Deconstructing LP1 LoopBegin and Quantize replace issues

[William Walker <billwalker@baymoon.com>]

 Like you Phil I have had mixed results using my DAW clock to midi  
Sync my LP-1, If I'm doing normal loops and I'm using the technique of  
pre arming the tracks by hitting a play stop command as I move to each  
new track (and I'm aware for where my 1st loop start point  is when  
recording my next track) things will stay pretty stable, though i  
might get some drift over time.  When using  multiple tracks of  
quantize replace, its much more difficult for them all to stay synced  
to an external clock source, i suspect  because the very nature of the  
technique has timing considerations due to the slight delay while the  
microprocessor is initiating the command, add those milliseconds up  
when you keep building a track using this technique and what you  
thought was your downbeat pulse is no longer.  Its also so easy to get  
carried away in the process of creating the note sequences that one  
simply forgets where that loop point really is. Compound that with  
creating multiple tracks of this stuff and wanting it all to slave   
and be hunky dory with your DAWs midi clock is a tall order. One thing  
I have found to be true is i get better clock results if I mute tracks  
rather than stopping and starting them, and group commands where  
multiple tracks are being turned stopped and restarted only serve to  
create further midi clock drift if it is acting as the slave .  Also  
if I'm in doubt of my downbeat on a track as relates to the master  
clock track, stopping it,  and restarting it by initiating a replace  
command (yep, if a track is pre armed and stopped, you can restart it  
with a replace command)   can help to realign the two tracks to some  
degree. lastly  i've worked hard at learning to initiate Q replace  
commands on the beat that anticipates the beat i want to replace so if  
i have a quantize  replace factor of 16th I'll initiate my command a  
little a head of schedule on the 16th beat to have it arrive on the 1.
