Hi, I'm having a real hard time getting the IAC bus to work as MIDI conduit between Logic and Kontakt standalone. If there's anyone who can help, I'd greatly appreciate it. I have Kontakt up and running and being successfully triggered from that little MidiKeys utiliy over the IAC bus — no problems at all. As soon as I quit MidiKeys and launch Logic; select a midi instrument; set it to transmit midi on the same IAC bus (just like I did with MidiKeys) I get blasted with this HUGE feedback loop that can only be killed with a force quit of Kontakt... What is going on?!? I've stared at the problem for hours and I can't figure it out at all. But it's the same every time I try to make the connection. Kontakt has a MIDI tantrum. Kontakt is set to have the IAC Bus 1 as its "input" Midi channl — all others are toggled off. It has no output channels active. As I said before, it likes it when MidiKeys talks to it... IAC only has one bus. Logic is just opening a standard, factory template. I'm so confused I had to quit and walk away. Hoping someone can shed some light...

Logic will also receive anything sent to it (Logic listens to all ports), so if the sending instrument is the selected track in the Arrange, you have a loop. Block the IAC port outlet at the environment Physical Input (cable to dead-end monitor or such). This will prevent messages from the IAC bus reaching the Arrange. Note that if you're using Logic Express, you're screwed - there's no way to block one port. In this case, MIDIPipe should be used rather than IAC.

That was the problem, plain and simple. I had no idea. Blocking the port, eh? Who knew? Thanks again.

Even cabling a monitor on the inputs is making Logic going mad Best Cyril

The solution might be to turn off the auto-sync, which I think is in tempo & sync prefs (song prefs?)

Logic is OK now, but external K2 does not follow tempo changes ! Many thanks Cyril
