My first thought? Use the CR68-M-TMG to upgrade your CR-68 to a CR-78, then use a MIDI = interface with sync that=E2=80=99s intended for the CR-78. I assume that the CRX8-M supports both CR-68 and CR-78. Maybe the others = do, as well. Of course, this costs more than buying a single kit, but you get more by = spending more. (perhaps the Stereoping omits sync because that would = have added significantly to the cost) Another big problem with this idea is that you=E2=80=99d be on your own. = You probably won=E2=80=99t find any instructions on how to do this. But = if you can study the CR-68 and CR-78 schematics to learn how it works, = and take a look at the MIDI retrofits, you might be able to figure out = how to piece it all together. The obvious caveat is that there=E2=80=99s = no guarantee that an upgraded CR-68 will work exactly like a CR-78, but = it seems feasible. The uniPulse is not specific to the CR anyway, so it certainly should be = able to work with a Stereoping-enhanced CR-68. Tubbutec haven=E2=80=99t = even had their hands on an actual CR-78, but they seem confident that it = will work, so perhaps their instructions would even be applicable to a = Frankenstein CR-68+ (the same may be true of the Kenton). Note that I=E2=80=99m assuming the CR68-M-TMG has multiple boards - one = analog to add the CR-78 features and another digital for the MIDI. At = the very least, even if it=E2=80=99s all one board, it should be = possible to enable only part of the functionality (I hope). To be clear: I have no experience with any of these, other than = successfully repairing a CR-78. It was fairly easy to see how to add the = missing sounds to the CR-68, given a properly fabricated PCB. So, I=E2=80=99= m not recommended any of the above based on having tried it already. Brian p.s. This has me wondering whether the internal sequencer on the CR-68 = already has trigger outputs for the three missing sounds. Does the CR-68 = have unique patterns? =E2=80=A6 or does it have the exact same patterns = as a CR-78 with three trigger channels going nowhere?
