any ideas on how to add more MIDI DIN ins/out to Axoloti?
I can see there is an additional RX/TX not the back connections... so presumably this could add one more in and out? (need a +5v out for din) ... but Id really want more.
presumably for more, we could turn to the digital I/O pins, and link to some kind of UART to create a serial link?
is this viable? or very complex?
does anyone know of any example circuits, perhaps produced for another board (ardiuno etc)
ideal scenario, would perhaps be putting 4 - 8 (!) IO din on a separate expansion board with the dins + any other required electronics. (uarts), circuits I've seen so far, seem within my (limited) build abilities, just Ive no idea on how to design such a thing
what sparked this idea was a review on sonicstate of the Sipario. see here, which is basically an intelligent midi router
... and I thought, thats cool, but I could do that easily with Axoloti... and actually better in some ways due to having both usb midi device and host. BUT as pointed out, lack of midi din is an issue...
(the Sipario has 2x i/o, but really something like 4x io would be ideal for an intelligent midi mangler)
of course, what I like about axoloti, is it can go much further, not just mapping midi, but also sequencing, and also 'midi effects'... downside (aside from the midi din i/o) is UI, but Ive ideas for that
note: yeah, I could to this with multiple axoloti boards, but seems a little excessive for this use.
funny, Ive a few axoloti boards, but just keep finding so many uses for them... and nice to be able to have them have 'dedicated' (but programmable) functions littered around my studio.
anyway, any thoughts on more midi din i/o?
