Welcome to the Motivation-Radio-WiFiOSC wiki!

The WiFiOSC app is a very simple example of what can be done with OSC (Open Sound Control) messages. OSC is very flexible. One interesting application of OSC is for configuring a Eurorack module. e.g. if you created an LFO sketch for Motivation Radio you could use OSC messages to set the frequency and amplitude of the LFO. You could then create a nice UI in TouchOSC to control the LFO with your iPad or phone.

TouchOSC is a really nice app for creating custom UIs to control your rack with an iPad or phone. There are other similar apps but from what I've read TouchOSC has the best feature set, it is quite stable and its not that expensive. There is a bit of a learning curve for creating UIs, syncing them to your device and getting everything configured. The end result though is a very nice touch interface that is highly customizable - and you don't have to write any iOS code! TouchOSC also supports MIDI so it will work very nicely with the BLEMIDI app for Motivation Radio. MIDI is much more constrained in scope than OSC. Bluetooth is generally easier to set up than WiFi but there is no OSC over Bluetooth profile that I'm aware of - Bluetooth ease of setup with OSC flexibility would be really sweet!

For the VCV Rack fans (VCV sent me down the modular rathole!) there is a cool plugin by Trowasoft called cvOSCcv that can send and receive control voltage OSC messages. I had it working with Motivation Radio but when I tried it a few months ago (late 2018) cvOSCcv was quite tricky to configure and get working. If they get this plugin more stable it has the potential along with Motivation Radio to be a wireless bridge between virtual and real Eurorack synths which is super cool.

Wireless Latency - I've experienced some pretty bad latency on my WiFi network (which is shared with other devices in my home) - at times hundreds of milliseconds. If you need something done with minimum latency a shared WiFi network is probably not a good choice - use a dedicated WiFi router. From what I've read OSC is really intended to be used with wired networks which have much more predicable latency and jitter.
