MOTU Fastlane = stuck notes for me - anybody else?

Running Logic Pro 8.0.2 on a 2.16ghz 24" iMac w 3Gs of memory, OSX 10.5.5, Apogee Duet, MOTU Fastlane, M-Audio UC-33e.

Everything in Logic runs fine EXCEPT for using my keyboard controller. I get stuck notes in every soft synth that I have tried (except for Addictive Drums). I have to hit 'bypass' to get the stuck notes to quit. These are random notes and it can happen within a few seconds of starting, or it may take a few minutes before it happens.

I have deleted my Logic pref files, deleted the old setup for the Fastlane, reinstalled the newest drivers from MOTU, have changed MIDI cables, disconnected the UC-33e, audio buffer is set at 512 (blech!), turned Bluetooth off, etc. No matter - stuck notes. When I run the MOTU Clockworks software it says it can't detect a MOTO MIDI interface. What the....?

The controller and cables work fine on my old PC with Soundblaster soundcard so I know my equipment works okay. Anybody else have similar issues? Are there any known fixes? Is there a recommended MIDI interface for the Mac + Leopard?

Thanks,
Doug

iMac, Mac OS X (10.5.5)

I've used a Fastlane on both a PPC and Intel Mac without one single problem, no stuck notes or any abnormal behavior.

Had you installed an old MOTU driver (possibly PPC only) at one time?

Thanks for replying. I originally installed the drivers that came on the CD (not sure what version that is but it does reference OS X) about a month ago but right now it says that I am using v.1.3.7, which was downloaded from the MOTU site earlier today.

Did you delete all of these before installing the new driver.

/Library/Audio/MIDI Devices/MOTU
/System/Library/Extensions/Motu MIDI Driver.kext/Contents/MacOS/Motu MIDI Driver
/System/Library/Extensions/Motu MIDI Driver.kext
/Library/Audio/MIDI Drivers/Motu MIDI Driver.plugin

Also, have you wired any (software) MIDI Cables in Audio/MIDI setup.

What about the MIDI I/O of the UC-33e? How does that fit into all this?

Last, have you tried a different USB port?

Ka-CHING! Sometimes the easiest solutions are the ones that elude us. All appears to be working now - much thanks for your help!

Doug,

Glad to hear it... something else was sharing the USB port, possibly one of the internal devices (keyboard/mouse...etc), enough to cause dropped note-offs.
I was beginning to think it was a MIDI loop but didn't see how that could affect soft-synths.

Well, it goes to show that once again user error was at fault. The iMac has 3 USB ports and 2 FW ports. Duet was on the 800 port, G Tech external drive was on the 400 port, UC-33e was on one USB port, backup drive was in another... and everything else was plugged into a powered USB multi-port extender (keyboard, mouse, Frontier TranzPort and the Fastlane!) on the other USB port. Obviously I wasn't thinking clearly when I did that set-up. I powered it down, swapped the ports for the UC-33e and the Fastlane and all is well.

So what has this taught me? Obviously I need a Mac Pro 😉 Not enough ports on the iMac!

Thanks again,
Doug
