I bought this touch capacitance keyboard, a keyboard similar in style to some on the Buchla systems, in 2017, and I loved it, but immediately ran into problems, which had me frustrated and looking for answers. The main thrust was that some midi devices were not picking up the output from the midi output. It seemed as though if I plugged it directly into a synth, everything was fine, but if I plugged it into my MPC or my midi box, no messages would be picked up. This inconsistency, and the fact that Jared at Future Retro didn’t know what the solution was back in 2017, caused me to have to work around the issue, by routing everything first through my BCR2000, which picked up the signals. This was a pain in my ass for a number of reasons, with the extra cabling and delay causing annoyance and headaches.

So a few weeks ago, I had mentioned this issue to someone and they suggested I contact the manufacturer again, and when I did, there was an answer to the problem. According to Future Retro, ”

 “[T]he MIDI buffer IC in the 512 does not provide enough current drive to control all MIDI devices out there in the world.”

So it was underpowered, but worked well enough so that some things didn’t show the issue during the testing phase. Further, he writes that,

“This IC can be replaced with a different part which should resolve the issue.”

Yes! And,  the solution is that,

“You need to replace part U6 (type MC14584BDG) on the jack PCB with a part type CD74AC04M96E4.”

The U6 location IC

I ordered the part online for a few cents and then had a local tech do the replacement, as it is very tiny and this is a very expensive instrument. And what do you know, it’s being picked up by the MPC now. It’s a shame that the MPC might soon get retired, but it’s great to know that I shouldn’t have this problem in the future with any other devices. Now that this is seemingly fixed, I’ve made the setup much more compact and eliminated a lot of overhead, and now won’t hesitate at all to use many of the arp, sequence, and chord features of this controller. And it should eliminate other issues. like the delayed values being transmitted after having clock go through two devices to get to it and notes and other midi data having to go though two devices to get back to the sequencer.

A significant change is on the way…the Sequentix Cirklon, what in the electronic music world is essentially Unobtanium. I signed on to the mailing list in July of 2017, and now, on February 1st, 2021, the unit is being shipped. It is not even the same sequencer I signed up for back then, as they have updated it to what they’re calling a Cirklon 2, which adds USB host support and a color touch screen, but is otherwise the same instrument as the first Cirklon. It appears that this means that the MPC2500 may not have a very long future ahead of it. I already bought a new sampler to replace that part of it. The only unknown is if the Cirklon can send some basic sysex or not, as my TB-3 depends on that to load patches on the fly.

I have used an MPC since the very beginning, first the MPC2000XL and since around 2017 the MPC2500. It has four midi outputs, and since I have shrunk my setup,  it has worked great since I use only three synths and an audio interface. Now that the MPC might be displaced, that turns into two devices, but since the Cirklon has 5 separate ins and outs, it works out great. The Sensel Morph has an interface much like the pads on the MPC, and if they work as expected, every single  function of the MPC can be replaced. And with 5 inputs as well, I should be able to record the midi coming from any of my external devices that send information out on 5-pin DIN plugs, like the FR-512, BCR2000, or the outputs from the TB-3.

It will take some time to move everything over to the Cirklon, if in fact it will send basic sysex messages.  (I know it doesn’t support parameter changes via sysex or instrument-level sysex definitions, but maybe I can just record the track data into a regular CK pattern. Fingers crossed.) It does come equipped with what looks like a basic SMF (.mid file) conversion to CK pattern type.  The instruments will have to be assigned, and the songs reassembled, but it appears to be possible. If not, I can always play the tracks into the Cirklon from the sequencer and press record, presumably.

It represents a few things for me. One, it is a change from the platform I’ve always used, the MPC-style, to a new sequencing paradigm. The MPC hardware is getting old and has to be maintained with new parts regularly. The sampling capability is very old and I waited until I found a sampler that was a worthy successor. And, the case for the MPC now perfectly fits the Virus and Cirklon. That’s just a case, a handheld 2U rack, and a backpack with the RYTM, TB-3, and BlackBox, and cables. A very light load with a maximum of power and control with . I won’t even need a taxi anymore. Now ready to blast off into the future.
