "Pal Tia-mono?" so the 3rd figure on the pcb is the one i have to jumper. " Yes the TIA model I provide is a TIA PAL version There's 8 auxiliary lines on DB25 connector, I added non used PIC Pins for other purpose, first ideas were to add original Atari joystick or pad, Interconnect Boxes by CAN or add a small CS AUX4-7 are respectively RA5, RE0-2 and this jumpers permit to switch AUX0-3 between RA0-3 and RB0-3. You can access, INT, CAN, AD and others pin function of the PIC. Pin 1 for both are at Top/Left. It's Only Patches Datas which are in the external EEPROM Array. All System like MIDI Ch config are stored in the Internal ROM of the PIC. The external EEPROM are not a condition for the box to work. I just suggest a 9V supply because it's enough and avoid heat from regulator, the regulator heat depends on the difference between its input and output.Greater is the Voltage input Hotter it will be. I don't suggest you to supply the board from 5V I/O, you will get some digital noise on the audio output, this 5V I/O is much more to provide 5V supply for the AUX. If you want to interconnect boards in parallel with only one reg on first board, Reg is a LM7805CT and can provide 1A(enough for 4), better to do it here: The other way is to populate the 4 regulators and provide 9-12v from the same external supply to all boards. I refreshed the schematics: Hope I answered to your questions. Antichambre

There's 8 auxiliary lines, for other purposes like original Atari joystick or pad for example. AUX4-7 are respectively RA5, RE0-2 and this jumpers permit to switch AUX0-3 between RA0-3 and RB0-3. You can access, INT, CAN, AD and others pin function of the PIC. You can access free pin and add something if you want. That's all ;) ...It's late here. I will do a complete answer tomorrow morning.

Yes of course! ;) ... I though about this too. Yes, hidden parameters should be hidden, have an unique scripting name, an automation name, parameter visibility must be "Automated and Store". This must not be a CC but only a live parameter. All change will be recorded and view as parameter in the timeline or clip. The track only record Notes and Automation, No CC, the plugin can filter it, CC are send and receive to the Box thru Standalone Manager. On receive from CC... Manager set is CS and send data to automation in Live. On Live Automation Change... plugin send data to manager... Manager send it to box On Manager CS change.. it send it to Live automation and to box. I think Program change on Live should be an Automation parameter too, same as CC except that All automation parameters receive data from Manager on its Sysex reception. It should work, obviously Latency needs to be tested and on some different OS and computer Not that much ;) There's RPN and NRPN for CC and I think Automation Parameters are unlimited.

Yes Midi I/O can be shared on a Mac.

Thru UDP Localhost, this is a good idea, I didn't think about it. Then you suggest to get the standalone and the plugin working together? By this way we don't need the CS under Max4Live just a linker plugin in UDP which communicate with the standAlone Manager. I will work on this idea, but first I have to finish prepare and send your toy. I can share Patchs and source files because it's a lot of Javascript inside.

Yes with this app on your ipad. But this old one seems no more available on the App Store :( Now there's Mira from Cycling'74 but it's 11E the app :/ I Haven't got an android to try it, it seems the same kind of app exists now on android, here, then it's possible to add it. But I don't know if we can customize buttons and sliders...

I was looking for the Max4Live version of the manager. I've got it ;) It can work it's just a degraded version of the full one. But it is limited to control, You can change Preset via Program change of the track in live, but the plugin can not reflect the exact state of the machine. Preset are transmit via sysex and Max is hosted in Live and this last doesn't manage the Sysex message. The TIA has a CC dump function but the host track has to be in input mode to receive it. Then complicated. The standalone version receive and send preset thru Sysex. No problem. Maybe I can add a Save function in the TIA thru CC. And the box will save its state in the last Preset loaded by program change. I will try and share. An other way is to create a fake plugin and to put it in an other track in Input/Mute, A kind of Ghost track which inputs from the box. I can add a data link between the two plugins. A normal track with the manager in it for control which ask for a CC dump on each Program change and a ghost track with the 'fake' plugin which will receive the dump and set parameters of the manager without loop. I will try too.

Maybe my english is not enough 'subtile' I'm agree with you, my version is a full one with my own license, same thing for others like Autocad, one of the more expensive, AND I'm not a big society I'm freelance then believe me I know the price! And what they win... Then ok for this first thing, now. For Kicad, we can talk about and put Pros and Cons on a table, it's just my opinion after tried it, and it's not the purpose of the topic, you're not obliged to be agree with me, I understand that you can love it, I "get it". Like me you can just respect my opinion. I changed my post, for next time in MP please. @Lisa, I've got this licenced tool if you want to follow the rules. BR

If you're sure of your schematic and mechanical constraints, like switches, encs, leds and holes positions, it just remains Design rules. You can share it in eagle? And tell where you want to manufacture it... Hope during too much time to see another status than "Sold out" for this item and others, that's a shame... I think I will take part of this bulk too. It should be fine as a first test for my OLRE16.
-
Hi Lisa, I don't know PCB-RND , like you I hate Kicad ... I use Eagle, in it, there 's some electrical check named ERC which check Layout from diagram. This ERC can be fine but first thing to check is your schematic ;) When that's done and clear, you need to do a DRC which will check production rules match, depends on manufacturer you use to be sure no error will be produced during this last step.

You can collect the chorus board too, which is a separate one, put it in box with a supply and some I/O connectors as an external effect.

Maybe the interresting parts are not dead! I found it on ebay: http://www.ebay.fr/itm/162501568610I I negotiated price for 10 thru best offer function. Yes I will try it but after summer I think, because I have a lot things to finish before beginning an other...

Hi Datacore, It's Neutrik SerieD USB NAUSB-X BR -
Yes, but the phasing is from the Korg, I love this old machine from the 80s. About this i've got something to tell.... There's some mods for the Ex-800(desktop version of the Poly-800) on the internet , the hawk for example, my EX-800 is not modded, want to keep it like it is but... As usual I did not resist to open it and watch how the beast is made with and of course browse the schematic. I discover something very interesting, the OSC part is a digital one, Korg was used it for this polyphonic Synth but originally it was an Arcade Game Sound Generator.... Now You guess where I'm coming to ;) This chip is an MSM5232 from OKI, here the datasheet. It's an 8 voices generator with 8 bit data bus and easily controllable with modern DAC for is analog inputs like EG. A good friend for a CORE :) Another good part inside is the VCF chip, it's an NJM2069, pretty same as a SSM2044, it's LPF 2/4 poles but with 3 VCA included and a dual ramp supply in +/-5V not +/-15V, I already order some to add to the TIA which hasn't got any filter. I already search and found some provider for the MS5232. And I will order some very soon. Tell me if you're interested ;) Best regards

Thank you, I made this very quickly, i think I will come back on this track later. It deserves to be on a timeline.. That's the point!.. Of all our work, it's not just a geek thing! isn't it? You will test it by yourself soon, I'm in a hurry to listen to what everybody will do with it Best

A demo track for the TIA. Recorded on the fly, live act. Bass : Korg EX-800 Drum : Elektron MachineDrum Everything Else : Midibox-TIA BR Antichambre
-
Last track made with it. You cannot do that with the synthcart or other project based on the TIA Listen to the harmonics ! ;)
-
Samples from SynthCart I thing. You will discover something drastically more musical, soon ;)
-
Ok seems this issue is not a problem for everyone :) Yesterday I received all cables. I made one breakout cable for example, this is what you will receive, it will remain to you to cover the DB25 with housing and solder the DC connector. Clean and cheap. Best regards

Yes it is minor, but not perfect :/
