Delete or select channels for playback in a MIDI track

Hey guys,
 
Long time no see!
 
I've got a problem. I bought a midi track from HitTrax and loaded it into Sonar 7.
 
I'm trying to seperate the instruments into individual tracks to use the best synth for each instrument.
 
I copied the track to several synth tracks which of course copies the notes from every channel. I'm trying to use the PRV to either select just a certain channel for playback or delete all the notes except for the specific channel I want to use in that track. I thought I could just copy the track and select the channel output for the instrument I needed but that does not seem to be working in some of the playback programs.
 
I guess the easiest and most desirable solution would be to delete all the notes in a specific channel. That way I could delete all the excess, leaving only the notes I needed for the intended instrument.
 
Anyone know how to do this?

The interpolate function can be used for this, even though it doesn't have a delete function. What you can do is use it to select every event in a specified channel or channel range and change those notes to something outside the range in the file, such as c0. Then it's easy to select c0 in the PRV and delete them.

digipenguin,

First, if the file is in Standard MIDI Format and .smf is 'associated' with Sonar, then double clicking the file should open it in Sonar in the SMF format with 16 tracks for the 16 channels.

If that doesn't work, then there is another way to separate the files, similar to bitflipper's suggestion. Here is a description of how to do it with a track that has 2 MIDI channels on it, which is easily extended to additional channels (Note - you need to know what channels are recorded in the track. For this example, assume it has channels 1 and 2):

1. Make sure you have as many empty MIDI tracks available as you have channels of data in the original track.
2. Select the original track data and click Edit>Select>By Filter.
3. Accept the defaults for everything but Channel. Change the Max Channel number from 16 to 1. Click OK. This copies all Channel 1 (and only Channel 1) data from the track.
4. Select the first empty MIDI track, make sure the Now indicator is set to the same setting as the start of the original MIDI data. Press Control 'v' to paste the channel 1 data into the track.
5. Repeat steps 2, 3 and 4 for the remaining channels, adjusting the MIN and MAX Channel numbers to 2 (or whatever channel data you are copying from the original track).

I hope this helps.  Good luck.
