Topic: Help with midi programming in swift to send midi commands to pianoteq

Hi I have written a program that takes a midi file of say a Chopin waltz. The program makes sure the right notes (pitch) are played in the right order but I control when the notes start/stop and their volume and sustain pedal. Basically I cannot play a wrong note (pitch). This can either be played from a touch screen on an iphone or ipad or with a midi keyboard plugged into the iphone or ipad. So far the sound output has used different piano soundfonts. Clearly these are of terrible quality compared to Pianoteq. I have browsed the forum but not found what I am looking for.
I am a very amateur programmer and am struggling to know how to write the simplest code in Swift for a program running on my Mac to output a midi noteon, pitch, volume message to pianoteq running on the same Mac will pick up and play. If someone could give me a few snippets of code to start me off I would be immensely grateful. I have browsed the forum but not found what I am looking for. Many thanks.

Re: Help with midi programming in swift to send midi commands to pianoteq

I only program on Windows and Linux, so I don't have any experience with recent Mac programming, but I do know that OSX has an IAC Bus for inter-application MIDI communication.  You'll need to turn it on in the settings for your Mac.  Once it's on, you can use something like the MIKMIDI library (which is well-maintained and well-documented) to pass the signal to the IAC bus, and--as long as the IAC and all other MIDI ports are open in Pianoteq settings, you should be basically where you need to be.

Thanks very much. That worked very straight forwardly. I have been using PGMidi but will also look at MIKMIDI
Great when a simple suggestion solves something you have wrestled with unsuccessfully!
