Hi David, > Hi. My name's David and I've got a big problem with my Logic Audio Platinum. Please, sorry 'bout my English, I know it's improveable :) > > First, I list my config: > > G4/800 with MacOS X & MacOS 9.2.2, CD-RW, DVD, 40 Gb HDD. > > Logic Audio Platinum 4.6.1 & LAP 4.8.1 (upgraded from the first one). > > MOTU 2048 + PCI324 Audio interface. > > I have the same problem with both versions of LAP. I explain: > > If I put audio files in the arrange window, and I click 'play', the MIDI sequence are correctly performed, but the audio doesn't work. The extrange thing is that if I monitorize an audio file in the Audio Window or the Audio Editor... the audio plays right! > > In the first time, I thought that it could be a problem with the MOTU 2408 (it's adressed via an ASIO driver). So, I changed the device for audio in the config and in the arrange: I put the MacAV (computer beeper), and the result was the same: audio doesn't works in the arrange window, but does in the audio window and editor. You don't mention how much ram you have in your machine, but I am guessing it is more than 1 gig. This causes the crazy behavior in Logic that you are describing. The solution . . . simply allocate more memory to Logic. The goal is to get the largest unused block of system memory under about 950mb. So, give Logic 600mb of memory and all will be well. I believe this issue has been adressed with version 5.0, so we won't have to deal with this too much longer. all the best, Jon P.S. Your English is fine :-) --config-- Apple Dual 800 G4, 1.5 gigs ram, Mac OS 9.2.2, RME Hammerfall DSP, MOTU 2408, MOTU MTP AV (USB), OMS 2.3.8, Spirit 328 Digital Mixer/Controller, Apogee Converters (WC Master), ATI Radeon AGP, ATI Rage 128 (second monitor).
