wow! thanks for all the feedback... feel i have a better idea already....
to answer a few questions [and maybe to ask a few more], the FireWire 410 only has 2 XLR in's... the other two in's are SPDIF which I don't have cables or
any understanding of... felt a bit cheated when i bought it cos I can only use two sources at a time and not 4 as i thought [410 = 4 in's 10 outs!!!]... , anyway, so to capture more than 2 channels of audio i plan to use the Edirol as well...
i can set the levels on the R-09 for both the desk feed and the Church Audio mics seperately, but just going into one stereo mini-jack... not really mixing on the fly at all, but just capturing the SBD and the ambience of the room with the CA mics on seperate channels [left & right]....
then with the FireWire card, I'll use one Oktava [don't own a stereo pair] and one Rode shotgon mic on stage with the guitar... perhaps one mic on stage is enough...? unfortunately he uses a pickup so there will be PA bleed into the mics onstage, but I will do my best to postion both the house speakers and the mic to avoid too much of the house mix into the mics on stage.... perhaps i can persuade him to play through a mic, although its unlikely... there will be no vocals...
re: synching... in soundforge, i can stretch the other file to the exact size of the edirol files... last time i did a seperate recording with both the edirol and the firewire 410, the times were pretty much spot on i think... shouldn't be too much of a problem?
essentially i do have a 4 channel recorder to play with already... two condensor's onstage [which should give a bit of room as well] and a SBD/AUD matrix... plan to record 24bit / 44.1kHz...?
any other suggestions about my setup and plan are very welcome...? still have a week or so before the show... will only be able to record one show, so its a one off really...
