The funny thing is, I just tried my A114 Ring Modulator for doubling frequency, and it's working just fine. I have the sine wave output from an A110 split with an A118 multiple and patched to both of the A114's inputs. I wonder what's the deal with yours? Joe ---- In Doepfer_a100

The A165 Trigger Modifier seems to be working okay as a frequency doubler in the audio range, but I don't have a scope and can't see how well it's holding up in the upper frequencies. Another possibility would be to try AM using a VCA instead of the Ring Mod. This gives you both

If you're using the DIN sync on the 808, it won't really work with MIDI sync. As it turns out, DIN sync cables - although they appear to be MIDI cables - actually use the other 2 pins of the cable. Unfortunately, I found this out the hard way. When I was syncing my Technosaurus s

What great ideas! Food for thought. Gotta try the morphing and sequential switching ideas. It's quite terrific how the Repeater automatically throws off a MIDI clock sync'd to the loop. Ideally suited to zapping into your A-190 to clock sequencer, LFOs, EGs, whatever. > -----Orig
