Received it a couple of days ago for a fair price - still trying to figure out,
how to use the sampling functionality (was so far not successful with auto record/ playmode A).
Will try trigger mode b+c today (could this just be an audio signal - or do I have to use triggers?)
Anybody else using this strange little box?
(The RPS-10 pitch shifter delay is far more straight forward here in terms of usage).
Cheers

I can’t help but just wanted to say that this is also one I’ve been looking around for. Nice that you got a good price as they are a good deal more than any of the others in the series here in Japan and not that common.
You probably know it, but this tune is named after it.
PS: Does it power off a standard guitar adapter or does it require a special power supply?
I’ve had both of those from their release (plus Comp and Graphic EQ) … 80s throwback pic alert!..
i don’t recall it being too problematic (some old boss pedals are 12v, just check it’s not a 12v/9v thing) but i used it more often as a delay
If you are still having issues I can try out a similar configuration so you have an A/B comparison to gauge whether yours is behaving properly
just grabbed the box - defo 9v !
I’m not sure what your expectations are to sample. You need to use the trig inputs for precise rec and playback control, auto can get unwieldy. Or just feed the output back into the keyboard for some pen expers style mad sounds. Tip is input levels should be kept low.
oh yeah and i cut a trace on mine so the output is totally wet. this is real game changer as it’s pretty restricted as an FX send without it, but adds a bit of hit and miss to auto sampling if it’s your only monitor source.
fwiw
one thing to be mindful of is that it’s maybe helpful to re-arm Mode A by rotating it one way and back
After that, a simple momentary switch in the trigger will suffice to play back
or a lowish level impulse
or if you have a gated source/recording of pure notes and feed that to the tape/key input it will trigger from the incoming pitch change
the frequency on my signal generator suggests the C nearest 520Hz is the nominal neutral frequency, it can go up to appx 2.4KHZ and down to inaudible
so 2 octaves + up and many more down, well into crunch/mush
if you feed an oscillator signal in, you can still trigger from the switch input
note that the jack for keyboard input is switched to remove tuning functionality from the front panel (it also bleeds a tiny bit into the audio path)
plus, if the first pot is full anticlockwise it’s a short buffer that gets slower as you lengthen and vice-versa (all if there’s no pitch setting this in the rear)
it’s colourful for sure
Thank you all for your help and replies!
Will it overwrite immediately?
Or when do I trigger recording / playback in mode a)?
Also not sure, what’s the difference between mode c) and d)
Tried to sample 808 percussion, Cy,Toms,RS,Hats and so on - used trigger out from CL of the 808 into trigger in - but wasn’t able to spot any differences between b)+c). Also the rec LED flickers only occasionally in a non-reproducible way (?). Delay modes are working perfectly well.
I am going to try with a different setup tomorrow. 
Is the rsd10 an influence on the UW ram machines ?
Re-arming doesn’t clear the buffer, iirc you will hear the last buffer as you record the new one in, even if overdub/feedback is minimum
In mode A it’s a threshold recording, no need to trigger
Fwiw, whilst in Mode A you can trigger from there too without touching the buffer
For c and d playback, I hadn’t confirmed, but I expect c will play the whole buffer whereas d will play whilst the ‘signal’ is high … I say signal as I’m surmising it’s for when you feed in a tuned pitch
As I mentioned, turning on a signal generator will '‘trigger’ playback (no switch required) … I’m not sure if gated will also work with the switch, i.e. trig detects switch closure onset and gated tracks the switch closure duration … the other input for a pad is looking for a voltage impulse, I guess from primitive drum pads … when I put the clock from a volca in this it was loud, so probably quite sensitive
Don’t experiment with modular gear here if not sure …hopefully it’ll all fall into place at your next try
Just adding these links here for convenience …

Nice score! I have an RPS-10, and there’s more to it than meets the eye. You can among other things play the pitch shifting with an external keyboard. Lots to play around with, and it has a gorgeous grungey sound to it. There are some youtube demos demonstrating its less obvious capabilities. Have fun 
i always thought this beat was computer dsp madness but could it just be drums through some computer controlled (sequencing the kb in) boss miniracks!?
Thanks a lot for offering your help!
I don’t get it:
In Mode A:
In Mode A I wouldn’t try to trigger recording, it’s done purely on Audio threshold
Maybe the best thing is to try one later at a time … threshold recording
Then add the key input to repitch it
But don’t reselect Mode A as this will rearm recording
Then try triggering playback with a switch
When I triggered via a switch it would not restart the recording afaict … in most cases I have high feedback anyway
The only way I could empty the buffer was reselecting Mode A from another mode
It’s packed away again, but if something seems broken I can do a check
