Strange MIDI Signals

When I record my LP in Logic something really weird happens:

As soon as I turn the oscillator knob or the modulation knob it sends some weird remote control commands to Logic which causes it to either mute, solo or modify the panorama settings on the track i am recording.

Any idea how to avoid this? (And yes, i have the latest firmware on my LP)

If the LP is functioning correctly, then Logic is somehow responding to the MIDI CC’s that the LP is sending. Since there is way way to turn off MIDI CC’s on the LP, you’d have to filter out the messages in Logic.

To assist further in troubleshooting this problem, grab a copy of MIDI Monitor from snoize.com. Set it up to spy on the LP’s output, and monitor what Logic does in response to making changes on the LP. This will tell you exactly which commands causes Logic to misbehave.

i am getting “pan (course) [value]” on the oscillators knob and
“data entry (coarse) [value]” or “controller 3” on the modulation knob resulting in muting or soloing the recording track.

i don’t know how to filter this in logic. i also don’t know how to route it that the actual correct action is being transmitted. (so it plays it when playing the recorded sequence back).

none of my other 6 synthesizers are showing such a behavior on default in connection to logic.

The LP sends oscillator 2 frequency out channel 10, which is used as PAN by lots of devices. The modulation amount goes out channel 6, which is the data entry course channel.

You could change the midi out channel to some other channel so it does not mess up your other devices. Of course the midi notes will go out that channel but maybe Logic could be set up to change the mapping to the correct channel.

i have set channel in and out on the LP to 1. same goes for the the settings in the environment in logic.

however, i did find out that by default all my hardware synths were set up as multi instruments. even though only one channel is activated i should not get additional signals through other channels…

i changed the multi instrument then to a “regular” instrument - and that finally was the solution. :slight_smile:

I am using my LP with Logic.

I have it set to Local Control Off and the MIDI channels both set to 1.

I m using it via the AMT-8, which lets me have it on it’s own port.

It can send to any active channel in Logic, so I can control OSCar, JP6
and the rest.

I am not getting the MIDI messages you are seeing, although I can send
them to Logic automation. But then because I use the AMT, I have
been filtering all the stuff I don’t want. Logic filtering is crude and you
really need a proper interface to thin out MIDI data. I have tried setting
up a few CC’s with the Phatty in Logic, but I’m not quite happy yet.

What I plan to do is create an Environment for the knobs in the Phatty
so you can just assign them on the fly with a Menu, but that won’t be
until I learn it all yet!
