Cakewalk MIDI Troubleshooting: Finding a Faulty MIDI Cable by Swapping the Cables

Client stress // Frustrated
Difficulty // Straightforward
RESOLVED
Setup
Roland RD-700SX · Edirol UA-101 (MIDI in/out) · Cakewalk by BandLab · MIDI View
The problem
MIDI from Cakewalk played the keyboard, but nothing played on the keyboard reached Cakewalk, so no new MIDI parts could be recorded.
What I found
A broken MIDI DIN cable between the keyboard's MIDI Out and the Edirol's MIDI In. The connections themselves were correct.
What fixed it
MIDI View showed no MIDI from the keyboard; swapping the two cables made it appear. The client knows which cable to replace.

A composer’s Roland RD-700SX would play the MIDI that Cakewalk by BandLab sent it, but nothing he played on the keyboard got back into Cakewalk, because one of his two MIDI cables had failed.

He wanted to use the RD-700SX with Cakewalk for composing. He’d connected it with MIDI cables to the MIDI in and out sockets on his Edirol UA-101 audio interface, and he’d checked that the keyboard’s MIDI Out went to the Edirol’s MIDI In and the other way round. Cakewalk could send MIDI to the keyboard, so the little test MIDI regions played on the RD-700SX, but when he played the keyboard nothing came into Cakewalk and he couldn’t record any new MIDI parts. He was frustrated, because as far as he could see he’d connected it all properly.

I connected to his computer with AnyDesk, as I usually do, and we spoke on WhatsApp. The first thing I did was check that his MIDI devices were enabled in Cakewalk’s MIDI preferences. Then we went through the cabling together and he showed me his setup. It looked to me as though he’d connected everything correctly, and I wasn’t sure why Cakewalk wasn’t picking up any MIDI.

Looking at the MIDI outside Cakewalk

So we closed Cakewalk and I downloaded MIDI View, a free MIDI monitor that I use a lot. When he played the keyboard, MIDI View showed no MIDI coming in from it either.

Cakewalk’s MIDI was reaching the keyboard, so at least one of the two cables worked, and swapping them over would show whether the other one had failed.

I asked him to unplug both cables and swap them, so the cable that had run from the Edirol’s MIDI Out to the RD-700SX’s MIDI In now ran from the keyboard’s MIDI Out to the Edirol’s MIDI In, and the other one went the opposite way. When he played the keyboard again, MIDI View showed the MIDI coming in.

So he had everything connected correctly, and one MIDI DIN cable was broken and needed replacing. He was relieved it wasn’t a fault with his computer or his Edirol, and he knew exactly which cable to replace. We carried on with the rest of the session, looking at how to bring his RD-700SX further into Cakewalk, and I’ve written that part up separately in a case about setting up an RD-700SX patch list in Cakewalk.

MIDI View is free, and with the DAW closed it shows you straight away whether any MIDI from your keyboard is reaching the computer at all.

Paul reinstalled all my lost sample libraries, streamlined the storage on my computer so it works faster and fixed my corrupted disk. it took us a couple of sessions and he was friendly and patient throughout. He never made me feel stupid and never over-explained stuff I already knew - in fact he boosted my confidence. Would highly recommend. I've put him on speed dial!

Paul was brilliant, listened to the issues I had on Cubase and my home studio, worked methodically through potential problems and sorted everything. Amazing service, down to earth and explained everything so I could understand. I am a very happy song writer once again thanks to Paul! Will be using Paul again in the future and highly recommend. Thanks Paul.

Honestly, if you're in any way stuck in a creative block because of the gear you have, you've more questions than answers about what the best setup should be for your flow, or even if you have very nuanced problems in your DAW/with your gear, the service Paul provides is second to none. Besides being an extremely nice guy, he knows his stuff and takes the time to understand what you want to get out of each session and makes sure all is good to go! Can't recommend him enough!

Paul provided as stellar service, worth every penny. I came to him with a genuine issue that was affecting my Logic Pro 11 album project regarding drums and midi maps and he solved my problem most efficiently. He was patient, courteous, quick thinking and highly knowledgeable. I will certainly consider using the service again and thoroughly recommend Audio Support - Thank you Paul - you are a star :)

Working in Reaper. Super knowledgeable, friendly, speaks in easy to understand terms. Paul is helping us DAW newbies get in the game. Paul got my lost plugin files working again as well as showed me how to find missing wave files for projects that were loading incorrectly. Keep this man on speed dial.

Paul fixed in around half an hour some midi keyboard/controller problems I have been trying to solve but have had to live with for around two years! He is very knowledgeable and patient and the Any Desk link worked perfectly. I wish I had found his website sooner and wouldn't hesitate to call on his services again. Rick Grant

Paul really helped get my Cubase up and running again. He really knows his stuff, and I'll definitely look him up again when I'm stuck. Thanks!!!
