MIDI stuff not loud enough

When I bounce MIDI stuff to audio, the audio is never loud enough.

My Alesis QuadraSynth is flat out and I bump all velocities to the max but the bounce is still very quiet.

I've been adding db with the Process > Audio command but there must be a better way?

I've got the MOTU Traveler interface.

Thanks - rev

    This quadrasytnh is it a real synth?

    Ie are you triggering the synth via midi, but recording the output of the synth via your Motu interface?

    If so you're probably taking outputs from the synth into the traveller line ins yes?

    There is an option on MOTU kit to boost the line ins by +4 and for some synths this is a very definitely necessary, so try that first.

    After that my sugggestion would be to use the input gain control on each channel in SOnar to bring it up.

    tell us about your signal routing from the synth to the soundcard.  exactly how do you have it connected?

    Gordon:

    I was afraid someone would say that. I'm trying not to create or require a custom setting in the Traveler just for this function. I have to admit I don't fully understand it and I'm afraid I'll screw up something that works. Looks like it's the only way though.

    Yes, the Quadrasynth +Piano is an old Alesis keyboard which I'm triggering with MIDI. It works as it should and everything's fine except for the output problem mentioned.

    Thanks!

    Right

    Well heres a tip, MOTU ships everything witha  think called Cuemix its a graphical representation of the mixer within the Traveller accessable from you're computer.

    It enable you to change configurations from your PC really easily when its hooked up to the motu via Firewire (a lot easier than navigating via the knobs on the Travellers faceplate trust me)

    Open cue mix, you will see all the available channels/inputs, locate the ones you are using for you're keyboard and you will see that there is a -10 and +4 buttons above those channels, check that the minus 10 is not clicked (could also be the source of you're problem) and then check +4.

    Seriously this is the easiest and quickest way to rectify you're problem and its really worth learning the cuemix software becuase you can get a lot out of it in terms of doing 0 latency monitoring and other cool tricks. Its not that scary really, it looks very similar to the mixer set up in Sonar, only less complicated :)

    Open cue mix ... and then check +4.

    That's the best solution, revnice. I have to do that with my MOTU interface for all my synths if I'm coming in over audio rather than S/PDIF. Although it probably doesn't hurt anything by using Process -> Gain to boost the levels, as long as the synth's output is reasonably noise-free, adding the gain in the interface itself saves you that extra step.


    All else is in doubt, so this is the truth I cling to.

    I have a Nonasyth which is pretty much like the Quad. I don't bounce it, I record it. In fact, how do you bounce the Quadrasynth?  Doesn't your sound come analogue from the synth? I also have the problem that the volume is low in spite of running it through a mixer and boosting. Too much boosting distorts it. Solve it by normalizing after recording it.

    I think he meant "recording", John. And while it's true that setting the interface to +4 could cause distortion in some synths, the majority of pro and prosumer synthesizers in the world (e.g. your P-70) are line level +4 devices. It also depends on the audio interface, and how much headroom it provides. I can clip my MOTU 828MkII if I try, but not easily.
