8x8 matrix for Modular synth

[xarolium]

Dear Midiboxer

I need your help to realise my project because i've a lot of question

Project description:

I would like to realise a 8x8  matrix for my modular synth with 8IN and 8 out, a Matrix led and 16 switches, exactly the Midibox SID matrix but where i can connect what i want (vco out, adsr in, vcf out...)

I would like to save the patch in a bankstik

I add 4 switch to save, load, choose my patch

I need 64 relay and a midibox application to control them

Configuration:

1 core, the brain

3 DIN for the 16 switches to control the matrix and the 4 switches MENU

1 DOUT for the matrix LED

8 DOUT to control the 64 relay

1 Bankstik to save each configuration

1 LCD

Question:

Which midibox application will be the best to do it?

Which relay do you think i need? Can i use CMOS4066 instead of relay?

Can i save some configuration with MIDIBOX 128?

thank you for your futur answer

i would use button duoled matrix app if i were you and customize the app writing your own app. this allow you to have 64x2 Digital outputs and 64 Digital input.

the 64 first dout would allow you to use led to see which frame is "ON" and the second 64 DOUT would be sent to relays.

you will only use 2 74HC165 and 4 74HC595, one core and one bankstick. very cheap. the only problem you will have is to write the application in order to store the patches.

I would like some help to do my program

My line of switch number 1 to 8

My column of switch number 9 to 16

The LED number 1 to 64

Example:

If Sw1=1 and Sw9=1 or (Recieve Midi Message Note ON C1 canal 1)

Set Led1=1 and Dout SR1 Pin1=1

If Sw1=1 and Sw10=1 or (Recieve Midi Message Note ON C#1 canal 1)

Set Led2=1 and Dout SR1 Pin2=1

........

If Sw1=0 and Sw9=0 or (Recieve Midi Message Note off C1 canal 1)

Set Led1=0 and Dout SR1 Pin1=0

If Sw1=0 and Sw10=0 or (Recieve Midi Message Note off C#1 canal 1)

Set Led2=0 and Dout SR1 Pin2=0

.......

I would like to know how to translate this in my program
