Logic Pro 7 & earlier Logic 4.8 (for PC!) No audio on channel 25+


New Member
I've just been recording/editing a track and I'm using more than 24 tracks. On tracks 25 and upwards no audio is playing and I can't work out why. I'm presuming I've never gone above 24 tracks before, surprisingly.

I'm using the last version of Logic for PC so I realise it's a little out of date, but it's working fine otherwise. I'm presuming I have to set up something for tracks 25+, possibly in the environment, but I can't find anything in the help section or doing online searches.

Any help much appreciated.
