Quick easy solution ★★★★★

I’ve a home studio but wanted a very quick way (if not in the studio or not bothered to turn on the DAW and hardware synths) to audition midi files on a old Mac laptop running 10.3. The Core Audio sounds are basic but you can plug it into a midi instrument and it will route midi and audio from that. I plugged a USB enabled Yanmaha portable keyboard in and immediatley got much better instruments. As Quicktime no longer runs midi this is a very affordable solution. Only improvement I can thinkis soundfont support.
