Rack Filters/passing MIDI from external sequencer

[droolmaster0]

I haven't been able to figure this out.

I have a p3 sequencer, and I can use it to send MIDI to either vst instruments or send it through to an external synth. I am having a problem with the second of these.

If I simply select the p3 and send its output to the external synth without a rack filter, everything is fine (well aside from the fact that MIDI clock is screwed up in Tracktion).

However, with a Rack Filter the MIDI goes bezerk. Timing, triggers - it just doesn't work. I suspected some kind of MIDI loop, but there doesn't seem to be one.

I set it up with just one track taking MIDI in (from the P3) and the rack filter doing nothing but passing the MIDI to the external synth. but it just doesn't work. I want to use a rack filter for this since I want to control various items with the p3, and I don't see a way to use the p3 for multiple tracks using different channels unless I use a rack filter.

EDIT: After playing around some more, I'm starting to conclude that the problem is the following. I'm not sure how to get around it. If you want to use a rack filter to pass MIDI through to the output, you need to select the midi output for the track, or else MIDI doesn't get sent out at all. But if I do select it for the track, it sends it twice - once for the track, and once for the rack filter. So, at best I get flanging, and at worst it goes haywire. I'd sure appreciate a solution to this. I'm almost at the point of giving up on Tracktion for now.

Right now I'm finding the MIDI routing portion of the rack filter *and Tracktion in general) to be very inflexible and unreliable, but I'm hoping this is user error. While Bidule lacks the linear recording features in Tracktion, you can use its modular interface to route MIDI the same way you would audio. I wish Tracktion had implemented this.
