Axoloti for busking

#1

Being born as a keyboard player, finding ways to play an instrument that I could carry has always been a solution to too many back problems.
Having lost myself lately in synths of all kind (cheap, I'm unemployed) I found axoloti a great way to have a never ending evolving setup, in a small, light package.
I'm ending my summer on the road without a fixed house, and had fun on a few stops with the axoloti and a few patches.
The axoloti is running with a SD card with my patch on startup, powered by a small 5v USB power pack. (The pack can last for hours and hours it seems). I'm feeding in a midi keyboard by USB, giving me 8 knobs for #cc control.

I made a few videos with a simple patch based on the 2 Osc fm feedback patch with a few stomp effects and some pitch and a filter.

I'm really looking forward to making myself something portable but with a load of knobs smile

cool jam!!
I had not thought about it, going portable. That's great!!
what sort of powerpack are you using?

#3

Awesome!
Great to see Axoloti is not just about building and tweaking patches, but ultimately is about playing.

I'm using a simple USB portable power modulo by IDAPT (a kickstarter project)
It's a 2100 mAh 5v 1.2A battery, nothing fancy, I've used it more than 5 hours and it still says it's fully charged (3 LEDs out of 3). My USB keyboard is powered by AA batteries, so is my portable amp (and in this case, my zoom h4 too). I can more or less do 7 hours non stop before changing batteries

Here are a few more videos with the same setup, and some day soon, I'll put a jam with a Roland modular setup (old and new) against me and the axoloti

Great jam! Very expressive patch!

USB "power bank"-style batteries are indeed a good choice to power Axoloti.
If your USB keyboard works on USB power - and most do, you do not need batteries in there.

#7

Ive wondered about these, Can you just plug everything into the usb battery and the datalines just talk to each other? Or do you need a hub?

#8

No, datalines in USB batteries are not connected.
The USB host port on Axoloti will provide power to a USB device connected to it, if you provide sufficient power to its micro-USB device connector or DC barrel connector.
USB hubs on the host port are not supported (and won't work).
A USB hub between a USB battery and Axoloti Core would only serve as a power splitter, but will not enable any communication between Axoloti Core and other devices connected to the hub.

@herrprof: Yes that works. I use a similar setup here

Usb Bat -> Micro Usb(Axo)
USB A(Axo) -> Arturia Mini Lab (The Keyboard)

But you have to keep in mind, that you should not draw more than 1.0 ampere over the micro USB. The USB A can only draw 500 mA. So your keyboard should not draw more than 500 mA (Most moder keyboard will work in this scenario.)

@johannes was faster smile

Ah that makes sense! Two desperate ports are handy in this situation!
