A bit of clarification – I’m trying to use osc rather than midi for now. I am using iannixtomidi within max for live to convert osc to midi. I can see that iannixtomidi is set to receive on port 2001 – using ‘udpreceive’. I can see that iannixtomidi can send to iannix (on port 1234), but for some reason getting iannix to send on port 2001 creates a conflict. Must be a windows thing.
