Other than sufficient powering and SINAD to accommodate a pair of DPA CORE 4060 [the baseline go/no-go performance metric for me], the critical functionality for my use will be if two or three of them can be sufficiently sync'd and controlled while in pocket, using the software below or something equivalent to it installed on my phone..
metarecorder can do this but not elegantly, via its master/slave mode. they are all clocked independently though, same as the deity PR2s would presumably, as time code sync is not the same as word clock.
not elegant because you need a separate phone for each 2 channels. i think only the teenage engineering unit that hoserama runs fits your bill but thats a monster with a price to match
Right. I've no interest in recording to 2 or 3 separate phones, which I could do using DPA d:vice. I was long hoping for some way of connecting 2 or 3 d:vice's to a single phone. Or a follow up d:vice version that featured a card slot able to recorded locally, but with collective control over several. The speculative strategy of recording using 2 or 3 PR-2's that are collectively controlled by a single phone is based on that. Nice to have the storage local, only remaining problem if that works is clock-sync.
Non-fully sync'd clocks is unfortunate, yet
hopefully easily manageable, which is the key to this working as envisioned. Yes timecode is not wordclock. The difference between frame rate and sample rate is around 2 orders of magnitude! However, I've found modern clock chips, especially in gear which features timecode to free-run with a quite tight tolerance, particularly when its the same chip in identical recorders. I'm holding out hope the drift will be minimal, perhaps inconsequential over the course of one set of music.

Getting into the weeds on this a bit- In one potential arrangement I'd need 5 channels total, 3 of which need be closely phase-correlated. One way of checking / assisting alignment is using the pass-thu feature to duplicate one channel from the first recorder which is recording two mic inputs to one channel of the second recorder that's only recording one mic. The duplicate track can then be used to confirm sync, and if necessary assist with stretching in a very accurate way (invert phase and sum with the duplicate, alignment achieves deepest null). I've done that a couple times using two four-channel DR2d's to record 6 channels by routing the headphone out from the first recorder to one of the two stereo inputs on the second recorder, duplicating that pair between the two recorders. Technically this incurred a very slight but constant latency offset due to the DA/AD step between the first to second recorders. But that wasn't a problem, and if it were it would be easily measurable and would not change. Of course, I'm hoping that's unnecessary, but its a work around.
