bermuda,

This won't do it. Read the posts by aaronk and you'll see - it's the internal parameters that are randomized and don't "line up" on subsequent playback...

This thread must be the most common question asked by almost every single person who uses Sonar for the first time.

It should say in capital bold letters at the beginning of the manual:

"YOU CANNOT RECORD THE AUDIO CREATED BY A VST OR DXi INSTRUMENT IN REAL TIME WITHIN SONAR."

It has been asked again and again and again for as long as I have been a member here.

Two things puzzle me.

Why, (if they are not going to address the issue), it has not been made a "Sticky" at the top of the the forum, and...

...why does Cakewalk seem adamantly opposed to implementing it?

I would really like to hear someone from CW give us the technical explanation of why it is apparently not possible. I presume that it is impossible to implement because they have not been able to make it happen for many, many years now. And yet they must be aware that it is possibly the most commonly asked question by new users.

This is one of the great mysteries of our time.

The people at Adobe figured it out in Audition 3.

Reaper has internal routing to solve the problem.

I am fortunate to own a Creamware Scope card and I use it's routing to send the VST or DXi audio back to Sonar for recording in real time.

So Cakewalk, what's the deal?

Hypothetically, older soft synths probably DIDN'T have the sophistication of newer ones, so capturing MIDI data probably sufficed.

Clearly, SONAR can record and play back at the same time -- a realtime bounce does this. So I have to think the only reason for not allowing a synth output to route to an audio record track is a failure to see any benefit.

I would tend to agree; I can't see any technical difficulty there at all, especially in light of some of the amazing things they already pull off. I would love to hear from Cakewalk as well as to why they refuse to implement this very usuable feature.

I admit I did not read this post through, but I think I have the solution for your issue.
Download Audacity (a free recorder/"DAW" software). It's nowhere near any serious DAW in power and features.
But it will record what the sound card outputs.

I appreciate the link. I think my solution (for now) will be to purchase Tape-It, but rerouting the Delta's ins/outs is also an option. I don't like to mess with the ins and outs though, because if you forget to put them back you can chase your tail on the next project.

It all seems so silly. If Cakewalk would let the VST out be used as an audio in, there would be no issues.

As someone who does not use much or know too much about MIDI, why would one want to do this, in practical terms? I'm not challenging it, I legitimately don't understand it, so i want to learn (preferably by scenario) why this feature exists.

Thanks!

There's an option to "reset controllers" etc.... uncheck that.



What does this do?


It prevents Sonar from resetting the controllers when restarting (ie, STOP -> PLAY).
THere's also a "searchback for patches" setting that may/may not affect what you want to do.

Record Automation (i.e. the knob, and fader movements)


This does not capture a lot of stuff (for instance the EGs in Dimentia Pro) and although we are talking about "jamming" here, you cannot copy and paste automation envelopes along with their clips.

TapeIt also has feature where it will start recording as soon as you hit play (or record) allowing you to easily resync the recorded way from 0 time or whatever bar you started recording from. It's a great time saver.

It occurs to me that, in general, allowing the output of any synth, audio or bus to be the input of an audio track would streamline a lot of things.

Yes, I know about freezing synths, bouncing tracks, applying audio effects, etc. All nice tools. But in each case, all we're doing is creating an audio track.

Why not be able to do this with a simple patch? That would be intuitive, quick, easy, and useful.

They come here arbitrarily, and only voluntarily.

For $20, if this issue is in your way, I would go ahead. They are not going to fix this one easily, I would think, and given that it's been this way since whenever, it could easily be seen as a feature, not a bugfix. Read.... S8.

jeez i didn't even know you had to pay for tape it. i'm still using v1, which is free. v2 has some cool features though. tempting..

how easily does the recorded track line up with your project after you drag it back into sonar (with v2)? just drag & drop & it lines up? or does it take more work to find the correct position?

$20 bux. I think that's good value. I know where it is for when I want it. It is so easy to use that I will grab it when I need, I think.

OK. Lining stuff up. This is moot.

Not having used Tape-it, I do not know how fast its auto-start feature works. I have been unable to download it and the guy has not come back to me.

The one I have tried actually requires manual start, then start play. So lining up is not going to be drag and drop. Probably need for a slice using Zoom way in then aligning, or sliding my project then aligning by "feel". I would need to experiment to know. If Tape-it's auto-start is really snappy, then alignment should be a "snap" <G>

However, see mudgel's reply.....that one I am going to look at.

If you have multiple outs on your sound device, can't you either

1) Internally route output channels to input channels in the sound device and then set up an audio track in Sonar to record the input

2) Use balanced cables from one set of your soundcard/device outputs , In Sonar Create a new bus output and route that output to your sound device/card second set of outputs. Using the cables from the outputs, plug into into the Sound card/device inputs. In Sonar select that as an input on the audio track, Arm it and record away.

You would have to set up multiple inputs and outputs in Audio Options in Sonar.

 Yes.

This was discussed earlier in the thread. If you go out and in you have conversions taking place. If your sound card supports the routing, that is an option UNLESS you are using those other outs and ins to record other sources. Also, it's a bit of a hassle to set up the routing and change it back.

I am fortunate to own a Creamware Scope card and I use it's routing to send the VST or DXi audio back to Sonar for recording in real time.



I use one of those too, but unfortunately there is a bit of lag when doing that, especially when you run stuff through a VST plugin, as I like to do for creating sounds. It's especially noticeable on rhythmic parts.

I tried VAC out this weekend and it didn't really work out. After installing it it showed up in my audio input & output list and i was able to route audio from one track to another. but the recording came out completely distorted and with "trial" (also distorted) every three seconds or so. I also wasn't able to select a stereo input, but i don't know if that's part of the demo limitation or not. I didn't waste too much time looking into settings or anything, as i didn't really have the time to waste, but i didn't see anything obvious to fix my distortion. so it could still work within Sonar I guess, but I'm going to uninstall it.

Another limitation I thought of while working on that particular track is that you wouldn't be able to record anything after stopping playback, as in one of my synths went bonkers with a cool sound after hitting stop while it was playing. not that Cakewalk implementing real time recording of soft-synths would capture that either, more so that this is just another reason for me to keep tape-it around.


I personally would like to be able to record on the buss tracks. Even if I had to drag the audio clip up to a new track to play it back, I think it would be a cool solution.

Its not done yet because there were a million other higher priority features that were more useful than this in the pipeline :-)
Its not a difficult thing to do but there is little advantage to recording a soft synth performance in real time when you can easily freeze the output and use the frozen data at any time. The frozen or bounced performance should be identical to the original.

Noel, thanks for the reply.

I know you are a busy guy and don't have time to read the whole thread, but it was explained at one point that with certain physical modeling synths just having the MIDI data will not result in the exact same thing playing back...apparently the synth introduces some random stuff internally so that sound will never quite be the same twice. so if you are jamming with some sounds you will want to record the result in real time.

Not an issue for me personally by it is for the OP.

The frozen or bounced performance should be identical to the original.




Noel -- Thanks for chiming in! Freezing or bouncing won't give you identical recordings in many soft synth situations. Here's an example that I don't think is particularly arcane:

Do you have Tassman? Set up a synth in which a filter is modulated by the LFO. Set the LFO to the synth's internal clock, so you can adjust the LFO frequency independent of your project tempo in SONAR. For purposes of this demo, set the LFO so the filter effects are rather dramatic (clearly and easily audible).

Because the LFO isn't synched to SONAR, its peaks and valleys can align differently (be in different phase) with the music from the original performance as compared with a bounce or freeze.

PLEASE believe me on this! I use Tassman often and encounter problems like this almost every day!

While there are various work-arounds that can solve this problem, simply being able to route a synth track directly to audio would be far and away easier than any of the alternatives. Tassman, e.g., has a built-in recorder, but every time I use it and then import the resulting .wav file back into SONAR, I resent CW just a bit for making me go to that trouble!

Am I just missing some other easy solution?
