MidiPipe FAQ

jrathkopf: the MidiPipe Microtuner is for people that don't own a device that supports micro tuning; MidiPipe makes micro tuning possible by using pitch bend messages and channel routing; after a scale is selected MidiPipe calculates the necessary pitch bend messages to tune the 12 possible notes of the octave; then it sends these 12 pitch bend messages to channel 1 to 12 and routes incoming note on/off messages to these channels (C to 1, C# to 2, D to 3 ...). This means that you need to create a Reason setup that has 12 identical synthesizers. Everyone has to listen to its "own" MIDI channel.
If you have trouble, please let me know.

Regards, Nico

I'm trying to get MidiPipe working between Logic 6.3 and a Show Control app called SAMSC in OSX. I can't get it to work and I'm assuming SAMSC won't let me assign a virtual I/O. Any suggestions?

Thanks

Did you create a virtual Out Port in MIDIPipe first?

[oh, and make sure you create a no-thru setup for the MIDIPipe virtual Out Port, in Logic first, otherwise you can quite easily create a MIDI loop, and have Logic freeze on you. To do this, cable the port on the Physical Input object to a null object [a monitor , or something, which is not cabled out to anything else] The virtual port will be the one following your existing In ports. [e.g. if you have 8 hardware In ports, the virtual port will be #9]

Excellent news.

Must try it out.

Do you have any example scripts ?

nicowald · Post by **nicowald** » 22 Jan 2004, 11:30

oink,

the "AppleScript Trigger" tool comes with a default script, which should give you a start on how to use the new feature. Here is an example on how to put a new message into the pipe:

on runme(message)
set outmessage to {144,60,64}
return outmessage
end runme

AppleScript documentation can be found here:
http://developer.apple.com/documentatio ... index.html

another example:

on runme(message)
if (item 1 of message = 148) and (item 2 of message = 0) then
tell application "Finder"
say "Note on key 0 channel 1"
end tell
end if
end runme

Happy MidiPipeing!

This is a great tool -- wonderful for trying out performance-related things with VSTi plugs.

A friend of mine has a direct USB-based controller/kb that he's trying to use with MTron. Of course, he needs something like MIDIPipe to translate the pitch bend wheel to MTron's controller #95. This works great with my MIDI keyboard into a MIDI<->USB interface, but it's not working for him. I have no easy way to troubleshoot this until I can get over to his house. Is there a way to configure MIDIPipe to handle his USB keyboard, or is he just missing something on the setup?

Hi Greg,

MidiPipe can use all MIDI devices that CoreMidi knows of. Please take a look into the "AudioMIDISetup" application to see these devices. If the USB-based controller/kb doesn't show up there, the reason could be that this device needs a driver. I own a Evolution MK-249C which is one of these devices that needs a driver.
I hope this helps.

Regards, Nico

Thanks! I have forwarded this info to him, and will report back when we solve it.

wow... i haven't checked out Midipipe in ages. You have added heaps of nifty stuff Nico!

I just recommended it here:
http://www.osxaudio.com/forums/viewtopic.php?p=60207

but i realised after that it wouldn't do exactly what he needs.

He needs to be able to map NRPN's to a standard CC type somehow.

Is there already a way or am i missing something?

nicowald · Post by **nicowald** » 18 Feb 2004, 13:12

hmm. NRPN's to CC makes sense (even though I don't have any devices that send NRPN's). I'll add it to the next release.

Regards, Nico
