Lu Taska Posted July 12, 2010 Report Share Posted July 12, 2010 So I've spent some time doing some reading, and I beleive that in the coming weeks I'll be ready to start my project. The plan is to have a 16channel motor fader board plus one master fader. By my understanding and calculations I will need the following: 3x PIC18F452 cores - 8 faders max on each core, therefore I need three. Right? 4x 2x40 character LCDs 6x DOUTX4s 3x Motorfaders (right? 8+8+1?) Here is where I am getting confused. I've crudely worked out that I need 6 DINx4s with the following logic: Since I only need a single master section, a 2 LC design doesn't need twice the buttons that 2 single LCs would have. And, as aach extra channel contributes four switches, an extra eight channels will contribute 32 switches. Therefore i should only need an extra two DINx4s right? Also, do these three cores connect individually or are they chained somehow? And on extension, how many LTCs will i need? One or three? Thanks for your help. I'll keep looking over Axel's posts while I wait for replies :P. Quote Link to comment Share on other sites More sharing options...
Screaming_Rabbit Posted July 12, 2010 Report Share Posted July 12, 2010 Hi Lu Taska Yes, for your Master Fader, you need an additional core - Do you really need a Master? - Think about it. Regarding the MF-Boards I would suggest, that you take 2 and the single Master Fader you build just partially on a stripboard. Regarding the DIN/DOUT boards you see it correct but I don't feel for counting it through. Regarding the connection of the units, it depends on your host soft. In Sequoia I would connect the master-unit as an independent unit on its own midi port. If you want to connect it together with an 8-fader unit onto one port and handle it as the "master"-controller, you probably have to make use of MidiBox-Link. About how many LTCs - Go for one GM5 Greets, Roger Quote Link to comment Share on other sites More sharing options...

About how many LTCs - Go for one GM5 Greets, Roger I am also busy with a project like this & will need 3 cores for the faders. If I have this correct, to connect all cores with my computer (I use ProTools on a MAC), I will need for each core a seperate MIDI port. That means 6 cables, 3xIN and 3xOUT. Is that correct? thx Edited July 14, 2010 by SNG Quote Link to comment Share on other sites More sharing options...
Screaming_Rabbit Posted July 14, 2010 Report Share Posted July 14, 2010 That means 6 cables, 2xIN and 2xOUT. ... what now? :rolleyes: The answer you see in my previous post above: "Regarding the connection of the units, it depends on your host soft.

Lu Taska Posted July 14, 2010 Author Report Share Posted July 14, 2010 Which GM5 will I need? The 5/5 or the 1/1? Quote Link to comment Share on other sites More sharing options...
SNG Posted July 14, 2010 Report Share Posted July 14, 2010 Which GM5 will I need? The 5/5 or the 1/1? the 5/5 as you use 3 cores and need at least 3 MIDI connections... good to have 2 reserve for later expansions.... or you can use the 4th port for the master fader as suggested by Roger :) I will not use a separate master fader as each fader on my master panel can function as the master fader... we all have our own preferences :)))) I have just calculated that I need for all my VU LED panels an separate core and 4xDOUT4.... is it possible to use a link or LTC to guide the signal through an another core...???

Screaming_Rabbit Posted July 14, 2010 Report Share Posted July 14, 2010 .... is it possible to use a link or LTC to guide the signal through an another core...??? Yes, use MidiBox_Link. Though I can't remember anybody posting who used it on MidiBox LC - Give it a try. Greets, Roger Quote Link to comment Share on other sites More sharing options...
nILS Posted July 14, 2010 Report Share Posted July 14, 2010 Which GM5 will I need? The 5/5 or the 1/1? The gm5 (which is the fun little IC) is always a 5/5. I think you're referring to the PCB: single IO PCB with the possibility to extend (which is what TK sells) or the gm5x5x5 (which is what I sell).

Is it supplied with the GM5 chip? Quote Link to comment Share on other sites More sharing options...
