Trigger a DAW or simple OSX sampler to record then playback sample with midi

My subjest says it all. I want to be able to setup a DAW or sampler (preferably a simple and free one) to begin recording when triggered by midi. Then, I want it the very same sample with a midi signal. I'd also like that piece of software to be free or very low cost.


Midi will be sent via Qlab through MidiPipe.


Any help would be greatly appreciated!

is the sample a live voice, music or from another source?

how long will the recording/sampling be?

how many?

do you want to press a midi key and record manually or does the audio initiate the recording?

when recorded, are you wanting to playback the exact same recording, or will it need to change in any way?


I can't guarantee an answer to your post but if you can provide these answers to the above it may help another reader get you sorted out.

Thanks for the reply. I have found my solution for this, but here are the details as I'm sure there are better, new or more efficient ways to execute this. Ansers to your questions:


It is live voices picked up through a mic onstage.

The sample is 10 to 15 seconds long.

It is a single sample that will be played back once.

I want to trigger it with a midi signal from QLab 2.

I want to have a high pass on playback.


I'd love to know your thoughts. For the moment, this is how I solved it:

I have the mic plugged into my MOTU with a highpass on the input

The signal is routed to Mobius (looping freeware)

Mobius's recording, pause, play are all seperate triggers from QLab

looks like you've sussed it well enough for now. as i said, it's not quite my bag, but it's an interesting puzzle all the same.


i'm intrigued. can i surmise this is not a rhythmic based production? as you're not looping.


actor speaks/sings

actor recorded

recording plays back, at some point, on demand.


it happens one at a time, or multiple? (multiple would be hard unless each actor is mic'd up individually)


i showed this post to a theatre friend of a friend and they thought it looked perfectly viable (your method).

Thanks for the reply!


Yes, it is actually a fight that happens on stage that gets video recorded. In a later scene, we see actors huddled around a monitor watching the screen and we hear the playback.


It happens once and only lasts for 10 seconds (although we record a lot more so we don't get forced into a loop) and is captured through a shotgun mic above the stage. It was bit of work for such a small bit that no one may ever even notice. The obvious backup was to just use a prerecord which we actually keep cued up in the show in case the mobius does not fire.


There are many ways to do this (we could have just used quicktime to record and playback), but the show is filled with sound and light cues, and we only have one operator so it was imperative that whatever we did, we kept everything in QLab (no switching software mid show).
