Ok, I received the PPS-100 today and after some testing, I can see there is an unavoidable issue with variable frame offsets
There is a disparity between frame rate used by vst's internal sync and how the PPS-100 calculates Midi clocks from SMPTE frame rate, and this means the converted Midi Clocks begin transmission at Cue Start(punch in) with a varying frame offset that is required to lock with the bpm of the DAW. This offset depends on what starting bar/beat and what bpm you use in your DAW, and varies between -4 and -7. To convert SMPTE to Midi Clock reliably, you're stuck with 24 fps, so that's at least a constant in your project.
You are forced to adjust Cue Start time based on tempo anyway, but one is also forced to adjust frame offset, and you have to keep guessing this value until you nail it every single time you change Cue Start time or bpm
It's just too bad you can't adjust frame offset while the conversion is running.
What's also annoying is the PPS takes about 2 seconds to reliably start converting SMPTE to Midi clocks from first transmission, so you have to also take this into account for your Cue Start time.
It has so far shown rock solid timing, once you get past these hurdles. Only bummer is the Pulse out cannot be used for clocks to Roland or other 5V pulse clock inputs. There just isn't enough drive from the PPS-100 for it to work.
Sync24 tested good, but you do need to either be mindful of Cue Start time or have a blank pattern if the Roland device isn't meant to start when something else does.
Viewing angle on the display is also pretty limited.
I can see why Innerclock charges an arm and a leg for painless operation. This conversion is more complex than it appears, but more importantly, there is no real competition for the demand they meet, so they can charge whatever they feel like charging.
I am no longer in pursuit of vintage synths. The generally absurd inflation from demand versus practical use and maintenance costs is no longer viable. The internet has suffocated and vanquished yet another wonderful hobby. Too bad.
