I have a project with an ASIO source connected to the STM 1632 mixer and a ASIO dest out.

In FL Studio I have the input set to Scope In 16 bit and the Output to Scope Out 16 bit.

I have EZ Synth set up to accept midi from FLStudio and the output goes in the mixer.

I havce a MIDIOut channel set up in FL Studio with the right port settings. I press play and just get nasty feedback at full volume.

A similar arrangement works fine in Tracktion I have been able to record the output of a Scope Synth with no probs.

What's happening?

Also, what is the delay between the MIDI playback of the synth and the recorded output - is it the ASIO latency set at 2.9ms on my system?

Thanks

Sounds like there's a feedback loop. The audio you record in FLStudio might be fed back to SFP, which in turns gets sent back to the mixer, which gets sent back to FLStudio and so on. A quick fix might be to turn off the output on the recording channel in FLStudio, or to disconnect/mute the channel on the STM side of things. You could also try recording the synths/source dry output instead of the STM main/bus output.

As for the recording delay, it should be around your ULLI setting value, yes. Might be a bit longer due to MIDI lag, since software MIDI timing isn't too hot. Best way to test it is to record alongside the MIDI track in FLStudio/seqeuencer, and see how much delay there is between the MIDI notes and recorded notes.

I record this way sometimes. I have the ASIO source route through a micromixer (mixer1) and then to the audio outputs.

I have the "instrument chain" activated by FL Studio go to a micromixer (mixer2) with the output going both to ASIO destination and into mixer1.

If this isn't clear I could post a jpeg of the project.

That would be kind of you - I'm having real problems trying to record the Scope's output onto an audio track - I'm trying to do it in real time - I basically want my MIDI sequence/pattern to appear straight away as an audio track on the playlist.

Not sure what you mean there Strav...

The only way you're going to get MIDI-activated Scope instruments to appear as audio in FL Studio (as far as I know) is to play the midi sequence while FL records that sequence as audio.

You then grab the audio file and drop it into a FL track.

Is that what you mean ?

That was how I was doing it using VSTi instruments - record than load the audio file into the track afterwards. I thought there might be a way of the recorded output of the MIDI seq automatically being placed on an audio track during recording like in Cubase etc. without actually having to load the recorded audio file to the audio track.

It's a minor thing - I'm not to bothered about it really. I'll try again with the Scope devices.

It seems much easier in Tracktion to record scope synths and I don't get problems - but the same routing window setup in FLStudio and I get the feedback problem - is this a bug in FLStudio? If I have ASIO Source fed into the STM mixer and ASIO dest on the Mix Out - no probs with Tracktion -- FL Studio -- feedback????

OK, this is what I use to record Scope in FL Studio. Works for me...

It's probably not a bug (possible tho, sure), just a difference between how the applications route their signals. Given the signal path you mention, getting feedback is normal.

Basically, what happens is you send both tracks (including the first previously recorded one) to the mixer, and then record the mixer's output. Obviously, everything present at the mixer's input is going to end up at the mixer's output also. If you record the mixer's output without muting the input channels you don't want, you'll end up with both signals in there.

Muting the first track in FLStudio should let you record a second track without problem, or use the kind of routing shown in the post above.

Alternatively, you could record the source of the signal (either an instrument, or physicaly input, or whatnot) by plugging it directly in the ASIO input.

Thanks a lot I 'll try this.
