I just purchased some equipment to begin hiphop production..now I need some sort of setup to where I can have both my mpc and protools working together as one...and also having protools being where I finally record my tracks...can anyone help...thanks...

im actually having a similar issue...i wanna use my mpc as the master for pro-tools and cant seem to do it. id like to be able to sync the sequencers to that of the mpcs output and record from there...to make sure i catch the beginnings of tracks. any help would be greatly appreciated

You two know about MIDI? I can't judge that from your posts...

yeah...i can get it to work as a midi slave...but i cant find out how to get it to work as a master...i dont know if my problem is with the mpc or with protools...ive tried syncin the mmc and the mtc as well as the clock...nothing works....or maybe im overlooking something!?

Yes, I just wanted to make sure you know how to hook it up. But there are other folks around here who now better about the sync stuff than me.

do people really use an MPC as a master sync for protools? this seems wrong to me to have a drum machine as the master for a workstation like that. wouldn't this fukk up the digital clock? it just seems that protools hardware and software would be more reliable than a midi sequencer/sampler. any opinions?

MIDI has nothing to do with digital clock.

ok true true.... but if protools is syncing to something else via MIDI doesn't that affect the digital clock just based on the fact that the tempo(speed) of the digital audio is being controlled by the mp?

"Digital Clock" only synchronizes the signal through your Digital Out or In. So basically the sample rate of 44100 Hz. That has nothing to do with the MIDI clock, which synchronizes the tempo of your sequence.

even if you're not syncing anything, if you just run pro tools by itself there is still a digital clock that determs what is 44.1k. this is the clock in protools. some people use an external clock in there studio to stabilize the digital audio.

but if protools is syncing to an external source is 44.1 really 44.1? wouldn't the sample rate go up and down slighty to lock to the clock that it's locking to? and don't you think that could **** up your audio?

Syncing digital audio sources and syncing MIDI devices are two different things. MIDI has no effect on sample rates of audio.

i'm not talking about syncing midi devices. i'm talking about syncing protools to a drum machine. the only way for protools to adjust (speed up or slow down) to lock to the source (whether it be midi, smpte, etc.) is to adjust the sample rate. don't believe me? adjust the vso (varispeed) on a protools session and bounce it to disk. you won't hear the varispeed when you play back the bounced file because protools adjusts the sample rate to do it, so when you're playing back the file at the normal rate (44.1, 48, etc.) it just sounds like it does with no varispeed.

obviously these adjustments are all extremely minor and most likely not noticeable.

so my whole point is that i'd rather have the more stable machine (protools) as the master. but yeah it's personal preference do what works best for you.

mpc midi out to pro tools midi in vice verse on the way set the midi in pro tools as midi in pro toosl do midi to control it do channel 1 channel 1. shit is simple i ran into the same problem a while back. done deal
