iOS app : midi controller pro w/ Axoloti

#1

Hi,
it seems that there is not a topic for ios apps?

i found an app called "midi controller pro" where i can build my own controller which should be a perfect low cost diy solution for me. I started building a controller and the keyboard works fine, but i try to add sliders for cc and it doesn't seem to work. Anybody got an idea what i am doing wrong? What i see is that the slider produces midi messages with a few variables, so there could be a mistake, or something with the cc object. Both things are new to me, so any help appreciated!

Ive moved to a new topic

sorry, Im not familiar with midi controller pro...
but I did test axoloti with other iOS apps and it seemed to be working ok. (ive not tested recently, but will give it a another go :slight_smile: )

midi CC messages report 2 values, the CC number and the value.

there is in axoloti in midi monitor object, that reports all midi messages, its low level, but the best way to see if we are getting what we expect.

have you tested this application against a PC or Mac, where you can use a midi monitor, see if its configuration of the app, or an issue specific to axoloti

btw: is this axoloti on 1.0.11 (if not please upgrade to this) , also what iOS device is it...

please note: dont plug any device into the USB host port on axoloti when using it connected to iOS devices. the apple device only just about has enough power to power axoloti, its likely that many midi devices attached to the axoloti at the same time could require too much power from the iPad/iPhone.

Thanks for moving the post. I think midi controller pro probably is a nice option for a diy controller!

My axoloti is updated and I am using an iPad mini 1.

Actually I have no idea how to send the midi data of the iPad to my windows laptop...

I cant say anything about midi controller pro, as Ive not used it.
I personally use Lemur, and have for quite a while now, but its quite similar I guess.

anyway, tested with Lemur, sending CCs from my old iPhone4s to Axoloti, and it worked fine.
so I'm guessing its probably to do with how you setup midi controller pro

sorry, I don't use windows, so not sure how this is done there... I'm sure there must be details on this somewhere as many people use iPads etc to control Ableton Live.

I have set up a windows connection, and the cc message looks like this:

0x003500B2

Can anybody tell me if this is ok for a cc 2 message?

This is a keyboard message btw:

0x007F3990

your data is 'backwards'
CC should be 0xB20035, this would be CC 0 on midi channel 3, value 35
note should be 0x90397f, which would be note on, midi channel 1, note 37 velocity 127.
