Viscount R64S
PCM drum machine (198x)

 

Italian preset drum machine based on really lo-fi 8-bits samples with rhythm patterns.


The "S" version is a minor hardware revision from previous R64, but it seems to be the same with no noticeable differences.

edit SYNC the trigger option syncs analog machines like other drum machines or synthesizers arpeggiators.

I tried to slave both R64 and Roland Juno-60 and worked flawless.
Note that you can change the OUT dividersvalues on the back panel switch to match the wished tempo. Juno60-R64 Sync on the DEMO section.
This function allows to make some pretty interesting and fun jam session with many compatible hardware, and best of all, the timing is perfect, much more better than classic Midi clock.

TECH typical issues are buttons that need cleaning as well as pots.

Model PCM64 and PCM64S are quite similar with just some minor differences on the board, but they do sound the same.

REVIEW: "A fun but very limited box, but sync option is nice for sure. Resin- enclosed voice board is a big trouble for future repairs."
