Instantly Playing Music Cues In Os X Options

[AlanAudio]

In OS 9, I used to use a very nice feature of Bias Peak, which allowed me to have ten open windows with music tracks and to fire one of them instantly and without warning by pressing a numeric key. I used it to play music cues within unpredictable live TV programmes.

I'd like to do something similar on OS X. I'm sure that Bias Peak still has that feature, but would be interested to know of any alternatives, maybe ways to achieve the same functionality in Logic Express.

The requirement is to be able to load in anything up to 30 music selections and to have the means to rapidly set a number of them up so that they are available to be played on demand. From time to time it might be appropriate to re-select which cues are available for instant use.

If there were also the option of being able to play more than one feed at once and fade between them, that would be excellent.

It would also be desirable to opt for a second track to stop the preceding one and then play in it's place.

What I'm looking for could possibly be achieved by a music app, a sampler, a cart machine emulator or a DJ app.

What would you suggest ?
