Non-disconnected parts Visitor	Virtual MIDI port: What's the Deal?logic - 2005/05/02 15:58 Why is it that for every instance of Musolomo in Logic a new Virtual MIDI port appears in my "physical input" object? What's it for? Can I loop MIDI sequences? Somewhat related... I'm trying to develop a very simple Pluggo (I know that's not your bag) that generates and transmits into Logic's environment MIDI data by analyzing incoming audio. But I read somewhere that AUs cannot generate MIDI data like this. I was wondering if the appearance of the mysterious Musolomo virtual port might dispell what I read as a myth. Can you clarify?

Re:Virtual MIDI port: What's the Deal?lo - 2005/05/02 16:27 that port is for some currently-being tested feedback engine - haptic feedback for control of audio.

we left it in there by mistake.

It is possible to make an audio unit output midi, but only by setting it up as a virtual midi port - this is in fact how apple tells you to do it, my developer tells me (if i remember correctly.)

what is it your plugin will be doing?

non-disconnected parts Visitor	Re:Virtual MIDI port: What's the Deal?lo - 2005/05/03 01:06 Thanks for your response. The plug I'm working on does a very simple thing: it analyzes the volume of an incoming signal and converts the levels to MIDI CCs, and then it pass the audio thru. It's to be a utility for live gigs. I want to have a completely digital rig but I also want a sound guy to tweak the levels of the band from the floor where the audience hears. The master computer with all instruments and MIDI controlers plugged in is on stage to save in cables. The sound guy in the mixing booth with a laptop. The master computer and laptop have a MIDI connection via ethernet. The laptop is running a Max patch with various faders and knobs to control various parameters of Logic on the master computer via MIDI. Where my custom plug-in comes into play is that it enables the soundguy's laptop to have VU meters. As volume on each track varies, so too does MIDI data, which is transmitted to the soundguy's laptop and redisplayed as a VU meter.

Re:Virtual MIDI port: What's the Deal?lo - 2005/05/03 09:57 thats a pretty hardcore way to do it

But that plugin would be useful for LOTs of other things too, vocode-like effects, controlling parameters with your voice, etc

how much latency is on that plugin?

non-disconnected parts Visitor	Re:Virtual MIDI port: What's the Deal?lo - 2005/05/03 14:42 There's like no latency. Is there a handy utility to calculate this? It was a little tricky but I rigged up Logic to determine this. Check it: http://users.rcn.com/r.ephraim/sounds/remotevuvsclean.jpg The top wave is the track with my remoteVU Pluggo. The track on the bottom is a clean track. It's zoomed a lot and the waves line up perfectly. As with any good experiment, check out the "control subject": http://users.rcn.com/r.ephraim/sounds/reverbvsclean.jpg This is the same setup but instead of the remoteVU Pluggo I inserted a reverb. The latency is obvious, and it's not even zoomed as much. Anyhow, this is threading over at OSXaudio. http://osxaudio.com/forums/viewtopic.php?p=180956#180956

olivier Visitor	Re:Virtual MIDI port: What's the Deal?lo - 2005/05/06 02:55 do you know VNC? with it you could just remote your stage computer from the audio guy computer. I use it thru airport , latency is no that bad. you can find VNC for PC, MAC, pocekt pc,linux and palm desktop. have a look at versiontracker.com. olivier
