I love my Axoloti! I too have the MTM addition and he did a splendid job with it.
Wow, i just spent one hour or so with it.
First of all, installation is very easy and takes 5 minutes.
Making a sound after 1 minute patching.
All the examples and tutorials work, nothing is missing.
I am so impressed so far.
Love it. Had mine since December.
My only complaint about the MTM controller is that it doesn’t have any noise filtering for the controls. I usually end up putting one-pole filters or slew on each pot digitally to remove some of it.

By the way, just saw this
How does this compare to axoloti or aleph or any other product you’d know in that category. It feels like something at the junction of both but doesn’t look as simple and open as the first, and as slick and beautiful as the second.
Zynthian looks very interesting, especially as I already have a PI2 and HIBerry DAC+
it appears to be based on a PI2 (or 3), and appears to glue a few existing open source pieces together, which is cool, as this is tricky in itself. looks like a a nice PI solution.
its seem to be aimed as a more ‘out of the box’ instrument, i.e. providing some ‘standard’ linux synths/samplers rather than patching synths.
(axoloti is a virtual modular synth environment, so you make your own synths, midi router, sequencer or whatever)
its a different approach to axoloti which runs a real time os (chibios) which is very light, and has very low latency, which you cannot achieve with linux systems (*) . the other issue with PI systems are they are relatively slow to start up , and the SD cards do fail.
on the flip side a PI has a lot more cpu power, and is obviously a general purpose OS…
(there is a more detailed comparison on the axoloti site)
theres another solution that is somewhere between the axoloti and PI :
Bela (http://bela.io) , I’ve got a couple of these on there way to me too… Bela is a a cape for a Beagle Bone Black, but this runs a hard real time linux kernel called Xenomai, and the cape provides audio processing in that real time context.
Bela, I think, is more aimed at ‘instrument makers’ but does interface with PD via Heavy or C++.
Bela’s site also has a good comparison of alternatives, including contrasting axoloti.
Its great to see a few different alternatives coming along, as these devices are great little portable musical devices… Im getting quite a collection now
This looks cool! I couldn’t find any mention of post-kickstarter plans… do you know if they plan to make the kit generally available after they’ve mailed them out to supporters?
I don’t know but I just noticed they have a new forum. Looks like they’re shipping to backers sometime this week. Should be interesting!
yeah, its perhaps worth pointing out with bela, you do have to be careful what code gets executed if you want to keep the kernel in realtime mode… you can’t just execute arbitrary code, and expect real time to continue.
e.g. in the other thread, there was talk of a monome, but using usb lib, will drop it out.
Im going to be playing a bit with this, when my Bela arrives … and seeing how this can be avoided. for use with my Soundplane.
That’s great. I’ll be eager to follow along to learn more about real-time Linux for audio. To be an instrument, the bela needs some kind of input, in any event!
woah, the axoloti also has a script object with a nice little editor that even auto closes brackets
also very impressed with the thing so far!
built my AxoControl from MTM today, first soldering project, and worked first time
its whetted my appetite creating some DIY instruments based around Axoloti and Bela, going to be a lot of fun.
The AxoControl is nice, really compact thing, to have 6 knobs, a joystick and 4 buttons… think it will allow Axoloti to be an interesting fx device… or even a simple midi controller.
only one thing I need to resolve, there are just not enough hours in the day to explore these things… guess I can’t blame MTM or Axoloti for that.
I love it. I did this
(I don’t know if embeds work with instagram, anyway this is the link https://www.instagram.com/p/BPAswgqBcIz/ )
its a nice idea, but the latency is i suspect not going to be good on a rPI, thats why Johannes chose an RTOS.
I do have to put my hand up here, and admit Ive had axoloti running on another platform (within the main axoloti code base) , and Ive been in discussions with Johannes about if we release it or not.
I approach Johannes because I was in two minds, he made the source code open source , so he derives no money from the (considerable) continued development he puts into it… he only makes ( a bit) of money from the hardware, so if people buy the other platform (or PI) instead, he makes no money, is this the best way forward for the community?
Its a tricky one, which is why I gave this decision back to Johannes.
(I also think, strongly, that sinneb should not be releasing this separately, but working with Johannes… dividing the community into axoloti users and pi users will not benefit anyone)
anyway to finish a bit more lighthearted, I’ll chuck this here… (a bit of irony, given the above ;))
Yeah, I hesitated to post this, intuiting what you say about how Johannes derives some income from all his hard work.
Not intending to encourage anybody to pursue this.
On a meta level, it’s interesting to see how it’s getting easier to run software modulars on inexpensive hardware, and I’d really like to see more of these things sprouting 1/8" jacks with some unipolar <-> bipolar voltage conversion, for integration with eurorack.
oh, not at all … this is the nature of open source, its open
I hope the developer contacts Johannes… Johannes is really open to such things, there really is no need for this to be a separate project, there is a much better/easier way to do this, that will benefit the combined community of axoloti and pi users.
@TheTechnobear fwiw, this discussion pushed me firmly over the edge to finally start saving for an Axoloti. looked at compiling this onto my Pi and ¯_(ツ)_/¯ would rather have the dedicated I/O and hardware that Johannes has worked to provide
Hi sinneb here, porter of Axoloti to the rpi zero. Thx for the mention, and thanks for the insights. I will contact Johannes today to talk about the Axoloti rpi zero port. The port is pure curiosity, not intended to harm income from the sales of Axoloti boards - it is intended as a totally different application of a great DSP engine and platform as a whole. Will talk it through with Johannes!
