Just returning to this video because I just managed to program a beat into the CR-78 using an Arturia KeyStep Pro. I thought the info might be useful. I fired out 5v V-Trigs along to the tambourine and it totally worked. I thought S-Trig would be the one given the description of the pedal, but it worked first time and I checked the settings and I had it set to V-Trig. I'll try clocking it from the KeyStep whilst sending over various signals and see what does and doesn't work.
It's a standard 2n3906 transistor with the base connected to the trigger source and the emitter and the collector connected to the end of the cable that plugs in to the write jack. I'll try it. Hopefully, c is not e or else ... Thank you for the tip
Great info. So is the PNP transistor grounding the TS-1 signal every time there's a signal at the base of the transistor? It's similar to how S-Trigger works on an old Moog?
Thank you very much for this video. I have plugged a sustain pedal and i can play the Instruments of the CR78 but i have another problem. When i run the machine with a preset beat and i switch to the yellow ones, the machine stops. If the machine is stopped and i switch on a yellow for writing and i wanna press start, he machine didn’t start and i can’t Programm the machine. Do you have a clue? Big thanks forward
Cool tutorial. Please explain the purpose of the transistor on the write cable. I have a LinnDrum capable of 24/48/96 and would like to try your method. I can change the trigger voice by moving the cable to the corresponding voice to program, correct? Thanks!
+Tim Allen The CR-78 is expecting a switch input on the 'TS-1 Write' jack. It expects the switch to be normally closed, and to open up on the 'memory write' action. The transistor acts like a switch, opening or closing depending on the trigger voltage. I'm not sure what model of LinnDrum you have, but you'll need a programmable Trigger Output jack. I think only the LinnDrum LM-2 had that jack. You would program the LinnDrum to output a specific instrument (eg. Snare) on the Trigger Output, and then select that same instrument on the CR-78. You need to do this for all instruments in your pattern, one at a time. It's quite time consuming!
+Synthesizer Keith Cool. I have a LinnDrum LM-2, so when I have some time, I will try this. I once tried using the LinnDrum to sync with the CR-78, using the LinnDrum as master since I can see the tempo. Since the lowest setting on the LinnDrum is 24ppq and the CR-78 uses 12ppq, I had to set the tempo on the LinnDrum to half of what I wanted the CR-78 to be, e.g. 60bpm on the LinnDrum to get 120bpm on the CR-78. Any way to make this work correctly with a modified cable or am I going to have to use an external sync box? Thanks for taking your time to help.
+Tim Allen Hi Tim. You need a clock divider to drop the LinnDrum 24 PPQ down to 12 PPQ. I don't know of anyone selling one that is incorporated into a patch cable (but I might be wrong). If you are really into it, you could build a divider using 4000 series CMOS counter chips, like the 4017 decade counter, or the 4018 divide-by-n counter. Just search the web for 'CMOS clock divider circuit', there are lots of examples. It's not as difficult as you might think. Another possibility is to use a Eurorack module. There are a lot of clock divider modules, just search around. Of course, the easiest way is to set the tempo on your LinnDrum as half speed (as you are already doing).
Synthesizer Keith Thank you. What can you do with the pedal that you can't do without it? Save patterns? Sorry I know this is a basic question, especially on this video, but I am trying to understand it.
You need a pedal or programmer to write patterns into the user memory. Other than that, you can control all other features from the front panel of the machine.
Is it only the switch cap, or is the mechanical and electrical contact part of the switch broken as well? Unfortunately, these switches (and caps) are no longer made, so the only source of them is from a broken CR-78 (or another Roland product that used the same switches). You can sometime salvage a broken or cracked switch cap by using cyanoacrylate glue ("superglue"). Be careful when pulling the old switch caps off. Don't use a screwdriver, or any other metal tool, as you'll crack the cap. I normally use a plastic scraper tool, or a plastic spatula. Pull up from both sides of the cap at the same time. Go slowly and evenly!
Kieth, that beard is translucently weird and this tutorial was excellent. Don't ever change.

Thanks for posting this!
I programmed a CR-78 with a foot switch. After many tries i got a steady drum pattern.
Fantastic video Keith. Many thanks Sir.
Had one in for repair. You saved me a bunch of time! Made a quick NC switch-box for input test and it already works perfectly!
Great tutorial.
I love you. Thank for sharing!
well done. thank you!
lovely machine!
Could you use a tr-606 ? toms 5v Trig out ? using Hi tom for programing and low tom for the clock sync?
Idol!

Great video! Is there a way to use a sequencer or CV controller without a custom cable? Korg SQ-1, Keystep, etc?
John Doe hi, any news about it. i got a beatstep pro and wondering if it's possible too
tight
it is a white cap on my cr-68 2nd from left next to the grey switch

Thought i was watching the Open University......just for a moment.
Did the WS-1 come with the CR-78 or was it sold separately at the same time?
The WS-1 was an optional accessory, sold separately. That is why they are so rare.

Kieth, do you know how to replace a broken switch cap

it is just the cap head and I can pick one up on line, have you restored one before
is that custom cable a 'v trigger' cable?
i found out it's a S trigger cable. Doepfer sells this, it's blue.
Is your beard named keith or yu
syntaur is the site
Amish can use drum machines?
