Don't worry. None of this makes any difference. A 486 is fast enough for hundreds of midi channels and data streams. Anything that can run win 95 won't have any problem with more channels and streams than you could use. -----Original Message----- From: Gisle Martens Meyer [mailto:gislemm@...] Sent: Thursday, December 02, 1999 3:20 AM To: 'logic-users@onelist.com' Subject: [LUG] Optimal track use in arrange (MIDI only) From: Gisle Martens Meyer <gislemm@...> Hello, I have a performance question. I'm only using Logic for MIDI, LAWP, but I don't think that matters for the answer. What is the most efficient way to arrange MIDI data on tracks? The way I usually work is to have maybe 4 tracks pr MIDI channel in arrange, one track for the notes, one for CC07 volume, one for pan, one for modulation etc etc. Well its the way I work, don't ask :) I can quickly zoom in on the pan track and hyperdraw my changes. However, is this efficient for the Logic MIDI engine? Or should I compress everything onto one track pr midi channel, so Logic don't have to analyze umpteen tracks before sending out data? Or is it the opposite way around: The more data on a track, the slower goes Logic? It'd be great if someone knew this. Thanks, Gisle
