Does the Axoloti have some sort of auxiliary output and input?
I have some pedals and know how to make some simple analogue filters. I think it'd be fun to incorporate them into my project (might sound interesting to)
Is the Axoloti capable of outputting a signal to an external filter, then receiving that signal back into a patch, then finally outputting to the audio output/headphone jack?
no and yes.
there are no dedicated pins to do this.
you can route audio out of left side of stereo jack, input back on left side of stereo input and output on the right stereo side of jack. it will be mono, but should work.
no, there is no additional io,
the adc/dac within Axoloti only supports for 2 channel in and 2 channels out.
(the headphone output is not separated from the main output)
so you could do this if you used a mono on the return, and a mono main output.
to go beyond this, would require you to add an additional external adc/dac, and then coding support for this into the firmware.
in the future its hope there will be the possibility of connecting multiple Axoloti boards via a digital link which would include multiple audio channels.
this would allow for the possibility of using another Axoloti for the analog IO, e.g. for external effects such as filters. albeit, this would introduce a little latency.
note: there is no release date planned for this yet
e.g.
axo 1 -> (digital) -> axo 2 -> (dac) -> filter
<- (digital) -> axo 2 <- (adc) <- filter
-> (dac) main outputAhhh bummer about the pins, but ehh still pretty amazed by the board and software in general.
As for the stereo input: will that input signal have to run through the entire patch, or can I choose which point it enters the patch?
...also what if i run out through the headphones, then through my filter, then back in through the stereo input then back out through the quarter inch output?
you can choose where you want to connect the audio/in
as i said... the headphone output is not separated from the main output.
its the same signal as the main output, so this will not work.
Ohhhhhh! I understand now. I had trouble visualizing things in my head for a second...I also understand the mono comments from earlier a bit better after pondering it for a bit.
Thanks for the answers!
I use what are known as insert leads to access the audio channels separately, they have a stereo 1/4 Jack on one end and 2 mono jacks on the other. I've got 2, one each for input and output.and have them plugged into the back of a patch bay so i can route signals through various outboard effects easily.
If you run a mono signal you can run a loop like thetechnobear described.
