TouchOSC 1.7 update now has line6 and coremidi support this means no need for puredata or oscillator. I will be updating all TouchOSC templates as soon as possible making this the default way of connecting TouchOSC to your computer. CoreMidi is supported natively on OSX and on windows you just need to run a small app you can find here rtpMIDI (read more below) For now here is how to set up CoreMIDI on Windows and Mac. Windows XP/Vista/7 users, configure MIDI networking on your PC: - download the rtpMIDI software (free) from Tobias Erichsen and install it. Follow the setup instructions on Tobias’s website or the summary given in the below steps.- launch rtpMIDI. - in the “My Session” top-left area, click the “+” button to add a new session (or reuse an existing one if any). You can change the name of the created session by editing the “Local Name” field on the right of the window. This name will appear in your DAW as a MIDI port. - in the bottom-left “Who may connect to me” section, select “Anyone” or “Only computers in my Directory”. - from TouchOSC on the iPad, touch CoreMIDI: you should enable it if it is not. - on the PC, select the line identifying your iPad in the rtpMIDI window and click the “Connect” button: your iPad identification now appears in the “Participants” section (top-right).
