I have K machine but still barely have any idea what I'm doing!
Lots of great tips on here, thank you so much!
I'm at family reunion so can only tinker when the lights are out atm. I'll get back here and report on progress when I've made some.
Talk soon!
You can also send MIDI to your iPad using Network MIDI over WiFi. Network MIDI has been built into Mac OS and iOS from the start.
Someone pointed me to this project to convert a Raspberry Pi to a USB MIDI Host/HUB (that also has bluetooth capability):
https://neuma.studio/rpi-as-midi-host.html
I am a total Noob. I am wondering what sort of cable I would need to connect the iPad (via camera connection kit to the Raspberry pi.
@espiegel123 I have no idea, and not to drag you off into another direction, but re-reading this thread jogged my memory.
Could you use midi over Ethernet for the pi?
@espiegel123 back on track I think loopop (YouTube) did a whole video about midi connections and hubs.
I’ll try to find it. Found it...
7:20 for RaspberryPi
I know there is a way to use some of the serial GPIO pins to get 5 pin MIDI connections. Otherwise, I’d probably connect two USB to MIDI interfaces and connect them that way.
What kind of MIDI to visual software are you using with your Pi?
Not using a MIDI to visual software. I would be using the setup to use MIDI Designer Pro to send MIDI to a Boss Katana amp using the Raspberry Pi as USB MIDI Host. The Katana has some sysex quirks that require such a setup.
So, I would prefer to connect from the iPad to the Raspberry Pi via USB if it is possible not using 5pin MIDI connector. I have a CCK and would prefer not to get a MIDI interface in addition to using the Rpi.
Excellent video. I am still unclear as to what would be needed to connect an iPad ( as a MIDI device) to a Raspberry API.
Oh, I just realized this is an old thread. I meant the OP says something about visuals.
The iPad isn’t a class compliant MIDI device, so that is probably not going to work out for you. You need something like IDAM but for arm based Linux. I’ve never tried the iConnectAudio on the Pi, I wonder if that would or wouldn’t work. I suppose you can look around there might be a way, but you’ll probably spend a lot of time and may never find a resolution.
If that article you posted above is true and works you can just send bluetooth MIDI to it and that should work, but I wonder how bad the latency will be to the Pi and then to your amp.
The latency wouldn't be a problem.Audio isn't going to/from the amp. It is to use the iPad as an editor for the amp's controls and to essentially have more presets than the amp natively stores.
It seems like Bluetooth is going to be the way to go.
@espiegel123
So, a raspberrypi can function as a midi host, and you want the iPad to be a midi device? The kind the usually ends with the square usb (not rectangular)?

Could this work
iPad midi designer pro —> midimttr —> rasppi (wireless) —> cable rect to square —> katana amp
I just heard from the guy who posted the RPi project. The answer as you suggest is to connect the iPad via Bluetooth rather than over a wired connection.
Bluetooth midi ,now works on Linux , but sometimes the port goes off . Also never tried sysex via Bluetooth (I don’t know if it’s supported )
Another thing to note is raspberry does not act as Bluetooth peripheral (not detectable from iPad) so you have to advertise Bluetooth service from the iPad and then write a script from raspberry to automatically connect and forward the messages to midiout (to katana)
If you can’t connect via Bluetooth I could write a wrapper in PureData to go via WiFi .
In iOS there is MobMuPlat and PdParty
But there is another problem, in the past MobMuPlat app was freezing after receiving some sysex messages and haven’t tested PdParty at all.
Of course that means that the raspberry must act as a hotspot (or use a cellular device)
Maybe the Bomebox could be useful for someone?
The RPi project I linked to above addresses all those issues. As for sysex over Bluetooth , the person that created the MIDI Designer template for controlling the Katana is using Bluetooth . In fact his solution is using a Yamaha Bluetooth connector on the katana.
There is a potential advantage to the RPi in this case in that it is apparently more compatible with some Roland/BOSS midi over USB quirks than the Yamaha.
Maybe you missed my link to the project I was talking about:
https://neuma.studio/rpi-as-midi-host.html
Features: USB MIDI (which is what I prefer for this project), automatic MIDI Bluetooth connections
I would be using it to make use of this MDP template for controlling a Katana:

Nice. Thanks for reposting your links.
